Head and Neck Gross Anatomy Exam 1 Q’s
and A’s (Exam 1 for Head and Neck at Life

A broad thin sheet of muscle in the subcutaneous tissue of the neck - -
Platysma

- What is the Platysma's origin? Insertion? - -Origin is from the fascia
covering the pectoralis and deltoid muscles. Insertion is the inferior boarder
of the mandible, skin, and subcutaneous tissue of lower face.

- The Platysma recieves its nerve supply from? - -The Cervical Branch on
the Facial Nerve

- What are the three layers of the Deep Cervical Fascia? - -Investing Layer
Pretrachgeal Layer
Prevertebral Layer

- What is the function of the Deep Cervical Fascia? - -To Support the Viscera
Muscles, Vessels, and Deep Lymph Nodes. It also condenses around the
common carotid arteries, internal jugular veins, and vagus nerve to form the
carotid sheath.

- The Investing Layer of the Deep Cervical Fasica thickens to form the? - -
Stylomandibular Ligament

- Where is the Suprasternal Space? - -Between the two layers of the
Investing Layer of the Deep Cervical Fasica, which enclosed the SCM.

- The Pretracheal Layer of the Deep Cervical Fascia encloses the? - -
Infrahyoid, Sternohyoid, Sternothyroid, and Throhyoid Muscles as well as the
Thyroid Gland, Trachea, and Esophagus.

- What enclosed the Infrahyoid, Sternohyoid, Sternothyroid, and Throhyoid
Muscles as well as the Thyroid Gland, Trachea, and Esophagus. - -The
Pretracheal Layer of the Deep Cervical Fascia

- _______ Layer of the Deep Cervical Fascia forms a tubular sheath for the
vertebral column and the muscle sassociated with it. - -Prevertebral Layer

- The _____ parts of the sympathetic trunks are embedded in the pretracheal
layer. - -Cervical

, - What is the Carotid Sheath? - -A tubular, fascial investment the extends
from the cranial base to the root of the neck. It meets the pretracheal layers
of the fascia anteriorly and the prevertebral layers posteriorly.

- What is contained in the Carotid Sheath? - -Common and Internal Carotid
Arteries, Internal Jugular Vein, and Vagus Nerve as well as the deep cervical
lymph nodes, carotid sinus nerve, and sympathetic nerve fibers.

- The Alar Fascia is attached along the? - -Midline of the Buccopharyngeal
Fascia from the Cranium to C7 Vertebra

- What forms a pulley or trochlea through which the intermediate tendon of
the digastric muscles passes through, suspending the Hyoid? - -Pretracheal
Layer of the Deep Cervical Fascia

- Boarders of the Anterior Triangle? - -Anterior: Median Line if the Neck
Posterior: Anterior Boarder of the SCM
Superior: Inferior Boarder of Mandible
Floor: Pharynx, Larynx, Thyroid Gland
Roof: Platysma

- What are the subdivisions of the Anterior Triangle? - -Submental
Submandibular
Carotid
Muscular

- What triangle lies inferior to the chin in a suprahyoid area? - -Submental

- The Anterior Bellies of the digastric Muscles boarder what triangle
laterally? - -Submental Triangle

- Floor of the Submental Triangle? - -Mylohyoid Muscles

- The Anterior Jugular Vein is formed by - -Small veins in the Submental
Triangle that meet together

- Floor of the Submandibular Triangle - -Mylohyoid Muscles, hyoglossus, and
middle constrictor of pharynx

- Contents of the submandibular triangle - -The submandibular gland,
submandbular lymph nodes lie on each side of the submandibular gland,
hypoglossal nerve (12th cranial nerve) nerve to mylohyoid nerve (supplies
the mylohyoid and anterior belly of digastric), parts of the facial artery, facial
vein and submental artery (a branch of facial artery)
