Muscles Of The Hand Photograph by Asklepios Medical Atlas Biology Diagrams 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 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.
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.
Hand Anatomy: Bones, muscles, arteries and nerves Biology Diagrams
Learn about the intrinsic and extrinsic muscles of the hand, their attachments, actions and innervation. See 3D models, dissection images and diagrams of the thenar, hypothenar, lumbricals and interossei muscles. 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 bones, joints, ligaments, muscles, and nerves of the human hand, an extraordinary part of the upper limb. See detailed diagrams and descriptions of the hand's anatomy and how it works. Learn about the 11 intrinsic and 15 extrinsic muscles in each hand that help with thumb, finger, and palm movements. See the muscle origin, insertion, action, and innervation for each muscle group. 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
