Module 34 - Skeletal Muscle Gross Anatomy Flashcards
what are the 2 muscles that attach arm to thorax?
pectoralis major and latissimus dorsi
the pectoralis major is involved in which movements
flexion, adduction and medial rotation. extension if arm is already extended
the latissimus dorsi is involved in which movements
extension, adduction and medial rotation
what is the main movement that the deltoids are involved in
abduction and medial + lateral rotation of arm
what is a movement that the deltoid and the pectoralis major have in common
both act as flexors and extensors of the shoulder
what are the muscles involved in the rotator cuff
use SITS
subscapularis
infraspinatus
teres minor
supraspinatus
what is the main role of the muscles of the rotator cuff
holding humerus in the glenoid cavity
forming a cuff or cap over the proximal humerus
compare the SLITS muscles
which muscles in the rotator cuffs do not participate in medial rotation
supraspinatus and infraspinatus
what are the muscles of the movement of the elbow involved in extension
triceps brachii
anconeus
what are the muscles of the movement of the elbow involved in flexion
biceps brachii
brachioradialis
brachialis
what are the muscles of the movement of the elbow involved in supination
supinator
biceps brachii
list all of the muscles involved in forearm movement/movement of the elbow
triceps brachii
anconeus
biceps brachii
brachioradialis
brachialis
supinator
pronator quadratus
pronator teres
differentiate muscles on anterior and posterior sides of the wrist, hand and finger for movement
