| nervus ciliaris longus | <anatomy, nerve> One of two or three branches of the nasociliary nerve, which by-pass the ciliary ganglion, supplying post-synaptic sympathetic fibres for the dilator pupillae muscle and sensory fibres for the ciliary muscles, iris, and cornea. Synonym: nervus ciliaris longus. (05 Mar 2000) |
| nervus thoracicus longus | <anatomy, nerve> Arises from the fifth, sixth, and seventh cervical nerves (roots of brachial plexus), descends the neck behind the brachial plexus, and is distributed to the serratus anterior muscle; it is somewhat unusual in that it courses on the superficial aspect of the muscle is supplies; its paralysis results in "winged scapula". Synonym: nervus thoracicus longus, Bell's respiratory nerve, external respiratory nerve of Bell, posterior thoracic nerve. (05 Mar 2000) |
| tendon sheath of flexor digitorum longus muscle of foot | The synovial sheath that envelops the flexor digitorum longus tendons as they pass into the foot deep to the flexor retinaculum. Synonym: vagina tendinum musculi flexoris digitorum pedis longi. (05 Mar 2000) |
| tendon sheath of flexor hallucis longus muscle | <anatomy> The synovial sheath that envelops the tendon of the flexor hallucis longus as it passes into the foot deep to the flexor retinaculum. Synonym: vagina tendinis musculi flexoris hallucis longi. (05 Mar 2000) |
| flexor digitorum longus | <anatomy, muscle> Origin, middle third of posterior surface of tibia; insertion, by four tendons, perforating those of the flexor brevis, into bases of distal phalanges of four lateral toes; action, flexes second to fifth toes; nerve supply, tibial nerve. Synonym: musculus flexor digitorum longus, long flexor muscle of toes, musculus flexor longus digitorum. (05 Mar 2000) |
| flexor hallucis longus | <anatomy, muscle> Origin, lower two-thirds of posterior surface of fibula; insertion, base of distal phalanx of great toe; action, flexes great toe; nerve supply, medial plantar. Synonym: musculus flexor hallucis longus, long flexor muscle of great toe, musculus flexor longus hallucis. (05 Mar 2000) |
| longus capitis | <anatomy, muscle> Origin, anterior tubercles of transverse processes of third to sixth cervical vertebrae; insertion, basilar process of occipital bone; action, twists or flexes neck anteriorly; nerve supply, cervical plexus. Synonym: musculus longus capitis, long muscle of head, musculus rectus capitis anticus major. (05 Mar 2000) |
| longus colli muscle | <anatomy> Medial part: origin, the bodies of the third thoracic to the fifth cervical vertebrae; insertion, the bodies of the second to fourth cervical vertebrae; superolateral part: origin, the anterior tubercles of the transverse processes of the third to fifth cervical vertebrae; insertion, the anterior tubercle of the atlas; inferolateral part: origin, the bodies of the first to third thoracic vertebrae; insertion, the anterior tubercles of the transverse processes of the fifth and sixth cervical vertebrae; action, for all three parts, twist neck and flex neck anteriorly; nerve supply, for all three parts, ventral primary rami of cervical spinal nerves (cervical plexus). Synonym: musculus longus colli, long muscle of neck. (05 Mar 2000) |
| bursa of extensor carpi radialis brevis muscle | <anatomy> The bursa between the tendon of the extensor carpi radialis brevis and the base of the third metacarpal. Synonym: bursa musculi extensoris carpi radialis brevis. (05 Mar 2000) |
| paradoxical extensor reflex | <clinical sign> Extension of the great toe and abduction of the other toes instead of the normal flexion reflex to plantar stimulation, considered indicative of pyramidal tract involvement ("positive" Babinski). Synonym: Babinski reflex, Babinski's phenomenon, great-toe reflex, paradoxical extensor reflex, toe phenomenon. (05 Mar 2000) |
