Human Hand Skeletal Structure Depicting Finger Bones Joints

Human Hand Skeletal Structure Depicting Finger Bones Joints The features of the human palm are shown in fig. 2. the skeletal structure of the palm is the metacarpus, composed of five bones, the metacarpals, connecting the palm to the wrist on one side, and. Each human hand contains 27 bones, adding up to a total of 54 bones. these skeletal components, in conjunction with the muscles and ligaments in the area, provide framework to the human hand and enable all the mobility and agility of the hands and fingers. the hand comprises three main categories of bones, categorized based on their location.

Skeletal Diagram Of Hand Carpal bones (proximal) – a set of eight irregularly shaped bones. they are located in the area of the wrist. metacarpals – a set of five bones, each one related to a digit. they are located in the area of the palm. phalanges (distal) – the bones of the digits. the thumb has two phalanges, whilst the rest of the fingers have three. Triquetrum. pisiform. trapezium. trapezoid. capitate. hamate. together, these bones connect the lower arm to the hand and fingers as the proximal carpal bones articulate with the radius and ulna to form the wrist joint. these bones articulate with each other, allowing wrist movement so we can perform common daily activities with our hands. Phalanges: the individual bones that make up the segments of your fingers and thumb. sesamoids: small bones embedded in your tendons that help them move smoothly. wrist bones. your wrist is a complex joint made of eight bones that are arranged into two rows. the proximal row (on the back of your hand, closest to your forearm) includes the. Capitate: the largest of the wrist bones, this rests between the trapezoid and the hamate behind the middle and ring fingers. hamate: this small bone has a hook on the palmar side. it rests next.
