What nerve innervates the parotid gland?
glossopharyngeal nerve
Sensory innervation is supplied by the auriculotemporal nerve (gland) and the great auricular nerve. The parasympathetic innervation to the parotid gland has a complex path. It begins with the glossopharyngeal nerve (cranial nerve IX).
What is deep to the parotid gland?
Each parotid gland comprises a superficial lobe and a deep lobe divided by the facial nerve and the posterior facial vein.
Can lymphoma spread to parotid gland?
In cases where NHL affects the salivary glands, 75% arise within the parotid gland. The most common subtypes of NHL present in the salivary glands are extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) type, follicular B-cell lymphoma and diffuse large B-cell lymphoma.
Which nerve supplies the parasympathetic secretomotor innervation of the parotid gland?
The auriculotemporal nerve is also responsible for carrying general visceral afferent (sensory) stimuli from the gland as well. Remember the secretomotor pathway of the parotid gland with the mnemonic “IT has Lesser Options Anywhere”, which stands for; Inferior salivatory nucleus. Tympanic branch of 9th nerve.
Which cranial nerve Innervates the parotid salivary gland quizlet?
Parotid glands receive INDIRECT innervation via the glossopharyngeal nerve and otic ganglion.
How do you unblock a blocked salivary gland?
How is parotid duct obstruction treated?
- Increasing fluids.
- Putting moist heat on the area.
- Massaging the gland and duct.
- Sucking on candies to promote saliva secretion.
- Using pain medicines.
- Stopping use of any medicines that decrease saliva production, if medically possible.
Do benign parotid tumors have to be removed?
Treatment of Salivary Gland Tumors If you have a benign tumor, your doctor may recommend surgical removal to prevent it from becoming malignant over time. A benign tumor in the parotid gland can be removed using a surgical procedure called a partial superficial parotidectomy.
Is the oculomotor nerve sympathetic or parasympathetic?
Oculomotor nerve (III) is responsible for the control of the pupil (constriction) via parasympathetic fibres (this is opposed by dilator tone controlled by sympathetic pathways).
Where does the secretomotor of the parotid gland come from?
Parotid gland is pierced but not innervated by facial nerve. The parasympathetic secretomotor fibres to parotid arises from the glossopharyngeal nerve & reaches the gland via tympanic branch, the lesser petrosal nerve, the otic ganglion and the auriculotemporal nerve. Parotid capsule is derived from deep cervical fascia.
How does parasympathetic stimulation of the parotid gland work?
It begins with the glossopharyngeal nerve (cranial nerve IX). This nerve synapses with the otic ganglion (a collection of neuronal cell bodies). The auriculotemporal nerve then carries parasympathetic fibres from the otic ganglion to the parotid gland. Parasympathetic stimulation causes an increase in saliva production.
How is the facial nerve related to the parotid gland?
The anatomical relationships of the parotid gland are of great clinical importance – particularly during parotid gland surgery. The facial nerve (cranial nerve VII), gives rise to five terminal branches within the parotid gland. These branches innervate the muscles of facial expression.
How is the accessory duct related to the parotid gland?
The accessory duct gives off about 5 to 6 ductules that join the main parotid duct. The accessory duct is also superiorly related to the mandibular branch of the trigeminal nerve (CN V3). The buccal branch of the facial nerve (CN VII) also travels with the parotid duct as it goes to innervate the buccinator muscle.
