59- gluteus medius: origin: lateral ililum |insertion: greater trochanter | action: abduct thigh & medially rotate thigh

58-gluteus minimus: origin: lateral ilum | insertion: greater trochanter action: abduct thigh and medially rotate thigh

what muscle is this (1)

origin, insertion, action, innervation?

piriformis

origin: anterior surface of sacrum

insertion: greater trochanter

183-Triceps brachii lateral head

181-Triceps brachii medial head

radial nerve

Id muscles

what muscle groups do each of those belong to?

A.teres minor (deltoid group)

B.teres major (latissimus group)

ORIGIN INSERTION ACTION OF teres minor and teres major

teres minor: origin: lateral border of scapula insertion: posterior greater tubercle action: aDDuct and laterally rotate humerus innervation: axillary nerve

Teres Major: origin:lateral border of scapula insertion: crest of lesser tubercle action: ADDuct and medially rotate humerus innervation: brachial plexus

the top boney part is the spine of the scapula, based off that.. where is the infra spinatus?
