8
What nerve innervates most in the anterior compartment of the forearm
median nerve
what muscle causes flexion at the wrist
flexor carpi radialis
what muscle causes flexion at the digits
flexor digitorum superficialis
what muscle causes pronation
pronator teres
how many muscles are in the posterior compartment of the forearm
12
What nerve innervates most in the posterior compartment of the forearm
the radial nerve
what muscle causes abduction of one digit (the pollux/thumb)
abductor pollicis longus
what muscle causes extension of the digits
extensor digitorum
what muscle causes extension of the wrist
extensor carpi ulnaris
What three muscles help with dorsiflexion (extension) of the leg in the anterior compartment
tibialis anterior
extensor hallucis longus
extensor digitorum longus
what four muscles help with plantar flexion (flexion) of the leg in the posterior compartment
gastrocnemius
flexor digitorum longus
tibialis posterior
flexor hallucis longus
what two muscles help with eversion in the lateral compartments of the leg
fibularis longus
fibularis brevis
what muscle work together to produce inversion in the lateral compartments of the leg
tibialis posterior and anterior
what part of the arm is the muscle biceps brachii located and what is it responsible for
anterior compartment
responsible for the flexion of elbow
what part of the arm is the muscle triceps brachii located and what is it responsible for
posterior compartment
responsible for extension at the elbow
what are the five most known nerves of the brachial plexus
axillary radial musculocutaneous median ulnar
what does the axillary nerve supply
the shoulder
what does the radial nerve supply
posterior arm and forearm
what does the musculocutaenous nerve supply
supplies the anterior arm
what does the median nerve supply
supplies the anterior forearm
and the hand but not as much as the ulnar
what does the ulnar nerve supply
supplies the hand
and the anterior forearm but not as much as the median nerve
what are the five muscles that move the shoulder
deltoid pectoralis major biceps brachii triceps brachii latissimus dorsi
what seven muscles move the hip
gluteus maximus gluteus medius & minimus piriformis short rotators psoas major iliacus
