Study Notes
Trigeminal Nerve Branches
- The trigeminal nerve is a major cranial nerve (V) responsible for sensation in the face and motor functions of mastication.
- It has three major branches: ophthalmic (V1), maxillary (V2), and mandibular (V3).
- These branches are labeled in the image provided, with corresponding numbers.
- The ophthalmic branch (V1) provides sensory innervation to the upper face, including the forehead, scalp, and part of the orbit.
- The maxillary branch (V2) provides sensory innervation to the mid-face, including the cheeks, upper lip, and nasal cavity.
- The mandibular branch (V3) provides sensory innervation to the lower face, including the lower lip, chin, and part of the jaw, and motor function to the muscles of mastication.
- The image details the specific locations and pathways of each branch.
