Study Notes
Nerve Supply of the Scalp
- The auriculotemporal nerve supplies the scalp in front of the ear, originating from the mandibular branch of the trigeminal nerve (Cranial Nerve V).
- The greater occipital nerve provides sensory innervation to the scalp behind the ear, branching from the dorsal primary ramus of the second cervical nerve (C2).
Vascular Supply of the Face
- The facial artery is the primary vessel supplying blood to the face, a branch of the external carotid artery that provides oxygenated blood to facial regions.
Venous Drainage of the Face
- The facial vein is responsible for draining the face, collecting blood from the facial structures and draining into the internal jugular vein.
Nerve Supply to the Zygomatic Arches
- The zygomatic nerve, a branch of the maxillary division of the trigeminal nerve (V2), innervates the zygomatic arches, providing sensory function to the area.
