Trigeminal Nerve (Cranial Nerve V) The trigeminal nerve or cranial nerve V contains sensory from the gasserian ganglion and motor fibers. This nerve has three major branches or divisions, the ophthalmic (V1), maxillary (V2), and mandibular (V3), which supply the eye, deep and superficial structures of the face, and the cranium. The motor component is located in the mandibular division and it supplies mainly the muscles of mastication.

How long does it take to get results from a culture and sensitivity test? to be considered totally negative, blood cultures take 5 days, CSF 2-3 days, and urine in 24hrs. obviously they only do a sensitivity if they grow an organism. it basically depends on the site where they obtain the specimen that determines how long they attempt to grow it.

Background Cranial nerve XI, the spinal accessory nerve (SAN), is vulnerable to injury, owing to its long and superficial course in the posterior cervical neck.An important landmark in the neck, the SAN is considered to contribute most motor innervation to the trapezius muscle.

The Facial Nerve (CN VII) Within the parotid gland, the facial nerve terminates by bifurcating into five motor branches. These innervate the muscles of facial expression: 1  Temporal branch – Innervates the frontalis, orbicularis oculi and corrugator supercilii. 2  Zygomatic branch – Innervates the orbicularis oculi.

Spinal nerves The motor branch directed to the deep muscles of the neck and the muscles beneath it the hyoid bone, as well as innervate the sternocleidomastoid and trapezius muscles. Mixed branch of cervical plexus is the phrenic nerve (n. phrenicus). Motor fibers are sent to the phrenic nerve to the diaphragm, and sensitive innervate the pleura and pericardium. Brachial plexus (plexus brachialis) formed branches of the lower four cervical nerves and the anterior branch of the 1st thoracic nerve.

- The superior branch of the superior gluteal nerve innervates the gluteus medius and sometimes provides innervation to the gluteus minimus. The superior gluteal nerve passes across the deep aspect of the gluteus medius at approximately 5 cm superior to the tip of the greater trochanter (Jacobs and Buxton, 1989).

Hypoglossal nerve Hypoglossal nerve. (Redirected from Lingual branches of hypoglossal nerve) The hypoglossal nerve is the twelfth cranial nerve, and innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus which is innervated by the vagus nerve. It is a nerve with solely a motor function.

Areas Innervated by the Hypoglossal Nerve Most of the tongue's muscles are innervated by the hypoglossal nerve. These include both extrinsic muscles, which originate on a bone outside the tongue, and intrinsic muscles, which have both ends within the tongue.he areas innervated by the hypoglossal nerve consist of almost all the muscles of the tongue. Find out the details of the hypoglossal nerve's function. slide 1 of 5. The hypoglossal nerve is the twelfth and final cranial nerve (XII).

The Muscles of Mastication Fig 1.1 – The temporalis muscle. The temporalis muscle originates from the temporal fossa – a shallow depression on the lateral aspect of the skull. The muscle is covered by tough fascia, this can harvested surgically, and used to repair a perforated tympanic membrane (an operation known as a myringoplasty).he entirety of the muscle lies superficially to the pterygoids and temporalis, covering them. 1  Attachments: The superficial part originates from maxillary process of the zygomatic bone. 2  Actions: Elevates the mandible, closing the mouth. 3  Innervation: Mandibular nerve (V 3).

Vagus Nerve Anatomy Gross Anatomy. The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body. It contains somatic and visceral afferent fibers, as well as general and special visceral efferent fibers.(See Table 1, below.).he right nerve branches from the vagus at the root of the neck around the right subclavian artery. It courses superiorly in the tracheoesophageal groove to enter the larynx between the cricopharyngeus and the esophagus.

Temporalis Muscle: Action, Innervation & Origin Temporalis Muscle: Action. The temporalis muscle functions to move the mandible, which is the official term for the lower jaw. Specifically, the movements of the lower jaw caused by the temporalis muscle include: Elevation ; Retraction ; Side-to-side ; Based on these movements, the temporalis muscle plays a large role in biting and chewing food.

Facial Nerve It arises from the pons region of the brainstem, posterior to the abducens nerve (CN VI) and anterior to the vestibulocochlear nerve (CN VIII). The facial nerve travels from the pons through the facial canal in the temporal bone to exit the skull at the stylomastoid foramen. As the facial nerve passes through the temporal bone, several smaller nerves branch off from the main nerve, including the greater (superficial) petrosal nerve and the chorda tympani.
