Human Hand Muscles Anatomy Medical Illustration3d Stock Illustration Biology Diagrams Learn about the structure and function of your hand and wrist, including the 19 bones, 34 muscles, nerves, tendons and ligaments that make them work. Find out how to care for your hand and wrist health and what conditions can affect them.
Learn about the hand muscles, their attachment, nerve supply and action. The hand muscles are divided into extrinsic and intrinsic groups, and include thenar, hypothenar, lumbrical and interossei muscles. Learn about the anatomy and function of the muscles of the hand, which are divided into extrinsic and intrinsic groups. The extrinsic muscles are located on the forearm and the intrinsic muscles are located within the hand itself.
Hand muscles : Attachment, Nerve Supply & Action Biology Diagrams
The skeletal muscles of the hand are responsible for the movement of the hand and fingers.[1] These muscles subdivide into two groups: the extrinsic and intrinsic muscles.[2][3] The extrinsic muscle group is called so because the muscle belly originates in the forearm.[2][4] The intrinsic muscle groups consist of smaller muscles solely located within the various hand osseofascial compartments
The Hand Anatomy is complex and important to understand, it consists of 27 bones, 27 joints, 34 muscles and a lot of ligaments that connects joints together. To understand the complex hand anatomy, we will divide this article into: bones anatomy, joints anatomy, muscles and ligaments anatomy. Bony Hand Anatomy Metacarpals Bones The thenar muscles, which form the bulge of muscles evident at the base of the thumb, are essential to the hand's flexibility and gripping ability. One of these muscles, the opponens pollicis, moves the thumb across the hand to oppose the other fingers, allowing us to pinch a small object between the thumb and finger to pick it up.
