16
Q

Spinal root of the accessory nerve (CN XI) supplies what?

A

SCM & trapezius (only)

17
Q

Abduction of the scapula above 90 degrees is done by what mm.?

A

Trapezius and serratus anterior

18
Q

The triangle of auscultation is b/w what 2 superficial mm.?

A

Trapezius & latissimus dorsi

19
Q

What 3 mm. take origin in the vertebral column, insert into the scapula, and are supplied by the dorsal scapular nerve?

A

Levator scapulae, rhomboid major + minor

20
Q

Serratus anterior-OIIA + a.?

A

O-8 digitations in the upper 8 ribs
I-ventral aspect of the medical border of scapula
I-long thoracic nerve (roots of the brachial plexus (C5, 6, 7)
A-protracts the scapula forward (boxer’s m.)
*supplied by the lateral thoracic a.

21
Q

Injury to the long thoracic nerve could cause what?

A

“Winging of the scapula”(protracts scapula because the medial border of the scapula is no longer in contact w/the chest wall)

22
Q

What foramina are found only in cervical vertebrae?

A

Foramen transversarium (transmit vertebral vessels thru transverse processes)

23
Q

Which vertebra has no vertebral body or spinous process (consists of 2 lateral masses)

A

Atlas (C1)

24
Q

Which vertebra possesses an odontoid process (Dens), and has a strong bifid spinous process?

A

Axis (C2)

25
Q

What is the Yes-Yes joint (nodding)?

A

Atlanto-occipital joint

26
Q

What is the No-No joint?

A

Atlanto-axial joint (dens acts as a pivot)

27
Q

What mm. lay above the suboccipital mm.?

A

Trapezius and sternomastoid, then splenius capitis, then semispinalis capitis

28
Q

What all are in the suboccipital triangle?

A

-Superomedial: rectus c.p. major
-Lateral: obliquus c. superior
-Inferior: obliquus c. inferior
-roof: semispinalis capitus
-floor: posterior arch of atlas
(rectus cp minor doesn’t share in triangle)

29
Q

What aa. and nerves are within and above the suboccipital triangle?

A

Floor: vertebral a., suboccipital nerve

Roof (not triangle): occipital a., greater occipital nerve

30
Q

Suboccipital nerve info?

A
  • dorsal ramus of C1
  • Pure motor
  • supplies 4 suboccipital mm. & semisplenalis capitus
31
Q

Greater occipital nerve info?

A
  • dorsal ramus of C2
  • pure sensory
  • appears at lower border of inferior oblique, pierces semispinalis capitus & trapezius
  • supplies scalp up to the vertex
32
Q

Vertebral a. is branch of the _______?

A

subclavian a.

33
Q

Occipital a. is branch of the _______?

A

external carotid a. (ECA)

34
Q

Of the intrinsic (deep back) mm., the _____________ is superficial, the intermediate group is _______________, and the deep mm. are the ________________.

A
  • Splenius (capitis) m.
  • Erector spinae
  • Paravertebral mm.
35
Q

The deep mm. of the intrinsic back mm. include:

A

Semispinalis, multifidus, rotatores
