Term
|
Definition

|
|
Term
| Why would sucking on a lemon cause pain? |
|
Definition

Term
| What is the parotid bed and what is it composed of? |
|
Definition
- Place where the parotid gland lies
- formed by bones and muscles
- anteriomedially = ramus f the mandible and two muscle (masseter and medial pterygoid ms)
- Posteromedially = mastoid and styloid processes and associated ms (scm, post belly of digastric, stylohyoid)
|
|
|
Term
| What separates the parotid gland from the ICA, IJV, and IX-XII? |
|
Definition
| styloid process and its muscles |
|
|
Term
| What three important things pierce the parotid gland? (superficial to deep) |
|
Definition
- Facial nerve
- External jugular vein
- External carotid artery
|
|
|
Term
| Does benign or maligant tumors of the parotid gland invade and cause facial paralysis? |
|
Definition
|
|
Term
| The parotid fascia is continous with which layer of fascia? |
|
Definition
|
|
Term
| What is a common symptom of mumps relevant to the parotid region? |
|
Definition
| Chewing can cause pain because of the swollen gland |
|
|
Term
| What cranial nerve sends parasympathetic fibers to the parotid gland? What ganglion is involved? |
|
Definition
|
|
Term
| Tract parasympathetic fibers of CN9 to the parotid gland |
|
Definition
- Leaves jugular foramen
- Branches off inferior ganglion as tympanic nerve
- enters tympanic canaliculi and becomes lesser petrosal nerve after tympanic plexus
- leaves inner ear along lesser petrosal hiatus
- leaves skull via foramen ovale
- enters infratemporal fossa
- joins otic ganglion
- exits as the auriculotemporal nerve
- innervates parotid gland
|
|
|
Term
| How do sympathetic fibers innervate the parotid gland? |
|
Definition
| Involves thoracic spinal cord, superior cervical ganglion, external carotid plexus |
|
|
Term
| Sensory nerve to the parotid gland, what nerve is it? |
|
Definition
| Auriculotemporal nerve, V3 |
|
|
Term
| What are the symptoms of Frey's Syndrome? |
|
Definition
| sweating on the skin over the parotid gland |
|
|
Term
| What is the etiology of Frey's syndrome |
|
Definition
- Upon damage of the parasympathetic fibers in the auriculotemporal n, healing begins
- Healing sometimes involves the parasympathetic fibers to innervate the sweat glands of the face
- Thus when eating (should be stim parotid), one stimulates the sweat glands (they are cholinergic)
|
|
|
Term
| What is the arterial supply to the parotid gland? |
|
Definition
| External carotid that branches into the maxillary artery and superficial temporal artery |
|
|
Term

|
Definition
|
|
Term

|
Definition
|
|
Term

|
Definition
| Superficial temporal vein and maxillary vein |
