what does ninth cranial nerve control? glossopharyngeal nerve is a mixed nerve, it has sensory and motor part. the sensory is at the poserior 1/3 of the tongue. It also is part of the pharyngeal plexus. (9,10,11)
The motor part of the nerve ONLY supply the stylopharyngeus muscle!
The accessory nerve is also known as cranial nerve XI. It is primarily responsible for innervating the sternocleidomastoid and trapezius muscles, facilitating shoulder elevation and head rotation. The nerve has both cranial and spinal components, with its cranial part originating from the brainstem and the spinal part arising from the upper cervical spinal cord.
The trochlear nerve (cranial nerve IV) is the only cranial nerve that emerges from the posterior aspect of the brainstem and decussates, forming a chiasmal pattern. It is responsible for the motor function of the superior oblique muscle of the eye.
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
Smell impulses are carried by the cranial nerve called the olfactory nerve (cranial nerve I). It is responsible for transmitting information about odors from the nose to the brain.
The second cranial nerve is the optic nerve.
Spinal Accessory Nerve
The sternocleidomastoid and trapezius muscles are controlled by the accessory cranial nerve. Some call it cranial nerve XI.
The accessory nerve is also known as cranial nerve XI. It is primarily responsible for innervating the sternocleidomastoid and trapezius muscles, facilitating shoulder elevation and head rotation. The nerve has both cranial and spinal components, with its cranial part originating from the brainstem and the spinal part arising from the upper cervical spinal cord.
There are 31 pairs of spinal nerves which originate in the spinal cord. There are twelve cranial nerves, which are referred to by Roman numerals. Ten of the twelve cranial nerves originate from the brainstem; the other two stem from the forebrain and thalamus. The nerve that is responsible for eyebrow movement is the VII cranial nerve, also known as the facial nerve. This is one of the ten cranial nerves originating from the brainstem.
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
Spinal nerve.....
The spinal accessory nerve (cranial nerve XI) is involved in hyperextending and flexing the neck. This nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in these movements.
The trochlear nerve (cranial nerve IV) is the only cranial nerve that emerges from the posterior aspect of the brainstem and decussates, forming a chiasmal pattern. It is responsible for the motor function of the superior oblique muscle of the eye.
The spinal accessory nerve, or cranial nerve XI (eleven), is a purely motor nerve which innervates the trapezius and sternocleidomastoid muscles. The sternocleidomastoid muscles are used to turn the head. The Accessory nerve also provides somatic motor fibers to muscles of the soft palate, pharynx, and larynx (spinal and medullary fibers respectively.)
