_____ ________ are fascicles located near the outer surface of the nerve, and they innervate regions closer or more proximal to the root trunk

The 1st cranial nerve is the ______ nerve. It conveys sense of smell, and functions as a sensory nerve.

The nerve enters the skull through the foramina of the cribriform plate of the ethmoid bone.

The ______ nerve transmits sight from the retina of the eye to the brain, and functions as a sensory nerve.

The nerve enters the skull through the _____ canal of the sphenoid bone.

The ______ nerve functions to move some muscles of the eye, and is a motor nerve.

The nerve lies within the lateral wall of the cavernous sinus, and it exits through the superior orbital fissure of the sphenoid bone.

The ______ nerve functions to move the superior oblique eye muscle, and is a motor nerve.

This nerve lies within the lateral wall of the cavernous sinus, and it exits through the superior orbital fissure of the sphenoid bone.

The 5th cranial nerve is the trigeminal nerve. Select the 3 divisions of the nerve.

1. The trigeminal nerve has both motor and sensory components.

2. The motor component supplies the muscles of mastication, and the sensory component serves the teeth, tongue, and oral cavity.

This division of the trigeminal nerve supplies the upper face and scalp

1. The V2: maxillary division of the trigeminal nerve supplies the lower face.

2. 1. The V3: mandibular division of the trigeminal nerve supplies the middle face.

The ophthalmic nerve enters the skull through the:

The maxillary nerve enters the skull through the:

The mandibular nerve enters the skull through the:

The ______ nerve innervates the lateral rectus muscle. It functions to move the eye laterally, and is a motor nerve.

This nerve runs through the cavernous sinus next to the carotid artery, and it exits through the superior orbital fissure of the sphenoid bone.

The ______ nerve carries both sensory and motor components.

The nerve carries the motor component for the muscles of facial expression, posterior suprahyoid muscles, and parasympathetic innervation to salivary & lacrimal glands. The sensory component serves the taste buds, body of tongue, patch of skin behind ear.

The facial nerve leaves the cranial cavity by passing through the 1. _________ which leads to the 2. facial canal within the temporal bone, and finally exits the skull 3. _________.

The _______ nerve serves as a sensory nerve for hearing and balance. This nerve conveys signals from the inner ear to the brain.

The nerve enters the cranial cavity through the internal acoustic meatus (IAM) of the temporal bone.

The _______ nerve carries an efferent component for the pharyngeal & stylopharyngeus muscles & parotid gland.

In addition, the nerve also carries an afferent component for taste and sensation of posterior 1/3 of tongue & gag reflex.

The following structures: muscles of soft palate and pharynx, taste posterior 1/3 of tongue, parotid gland, and skin around the ear are innervated by the _______ nerve.

The glossopharyngeal nerve passes through the skull by way of the:

The ______ nerve carries a large somatic efferent component for the muscles of the soft palate, pharynx, larynx, and a large autonomic (parasympathetic) component to organs in the thorax and abdomen.

The nerve carries a smaller somatic afferent component for a small amount of skin around the ear and for taste sensation for the epiglottis.

The vagus nerve travels in a carotid sheath along with the:

The _____ nerve functions as an efferent nerve and has 2 roots: a cranial root and spinal root.

The spinal root supplies the trapezius and SCM. The cranial root supplies muscles of the soft palate and larynx.

The ______ nerve functions as a efferent nerve for both the intrinsic and extrinsic muscles of the tongue.

There is a relay in the ganglion on both sides of spinal cord for the ________ nervous system.

1. Preganglionic neurons= arise from CNS and supply ganglia

2. Postganglionic neurons= arise from ganglia and supply the tissues
