elbow extensors
Triceps brachii
functions of gluteus maximus?
hip extensor
hip lateral rotators
extensors of the shoulder must cross the joint on which aspect?
posterior
the ulnar collateral ligament of the elbow restricts which movement of the elbow?
abduction
which movements are normally performed at the wrist joint?
flexion/extension
adduction/abduction
which of these muscles medially rotates the shoulder?
pectorialis major anterior deltoid subscapularis latissimus dorsi teres major
which of these muscles supinates the forearm?
supinator
biceps brachii
where does eversion/inversion occur?
subtalar joint
ankle joint has NO movement in coronal plane
which movements are normally performed at the ankle joint?
dorsiflexion/plantarflexion
**only movement that occurs here
which muscles flex the knee? **
biceps femoris semitendinosus semimembranosis sartorius gracilis
the 3 lateral ligaments of the ankle ALL attach to which bone?
fibula
- none attach to tibia, 2 attach to calcaneus and 1 to the talus
which of these bones is a tarsal bone?
cuboid
navicular
where are carpels located?
hand
which muscle laterally rotates hip?
piriformis
gluteus maximus
on the humerus how do you tell the medial side from the lateral?
the olecranon fossa
what area of the femur does the patella attach to?
trochlea
what aspect of the elbow joint stops adduction?
radial collateral ligaments
what aspect of the elbow joint stops aBduction?
ulnar collateral ligament
describe the positioning of the anterior and posterior cruciate ligaments:
anterior cruciate crosses through the joint
posterior is simply at the back of the tibia - intercondylar notch
what are the flexors of the knee?
hamstrings: biceps femoris, semitendinosus and semimembranous
sartorius and gracilis also help
the extensors of the knee?
rectus femoris
vasta lateralis
vasta medialis
vasta intermedius
what are the medial rotators of the knee?
sartorius, semimembranosus, semitendinosus, popliteus
lateral rotators of the knee?
biceps femoris
forearm supinators:
supinator, biceps brachii
forearm pronators?
pronator teres, pronator quadratus
describe the location of pronator teres?
near elbow joint - medial epicondyle
describe the location of pronator quadratus:
squarish looking muscle near the wrist
works with pronator teres to pronate wrist
what are the functions of pectoralis major?
medial rotation of shoulder
adduction of shoulder
flexion of shoulder
what is the functions of latissimus dorsi?
Medial rotation of shoulder
extension of shoulder
adduction of shoulder
what common features do pectoralis major and latissimus dorsi share?
both pass directly from trunk to the humerus
bypass scapula
what is special about the deltoid and gluteus maximus muscle?
can move their respective joints in opposite directions in the same plane
deltoid - flex and extend the shoulder
gluteus medius - medial and lateral rotation
BOTH wrap around shoulder/hip joint to act in both directions in the same plane
how do you remember the bones of the hand?
SLTPTTCH
Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate
what are the medial ligaments of the ankle?
the deltoid! 3 parts(do not need to know) anterior tibiotular posterior tibiotular tibiocalcaneal
