Tendons are fibrous cords, similar to a rope, and are made of collagen. They have blood vessels and cells to maintain tendon health and repair injured tendon. Tendons are attached to muscles and to bone. As the muscle contracts it pulls on the tendon and the tendon moves the bone to which it is attached as well as any joints it crosses. Jump to:

2024年3月9日 · Hand anatomy consists of bones, muscles, and neurovascular structures that work together. They help us touch, hold, and move objects every day. While intrinsic hand muscles of hand anatomy play a role, forearm muscles also send tendons through the wrist, allowing for a wide range of movements.

2020年6月7日 · The long flexor tendons of the fingers arise from the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) forearm muscles. These tendons enter the hand via the carpal tunnel, enclosed in a common synovial sheath.

2023年11月13日 · The other major contributors are actually the forearm muscles, which project tendons towards the hand via an equally complex and flexible anatomical structure, called the wrist. A solid understanding of the hand requires good grasp (pun intended) of its entire anatomy, so in this page we will look at all of the above structures.

There is articular cartilage essentially everywhere that two bony surfaces move against one another, or articulate. Ligaments and Tendons. Ligaments are tough bands of tissue that connect bones together. Two important structures, called collateral ligaments, are found on either side of each finger and thumb joint.

2021年6月29日 · Tendons are white, flexible rope-like cords at the ends of muscles that attach muscles to bone. When muscles contract, they pull on the tendons to move the bones. The tendons that run down our fingers are held in place by a series of ligaments, called pulleys, that form stable arches over tendons, forming a “tunnel-like” sheath.

2016年3月5日 · The hand, with the carpus, is the most complex collection of interconnected joints in the human body, and a large assembly of tendons carries out its extensive range of motion. Distinctive groups of muscles execute the actions of these tendons on the hand.

2023年8月14日 · Six long flexor muscles originate in the forearm but have tendon attachments in the hand. The six muscles are the flex carpal radialis muscle, the flexor carpal ulnaris muscle, the flexor pollicis longus muscle, the flexor digitorum profundus muscle, the flexor digitorum superficialis muscle, and the palmaris longus muscle.

The finger section provides detailed descriptions of the extrinsic and intrinsic tendons of the finger along with a diagram of the flexor pulley system. In addition, hand sections with information on the fascial structures (retention ligaments), the wrist, joint cartilage, potential spaces of the hand and osteology are included.
