You are speaking of the 12 cranial nerves:
I. Olfactory nerve which branches out of the telencephalon
II. Optic which branches out of the diencephalon
III. Oculomotor nerve which branches out of the mesencephalon
IV. Trochlear nerve nerve which branches out of the mesencephalon
V. Trigeminal nerve which branches out of the pons
VI. Abducens nerve which branches out of the pons
VII. Facial nerve which branches out of the pons
VIII. Vestibulochochlear nerve which branches out of the pons
IX. Glossopharangeal nerve nerve which branches out of the medulla
X. Vagus nerve nerve which branches out of the medulla
XI. Accessory nerve nerve which branches out of the medulla & cervical spine
XII. Hypoglossal nerve nerve which branches out of the medulla
What else can I help you with?
What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck and are considered part of the peripheral nervous sytem?
These are 12 pairs of nerves called the cranial nerves.
How many pairs of nerves leave the central nervous system?
There are 31 pairs of nerves that leave the central nervous system - 12 pairs of cranial nerves that exit from the brain and 31 pairs of spinal nerves that exit from the spinal cord.
What nerve is cranial and spinal?
The basic difference between the cranial nerves and the spinal nerves is the role they play, in helping our bodies to function properly. The body has what is called a peripheral nervous system consisting of more than 100 billion nerve cells, which run all throughout our body, making connections with our brain, as well as other parts of the body, and sometimes with each other. The peripheral nervous system is composed of two systems the somatic and autonomic nervous system. These nerves connect with both the brain and the spinal cord. Our muscles are controlled by voluntary and sensory receptors in the skin, this is an example of the somatic system. The autonomic system connects the brain stem and the spinal cord to the internal organs, and also regulates the body processes, like heart rate and blood pressure, stomach acid, and the speed of food travelling through our digestive systems. The autonomic nervous system is divided into sympathetic and parasympathetic divisions. Each has a job to do within the body. The sympathetic division helps us to deal with stressful or emergency situations. They help us to know, when to fight and when to take flight. The parasympathetic division helps the body to function, in normal situations. Both divisions regulate our pulse, breathing and blood pressure to keep them stable. The cranial nerves connect our brain to our eyes, ears, nose, throat and other parts of our head, neck and trunk. There are twelve (12) pairs of cranial nerves. The nerves, which connect the spinal cord to with other parts of the body are called spinal nerves. The brain communicates or connects with other parts of the body through the spinal nerves. We have thirty-one (31) pairs of spinal nerves. Spinal nerves and cranial nerves are connected with the somatic and the autonomic parts of the peripheral nervous system. Some nerves are sensory nerves and other nerves are motor nerves, depending upon their function within the body.
How many pairs of cranial nerves present in shark fishes?
Sharks have 12 pairs of cranial nerves. These nerves are responsible for functions such as vision, smell, and movement in sharks.
What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck?
The nerves that originate in the brain and carry messages to and from structures in the head and neck are known as cranial nerves. There are 12 pairs of cranial nerves, each with specific functions related to sensory and motor control in the head and neck region. These nerves play crucial roles in activities such as vision, hearing, taste, and facial movements.
How many pairs of spinal cord nerves connect the brain to the peripheral nervous system?
31
What includes 12 pair of cranial nerves that extend from the brain and 31 pairs of spinal nerves extending from the spinal cord?
Peripheral nervous system
What are the spinal and cranial nerves ganglia?
Peripheral Nervous System (PNS) original answer by btbchris
compare the central and the peripheral nervous system?
The Central nervous system includes the brain and spinal cord.The brain is the control center for all activities in the body.It is made of billions of neurons. The spinal cord is made up of bundles of neurons.Sensory neurons send impulse to the brain.All the nerves outside CNS ( Central Nervous System) that connects the brain and spinal cord to other body parts are part of the Peripheral nervous system. The Peripheral nervous system includes 12 pairs of nerves from your brain called cranial nerves, and 31 pairs of nerves from your spinal cord called Spinal nerves.
What name refers to nerves that only originate in the brain carry messages to and from structures in the head and neck and are considered part of the peripheral nervous sytem?
These are 12 pairs of nerves called the cranial nerves.
The peripheral nervous system is composed of how many pairs of spinal nerves?
31
What are there 43 pairs of in the peripheral nerveous system?
In the peripheral nervous system, there are 43 pairs of nerves, which include 12 pairs of cranial nerves and 31 pairs of spinal nerves. These nerves are responsible for transmitting sensory and motor information between the central nervous system and the rest of the body. Each pair serves specific functions, innervating various regions and organs, facilitating communication throughout the body.
What are the 12 pairs of nerves that exit the brain as part of the peripheral nervous system?
The 12 pairs of nerves that exit the brain are the cranial nerves. (CN I) Olfactory, (CNII) Optic, (CN III) Oculomotor, (CN IV) Trochlear, (CN V) Trigeminal, (CN VI) Abducent, (CN VII) Facial, (CN VIII) Vestibulocochlear, (CN IX) Trigeminal, (CN X) Vagus, (CN XI) Hypoglossal, (CN XII) Hypoglossal Nerves
What structure passes through each intervertebral foramen?
A spinal nerve passes through each intervertebral foramen. These nerves exit the spinal cord and branch out to various parts of the body to facilitate communication between the brain and the rest of the body.
How many cranial nerves?
nerves emerging from brain are called cranial nerves.they are 12 pairs
How many pairs of nerves leave the central nervous system?
There are 31 pairs of nerves that leave the central nervous system - 12 pairs of cranial nerves that exit from the brain and 31 pairs of spinal nerves that exit from the spinal cord.
What are the peripheral neuron pairs?
Peripheral neurons are bundled together to make up the 31 pairs of peripheral nerve roots. Each pair of nerves is named for the vertebra from which it exits. These are known as: C1-8. T1-12. L1-5. S1-5. Coccygeal
