2) Leavtor scapulae
3) Splenius capitus

21
Q

Name the two subdivisions of posterior triangle

A

1) occipital triangle

2) supraclavicular triangle

22
Q

T/F - Occipital triangle is below omohyoid and contains subclavian artery and vein

A

False, it is above omohyoid and contains upper deep cervical lymph nodes and accessory nerve

23
Q

T/F - Supraclavicular triangle is above omohyoid and contains upper deep cervical lymph nodes and accessory nerve

A

False, it is below omohyoid and contains subclavian artery and vein

24
Q

T/F - Sternocleidomastoid extends from manubrium and medial 1/3 of clavicle to anterolateral mastoid

A

True

25
Q

What are the actions of SCM?

A
  • On own it tilts and rotates head

- together it flexes head and raises sternum

26
Q

T/F - Trapezius connects from external occipital protuberance and superior nuchal line to T12 in the midline and laterally to lateral clavicle and acromium

A

True

27
Q

What are the actions of trapezius muscle?

A

Pulls shoulders back, also rotates shoulder, raises arm and extends head on neck

28
Q

What is motor nerve for trapezius muscle and SCM?

A

spinal accessory which runs deep to both muscle

29
Q

What is sensory innervation for trapezius and SCM?

A

Ventral cervical rami (travels with accessory)

30
Q

Digastric ___________ attaches to digastric fossa on medial surface of mandible near midline.

A

Anterior belly

31
Q

Digastric _____________ runs through a fibrous sling attached to body and greater horn of the hyoid. _________ pierces stylohyoid which attaches to the styloid process

A

Intermediate tendon, intermediate tendon

32
Q

Digastric __________ is attached to mastoid notch (mesial to mastoid)

A

Posterior belly

33
Q

What are the two actions of digastric bellies and intermediate tendon?

A
  • Depresses mandible

- Elevates hyoid

34
Q

Which nerve innervates posterior belly, and anterior belly?

A
  • Facial nerve for posterior belly

- Mylohyoid nerve for anterior belly

35
Q

T/F - Omohyoid superior belly goes from body of hyoid to intermediate tendon

A

True

36
Q

T/F - Omohyoid inferior belly stretches from tendon to upper body of scapula and is attached to clavicle and rib 2 by a fascial sling

A

False, it’s rib 1

37
Q

What are the two actions of omohyoid?

A

Depresses hyoid, tenses deep cervical fascia during prolonged inspiration

38
Q

What are the innervations of omohyoid?

A

Ventral branches of cervical nerves (ansa cervicalis) - sensory & motor)

39
Q

T/F - SCM delineates triangles of neck and superficial and deep lymph nodes

A

True

40
Q

What are the features lateral to SCM?

A
  • External jugular
  • lesser occipital nerve
  • greater auricular nerve
  • transverse cutaneous nerve of neck
41
Q

Which features is deep to/supplying SCM?

A
  • Spinal accessory nerve

- Intermediate tendon omohyoid

42
Q

T/F - (Digastric belly) hypoglossal nerve is superficial to intermediate tendon

A

False, it’s deep to intermediate tendon

43
Q

T/F - posterior belly digastric is used to distinguish descending pharyngeal artery (Below) from occipital (behind) from posterior auricular artery (above)

A

False, it’s ascending pharyngeal artery

44
Q

T/F - Digastric posterior belly is closely associated with stylohyoid

A

True

45
Q

T/F - Jugulodigastric nodes is deep/just inferior to digastric posterior belly

A

True

46
Q

T/F - Omohyoid belly divides muscular and supraclavicular triangle in anterior triangle

A

False, it divides muscular and carotid triangle in anterior triangle

47
Q

T/F - Omohyoid muscle divides posterior triangle into occipital and supraclavicular triangle

A

True

48
Q

T/F - Omohyoid arbitarily divides superficial cervical lymph nodes into upper/superior and inferior/lower

A

False, it’s deep cervical lymph nodes
