Many of the muscles that move the fingers and thumb originate in the forearm. Areas of the human hand include.
The red lines show where the tendons attach the muscles to the bones.
Palm of hand anatomy. Wrinkles the skin of the hypothenar eminence and deepens the curvature of the hand improving grip. The main tendons of the hand are. All small carpal bones join the bones lying next to them and thus make the anatomy of the human hand very complex.
The front or palm side of the hand is referred to as the palmar side. Each hand consists of 19 bones. Extensor tendons of the fingers which attach to the middle and distal phalanges and extend.
The important structures of the hand can be divided into several categories. The image below shows the bones of the hand from the back side. The palm comprises the underside of the human hand.
The muscles in the forearm and palm thenar muscles all work together to keep the wrist and hand moving stable and well aligned. The opisthenar area dorsal is the corresponding area on the posterior part of the hand. The palm includes five metacarpals and each finger except the thumb contains one proximal phalanx one middle phalanx and one distal phalanx.
The heel of the hand is the area anteriorly to the bases of the metacarpal bones. Superficialis tendons which pass through the palm side of the wrist and hand. Palmar aponeurosis is composed of very dense connective tissue that extends out into each of the fingers.
Also known as the broad palm or metacarpus it consists of the area between the five phalanges finger bones and the carpus wrist joint. A thickening of the deep fascia covering the palm of the hand. The back of the hand is called the dorsal side.
Profundus tendons which pass through the palm side of the wrist and hand. All five metacarpals together are recognized as the metacarpus. Originates from the palmar aponeurosis and flexor retinaculum attaches to the dermis of the skin on the medial margin of the hand.
Wrist palm and fingers are thus made up of several small joints. Other muscles in the palm attachments. The bones in the fingers and thumb are known as phalanges.
The palm volar which is the central region of the anterior part of the hand. Located in the palm are 17 of the 34 muscles that articulate the fingers and thumb and are connected to the hand skeleton through a series of tendons.
