2. Muscles of the hand - Wikipedia

   en.wikipedia.org/wiki/Muscles_of_the_hand

   The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers. The muscles of the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups. The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm ...

3. Juncturae tendinum - Wikipedia

   en.wikipedia.org/wiki/Juncturae_tendinum

   Juncturae tendinum are narrow bands of connective tissues that extend between the tendons of the extensor digitorum communis and the extensor digiti minimi. [1] [2] It is classified into three distinct types (Type 1, 2 and 3) depending on morphology. [3] Type 1: This is a thin and filamentous juncturae tendinum. Its shape can either be square ...

4. Extrinsic extensor muscles of the hand - Wikipedia

   en.wikipedia.org/wiki/Extrinsic_extensor_muscles...

   The ED divides into four tendons which, with the EI tendons, go through the fourth tendon compartment of the dorsal carpal ligament. On the back of the hand, the ED tendons diverge to follow the fingers and the EI tendon joins the ulnar side of one of the ED tendons along the back of the index finger.

5. Extensor tendon compartments of the wrist - Wikipedia

   en.wikipedia.org/wiki/Extensor_tendon...

   The extensor tendons are held in place by the extensor retinaculum. As the tendons travel over the posterior (back) aspect of the wrist they are enclosed within synovial tendon sheaths . These sheaths reduce the friction to the extensor tendons as they traverse the compartments that are formed by the attachments of the extensor retinaculum to ...

6. Extensor digitorum muscle - Wikipedia

   en.wikipedia.org/wiki/Extensor_digitorum_muscle

   The tendon to the index finger is accompanied by the tendon of extensor indicis, which lies on its ulnar side. On the back of the hand, the tendons to the middle, ring, and little fingers are connected by two obliquely placed bands, one from the third tendon passing inferior and laterally to the second tendon, and the other passing from the ...

7. Muscles of the thumb - Wikipedia

   en.wikipedia.org/wiki/Muscles_of_the_thumb

   Passing through the first tendon compartment, it inserts to the base of the first metacarpal bone. A part of the tendon reaches the trapezium, while another fuses with the tendons of the extensor pollicis brevis and the abductor pollicis brevis. Except for abducting the hand, it flexes the hand towards the palm and abducts it radially.

8. Extensor digiti minimi muscle - Wikipedia

   en.wikipedia.org/wiki/Extensor_digiti_minimi_muscle

   Its tendon passes through a compartment of the extensor retinaculum, posterior to distal radio-ulnar joint, then divides into two as it crosses the dorsum of the hand, and finally joins the extensor digitorum tendon. All three tendons attach to the dorsal digital expansion of the fifth digit (little finger).

9. Abductor digiti minimi muscle of the hand - Wikipedia

   en.wikipedia.org/wiki/Abductor_digiti_minimi...

   The abductor digiti minimi is the most variable hypothenar muscle, [4] and might be joined by accessory slips from the tendon of the flexor carpi ulnaris, the flexor retinaculum, the fascia of the distal forearm, or the tendon of the palmaris longus. Occasionally, the muscle is partially inserted onto the fifth metacarpal bone. [5]
