Frank Henry Netter (25 April 1906 – 17 September 1991) was an American surgeon and medical illustrator.The first edition of his Atlas of Human Anatomy — his "personal Sistine Chapel" [1] — was published in 1989; he was a fellow of the New York Academy of Medicine where he was first published in 1957.
It is occupied by the extensors of the digits, the extensor digitorum communis and the extensor indicis proprius. The extensor indicis proprius usually runs and inserts onto the ulnar side of the extensor digitorum communis of the index finger. [4] The fifth compartment is occupied by the extensor digiti minimi, the extensor of the little finger.

In human anatomy, the extensor indicis (proprius) is a narrow, elongated skeletal muscle in the deep layer of the dorsal forearm, placed medial to, and parallel with, the extensor pollicis longus. Its tendon goes to the index finger , which it extends.
Netter's Essential Histology is a textbook/atlas of human histology authored by William K. Ovalle [1] [2] and Patrick C. Nahirney. [ 3 ] [ 4 ] Drawings by medical illustrator, Frank H. Netter , with contributing artwork by James A. Perkins, Joe Chovan, John A. Craig, and Carlos A.G. Machado, are in the book. [ 5 ]
Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
The radial nerve innervates the finger extensors and the thumb abductor; that is, the muscles that extend at the wrist and metacarpophalangeal joints (knuckles) and abduct and extend the thumb. The median nerve innervates the flexors of the wrist and digits, the abductors and opponens of the thumb, the first and second lumbricals. The ulnar ...
A single median band passes down the middle of the finger along the back of the proximal phalanx, inserting into the base of the middle phalanx. A band known as the retinacular ligament runs obliquely along the middle phalanx, and connects the fibrous digital sheath on the anterior side of the phalanges to the extensor expansion.
