Tendons are fibrous strands that look like rope and are made of collagen. They have blood vessels and cells to maintain tendon health and repair damaged tendons. Tendons are attached to muscles and bones.
Tendons are fibrous strands that look like rope and are made of collagen. They have blood vessels and cells to maintain tendon health and repair damaged tendons. Tendons are attached to muscles and bones. When the muscle contracts, it pulls on the tendon, and the tendon moves the bone it's attached to and any joints it crosses.

Flexor digitorum profundus (FDP) sener
Flexor digitorum profundus (FDP) senerFDP tendons help flex the index, middle, ring, and little finger at the fingertip joint. The muscle that moves these tendons is a common muscle belly that all fingers share. The muscle belly divides into 4 tendons. They run down the forearm and into the carpal tunnel. The four tendons slide in sheaths along the hand and fingers and insert into the fingertip bones. These tendons run closer to the bone than the other flexors of the hand and fingers. learn more aboutFlexor tendon injuries.
Sener des Flexor digitorum superficialis (FDS).
FDS tendons help flex the index, middle, ring, and pinky fingers at the middle finger joint. They are powered by a common muscle belly that is common to all fingers and divides into four tendons. They travel through the forearm and into the carpal tunnel. These tendons, like the flexor digitorum profundus tendons, slide in sheaths along the fingers and hand. At the level of the fingers, each tendon divides into two separate strands and then inserts into the middle bone of the finger on either side of the flexor digitorum profundus tendon that runs further down the finger.

Extensor Digitorum Tendons (EDC).
Extensor Digitorum Tendons (EDC).EDC tendons extend the index, middle, ring, and pinky fingers. All fingers share a common muscle belly. The tendons run down the forearm through a tight band of tissue at the top of the wrist. The band of tissue, or retinaculum, holds the tendons in place but allows them to slide up and down the arm. The four tendons then run along the back of the hand and on each finger. In the finger, the ends of other tendons that start in the hand join with them to move the fingers. Together, these combined tendons straighten the fingers at the three finger joints.
Extensor Digital Minimi (EDM) sene
EDM raises the little finger. It works with the extensor digitorum communis of the little finger. The muscle belly is located in the forearm. The tendon passes through a tight ligament or retinaculum at the wrist and then into the hand. The band of tissue, or retinaculum, holds the tendons in place but allows them to slide up and down the arm. It works with other tendons that attach at the back or back of the finger to stretch the three small finger joints. Less than 50% of people are born with this tendon.
Sene des Extensor Index Proper (EIP).
The EIP tendon straightens the index finger. It works with the extensor digitorum communis of the index finger. It has its own muscle belly in the forearm and, while turning into a tendon, moves through a fixed ligament or retinaculum in the wrist. The band of tissue, or retinaculum, holds the tendons in place but allows them to slide up and down the arm. It moves along the hand and attaches to the back of the index finger to straighten the three index finger joints.
tendons of the thumb
Elderly des Abductor pollicis longus (APL).
Elderly des Abductor pollicis longus (APL).The APL tendon runs on the radial side of the wrist (the side where the thumb is located). Its muscle belly is located in the forearm and then travels across the wrist in a tight band called the retinaculum. The band of tissue, or retinaculum, holds the tendons in place but allows them to slide up and down the arm. It attaches to the metacarpal bone of the thumb and helps pull the thumb away from the rest of the hand. This tendon, along with the extensor brevis tendon, can become inflamed and painful. The name for the inflammation of these two tendons isde Quervains-Syndrom.
Flexor pollicis longus (FPL) Elderly
The FPL tendon flexes the thumb. It is unique to humans. It starts as a muscle in the forearm and then moves through the carpal tunnel as a tendon in the wrist. It is then covered by a tunnel or sheath and inserted into the most distal (farthest from your body) bone in the thumb.
Extensor pollicis longus (EPL) sen
EPL straightens the most distal (farthest from your body) joint of the thumb. Its muscle belly is in the forearm, and the tendon runs along the wrist and enters the third compartment of the ligament, which holds the tendons in place at the wrist. It then moves around a protruding part of the radius bone that acts like a pulley. It is called Lister's tubercle. The tendon then attaches to the most distal bone of the thumb.
Extensor Thumb Brevis (EPB) sen
The EPB tendon, along with the APL, also takes the thumb off your hand. The EPB tendon is located in the forearm and then runs along the radial side of the wrist. This tendon also moves in the first compartment of the ligament that holds the tendons in place at the wrist. It's lit in the conditional callde Quervains-Syndrom.
wrist tendons
Flexor carpi radialis (FCR) sen
Flexor carpi radialis (FCR) senThe FCR tendon is one of two tendons that flex the wrist. Its muscle belly is located in the forearm and then runs along the inside of the forearm and crosses the wrist. It attaches to the base of the second and third bones of the hand. It is also attached to one of the carpal bones, the trapezium.
Flexor carpi ulnaris (FCU) Elderly
The FCU tendon is one of two tendons that flex the wrist. His muscle belly is in his forearm. The tendon runs down the inside of the forearm on the pinky side and crosses the wrist. It attaches to the carpal bone, the pisiform bone and also the 5th carpal bone.
Palmaris longus sene
The palmaris longus tendon is a very low function tendon in the hand. About a quarter of the population does not have this tendon. The rest have different sizes of this tendon. His muscle belly is in his forearm. It migrates into the wrist and connects to the fascia of the palm. This tendon is often used to repair other tendons.
Extensor carpi radialis brevis (ECRB) sen
Extensor carpi radialis brevis (ECRB) senThe ECRB tendon is one of three tendons, including the ECRL and ECU, that work together to bend the wrist backwards. Its muscle belly is located in the forearm and then travels to the thumb side of the wrist on the back of the forearm. Along with the ECRL, it attaches to the base of the hand bones. It is shorter and thicker than the ECRL.
Extensor carpi radialis longus (ECRL) sene
The ECRL tendon works with the ECRB and ECU to flex the wrist backwards. ECRL and ECRB also help flex the wrist toward the thumb. His muscle belly is in his forearm. It is thinner and longer than the ECRB. It runs along the back of the forearm and attaches to the base of the hand bones.
Extensor carpi ulnaris (ECU) sen
The ECU tendon works with the ECRL and ECRB to extend the wrist. It differs from these other two tendons in that it moves the wrist toward the little finger. His muscle belly is in his forearm. The tendon runs along the back of the forearm, through a groove in the ulna, and attaches to the base of the hand bones.

Biceps are old
Biceps are oldThe biceps muscle has tendons at each end of the muscle. At the shoulder, both tendons are attached to the large flat bone in the upper body, the shoulder blade. The muscle belly then runs through the entire upper arm and divides into two tendons. One tendon attaches to the forearm bone, the radius, and the other spreads out and connects to the fascia along the upper part of the forearm. The tendons have two functions: they bend the elbow and rotate the palm toward the sky.
triceps year
The triceps tendon is wider than most other upper extremity tendons. Its muscle belly is on the back of the upper arm. There are three muscle bellies that together make up this tendon. It forms a tendon near the elbow and attaches to the most bony, prominent side of the posterior elbow. The tendon stretches the elbow.
Oberarmsenil
The brachialis tendon works with the biceps and brachioradialis to flex the elbow. The muscle belly is located in the upper arm and forms a thick tendon that attaches to the inside of the elbow. Its only function is to flex the elbow.
Brachioradialis sene
The brachioradialis tendon flexes the elbow just like the brachialis and biceps. Unlike these others, the muscle belly is mostly located in the upper part of the forearm and the tendon inserts at the wrist. In addition to bending the elbow, it can also support the rotation of the wrist. (See image in Wrist Tendons)
Supinator sene
Supinator seneThe supinator tendon is the origin of this short, broad muscle. The tendon attaches to the humerus just near the elbow. The muscle then continues its attachment to the radius. The main action is to rotate the hand
