Superficial back 1

Question 0

What vertebra make up the sacrococcygeal curvature?

Answer 0

S1 to Co0

Question 1

What is the pectoral girdle?

Answer 1

Clavicle and scapula

Question 2

Vertebral curvature: secondary

Answer 2

Cervical and lumbar

Question 3

What vertebra make up the lumbar curvature?

Answer 3

L1 to L5

Question 4

The LS innervated by the _________ rami of ___________.

Answer 4

Anterior (ventral).

C3 and C4

Question 5

What vertebra make up the thoracic curvature?

Answer 5

T2 to T12

Question 6

The latissimus dorsi acts directly on the ______ and indirectly on the ________.

Answer 6

Directly - shoulder joint

Indirectly- pectoral girdle

Question 7

What does the trap attach to? BASICS

Answer 7

The pectoral girdle to the skull and vertebral column.

Question 8

What does the levator attach to? What does it do?

Answer 8

It attaches to the posterior tubercles of the transverse processes of C1-4 AND the medial (vertebral) border of the scapula.
It helps the trap in elevating the scapulae and maintaining its level.

Question 9

What vertebra make up the cervical curvature?

Answer 9

C1 to T2

Question 10

Which muscle groups are considered extrinsic?

Answer 10

Superficial and intermediate

Question 11

What is the rhomboid minor attached to?

Answer 11

Ligamentum nuchae and C7/T1 to the medial border of the scapula

Question 12

What is the LD innervated by? And what does it do?

Answer 12

The thoracodorsal nerve.

It extends, adducts and medially rotates the humerus.

Question 13

Which muscles are involved in upper limb rotation?

Answer 13

Trapezius and latissimus dorsi.

Question 14

What is the levator scapulae innervated by?

Answer 14

The dorsal scapular nerve AND cervical nerves C3 and C4.

Question 15

What does extrinsic mean?

Answer 15

It means that these muscles are involved in limb movement and respiration.

Question 16

What are the rhomboids innervated by?

Answer 16

The dorsal scapular nerve and C3 and C4.

Question 17

What is the rhomboid major attached to?

Answer 17

Originates in the spines of T2-5 and inserts into the medial border of the scap

Question 18

Describe the location of the rhomboids. What do they do?

Answer 18

They pass inferolaterally from the vertebral to the medial border of the scapula.
They retract the scapula (bracing back the shoulders) and elevate and maintain is level. It also helps fix the scapula to the thoracic wall.

Question 19

What muscle group is involved with limb movement? And which with respiration?

Answer 19

Superficial muscles are involved in limb movement and is intermediate muscles are involved in respiration.

Question 20

What are the 3 fiber groups of the trapezius and what do they do?

Answer 20

Superior- elevates the scapula
Middle- adduct the scapula (move medially)
Inferior- depress (move inferiorly) and adduct the scapula

Question 21

What are the 3 origins and insertions of the trapezius?

Answer 21

1. The descending part originates from the occipital bone and the spinous processes of C1 to C7 and inserts onto the lateral third of the clavicle.
2. The transverse part originates from the aponeuroses at the spinous processes of T1 to T4 and inserts onto the acromion of scap.
3. The ascending part originates from the spinous processes of T5 to T12 and inserts onto the scapular spine.

Question 22

What does the trapezius do in general? And what is it innervated by?

Answer 22

It assists in suspending the upper limb. It’s innervated by CNXI11 (accessory nerve).

Question 23

Vertebra curvatures: primary

Answer 23

Thoracic and sacrococcygeal

Question 24

What muscles make up the deep extrinsics?

Answer 24

Levator scapulae and rhomboid major/minor

Question 25

Axial skeleton is composed of

Answer 25

Skull
Vertebral column
Rib cage
Hyoid

Question 26

Number of vertebrae

Answer 26

33
7 cervical
12 thoracic 
5 lumbar 
5 sacral 
5 coccygeal

Question 27

What is the cough muscle?

Answer 27

The latissimus dorsi

Question 28

What are the 4 origins of the latissimus dorsi? And what insertion do they share?

Answer 28

1. Thoracic vertebrae 6/7-12
2. Scapula
3. Costals lesser tuberosity of the humerus
4. Iliac crest
