How many pairs of cranial nerves are included in the sensory-somatic nervous system?

The sensory-somatic nervous system includes all the cranial nerves that are responsible for sensory and motor functions. There are a total of 12 pairs of cranial nerves, which consist of both sensory and motor nerves as well as some that have mixed functions. These nerves control a variety of functions, including sensory perception (such as vision, smell, hearing, and taste) and voluntary muscle movements.

The cranial nerves are numbered from I to XII, each with specific sensory or motor capabilities. This includes nerves like the olfactory nerve (I), which is sensory for smell, and the optic nerve (II), which is sensory for vision. Additionally, there are several other nerves that have motor functions, such as the oculomotor nerve (III), which controls most of the eye's movements.

In contrast, other choices like 10 pairs, 14 pairs, or 31 pairs do not accurately reflect the established anatomical knowledge regarding cranial nerves. The number of pairs is well-defined and established in medical literature, emphasizing the importance of knowing that there are specifically 12 pairs of cranial nerves in the sensory-somatic nervous system.
