sensory nerve
The cranial nerves have various functions related to sensory, motor, or both. Some cranial nerves are primarily sensory, transmitting information from the senses like taste, smell, and vision to the brain. Others are mainly motor, controlling movements of the face, head, and neck muscles. Some cranial nerves have both sensory and motor functions, allowing for a combination of sensory input and motor control.
There are 12 pairs of cranial nerves that are part of the PNS. These nerves are sensory, mixed and mostly motor.
Cranial nerves III (oculomotor), IV (trochlear), VI (abducens), XI (accessory), and XII (hypoglossal) are motor nerves only.
Cranial nerves VII, IX and X are called mixed nerves because they contain both motor and sensory nerves.
Olfactory
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 12 structures receive and send sensory and motor signals between the body and brain
There are 12 pairs of cranial nerves, each with specific functions related to sensory, motor, or mixed functions in the head and neck regions.
Sensory nerves are the nerves that allow people to experience taste, touch, smell, sight, and hearing. For sight, there are photoreceptors; for hearing, there is stereocilia; for touch, there are motor neurons, and for smell there are olfactory sensory nerves.
The Optical nerver or the Second Cranial nerve controls and relays information absorbed through the rods and cones of the eye. Eye movements (eye muscles), however, are controlled by several other cranial nerves including the Oculomotor, Abducens, and Trochlear nerves.
The trigeminal nerve (cranial nerve V) is a mixed cranial nerve that contains both sensory and motor fibers. It is responsible for sensation in the face and motor functions such as biting and chewing. The sensory component detects touch, pain, and temperature from the face, while the motor component innervates the muscles of mastication. Other mixed cranial nerves include the facial nerve (VII), glossopharyngeal nerve (IX), and vagus nerve (X).
