Study Notes
Facial Nerve and Associated Structures
- The mandibular branch of the facial nerve supplies the muscles of the lower lip.
Blood Supply of Lower Lip
- The labial artery is responsible for the blood supply of the lower lip.
Landmarks of Facial Nerve
- The tragal pointer is a landmark for the facial nerve in the parotid gland.
Muscles and Mastication
- Trismus is caused by the spasm of the medial pterygoid muscle.
- The accessory muscle of mastication is the buccinator.
Parotid Duct
- The parotid duct opens into the second maxillary molar.
Brain Structures
- The mammillary body projects via the fornix.
- Broca's area and Wernicke's area are connected by the arcuate fasciculus.

Description
Test your knowledge on facial nerve branches, lower lip blood supply, facial nerve landmarks, and muscles responsible for trismus. Identify the branches of the facial nerve, lower lip blood vessels, and key landmarks in the parotid gland. Determine the muscle causing trismus.
