Face Flashcards
Motor innervation of the face
Facial nerve and mandibular nerve
Cutaneous innervation of the face
Trigeminal nerve
Parotid gland
Largest of the three paired salivary glands
What is the apex of the parotid gland?
Posterior to the angle of the mandible
What is the base of the parotid gland?
Related to the zygomatic arch
What are the contents of the parotid gland?
Superficial to deep:
- Parotid plexus of the facial nerve
- Retromandibular vein
- External carotid artery
What innervates the muscles of the face?
Facial nerve (CN VII) via its posterior auricular branch
Where does the facial nerve exit?
Stylomastoid foramen
What are the two parts of the oral cavity?
Oral vestibule and oral cavity proper
What are the three salivary glands?
Parotid, submandibular, and sublingual gland
Function of the tongue
Assists with mastication (chewing), taste, deglutition (swallowing), articulation (speech), and oral cleansing
Innervation of the extrinsic muscles of the tongue
Hypoglossal nerve (motor), lingual nerve (sensory), chorda tympani (sensory), and glossopharyngeal (sensory)
Role of tongue and soft palate in swallowing
Soft palate is initially tensed to allow the tongue to press against it, squeezing the bolus of food to the back of the oral cavity proper - the soft palate is then elevated posteriorly and superiorly against the wall of the pharynx, thereby preventing passage of food into the nasal cavity
What are the bones that form the orbit?
- Orbital part of the frontal bone
- Ethmoid bone
- Frontal process of the zygomatic bone and greater wing of sphenoid
- Maxilla and partly by zygomatic and palantine bones
- Lesser wing of the sphenoid
What does the hard palate separate?
Anterior part of the oral cavity from the nasal cavity
