Study Notes
Trigeminal Nerve Branches
- The trigeminal nerve has three major branches: ophthalmic, maxillary, and mandibular.
- Each branch has several smaller branches that further distribute sensory and motor functions.
- The trigeminal nerve is primarily responsible for sensation in the face, scalp, and oral cavity, and for motor functions of chewing muscles.
- The branches are shown in an image of a human head, illustrating their courses and connections to the skull and facial structures.
- Specific labeled structures on the image correspond to specific branches or components of the nerve.
