The brain communicates directly with structures like the eyes, ears, face, tongue, and muscles in the head and neck via the cranial nerves. These nerves are responsible for controlling various functions such as vision, hearing, taste, and facial expressions.

Nerves that leave the brain directly are called?
Cranial nerves
Why are cranial nerves known as cranial neveres not branial nerves?
Cranial nerves are named as such because they arise directly from the brain (cranium) rather than from the spinal cord. The term "cranial" is used to refer to structures within or connected to the skull, while "branial" is not a recognized term in anatomy.
What nerves are involved in diplopia?
The cranial nerves involved in diplopia are the third (oculomotor), fourth (trochlear), and sixth (abducens) cranial nerves, which control eye movement and coordination. Issues with these nerves can result in misalignment of the eyes, leading to double vision.
Is true Both spinal and cranial nerves have dorsal and ventral roots?
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
What cranial nerve passes through the foramen magnum?
The vagus nerve (CN X) passes through the foramen magnum. It is the 10th cranial nerve and plays a crucial role in controlling various organs in the body, including the heart and digestive system.
Nerves that leave the brain directly are called?
Cranial nerves
What is the total number of cranial nerves?
There are 12 pairs of cranial nerves, which make a total of 24 cranial nerves. These nerves emerge directly from the brain and are responsible for various sensory, motor, and autonomic functions in the head and neck.

What number is cranial nerves related directly to the oral cavity?
Five and seven
Where the cranial nerves belong?
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.
How many cranial nerves are?
How many cranial nerves are there
Which nerves go through openings in the skull and stimulate the head and neck?
cranial nerves.
How many cranial nerves does a rat have?
Rats have 12 pairs of cranial nerves.
Are Cranial nerves paired?
yes! there are 12 pairs of cranial nerves
Pure sensory cranial nerve?
Cranial nerves are primarily sensory. These nerves are directly between the brain and the brainstem and are responsible for smell, vision, eye movement, facial sensation, and the tongue movement.
How many pairs are of the cranial nerves?
There are 12 pairs of cranial nerves that are part of the PNS. These nerves are sensory, mixed and mostly motor.
What is the difference between peripheral nerves and cranial nerves?
Peripheral nerves are nerves that extend from the spinal cord to various parts of the body, while cranial nerves are nerves that emerge directly from the brain and primarily innervate the head and neck. Cranial nerves are named numerically based on their location or function, while peripheral nerves are named based on the region or structure they innervate.
