C. Superficial veins

l. External jugular vein

a. Formed posterior to the angle of the mandible by the union of the posterior auricular
vein and posterior division of the retromandibular vein.

b. Descends posteriorly on the sternocleidomastoid adjacent to the
great auricular nerve; penetrates the deep fascia posterior to the
sternocleidomastoid and drains into the subclavian vein
SUPERFICIAL VEINS

ANTERIOR JUGULAR VEIN
-formed by?
-superior to the?
2. Anterior Jugular Vein

a. Formed by the coalescence of veins under the chin; descends near
the anterior cervical midline, pierces the deep fascia, and drains into
the external jugular vein posterior to the sternocleidomastoid

b. Superior to the jugular notch, the anterior jugular veins may communicate via a jugular venous arch.
DEEP FASCIA

INVESTING FASCIA
II. Deep Fascia

B. Investing fascia: lies deep to the superficial fascia; originates in the posterior cervical midline and, from posterior to anterior, invests the trapezius, forms the roof of the posterior triangle ofthe neck (region between the trapezius and sternocleidomastoid), invests the sternocleidomastoid and infrahyoid muscles, and then becomes continuous with the investing fascia to the opposite side in the anterior cervical midline

-lies deep to...
c. Prevertebral Fascia

1. Lies deep to the investing fascia

2. Originates in the posterior cervical midline and, from posterior to anterior, ensheaths the capitis, levator scapulae, scalenus posterior, scalenus medius, scalenus anterior, longus capitis, and longus colli, and then becomes continuous with the prevertebral
fascia of the opposite side in the anterior cervical midline
