Your cranial nerves are a set of 12 nerves that send electrical signals between your brain and different parts of your head, face, neck and torso.
Cranial nerves are generally named according to their structure or function. For example, the olfactory nerve (I) supplies smell, and the facial nerve (VII) supplies the muscles of the face. Because Latin was the lingua franca of the study of anatomy when the nerves were first documented, recorded, and discussed, many nerves maintain Latin or Greek names, including the trochlear nerve (IV ...
The 12 pairs of cranial nerves are specialized bundles of axons that connect the brain directly to the head, neck, and trunk. Unlike most nerves, they bypass the spinal cord entirely, allowing for rapid transmission of sensory and motor data. Inferior view of the brain showing the 12 pairs of cranial nerves.

An introduction to the cranial nerves. Here you can learn the names, anatomy and functions of each cranial nerve as well as mnemonics to remember them.
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault (Figure 1). The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws. The rounded brain case surrounds and protects the brain ...
Explore the cranial nerves as a group, including their core functions, pathways and roles in head and neck anatomy. A clear introduction for medical students and clinicians.
cranial nerves nerves that are attached to the brain and pass through the openings of the skull; see anatomic Table of Nerves in the Appendices. There are 12 pairs of cranial nerves, symmetrically arranged so that they are distributed mainly to the structures of the head and neck. The one exception is the vagus nerve, which extends down to serve structures in the chest and abdomen. Some of the ...
