| nervus statoacusticus | <anatomy, nerve> The vestibulocochlear nerve is responsible for the sense of hearing and balance (body position sense). Lesions of the eighth nerve can result in deafness, tinnitus, dizziness, vertigo and vomiting. Synonym: cranial nerve VIII. (27 Sep 1997) |
|---|---|
| nervus subclavius | <anatomy, nerve> A branch from the superior trunk of the brachial plexus supplying the subclavius muscle. Synonym: nervus subclavius. (05 Mar 2000) |
| nervus subcostalis | <anatomy, nerve> The ventral ramus of the twelfth thoracic nerve; it courses below the last rib, supplies parts of the abdominal muscles and gives off cutaneous branches to the skin of the lower-most ventrolateral abdominal wall and to the superolateral gluteal region. Synonym: nervus subcostalis. (05 Mar 2000) |
| nervus sublingualis | <anatomy, nerve> A branch of the lingual to the sublingual gland and mucous membrane of the floor of the mouth. Synonym: nervus sublingualis. (05 Mar 2000) |
| nervus suboccipitalis | Dorsal ramus of the first cervical nerve, passing through the suboccipital triangle and sending branches to the rectus capitis posterior major and minor, obliquus capitis superior and inferior, rectus capitis lateralis, and semispinalis capitis; the first cervical spinal nerve is generally considered to have only motor fibres, but the suboccipital nerve receives sensory fibres for proprioception via a communicating branch from the second cervical spinal nerve. Synonym: nervus suboccipitalis. (05 Mar 2000) |
| nervus supraclavicularis intermedius | <anatomy, nerve> One of several nerves arising from the C-3-C-4 part of the cervical plexus which run across the top of the shoulder and pass down across the clavicle to supply the skin of the top of the shoulder and in the infraclavicular region. Synonym: nervus supraclavicularis intermedius, middle supraclavicular nerve. (05 Mar 2000) |
| nervus supraclavicularis lateralis | <anatomy, nerve> One of several branches of the C-3-C-4 portion of the cervical plexus which descend to the skin over the acromion and deltoid region. Synonym: nervus supraclavicularis lateralis, posterior supraclavicular nerve. (05 Mar 2000) |
| nervus supraclavicularis medialis | <anatomy, nerve> One of several nerves arising from the cervical plexus which supply the skin over the upper medial part of the thorax. Synonym: nervus supraclavicularis medialis, anterior supraclavicular nerve. (05 Mar 2000) |
| nervus supraorbitalis | <anatomy, nerve> A branch of the frontal nerve leaving the orbit through the supraorbital foramen or notch and dividing into branches distributed to the forehead and scalp, upper eyelid, and frontal sinus. Synonym: nervus supraorbitalis. (05 Mar 2000) |
| nervus suprascapularis | <anatomy, nerve> Arises from the upper trunk of the brachial plexus (fifth and sixth cervical spinal nerves), passes downward parallel to the cords of the brachial plexus, then through the scapular notch, supplying the supraspinatus and infraspinatus muscles, and also sending branches to the shoulder joint. It is vulnerable to injury in fractures of the middle 1/3 of the clavicle; a lesion of the suprascapular nerve results in a loss of lateral rotation at the shoulder so that when relaxed the limb rotates medially (waiter's tip position); ability to initiate abduction is also affected. Synonym: nervus suprascapularis. (05 Mar 2000) |
| nervus supratrochlearis | <anatomy, nerve> A branch of the frontal nerve supplying the medial part of the upper eyelid, the central part of the skin of the forehead, and the root of the nose. Synonym: nervus supratrochlearis. (05 Mar 2000) |
| nervus suralis | <anatomy, nerve> A branch of the tibial nerve which supplies sensory innervation to parts of the lower leg and foot. (12 Dec 1998) |
| nervus tensoris tympani | <anatomy> A branch of the mandibular nerve conveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor tympani muscle. Synonym: nervus tensoris tympani. (05 Mar 2000) |
| nervus tensoris veli palatini | <anatomy> A branch of the mandibular nerveconveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor veli palatini muscle. Synonym: nervus tensoris veli palatini. (05 Mar 2000) |
| nervus tentorii | <anatomy, nerve> The tentorial branch, a branch arising in a recurrent fashion from the intracranial portion of the ophthalmic nerve supplying the tentorium and supratentorial falx cerebri. Synonym: ramus tentorii, nervus tentorii. (05 Mar 2000) |
