The Extensor hallucis longus is a thin muscle, situated between the Tibialis anterior and the Extensor digitorum longus that functions to extend the big toe, dorsiflex the foot, and assists with foot inversion.

Extensor ossis metatarsi hallucis, a small muscle, sometimes found as a slip from the Extensor hallucis longus, or from the Tibialis anterior, or from the Extensor digitorum longus, or as a distinct muscle ; it traverses the same compartment of the transverse ligament with the Extensor hallucis longus.

* Extensor hallucis longus, a tendon in the human foot.

Extensor digitorum longus arises on the lateral tibial condyle and along the fibula to be inserted on the second to fifth digits and proximally on the fifth metatarsal.

* Extensor pollicis longus

Extensor carpi radialis longus is one of the five main muscles that control movements at the wrist.

The fibres end at the upper third of the forearm in a flat tendon, which runs along the lateral border of the radius, beneath the Abductor pollicis longus and Extensor pollicis brevis ; it then passes beneath the dorsal carpal ligament, where it lies in a groove on the back of the radius common to it and the Extensor carpi radialis brevis, immediately behind the styloid process.

# REDIRECT Extensor carpi radialis longus muscle

The Extensor carpi radialis brevis is shorter and thicker than the extensor carpi radialis longus.

The longus muscle can be found above the distal end of the Extensor carpi radialis brevis.

The fibres end approximately at the middle of the forearm in the form of a flat tendon, which is closely connected with that of the extensor carpi radialis longus, and accompanies it to the wrist ; it passes beneath the Abductor pollicis longus and Extensor pollicis brevis, beneath the extensor retinaculum, beneath the dorsal carpal ligament, and inserts into the lateral dorsal surface of the base of the third metacarpal bone, with a few fibres inserting into the medial dorsal surface of the second metacarpal bone.

Under the dorsal carpal ligament the tendon lies on the back of the radius in a shallow groove called Lister's tubercle, to the ulnar side of that which lodges the tendon of the Extensor carpi radialis longus, and separated from it by a faint ridge.

It arises from the anterior surface of the fibula for about the middle two-fourths of its extent, medial to the origin of the Extensor digitorum longus ; it also arises from the interosseous membrane to a similar extent.

Occasionally united at its origin with the Extensor digitorum longus.

Extensor group: tibialis anterior originates on the proximal half of the tibia and the interosseous membrane and is inserted near the tarsometatarsal joint of the first digit.

Extensor Carpi Radialis Longus / Brevis: Both insert on the base of metacarpal II ; Assist with wrist extension and radial flexion of the wrist

Extensor Carpi Ulnaris: Inserts on the base of metacarpal V ; Extends and fixes wrist when digits are being flexed ; assists with ulnar flexion of wrist

The extensor minimi digiti ( extensor digiti quinti proprius ) is a slender muscle of the forearm, placed on the ulnar side of the Extensor digitorum communis, with which it is generally connected.

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 communis tendon on the dorsum of the first phalanx of the little finger.

But for purely definition purposes -- used in conjunction with your regular Squatting, Leg Curling, Leg Extensor programs -- a heavy weight is not needed.

* Extensor: the hallux dorsiflexes, and the other toes fan out ; this is Babinski's sign, which indicates damage to the central nervous system.

All other major extensor muscles in the superficial layer of the posterior compartment ( the Extensor Digitorum, Extensor Carpi Radialis Brevis, Extensor Carpi Ulnaris, and the Extensor Digiti Minimi ) are innervated by the posterior interosseous branch of the radial nerve.

flexor hallucis longus arises on the back of the fibula ( i. e. on the lateral side ), and its relatively thick muscle belly extends distally down to the flexor retinaculum where it passes over to the medial side to stretch across the sole to the distal phalanx of the first digit.

The plantar tendon on the front ( flexor perforans digitorum ) splits into two sections, and enters the front toes while the hind plantar ( flexor longus hallucis ) splits and enters the hind toes.

The hallux ( large toe ) is primarily flexed by the flexor hallucis longus muscle, located in the deep posterior of the lower leg, via the flexor hallucis longus tendon.

On the other side of the fascia are the tibialis posterior muscle, the flexor digitorum longus muscle, and the flexor hallucis longus muscle, along with the posterior tibial artery and posterior tibial vein and the tibial nerve.

Muscles of the big toe: abductor hallucis stretches medially along the border of the sole, from the calcaneus to the first digit.

The dorsalis pedis artery pulse can be palpated readily lateral to the extensor hallucis longus tendon ( or medially to the extensor digitorum longus tendon ) on the dorsal surface of the foot, distal to the dorsal most prominence of the navicular bone which serves as a reliable landmark for palpation.

flexor hallucis brevis arises on the medial cuneiform bone and related ligaments and tendons.

On its lower edge on either sides are its lateral and medial processes ( serving as the origins of the abductor hallucis and abductor digit minimi ).

Adductor hallucis is part of this group, though it originally formed a separate system ( see contrahens.

Additional flexion control is provided by the flexor hallucis brevis.

It is extended by the abductor hallucis muscle and the adductor hallucis muscle.

The surface of bone behind the groove is rough, for the attachment of the plantar calcaneocuboid ligament, a few fibers of the flexor hallucis brevis, and a fasciculus from the tendon of the tibialis posterior.
