Front 1

Accesory nerve innervates

Back 1

trapezius muscle, sternocladomastoid

Front 2

. Investing layer/superficial layer/cervical fascia which encloses

Back 2

trapezius and sternocladomastoid

Front 3

Prevertebral fascia as it descends past the C7 it continues as

Back 3

thoracolumbar fascia and both can be referred to as vertebral fascia

Front 4

Visceral fascia is related to

Back 4

upper part of the respiratory tract and upper digestive tract, thyroid gland

Front 5

Visceral fascia can be divided into 2

Back 5

one that is anteriorlateral to the trachea which is called pretrachial fascia. . Buckle pharyngeal fascia is the most posterior aspect of the visceral compartment

Front 6

Carotid sheath is formed by the close association of

Back 6

visceral, investing and prevertebral fascia

Front 7

Retropharyngeal space. Its boundaries are

Back 7

anteriorly: the posterior aspect of the buckle-pharyngeal fascia and posteriorly the prevertebral fascia

Front 8

The fucnction of the retropharyngeal fascia is to

Back 8

allow the movemetnt of visceral fascia during swallowing and fonating

Front 9

Alar fascia. The attachment of the investing fascia follows around the mandible jumps over to the mastoid process, and to the superior nuchal line so it deliniates

Back 9

the superior extend of the neck

Front 10

Anteriorly the prevertebral layer blends with anterior aspect of the periostium of vertebral column and anterior longitudinal ligament so it is a definitive sheath because

Back 10

it’s no longer present once it reaches its inferior part. Mostly due to the fact that there are no more prevertebral muscles down the neck

Front 11

. Pretracheal space is in between

Back 11

the infrahyoid fascia and pretracheal fascia. All these spaces are important because they can store abscess.

Front 12

Borders of the posterior triangle

Back 12

Apex: Occipital Bone
Anterior: posterior border Sternocleidomastoid
Inferior: Middle third of clavicle
Posterior: anterior border trapezius
Superficial (roof): superficial layer of the deep cervical fascia
Deep (floor): splenius capitis, levator scapulae, posterior scalene, middle scalene, omohyoid, and anterior scalene.
covered by prevertebral fascia

Front 13

in contact with the deep surface of the platysma muscle

Back 13

• Supraclavicular nerves, transverse cervical nerve, and external jugular vein

Front 14

Platysma muscle sits in which fascia>

Back 14

superficial fascia

Front 15

Platisma muscle inferiorly passes

Back 15

superior to the clavicle and it attaches to the superficial fascia of the deltoid and pectorial regions

Front 16

Plastima muscle superiorly attaches to

Back 16

Angle of the mouth, mandible, orbicularis oris muscle, and skin of the cheek,

Front 17

Platysma is innvervated by

Back 17

Facial Nerve

Front 18

Between the two heads (sternal head and clavicular head) of the sternocleidomastoid there is

Back 18

The space where a catheter can be inserted into the internal jugular vein

Front 19

External Jugular vein is found in between which fascia?

Back 19

Superficial fascia deep to the platisma muscle

Front 20

Which fascia is pierced by the external jugular vein

Back 20

superficial layer of the deep cervical fascia/investing fascia to then go and drain into the subclavian vein (around the middle of the clavicle)

Front 21

*stab wound to the external jugular vein causes lumen of the vein to be

Back 21

held open and you start to suck air into it causing patient to turn and hear churning noise so Dr. need to be finger over hole

Front 22

External Jugular vein is formed by

Back 22

posterior retromandibular vein and posterior auricular vein behind the angle of the mandible

Front 23

Cervical Plexus gives cutaneous innvervation to

Back 23

to the neck and posterior head

Front 24

Cervical Plexus can be anesthetized but one most be extremely careful because

Back 24

phrenic nerve so don’t want to give to someone who has pulmonary problems

Front 25

Located at

Back 25

: 2/3 up the SCM – nerve point of the neck

Front 26

Great auricular nerve (C2 and C3) innervates

Back 26

skin of the lower part of the ear and skin extending from angle of mandible to mastoid process (only part of face that has sensory innervation not from CN V)!!!

Front 27

Lesser occipital nerve (C2) innverates

Back 27

part of the scalp that is immediately behind the ear

Front 28

Transverse cervical nerve (C2, C3) innervates

Back 28

skin of the anterior triangle of the neck

Front 29

Supraclavicular nerve (C3, C4) innervates

Back 29

the skin of the shoulder

Front 30

Spinal Accessory Nerve (CN XI) location in relation to the investing fascia

Back 30

• Located deep to the investing layer of deep cervical fascia

Front 31

Spinal Accessory Nerve (CN XI) innervates

Back 31

sternocleidomastoid and trapezius.
