This forearm muscle is responsible for extending all of the fingers. The palmar interossei pull our fingers together.

Anatomy 101 Wrist Muscles And Forearm Muscles The

The muscles of the hand can be broken down into three main regions.

Muscle anatomy hand. In part 3 ill show you a drawing process for drawing hands from reference or from your imagination. Extrinsic and intrinsic muscles. Muscles of the hand.

The muscles that originate in the forearm and insert onto the hand are responsible for power grip and the muscles that originate in the hand and are responsible for position grip are the intrinsic muscles. This is a slender triangle shaped tendon a fibrous band. The muscles of the hand consist of five groups.

The intrinsic muscles of the hand are located within the hand itself. The extrinsic muscles are located in the anterior and posterior compartments of the forearm. They are responsible for the fine motor functions of the hand.

Hand muscles interossei dorsal and palmar the interossei muscles begin between the bones of the hand. Part 1 is about the muscles of the hand and how they should inform your drawings. There are four dorsal and three palmar interossei muscles.

While all interossei bend the mcp joints the dorsal interossei allow us to spread our fingers away from each other. Some of the muscles tendons and ligaments of the hand as well as those of the forearm that affect hand movement include. This is a tutorial on those muscles.

The thenar lateral or thumb side of the palm hypothenar medial or little finger side of the palm and intermediate middle of the hand muscles. Muscles acting on the hand can be divided into two groups. They control crude movements and produce a forceful grip.

The intrinsic muscles of the hand are those muscles that are responsible for position grip. Then ill teach you how to draw the surface details of the hands like fingernails skin folds and fat pads.
