The Flexor digiti minimi brevis (Flexor brevis minimi digiti, Flexor digiti quinti brevis) lies under the metatarsal bone on the little toe, and resembles one of the Interossei.
The name of this muscle is Latin for the 'short flexor of the little finger'. Note that brevis is usually included to differentiate it from a longus muscle of the same name. The flexor digiti minimi longus, however, is not found in the typical human, but instead is a rare anatomical variation.
The hypothenar eminence is the mound located at the base of the fifth digit (little finger). The eminences at either side of the hand are made up of muscles. The muscles located in the thenar eminence function primarily to control the thumb.
The lateral plantar nerve is an important motor nerve in the foot because it innervates all intrinsic muscles in the sole, except for the muscles supplied by the medial plantar nerve (abductor hallucis, flexor digitorum brevis, flexor hallucis brevis, and first lumbrical).
Left: To strengthen arch muscles, place a towel on the floor, grab the towel with your toes and pull it toward you. Top: While sitting, grasp your toes and gently pull them toward you until you feel a stretch in the arch of your foot. Right: Stand as shown, with your back leg straight and heel down.
The abductor hallucis muscle is an intrinsic muscle of the foot. It participates in the abduction and flexion of the great toe.
Background: Baxter's neuropathy is a nerve entrapment syndrome that results from the compression of the inferior calcaneal nerve. The causes of Baxter's neuropathy include altered foot biomechanics such as flatfoot, plantar calcaneal enthesophytes, and plantar fasciitis.
The quadratus plantae is a muscle in the foot that extends from the anterior (front) of the calcaneus (heel bone) to the tendons of the digitorum longus muscle in the leg. It assists the flexor digitorum longus with toe flexing.
The lumbricals of the foot flex the metatarsophalangeal joints and extend the interphalangeal joints.
The Flexor hallucis brevis is a muscle of the foot that flexes the big toe.
Quadratus plantae is directly nourished from a branch of the posterior tibial artery. No distal anastomoses between the medial and lateral plantar arteries were identified, except 1 specimen in which the medial plantar artery made anastomosis with the deep plantar arch.
Flexor digitorum longus muscle
a combining form meaning “finger”: digitinervate. [comb.
Digit, in anatomy, finger or toe of land vertebrates, the skeleton of which consists of small bones called phalanges. The tips of the digits are usually protected by keratinous structures, such as claws, nails, or hoofs, which may also be used for defense or manipulation.
Extensor Digiti Minimi
| Origin | Lateral epicondyle of humerus |
|---|
| Insertion | Extensor expansion of 5th digit |
| Action | Extends 5th digit at metacarpophalangeal and interphalangeal joints |
| Innervation | Posterior interosseous nerve (C7 and C8), the continuation of the deep branch of the radial nerve (C7, C8) |
Its tendon runs through a compartment of the dorsal carpal ligament behind the distal radio-ulnar joint, then divides into two as it crosses the hand, and finally joins the expansion of the Extensor digitorum tendon on the dorsum of the first phalanx of the little finger.
In human anatomy, the extensor carpi ulnaris is a skeletal muscle located on the ulnar side of the forearm. It acts to extend and adduct at the carpus/wrist from anatomical position. Being an extensor muscle, extensor carpi ulnaris is on the posterior side of the forearm.
The extensor digiti minimi is a two joint muscle. It acts as an extensor in both joints. It extends the wrist, which means it moves the back of the hand toward the back of the forearm. It also extends the little finger, which means it straightens the little finger from a fist.
a Latin word meaning "small," used in medical names and descriptions: The abductor minimi digiti muscle moves the little finger. SMART Vocabulary: related words and phrases. Substances & structures in the body. abductor.
Description. The extensor digitorum communis is a superficial extensor muscle located in the posterior compartment of the forearm. It shares a common synovial tendon sheaths along with other extensor muscles which helps to reduce friction between the tendon and the surrounding structures.
The extensor expansions (also known as the extensor hood or dorsal digital expansion)? are triangular aponeuroses by which the extensor tendons insert onto the phalanges.
