All cells in the body have similar structures. All of them have a cellular semipermeable membrane, cytoplasm, and organelles. Most cells, and all nerve cells, have nuclei, which is the plural of nucleus. All nerve cells, or neurons have one single nucleus, including cranial nerves. The job of the nucleus is to be the control center, and in the case of neurons, they decide when an impulse should be sent down along its axon.

Nuclei of cranial nerves V VI and VII are found in the?
Pons.
The is a conduction pathway between higher and lower brain centers and houses nuclei for cranial nerves V-VII?
pons
What do cranial nerves VII IX and X contain?
Cranial nerves VII, IX and X are called mixed nerves because they contain both motor and sensory nerves.
How do somatic sensory nerve impulses get to the brainstem from the head itself?
Somatic sensory nerve impulses from the head travel through the cranial nerves, such as the trigeminal nerve (V), facial nerve (VII), and glossopharyngeal nerve (IX). These nerves carry sensory information to the brainstem, specifically to the trigeminal nerve nuclei, which process and relay the information to higher brain regions for further processing and perception.
Taste buds are monitored by cranial nerves?
Yes, taste buds are monitored by three cranial nerves: the facial nerve (VII) for the front two-thirds of the tongue, the glossopharyngeal nerve (IX) for the back one-third of the tongue, and the vagus nerve (X) for the throat and epiglottis. These nerves transmit taste information from the taste buds to the brain.
Which cranial nerve's carry gustatory information?
Brances of the Facial (VII), Glossopharyngeal (IX), and Vagus (X) cranial nerves carry information about taste
Which cranial nerve is involved in the secretion of saliva?
CN VII (facial) The cranial nerves that regulate salivation are CN VII (facial) and CN IX (Glossopharyngeal). The cranial nerves that transmit the special sense of taste are CN VII (facial, to the anterior 2/3rd of the tongue) and CN X (vagus, to the posterior 1/3rd of the tongue). Of these nerves, only CN VII (facial) transmits both taste and salivation control.
Does the nerve going to the eyebrow go to the 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.
Which nerves innervate the taste buds?
Brances of the Facial (VII), Glossopharyngeal (IX), and Vagus (X) cranial nerves carry information about taste
How many cranial nerves carry both sensory and motor impulses?
Five cranial nerves are mixed or sensorimotor nerves:Trigeminal Nerve (V)Facial Nerve (VII)Glossopharyngeal Nerve (IX)Vagus Nerve (X)Accessory Nerve (XI)
The Parasympathetic nerve is found in what cranial nerve?
The parasympathetic nerve is found in cranial nerves III, VII, IX, and X. Each of these cranial nerves carries parasympathetic fibers that regulate various involuntary functions in the body.
What is nerve that contains filbers that both send and receive messages is called?
It is called a Mixed Nerve Example- all spinal nerves, and cranial nerves V, VII, IX, X.
