Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), in contrast to spinal nerves (which emerge from segments of the spinal cord). 10 of the cranial nerves originate in the brainstem. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck.
We know that there are 12 pairs of cranial nerves which originate from the brain and brainstem. Remembering the names of these cranial nerves is easily mastered but it is difficult to remember their type ie whether they are Sensory nerves, motor nerves or mixed nerves.

Cranial nerves are those nerves which arise from the brain and brain stem rather than the spinal cord. Nerves arising from the spinal cord are the spinal nerves. There are 12 pairs of cranial nerves and these pairs of nerves passage through foramina in the skull, either individually or in groups. Cranial nerves are traditionally referred to by ...
The 12 cranial nerves are the abducent, accessory, facial, glossopharyngeal, hypoglossal, oculomotor, olfactory, optic, trigeminal, trochlear, vagus, and vestibulocochlear nerve. The cranial nerve functions are broken up into managing different aspects of your body’s daily tasks from chewing and biting to motor function, hearing, sense of smell, and vision.
Types of nerves may be established based on their anatomical location, which the names of nerves in the body typically reflect (e.g., "leg nerves"). It is conventional, however, to describe nerve types on the basis of their function: motor, sensory, autonomic or cranial.
The cranial nerves appear in pairs at the bottom surface of the brain. Their functions vary, but main functions include muscle control, helping the brain interpret the five senses, and controlling glands in the human body. Each cranial nerve pair controls specific functions of the human body. Nerve Names. The 12 cranial nerves each have a name ...
12 pairs of cranial nerves enable us to perform our daily routine in a comfortable and efficient way, as they take part of the information of our senses to the brain and the brain to some of our muscles and viscera. Here is a small guide to know a little more about what are the cranial nerves, their anatomy, their classification and their ...
Cranial nerves; CN 0 – Terminal CN I – Olfactory CN II – Optic CN III – Oculomotor CN IV – Trochlear CN V – Trigeminal CN VI – Abducens CN VII – Facial CN VIII – Vestibulocochlear CN IX – Glossopharyngeal CN X – Vagus CN XI – Accessory CN XII – Hypoglossal
Cranial nerves are basically named corresponding to their structure and functions. Olfactory and optic nerves emerge from cerebrum and all other 10 nerves emerge from the brain stem. Cranial nerve functions include all five senses and muscle movements. Here is the detailed list of Cranial nerves and their functions.
