label the veins
what does the investing fascia of the neck encircle?
the trapezius and the sternocleidomastoid
what does the carotid sheath encircle?
the internal jugular vein, common carotid artery and the vagus nerve, as well as deep cervical lymph nodes
what does the pretracheal fascia encircle?
the thyroid glands, trachea and esophagus
what does the prevertebral fascia encircle?
most of the neck muscles and vertebrae
what are the borders of the anterior and posterior triangles f the neck respectively?
the anterior borders are the madnible superiorly, the midline of the neck medially, and the medially part of the sternocleinomastoid laterally. The posterior triangle borders are the posterior edge of the sternocleidomastoid anteriorly, the anterior edge of the trapezius posteriorly and the clavicle inferiorly
what are the roofs and floors of the anterior and posterior triangles respectively?
the floor of the anterior is the pretracheal fascia and the floor of the posterior is the prevertebral while the roof for both is the investing fascia.
the subcutaneous tissue of the neck AKA the superficial cervical fascia contains what?
the platysma
What is the major pathway for spread of infection in the neck?
the retropharyngeal space
The anterior triangle of the neck is divided into what subsequent triangles and what is contained in each?
The submandibular triangle contains the submandibular gland, submandibular lymph nodes, hypoglossal nerve, parts of facial artery and vein
the submental triangle contains the submental lymph nodes and small veins that unite to form the anterior jugular vein.
The carotid triangle contains the carotid artery, branches, internal jugular and branches, vagus, external carotid and branches, hypoglossal nerve and superior root of ansa cervicalis, spinal accessory nerve, thyroid gland, larynx, pharynx, deep cervical lymph nodes, branches of cervical plexus
the muscular triangle contains the sternothyroid and sternohyoid muscles, and thyroid and parathyroid glands
The posterior triangle of the neck is divided into what regions and what is contained in those regions?
the occipital triangle contains external jugular, spinal accessory, trunks of brachial plexus, transverse cervical artery, and cervical lymph nodes
the subclavian triangle contains the subclavian artery and vein, suprascapular artery, and suprascapular nodes.
what is the action and innervation of the platysma?
it makes the corner of the lips go down in a frown and draws the skin of the neck superiorly when the teeth are clenched
what are the actions and innervation of the sternocleidomastoid?
unilateral contraction results in laterally flexing neck and tilting head superiorly in that position. Bilateral contraction results in extending the neck at the atlanto occipital joint, jutting chin forward and touches chin to the manubrium. Motor innervation is via the spinal accessory nerve and C2 and C3 for pain and proprioception
what are the four muscles seen in the floor of the posterior triangle (in order from superior to inferior)? What muscle can be seen when the sternocleidomastoid is reflected antero-medially?
splenius, levator scapulae, middle scalene and posterior scalene. The anterior scalene can be seen if the sternocleidomastoid is reflected.
What important nerve runs transversly through the middle of the posterior triangle?
the spinal accessory
Imagine the cervical plexus as a clock. Name all the nerves starting at 12 o'clock and continuing closckwise.
great auricular, transverse cervical, supraclavicular nerves, spinal accessory (only motor and only nerve in plexus that is deep to the investing fascia), and the lesser occipital.
what are the branches of the subclavian from medial to lateral?
the vertebral artery, the thyrocervical trunk (superiorly) and internal thoracic (inferiorly), and the costocervical trunk
what are the branches of the thyrocervical trunk?
the suprascapular, the transverse cervical, and the inferior thyroid
what are the branches of the external carotid from inferior to superior?
superior thyroid, ascending pharyngeal, lingual, facial, occipital, posterior articular, superficial temporal, and maxillary
where is the mylohyoid and what are its actions and innervations?
connects to mandible and hyoid, and it elevates the hyoid, floor of mouth and tongue during swallowing and speaking; it is innervated by the motor branch of the mandibular nerve (branch of trigeminal)
where is the glenohyoid and what is its innervation and actions?
it connects the mandible and the hyoid, it is innervated by C1 via the hypoglossal, and it shortens floor of mouth and widens the pharynx
where is the stylohyoid, what are its actions and innervation?
it connects the styloid process of the temporal to the hyoid. it elevates and retracts the hyoid thus elongating the floor of the mouth and it is innervated by the stylohyoid branch of the facial nerve.
where is the digastric located, what is its action and innervation?
the anterior belly originates from the mandible then it travles under the fibrous sling of the digastric which is attached to the hyoid and becomes the posterior belly which attaches to the mastoid process of temporal bone. It depresses mandible against resistance, elevates and steadies hyoid during swallowing and speaking. the anterior belly is innervated by the mandibular nerve (branch of trigeminal) while the posterior belly is innervated by the facial nerve.
the sternohyoid is located where, does what and is innervated by...
located between hyoid and clavicle/manubrium, depresses hyoid after elevation during swallowing, and is innervated by C1-C3 by a branch of the ansa cervicalis
the omohyoid is located where, does what and is innervated by...
descends inferiorly from the hyoid (superior belly) and through the fascial sling on the clavicle to the scapula (inferior belly). It depresses, retracts and steadies the hyoid. It is innervated by C1-C3 via a branch of the ansa cervicalis
the sternothyroid is located where, does what, and is innervated by...
between the thyroid cartilage and the posterior manubrium. It depresses the hyoid and larynx and is innervated by C2 and C3 via a branch of the ansa cervicalis
the thyrohyoid is located where and does what and is inervated by?
between the hyoid and the the thyroid cartilage. It depresses the hyoid and elevates the larynx via the C1 on the hypoglossal
the costo-cervical trunk branches into what?
the first posterior intercostal artery and the deep cervical artery, note that the deep cervical artery eventually anastamoses with the occipital artery
from posterior to anterior, what nerves are deep to the posterior belly of the digastric?
the spinal accessory, the vagus, and the hypoglossal
how do sympathetic nerves get to the head and neck?
by the plexuses they form on the carotid and vertebral arterial systems
