We have twelve cranial nerves as part of the peripheral nervous system. Though they exit the cranium and are mostly associated with senses and functions of the head, they have far reaching affects, all the way down into the abdominal organs. They are as follows:
I. Olfactory
II. Optic
III. Oculomotor
IV. Trochlear
V. Trigeminal
VI. Abducens
VII. Facial
VIII. Vestibulocochlear
IX. Glossopharyngeal
X. Vagus
XI. Spinal Accessory
XII. Hypoglossal
It is the Vagus nerve that has the farthest reaching affects, including the heat, lungs, and gastrointestinal system.
Most of the cranial nerves originate from the brainstem.
The cranial nerves exit from the brainstem. They emerge from specific openings in the skull called foramina, which are small bony passageways. These openings provide a pathway for the cranial nerves to exit the skull and innervate different parts of the head and neck.
Each eye has one nerve for vision, the optic nerve, Cranial Nerve II. Nerves are actually bundles of many nerve fibers. There are nerves that supply impulses for the muscles associated with the eyeballs so they can move are the Cranial Nerve III, Oculomotor, Cranial Nerve IV, Trochlear, and Cranial Nerve VI, the Abducens nerve.
There are 12 pairs of cranial nerves, each with specific functions related to sensory, motor, or mixed functions in the head and neck regions.
cranial nerves are nerves which arise from different parts of brain that are paired and 12 pair and 24 in number. peripheral nerves are neurons that exists out side brain and spinalcord and make up peripheral nerve system.
How many cranial nerves are there
Rats have twelve pairs of cranial nerves.
There are 12 pairs of cranial nerves that are part of the PNS. These nerves are sensory, mixed and mostly motor.
The number of cranial nerves that a cat have is 12. The cranial nerves are mostly located at the cats brain.
nerves emerging from brain are called cranial nerves.they are 12 pairs
Cranial Nerves 1-2 Cranial Nerves 3-4 belong to the midbrain. Cranial Nerves 5-8 belong to the pons. Cranial Nerves 9-12 belong to the hindbrain.
