Adductor pollicis muscle

The video tutorial discusses the adductor pollicis muscle, part of the thinner musculature in the hand. It covers the muscle's origin, insertion, innervation, and function. The adductor pollicis has two heads, transverse and oblique, originating from different carpal bones and attaching to the thumb. It is innervated by the deep branch of the ulnar nerve and functions to adduct the thumb. The video also highlights additional learning resources available through Kenhub.
