Flashcards in Appendicular Muscles Deck (79):
1

What are the anterior and posterior thorax muscles responsible for moving?

Scapula (stabilize & move)
Upper limb
(Kinda irrelevant)

2

Anterior muscles

Pectoralis major and minor
Serrated anterior
Subclavius

3

Posterior muscles

Latissimus dorsi
Trapezius
Levator scapulae
Rhomboids

4

Under the clavicle, extending from the clavicle to the first rib
(Steadies clavicle during movement if pectoral girdle)

Subclavius

5

Thin muscle deep to the pectoralis major
(Moves scapula so glenoid cavity can rotate downward, elevates ribs)

Pectoralis minor

6

Flat, jagged muscles from origin on ribs
Inserts on scapula
"Boxer muscles"

Serratus anterior

7

Stabilizes, raises, retracts, and rotates the scapula

Trapezius

8

Elevate and adducts scapula

Lector scapulae

9

These stabilize the scapula and work with middle fibers of trapezius to retract the scapula when "squaring" the shoulders

Rhomboids

10

Prime mover Muscles that moves the humerus

Pectoralis major
Latissimus dorsi
Deltoid muscles

11

2 shoulder joints that do not arise from the scapula

Pectoralis major
Latissimus dorsi

12

Large flat muscle with convergent fibers that have multiple origins from the clavicle, sternum, costal cartilage, & aponeurosis of external obliques

Pectoralis major

13

A prime mover of arm flexion, medial rotation, and adduction
(Climbing, throwing)

Pectoralis major

14

Broad flat triangular shaped muscle with numerous origins from the lumbodorsal fascia etc

Latissimus dorsi

15

Prime mover of arm extension
(Antagonist of pectoralis minor), adductor of arm, medically rotates arm at shoulder

Latissimus dorsi
(Hammering, swimming)

16

Thick triangular shaped multipectinate muscle
(Prime mover of arm abduction, antagonist of pectoralis major & latissimus dorsi)

Deltoid

17

Helps form part of axillary wall
(Extends, medically rotates, adducts arm)

Teres major

18

Flexion & adduction of arm
Synergist if pectoralis major

19

Forms posterior wall of axilla
Helps hold head of humerus in glenoid cavity

20

Supraspinatus

21

Infraspinous fossa

22

Often inseparable from the infrasoinatus

Teres minor

23

Strength and stability of shoulder by these 4 muscles
What do they make up?

Subscapularis, supraspinatus, infraspinatus, teres minor
Rotator cuff

24

Repetitive overhead motion causes continual pinching of the supraspinatus tendon
(Can result in muscle pulling away from humerus)

Impingement syndrome

25

Whats the scientific name of rotator cuff?

30
