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.

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.

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 originates medially on the fibula and is inserted on the first digit.

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.

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.

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.

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.

* Extensor digitorum brevis, a muscle on the upper surface of the foot

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.

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

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

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

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.

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

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

Neuroimaging identifies the anterior insula and anterior cingulate as key areas in the brain determining whether people conform in their preferences in regard to its being popular with their peer group.

The cilia on the body are in dikinetids, in which either the anterior one or both kinetosomes may be ciliated, and which are associated with fibers composed of overlapping postciliary microtubules, called postciliodesmata and found only in this group and the closely related Karyorelictea.

The cells have two heterokont flagella, inserted parallel to one another at the anterior, whose ultrastructure is a distinguishing characteristic of the group.

However, they do not have the grooved articulation and high frequencies of other sibilants, and most phoneticians continue to group them together with bilabial, and ( inter ) dental, as non-sibilant anterior fricatives.

A damaged anterior cruciate ligament in his right knee, sustained in the first minute of the group match against Sweden at the 2006 World Cup, kept Owen out of regular football for nearly a year, until April 2007.

Neuroimaging identifies the anterior insula and anterior cingulate as key areas in the brain determining whether people prefer something in regard to its being popular with their peer group.

* The anterior interosseous branch courses with the anterior interosseous artery and innervates all the muscles of the deep group of the anterior compartment of the forearm except the medial ( ulnar ) half of flexor digitorum profundus and flexor carpi ulnaris muscle.

# the dilator muscle group — which includes the dilator naris muscle that expands the nostrils ; it is in two parts: ( i ) the dilator nasi anterior muscle, and ( ii ) the dilator nasi posterior muscle.

Prototheria, on the other hand, was generally recognised as a subclass until quite recently, on the basis of an hypothesis which defined the group by two supposed synapomorphies: ( 1 ) formation of the side wall of the braincase from a bone called the anterior lamina, contrasting with the alisphenoid in therians ; and ( 2 ) a linear alignment of molar cusps, contrasting with a triangular arrangement in therians.

Damage to the dorsomedial nucleus or anterior group of the thalamus ( limbic-specific nuclei ) is also associated with this disorder.

( 2004 ) studied metabolic rate of glucose in anterior and posterior cingulate gyrus in patients with schizophrenia, schizotypal personality disorder ( SPD ) and compared them with a control group.

( 2007 ) did an experiment in which they correlated the size of anterior cingulate gyrus in schizophrenic patients with their functioning on social cognition, psychopathology and emotions with control group.

The anterior cingulate gyrus was found to be bilaterally smaller in patients with schizophrenia as compared with control group.

Spinal muscular atrophies are a genetically and clinically heterogeneous group of rare debilitating disorders characterised by degeneration of lower motor neurons – that is, neuronal cells situated in the anterior horn of spinal cord – and subsequent atrophy ( wasting ) of various muscle groups in the body.

Below the cerebral cortex, the precuneus is connected with the dorsalmost nuclei of the thalamus, including the ventral lateral nucleus, the central and anterior nuclei of the intralaminar nuclear group, and the lateral pulvinar.

We identified a cell group within the medial preoptic area / anterior hypothalamus of age-matched adult sheep that was significantly larger in adult rams than in ewes ...

The infrahyoid muscles are a group of four pairs of muscles in the anterior part of the neck.

The anterior group consists of two nuclei, an antero-medial and an antero-lateral.

Onuf ’ s nucleus is a distinct group of neurons located in the ventral part ( laminae IX ) of the anterior horn of the sacral region of the human spinal cord involved in the maintenance of micturition and defecatory continence, as well as muscular contraction during orgasm.
