The action is extension, that is why it is called the "extensor"
The extensor digitorum longus muscle has a parallel fascicle arrangement where muscle fibers run parallel to the long axis of the muscle. This arrangement allows the muscle to generate a strong pulling force to extend the toes.
Flipping someone the bird primarily involves the contraction of two muscles: the flexor digitorum profundus and the flexor digitorum superficialis, which control the movement of the middle finger.
Some of the muscles present in cats but not in humans include the panniculus carnosus, a thin sheet of muscle beneath the skin that allows cats to move their skin independently of their muscles, aiding in grooming and hunting. Cats also have a specialized muscle called the tensor tympani, which helps dampen loud noises by adjusting tension in the eardrum.
In decerebrate posturing (extensor) rigidity, all four limbs are extended and the hands are pronated. In decorticate (flexor) rigidity, the arms, wrists, and fingers are flexed.
A human's legs and cat's back legs are different due to different movements each make and how they are structured. In a cat, the lower rear leg anterior has a tibialis anterior muscle. In a human, anterior has tibialis interior and extensor digitorum longus muscle.
Extensor digitorum longus, extensor hallucis longus and extensor digitorum brevis
Extensor digitorum longus (lateral 4 toes), Extensor digitorum brevis (medial 4 toes) and extensor hallucis longus (big toe only)
The extensor digitorum communis is an extensor of the wrist and fingers. The extensor digitorum communis is the primary extensor of the lateral four fingers IP joint and assists in wrist extension.
Extensor digiti minimi, extensor digitorum longus, and extensor hallucis.
extensor hallicus longus
extensor digitorum, extensor indicis, extensor digiti minimi, flexor digitorum superficialis, and the flexor digitorum profundus. There are also extrinsic muscles that work only in the thumb; these include the flexor pollicis longus, extensor pollicis longus, extensor pollicis brevis, and adbuctor pollicis longus
extensor digitorum
The bulk of the muscle is proximal. But part of it isn't.
This isn't a joint; it's a muscle. But if you were wondering what joints are involved with the extensor digitorum longus, they are the PIP joint and talonavicular joint.
The muscles that produce extension of the finger joints and wrist are the extensor muscles. In the forearm, the specific extensor muscles responsible for extension of the fingers and wrist include the extensor digitorum and extensor carpi radialis muscles.
