These include the adductor pollicis palmaris brevis interossei lumbricals thenar and hypothenar muscles.

Muscles in the hand. The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers the muscles of the hand can be subdivided into two groups. The extrinsic muscle groups are the long flexors and extensors they are called extrinsic because the muscle belly is located on the forearm the intrinsic group are the smaller muscles located. The intrinsic muscles of the hand are those muscles that are responsible for position grip.

The palmar interossei pull our fingers together. The muscles of the hand are responsible for the hand and fingers movement. Some make broad smooth movements and others make small finite movements.

They are termed extrinsic muscles because the muscle belly is positioned on the forearm. Hand muscles interossei dorsal and palmar the interossei muscles begin between the bones of the hand. It s the combination of the exterior and deep muscles of the hand and forearm that allow.

The hand has several muscles. This is a tutorial on the intrinsic muscles of the hand. The extrinsic and intrinsic muscle groups.

The extrinsic muscles and the intrinsic muscle groups. They are responsible for the fine motor functions of the hand. The muscles of the hand are redivided into two groups.

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. While all interossei bend the mcp joints the dorsal interossei allow us to spread our fingers away from each other. The extrinsic groups are the long flexors and extensors muscles.

In this article we shall be looking at the anatomy of the intrinsic muscles of the hand.
