Anatomy of the arm

In this VR lesson, Evan guides you through the arm model dissected in ten layers, highlighting key anatomical pathways and structures. Starting superficially, he points out cutaneous nerves and veins in the skin and adipose tissue, along with deep muscular fascia and anterior forearm muscles. Deeper layers reveal the biceps brachii, medial epicondyle, and reflected muscles like the flexor carpi ulnaris, exposing the ulnar nerve, artery, vein, and deeper forearm muscles such as the flexor digitorum superficialis.

Evan then explores the hand’s anatomy, detailing tendons, thenar and hypothenar muscles, lumbricals, adductor pollicis, and palmar interosseous muscles. Posterior views showcase the extensor compartment muscles in situ.

He traces nerve pathways throughout, from the brachial, median, ulnar, and radial nerves in the arm, through the cubital fossa and carpal tunnel, into the hand. Evan highlights branching patterns, including the posterior and anterior interosseous nerves. Vascular pathways follow the brachial artery and vein as they branch into radial and ulnar arteries, culminating in the superficial palmar arch where these arteries anastomose. Evan’s detailed walkthrough offers an invaluable overview of the integrated anatomy of muscles, nerves, and vessels from the upper arm to the hand.
