Thumb anatomy bones. This connects to the thumbs distal phalanx which is also the tip of the digit. This latter bone articulates with the distal phalanx at the interphalangeal joint. The thumb connects with a bone in the hand first metacarpal.

Unlike fingers the thumb does not possess an intermediate phalanx bone. Shaped like a crescent moon. Following are the carpal bones in the first row starting from the lateral side same side as your thumb right next to the radius and working across.

This bone has an odd shape that allows the thumb to move in multiple directions yet it stabilizes thumb as well. The thumb also differs in having much freedom of movement and being opposable to tips of other digits. Shaped like a little boat.

This first metacarpal connects to the proximal phalanx. Nerves of the fingers. The finger bones are known as phalanges singular phalanx.

A joint is formed when two bones meet and articulate which allows movement. The second bone proximal phalange extends from the knuckle to the base of the thumb. Ligaments connect finger bones and help keep them in place.

And fingers move by the pull of forearm muscles on the tendons. Thumb arthritis is the second most common type of arthritis in the hand. Has a scaphoid tubercle.

The trapezium is a saddle shaped bone in the second row of wrist bones and it is the main place where the thumb metacarpal connects to the wrist. The skeleton of the thumb consists of the first metacarpal bone which articulates proximally with the carpus at the carpometacarpal joint and distally with the proximal phalanx at the metacarpophalangeal joint. Osteoarthritis or degenerative arthritis is a process that occurs with aging and describes the deterioration of the joint cartilage.

Picture of finger anatomy. Fingers are constructed of ligaments strong supportive tissue connecting bone to bone tendons attachment tissue from muscle to bone and three phalanges bones. The thumb has two of each.

The most prevalent hand arthritis involves the last joint in each finger. It differs from other digits in having only two phalanges tubular bones of the fingers and toes. Fingers have a complex anatomy.

Finger movement is controlled by muscles in the forearms that pull on finger tendons. Anatomically the thumb is compromised of the metacarpal connected to the trapezium a carpal bone in the wrist. Thumb also called pollex short thick first digit of the human hand and of the lower primate hand and foot.

There are two interphalangeal joints ip joints on each finger. Joints are lined with smooth cartilage that allows for the easy movement of one bone relative to another. Each finger has 3 phalanges bones and 3 hinged joints.

Shaped like a pyramid. Anatomy of the fingers finger bones. Tendons connect muscles to bones.

There are no muscles in the fingers. The thumb has two bones. The first bone distal phalange extends from the tip of the thumb to the knuckle.
