Posterior compartment of the forearm. Extensor digitorum; Extensor digiti minimi (little finger only) Extensor indicis (index finger only) of phalanges, at interphalangeal joints [4] Lumbricals of the hand; Dorsal interossei of the hand; Palmar interossei; of thumb [5] Extensor pollicis brevis (proximal phalange) Extensor pollicis longus ...
The supinator and the anconeus are the two extensor muscles in the posterior compartment of the forearm that do not pass through wrist extensor compartments. [3] The first compartment locating the most radial is occupied by the extensor pollicis brevis and the abductor pollicis longus to insert to the thumb.
The mobile wad (or mobile wad of Henry) is a group of the following three muscles found in the lateral compartment of the forearm: [1] brachioradialis; extensor carpi radialis brevis; extensor carpi radialis longus; It is also sometimes known as the "wad of three", [2] "lateral compartment", [3] or "radial group" [4] of the forearm.
The first compartment is the site where entrapment tendinitis, better known as De Quervain's disease, occurs. Repetitive trauma is believed to cause thickening of the tendons, which lead to movement restriction of the tendons through the compartment. Any movement of the thumb and wrist causes the patient pain, inflammation and swelling.
Dorsiflexion of the foot: The muscles involved include those of the Anterior compartment of leg, specifically tibialis anterior muscle, extensor hallucis longus muscle, extensor digitorum longus muscle, and peroneus tertius. The range of motion for dorsiflexion indicated in the literature varies from 12.2 [8] to 18 [9] degrees. [10]
An extensor expansion (extensor hood, [1] dorsal expansion, dorsal hood, dorsal aponeurosis [citation needed]) is the special connective attachments by which the extensor tendons insert into the phalanges. These flattened tendons (aponeurosis) of extensor muscles span the proximal and middle phalanges. [2]
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 ...
Knee pain is thought to be primarily associated with specific quadriceps muscle weakness or fatigue, especially in the vastus medialis obliquus (VMO).It is known that fatigue can be caused by many different mechanisms, ranging from the accumulation of metabolites within muscle fibers to the generation of an inadequate motor command in the motor cortex.
