What is the parasympathetic division of the ANS?
Lymph nodes along the IJV that are ABOVE the omohyoid muscle
What is superior deep cervical nodes?
An injury here would put the superior poles of the thyroid gland, the larynx, the laryngopharynx, the carotid arteries, the IJVs, and the cervical vertebral column at risk
What is Zone 2 (of penetrating neck trauma)?
The connection between the superior cerebral veins in the subarachnoid space and the dural venous sinus
What are bridging veins?
Conveys presynaptic parasympathetic fibers to the pterygopalatine ganglion
What is the greater petrosal nerve?
Only contains sensory or motor information, not mixed
What is a root?
2 nerves that branch off of the roots of the brachial plexus

Levels where the trachea begins and ends
What is C6 to T4/5?

What is the superior and inferior petrosal sinuses?
The conjunctival sac is a thin space between these two layers of the conjunctiva
What is the palpebral conjunctiva and bulbar conjunctiva?
The nerve fibers that come from internal organs - allow visceral reflexes, signals fullness of hollow organs, pain
What is General Visceral Afferent?
NERVE that runs next to the vessel that supplies the postero-inferior part of the thyroid gland
What is the recurrent laryngeal nerve?
Constrictions of the esophagus
What is the cricopharyngeal constriction, the aortic constriction, the constriction produced by the left main bronchus, and the constriction at the point where the esophagus passes through the diaphragm?
Types of brain herniations
What is cingulate herniation, caudal herniation, tentorial herniation, and tonsillar herniation?
This vessel allows the facial vein to communicate with the pterygoid plexus in the infratemporal fossa
Level where the dural sac surrounding the spinal cord ends
What is S2?
The distal attachments of the trapezius
What is the clavicle, spine of scapula, acromion, and C7-C12 spinous processes?
This can cause vague retrosternal pain, coughing, and shortness of breath, and engorgement of the veins of the neck
What is a thymoma?
What is the anterior clinoid process, posterior clinoid process, dorsum sellae, and hypophyseal fossa?
The embryological origin and innervation of the muscles of facial expression
What is the 2nd pharyngeal arch and SVE fibers of the facial nerve?
Connection between the sympathetic trunk and the prevertebral ganglion
What is the splanchnic nerve?
Borders of the danger space
What is the alar fascia and prevertebral fascia?
Drains the thyroid gland into the brachiocephalic veins
What is the inferior thyroid veins?
CSF would be trapped inside the lateral ventricles if this was occluded
What is the interventricular foramen?
Four main vessels arising from the facial artery
What is the superior and inferior labial arteries, the lateral nasal artery, and the angular artery?
