Medial cutaneous nerve of arm
The medial brachial cutaneous nerve is distributed to the skin on the medial brachial side of the arm. It is the smallest branch of the brachial plexus, arising from the medial cord receives its fibers from the eighth cervical and first thoracic nerves, it passes through the axilla, at first lying behind, medial to the axillary vein, communicates with the intercostobrachial nerve. It descends along the medial side of the brachial artery to the middle of the arm, where it pierces the deep fascia, is distributed to the skin of the back of the lower third of the arm, extending as far as the elbow, where some filaments are lost in the skin in front of the medial epicondyle, others over the olecranon, it communicates with the ulnar branch of the medial antebrachial cutaneous nerve. The term nerve of Wrisberg has been used to describe this nerve. However, the term "nerve of Wrisberg" can refer to the nervus intermedius branch of the facial nerve.

The pectoralis minor is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major in the human body. It arises from the upper margins and outer surfaces of the third and fifth ribs, near their cartilages and from the aponeuroses covering the intercostalis; the fibers pass superior and lateral and converge to form a flat tendon, inserted into the medial border and upper surface of the coracoid process of the scapula. The pectoralis minor muscle is covered anteriorly by the clavipectoral fascia; the Medial pectoral nerve pierces the clavipectoral fascia. In attaching to the coracoid process, the pectoralis minor forms a'bridge' - structures passing into the upper limb from the thorax will pass directly underneath. Axillary nodes are classified according to their positions relative to the pectoralis minor muscle. Level 1 are lateral, Level 2 are deep, Level 3 are medial; the pectoralis minor divides the axillary artery into three parts - first part medial, second part deep/posterior, third part lateral in relation to the pectoralis minor.
The origin is from the second and fourth or fifth ribs. The tendon of insertion may extend over the coracoid process to the greater tubercle, it may be split into several parts. Absence of this muscle is rare but happens with certain uncommon diseases, such as the Poland syndrome; the pectoralis minor depresses the point of the shoulder, drawing the scapula superior, towards the thorax, throwing its inferior angle posteriorly.

Common palmar digital nerves of median nerve
In the palm of the hand the median nerve is covered by the skin and the palmar aponeurosis, rests on the tendons of the Flexor muscles. After emerging from under the transverse carpal ligament the median nerve becomes enlarged and flattened and splits into a smaller, a larger, medial portion; the medial portion of the nerve divides into two Common palmar digital nerves. The first of these gives a twig to the second Lumbricalis and runs toward the cleft between the index and middle fingers, where it divides into two proper digital nerves for the adjoining sides of these digits.

The axillary nerve or the circumflex nerve is a nerve of the human body, that originates from the brachial plexus at the level of the axilla and carries nerve fibers from C5 and C6. The axillary nerve travels through the quadrangular space with the posterior circumflex humeral artery and vein; the nerve lies at first behind the axillary artery, in front of the subscapularis, passes downward to the lower border of that muscle. It winds backward, in company with the posterior humeral circumflex artery, through a quadrangular space bounded above by the teres minor, below by the teres major, medially by the long head of the triceps brachii, laterally by the surgical neck of the humerus, divides into an anterior, a posterior, a collateral branch to the long head of the triceps brachii branch; the anterior branch winds around the surgical neck of the humerus, beneath the deltoid muscle, with the posterior humeral circumflex vessels. It continues as far as the anterior border of the deltoid to provide motor innervation.
The anterior branch gives off a few small cutaneous branches, which pierce the muscle and supply in the overlaying skin. The posterior branch supplies the posterior part of the deltoid; the posterior branch pierces the deep fascia and continues as the superior lateral cutaneous nerve of arm, which sweeps around the posterior border of the deltoid and supplies the skin over the lower two-thirds of the posterior part of this muscle, as well as that covering the long head of the triceps brachii. The motor branch of the long head of the triceps brachii arises, on average, a distance of 6 mm from the terminal division of the posterior cord termination; the trunk of the axillary nerve gives off an articular filament which enters the shoulder joint below the subscapularis. Traditionally, the axillary nerve is thought to only supply the deltoid and teres minor. However, several studies on cadavers pointed out that the long head of triceps brachii is innervated by a branch of the axillary nerve; the axillary nerve supplies three muscles in the arm: deltoid and teres minor.
The axillary nerve carries sensory information from the shoulder joint, as well as the skin covering the inferior region of the deltoid muscle - the "regimental badge" area. The posterior cord of the brachial plexus splits inferiorly to the glenohumeral joint giving rise to the axillary nerve which wraps around the surgical neck of the humerus, the radial nerve which wraps around the humerus anteriorly and descends along its lateral border; the axillary nerve may be injured in anterior-inferior dislocations of the shoulder joint, compression of the axilla with a crutch or fracture of the surgical neck of the humerus. An example of injury to the axillary nerve includes axillary nerve palsy. Injury to the nerve results in: Paralysis of the teres minor muscle and deltoid muscle, resulting in loss of abduction of arm, weak flexion and rotation of shoulder. Paralysis of deltoid and teres minor muscles results in flat shoulder deformity. Loss of sensation in the skin over a small part of the lateral upper arm.

Medial cutaneous nerve of forearm
The medial antebrachial cutaneous nerve arises from the medial cord of the brachial plexus. It derives its fibers from the eighth cervical and first thoracic nerves, at its commencement is placed medial to the axillary artery, it gives off, near the axilla, a filament, which pierces the fascia and supplies the integument covering the Biceps brachii, nearly as far as the elbow. The nerve runs down the ulnar side of the arm medial to the brachial artery, pierces the deep fascia with the basilic vein, about the middle of the arm, divides into a volar and an ulnar branch; the volar branch, the larger, passes in front of, but behind, the vena mediana cubiti. It descends on the front of the ulnar side of the forearm, distributing filaments to the skin as far as the wrist, communicating with the palmar cutaneous branch of the ulnar nerve; the ulnar branch passes obliquely downward on the medial side of the basilic vein, in front of the medial epicondyle of the humerus, to the back of the forearm, descends on its ulnar side as far as the wrist, distributing filaments to the skin.
It communicates with the medial brachial cutaneous, the dorsal antebrachial cutaneous branch of the radial, the dorsal branch of the ulnar.

Loyola University Chicago
Loyola University Chicago is a private Catholic research university in Chicago, Illinois. Founded in 1870 by the Jesuits, today Loyola is one of the largest Catholic universities in the United States. Loyola's professional schools have educated generations of local business and civic leaders, distinguished programs in medicine and health sciences are anchored by the nationally recognized Loyola University Medical Center. Comprising eleven colleges and schools, Loyola offers over 80 undergraduate and 140 graduate/professional programs and enrolls 16,000 students. Loyola has six campuses across the Chicago metropolitan area, as well as a campus in Rome and guest programs in Beijing and Ho Chi Minh City; the flagship Lake Shore Campus is on the shores of Lake Michigan in the Rogers Park and Edgewater neighborhoods of Chicago, eight miles north of the Loop. Loyola's athletic teams, nicknamed the Ramblers, compete in NCAA Division I as members of the Missouri Valley Conference. Loyola won the 1963 NCAA men's basketball championship, remains the only school from Illinois to do so.
The Ramblers are two-time NCAA champions in men's volleyball. Among the more than 150,000 Loyola alumni, there are executives of major Chicago-based corporations such as McDonald's and Baxter International, as well as dozens of local and national political leaders including the current Illinois Attorney General and Speaker of the House. Loyola alumni have won Emmy, Grammy and Pulitzer awards, as well as Guggenheim and MacArthur fellowships. Loyola was established as St. Ignatius College on June 30, 1870, by Jesuit educator Fr. Arnold Damen. At that time Chicago was a much smaller, but growing, city just shy of 300,000 people, as a result the original campus was much closer to the city center along Roosevelt Road. In 1909 the school was renamed Loyola University, in 1912 it began to move to the current Lake Shore Campus. To meet the growing needs of Chicago, Loyola established professional schools in law, medicine and nursing; the Chicago College of Dental Surgery became part of the university in 1923, was closed 70 years later.
A downtown campus was founded in 1914, with it the School of Sociology. As the predecessor to the School of Social Work, it enrolled Loyola's first female students, though the school would not become coeducational until 1966. Loyola Academy, a college prep high school, occupied Dumbach Hall on the Lake Shore Campus until it was relocated to north suburban Wilmette in 1957; the current Water Tower Campus opened in 1949. In 1962, Loyola opened a campus in Rome near the site of the 1960 Summer Olympics. In 1969, Loyola established the School of Education and consolidated medical programs at the Loyola University Medical Center, a hospital and health care complex located in Maywood, an immediate suburb of Chicago; the university separated from the Jesuits in 1970, today is under lay control and governed by a board of trustees. Loyola purchased neighboring Mundelein College in 1991. Major capital campaigns since the turn of the century have enhanced Loyola's academic profile and campuses. In 2005 the Loyola University Museum of Art was established on the Water Tower Campus, the Rome campus was renamed in honor of Director Emeritus John P. Felice.
In 2009, the Cuneo Foundation presented the university with the Cuneo Mansion and Gardens, a 100-acre estate with an Italianate mansion and extensive collections of art and furnishings located in suburban Vernon Hills. The $50 million gift is the largest in Loyola history. In 2010, Loyola purchased the Resurrection Retreat Center in Woodstock, which became the school's fifth campus for retreat and ecological study. In 2012, Loyola alumnus Michael R. Quinlan donated $40 million to the business school, renamed in his honor. During this time over 200,000 square-feet of LEED-certified sustainable spaces have been built on the Lake Shore Campus alone, along with significant mixed-use developments on the Water Tower Campus. Today, Loyola ranks among the top 89 universities in the nation, is in the midst of over $800 million in capital construction projects. In 2015, the university established Arrupe College, a uniquely structured two-year college designed to give low-income students access to a Loyola education.
On May 23, 2016, Loyola named Jo Ann Rooney its 24th president. She is the first female president in the history of the university. Loyola's flagship Lake Shore Campus is along the shores of Lake Michigan in the Rogers Park and Edgewater neighborhoods on the north side of Chicago, eight miles north of the Loop. Founded in 1912, it is the primary residential campus for the school, is the home of the College of Arts and Sciences, a variety of graduate programs. A collection of over forty buildings, the campus offers ample green space and lakeshore access, as well as several landmarks: The Madonna della Strada Chapel, a striking Art Deco masterpiece completed in 1939, is the center of Loyola's religious life; the Mundelein Center, a 200-foot tall Art Deco skyscraper completed in 1930, is the home of Loyola's fine and performing arts programs and a National Historical Landmark. The Joseph J. Gentile Arena, which holds 5,500 for basketball and campus events, was expanded to include the Norville Center, a student-athlete academic center and home of Rambler athletics.
One of the largest events held annually in Gentile Arena is Colossus, which features a musical artist and comedian. Artists including Jason Derulo and John Mulaney have performed for Colossus; the Halas Recreation Center was remodeled and incorp
