Cranial nerves serve areas in the...cranium. Areas such as the eyes, mouth, and ears, and muscles of the face. The only exception to this rule is the Vagus nerve which serves heart, lungs, and the digestive system. List of 12 nerves and general area for functioning: I Olfactory:nose II Optic: eyes III Occulomotor: eyes IV Trochlear: eye V Trigeminal: sensory areas around center of face VI Abducens: eye VII Facial: salivary glands, muscles of face VIII Vestibulocochlear: ear IX Glossopharyngeal: throat X Vagus: heart, lungs, digestion XI Accessory: trapezius, sternonucleiod muscle XII Hypoglossal: tongue

To which structures do the 12 cranial nerves connect in the human body?
The 12 cranial nerves connect to various structures in the human body, including the brain, head, neck, and some internal organs.
What part of the nervous system consists of all of the spinal nerves and cranial nerves is the?
The peripheral nervous system consists of all the spinal nerves and cranial nerves. These nerves connect the central nervous system (brain and spinal cord) to the rest of the body, allowing for communication and control of bodily functions.
What are the functions of the 31 pairs of spinal nerves in the human body"?
The 31 pairs of spinal nerves in the human body have several functions, including transmitting sensory information from the body to the brain, controlling muscle movements, and regulating autonomic functions such as heart rate and digestion.
How are the 31 pairs of spinal nerves distributed throughout the human body and what functions do they serve?
The 31 pairs of spinal nerves are distributed throughout the human body, with each pair connected to a specific region of the body. These nerves serve important functions such as transmitting sensory information from the body to the brain and controlling muscle movements.
Where do nerves originate in the human body?
Nerves originate in the human body from the brain and spinal cord, which make up the central nervous system, and extend throughout the body to transmit signals and control various functions.

Where are neurons found in the human body apart from the brain and spinal cord?
In the nerves of the peripheral nervous system; 12 cranial nerves and 31 spinal nerves.
What part of the nervous system consists of all of the spinal nerves and cranial nerves is the?
The peripheral nervous system consists of all the spinal nerves and cranial nerves. These nerves connect the central nervous system (brain and spinal cord) to the rest of the body, allowing for communication and control of bodily functions.
How do the functions of the two groups of peripheral groups differ?
the spinal nerves "receives" the nerve impulses from the rest of the body while the cranial nerves "process" these nerve impulses.

The 31 pairs of spinal nerves in the human body have several functions, including transmitting sensory information from the body to the brain, controlling muscle movements, and regulating autonomic functions such as heart rate and digestion.
What are name of the nerves that found in the nervous system?
There are different types of nerves in the human body namely: the cranial nerves, the spinal nerves, the sympathetic nerves, and the encephalon nerves just but to mention a few. Examples of these nerves includes: the optic nerve, the facial nerve, the vagus nerve, the thoracic nerve, and accessory nerve.
How many nerve endings in the entire body?
There are approximately seven trillion nerves in the human body. There are twelve pairs of cranial nerves and thirty two pairs of spinal nerve roots which then branch out to the rest of the body.
what consists the peripheral nervous system?
-cranial nerves: which are located on the brain and carry impulses to the head and neck -spinal nerves: which extend from the spine and provide information to areas of the body below the neck -autonomile nerves: which responsible for involuntary body functions such as breathing and digestion

What are two major components of the parasympathetic division of the ANS?
Two major components of the parasympathetic division of the autonomic nervous system are the cranial nerves, specifically the vagus nerve (cranial nerve X), which innervates many organs in the body, and sacral nerves originating from the sacral region of the spinal cord, which also play a key role in controlling various bodily functions, such as digestion and elimination.
Where do nerves originate in the human body?
Nerves originate in the human body from the brain and spinal cord, which make up the central nervous system, and extend throughout the body to transmit signals and control various functions.
How much nerves are there in the human body?
