Question: 3 different compartments of the neck and their Cervical FasciaAnswer: 1.Vertberal: fa.(surrounds vertebral column and associated muscles).
2.Visceral: Pretracheal fa.(surrounds thyroid, parathyroid, trachea, esophagus).
3.Vascular: Alar fa.(Common/Internal carotid A, Int Jugular V, Vagus N)**Carotid Sheath Question: fasciaAnswer: most superficial, associated closely with m. Question: Retropharyngeal Answer: Located between the posterior Pretracheal fascia and the anterior Prevertebral fascia. Buccopharyngeal fascia is found here. Allows movement of visceral comp. on top of vertebral comp. **Allows spread of infection to mediastinum. Question: Location of structures in SheathAnswer: : Common Carotid A. (int carotid A superiorly)
Lateral: Internal jugular V.

2.Occipital A.
3.Posterior A (last preterminal Branch off ECA). Question: Anterior off External Carotid A. (in order)Answer: 1.Superior Thyroid A (first branch off ECA).
2.Lingual A.(just superior to Sup. Thy. A).
3.Facial A. (either in ith Lingual A or immediately superior). Question: Terminal Branches of Carotid AAnswer: 1.Maxillary A (originates within the parotid gland, moves anteriorly deep to condylar neck of mandible to reach infratemporal fossa).
2.Superficial Temporal A (gives off a transverse facial A and then passes to ext. auditory meatus). Question: Some Aggressive Find Odd Positions More StimulatingAnswer: Branching pattern of ECA: SThyA, APA, LA, FA,OA,PAA, MA, Question: Anterior Veins of neck (Anterior to )Answer: 1.Ext Jugular V. (Angle of mandible to subclavian V)
2.Communticating V (connects Ext Jugular to Ant Jugular vein).
3.Anterior V (anterior midline of neck, moves laterally at clavicle deep to SCM to empty into Ext Jugular V). Question: fibers of cervical plexusAnswer: Sensory nerves: Lesser occipital (C2, up occipital bone), Greater Auricular (C2-3, ascends up to ear), Transverse cervical (C2-3, transversely across neck), Supraclavicular (C3-4, descend and run superior to clavicle). Question: Erb's Point (Punctum )Answer: Location where the nerves are exiting the neck, Would case pain if hit here. Question: Anterior Rami of Cervical Answer: Motor Nerves. The Phrenic N (C3-5), Ansa (C1-4). Question: of Ansa CervicalisAnswer: Superior C1-2: innervates Geniohyoid and Thyrohyoid muscles.**Also gets from CNXII.
Inferior: C3-4 innervates infrahyoid muscles Question: Posterior cervical Answer: Trapezius m., cutaneous branches of posterior rami, suboccipital triangle (Deep) Question: Sternocleidomastoid Answer: Contains SCM m., Ext V, Greater Auricular N, Transverse cervical N. Question: Posterior (Lateral Cervical region)Answer: : SCM, Trapezius, clavicle.
Can be divided into: Occipital triangle and subclavian triangle. Question: Contents of triangle Answer: 1.Spinal accessory n.
2.Erb's point (cervical plexus).
3.Trunks of brachial plexus.
4.Transverse cervical A (off the 3rd/lateral part of ). Question: of Subclavian TriangleAnswer: 1. Ext V.
2. Occipital A. (posterior branch of EJV).
3. Subclavian A and V (3rd/lateral part) Question: TriangleAnswer: Boundaries: Median line of neck, SCM, .
Can be divided into: Submental, Submandibular, carotid, and muscular triangles Question: of Submental TriangleAnswer: submental lymph nodes, Anterior v, Mylohyoid muscle. Question: Contents of Submandibular Answer: 1.submandibular .
