HUBS Lecture 10 pt2 Flashcards
muscle groups
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
what is the insertion of the vastus muscles
tibial tuberosity
what 4 muscles make up quadriceps femoris group
rectus femoris, vastus lateralis, vastus intermedius and vastus medialis
what movements are the vastus muscles involved in
knee - extension - anterior
what 3 muscles make up the hamstrings
biceps femoris, semi-membranosus
and semi-tendinous
what are the origins of biceps femoris
ischium and femur
what is the insertion of biceps femoris
fibula
what movements is the biceps femoris involved in
hip - extension - posterior
knee - flexion - posterior
knee - rotation when flexed
what is the origin of semi-membranosus and semi-tendinosus
ischium
what is the insertion of semi-membranosus and semi-tendinosus
tibia
what movements are semi-membranosus and semi-tendinosus involved in
hip - extension - posterior
knee - flexion - posterior
knee - rotation when flexed
what is the origin of the tibialis anterior
tibia
what is the insertion of tibialis anterior
tarsals
what movements is tibialis anterior involved in
ankle - dorsiflexion and eversion
what muscles make up the triceps surae group
gastrocnemius and soleus
what is the origin of gastrocnemius
the condyles of the femur
what is the insertion of gastrocnemius
calcaneus via the calcaneal/achillies tendon
what movements is gastrocnemius involved in
knee - flexion - posterior
ankle - plantar flexion
what is the origin of soleus
tibia and fibula
what is the insertion of soleus
calcaneus via the calcaneal/achillies tendon
what movement is soleus involved in
ankle - plantar flexion
