Nerves · Whole bodyMedial reticulospinal tractTractus reticulospinalis medialis tractusA descending pathway from the reticular formation of the pons to the spinal cord, running in the anterior funiculus and driving the antigravity muscles.
Nerves · Lower limbMedial sural cutaneous nerveNervus cutaneus medialis suraeA cutaneous branch of the tibial nerve that descends between the heads of gastrocnemius and joins a fibular branch to form the sural nerve.
Nerves · Whole bodyMedial vestibulospinal tractTractus vestibulospinalis medialisA short descending pathway from the medial vestibular nucleus to the cervical spinal cord that steadies the head and links head and eye movements.
Nerves · Upper limbMedian nerveNervus medianusA major nerve of the upper limb, formed by roots from two plexus cords, that reaches the hand by the carpal tunnel.
Nerves · HeadMeningeal branch of maxillary nerveRamus meningeus nervi maxillarisA small branch of the maxillary nerve, given off inside the skull, that supplies the dura mater of the front of the middle cranial fossa.
Nerves · HeadMental nerveNervus mentalisA sensory branch of the inferior alveolar nerve that leaves the jaw through the mental foramen to supply the chin and lower lip.
Nerves · Upper limbMiddle trunk of brachial plexusTruncus medius plexus brachialisThe middle trunk of the brachial plexus, the direct continuation of the C7 ventral ramus between the scalene muscles.
Nerves · HeadMotor nucleus of facial nerveNucleus nervi facialisThe cluster of motor neurons in the lower pons whose axons form the facial nerve's motor root and move the face.
Nerves · HeadMotor root of trigeminal nerveRadix motoria nervi trigeminiThe small motor root of the trigeminal nerve, leaving the side of the pons and joining the mandibular nerve to supply the chewing muscles.
Nerves · Upper limbMuscular branches of axillary nerveRami musculares nervi axillarisThe motor branches of the axillary nerve, given behind the surgical neck of the humerus to the deltoid and teres minor.
Nerves · Lower limbMuscular branches of deep fibular nerveRami musculares nervi fibularis profundiThe motor twigs of the deep fibular nerve to the extensor muscles of the anterior leg and the short extensors on the foot.
Nerves · Upper limbMuscular branches of median nerveRami musculares nervi medianiThe motor branches of the median nerve, supplying most flexor muscles of the forearm and the thenar muscles of the hand.
Nerves · Upper limbMuscular branches of radial nerveRami musculares nervi radialisThe motor branches the radial nerve gives in the arm and at the elbow to triceps, anconeus, brachioradialis and the long radial wrist extensor.
Nerves · Upper limbMuscular branches of ulnar nerveRami musculares nervi ulnarisThe branches the ulnar nerve gives near the elbow to flexor carpi ulnaris and the ulnar half of flexor digitorum profundus.
Nerves · Upper limbMusculocutaneous nerveNervus musculocutaneusA nerve from the brachial plexus's lateral cord that supplies the front muscles of the arm and the skin of the lateral forearm.
Nerves · HeadNerve to mylohyoid muscleNervus mylohyoideusA small motor branch of the inferior alveolar nerve that supplies mylohyoid and the anterior belly of digastric.
Nerves · Lower limbNerve to piriformis muscleNervus musculi piriformisA short branch of the sacral plexus that enters piriformis from its pelvic surface, usually carrying fibres of the first and second sacral nerves.
Nerves · Lower limbNerve to quadratus femoris muscleNervus musculi quadrati femorisA branch of the sacral plexus that supplies quadratus femoris and inferior gemellus and sends a twig to the hip joint.
Nerves · HeadNucleus of abducens nerveNucleus nervi abducentisA motor nucleus in the lower pons beneath the fourth ventricle that drives the lateral rectus and coordinates sideways gaze of both eyes.
Nerves · HeadNucleus of accessory nerveNucleus nervi accessoriiA column of motor neurons in the upper cervical spinal cord whose axons form the accessory nerve to sternocleidomastoid and trapezius.
Nerves · HeadNucleus of hypoglossal nerveNucleus nervi hypoglossiA column of motor neurons near the midline of the medulla, under the fourth ventricle, whose axons form the hypoglossal nerve to the tongue.
Nerves · HeadNucleus of oculomotor nerveNucleus nervi oculomotoriusThe main motor nucleus of the third cranial nerve, a paired cell column in the upper midbrain that moves most eye muscles.
Nerves · HeadNucleus of trochlear nerveNucleus nervi trochlearisA small motor nucleus in the lower midbrain whose axons cross and leave the back of the brainstem as the trochlear nerve to superior oblique.
Nerves · Lower limbObturator nerveNervus obturatoriusA lumbar plexus nerve that runs along the side wall of the pelvis and through the obturator canal to the adductor muscles of the thigh.
