HUBS Lecture 10 pt2 Flashcards
muscle groups (44 cards)
what is the origin of the biceps brachii
the scapula
what is the insertion of the biceps brachii
radial tuberosity
what movements is the biceps brachii involved in
shoulder - flexion - anterior
elbow - flexion - anterior
radio ulnar joints - supination (not pronation)
what is an origin
the point where bone meets muscle that is proximal to the joint
what are the origins of the triceps brachii
the scapula (1 attachment)
the humerus (2 attachments)
what is the insertion of the triceps brachii
olecranon process of the ulna
what movements is the triceps brachii involved in
shoulder - extension - posterior
elbow - extension - posterior
(not pronation and supination because the ulna doesn’t move with pronation and supination)
what are the origins of the deltoid
scapula and clavicle
what is the insertion of the deltoid
the deltoid tuberosity - part way down your humerus laterally
what movements is the deltoid involved in - remember it is a multi pennate muscle
shoulder - flexion (anterior fibres)
- abduction (lateral fibres) - extension (posterior fibres)
what 2 muscles make up iliopsos
psoas major and iliacus
what is the origin of psoas major
lumbar vertebrae
what is the insertion of psoas major
femur
what movements is psoas major involved in
hip - flexion - anterior
what is the origin of iliacus
iliac fossa
what is the insertion of iliacus
femur
what movement is iliacus involved in
hip - flexion - anterior
what are the origins of gluteus Maximus
the ilium and sacrum
what is the insertion of gluteus Maximus
femur
what movement is gluteus Maximus involved in
hip - extension - posterior
what is the origin of rectus femoris
ilium
what is the insertion of rectus femoris
tibial tuberosity
what movements is rectus femoris involved in
hip - flexion - anterior
knee - extension - anterior
what is the origin of the vastus muscles
femur
