6 - compartments Flashcards
anterior arm is innervated by
musculocutaneus
muscles in the anterior arm
coracobrachialis, brachialis, biceps brachii
coracobrachialis
from coracoid process on the scapula and attatches at the brachium
brachialis
originates from the brachium
starts when coracobrachialis finishes, inserts into the ulnar tuberosity
biceps brachii
has two heads - both start at scapula
first one starts at coracoid process
other one starts at supraglenoid tubercle
combines into one muscle
action of the anterior arm
flexion
a degree of adduction and internal rotation as well
innervation of posterior arm
radial nerve
innervation of brachialis
musculocutaneous
action of the posterior arm
triceps brachii
triceps brachii
three heads
common insertion in the olecranon process
only head to cross the glenohumeral joint
long head f triceps brachii
heads of the triceps brachii
medial lateral and long
muscles forming boundary of the quadrangular space
lng head of triceps brachii
teres major and minor
surgical neck of the humerous
which nerve goes through the quadrangular space
axillar nerve
anterior forarm is supplied by
the median nerve
ulnar innervates part of the flexor digitorum profundus
action at the anterior forearm
flexion
superficial muscles of the anterior forearm
pronator teres flexor carpi radialis palmaris longus flexor digitorum superficialis flexor carpi ulnaris
pronator teres
flexes the elbow and also pronates the elbow
flexor carpi radialis
inserts into the metacarpals
flexor of the carpis on the radial side
palmaris longus
inserts into the fascia of the palm
small muscle - may not be there at all
deep muscles of tthe anterior forearm
pronator quadratus
flexor pollicis longus
flexor digitorum profundus
flexor digitorum superficialis
gives off tendons into the hand
does not cross distal phalangeal joint - can only flex proximal phalangeal
flexor carpi ulnaris
flexes the carpal joints at the ulnar side
pronator quadratus
quadrangualar shape forforming pronation at the distal forearm
flexor pollicis longus
runs through the carpal tunnel and along the ventral aspects of the thumb
flexor digitorum profundus
passes deep and distal to the flexor digitorum superficialis to cross dristal interphalanges and perform flexion
nerve innervation of the posterior forearm
radial nerve
superficial muscles of the posterior forearm
extensor carpi ulnaris extensor digiti minimi extensor digitorum extensor carpi radialis brevis extensor carpi radialis longus brachioradialis
action of the posterior forearm
extension
extensor carpi ulnaris
travels down the ulnar side an inserts into the carpis at the ulnar side
extensor digiti minimi
alongside the extensor carrpi ulnaris
inserts
extensor digitorum
inserts into digits 2-5
no superficial and deep
extensor carpi radialis brevis and longus
do the same thing
brachioradialis
starts at the supracondylar ridge
crosses ventrally to the elbow
dorsal muscle that performs flexion
doesnt cross the wrist
deep muscles of the posterior forearm
supinator adductor pollicis longus extensor pollicis brevis extensor pollicis loongus extensor indicus
supinator
origin from the olecranon process
wraps around the radius onto the front of the radius
abductor pollicis longus
thumb adducts in sagittal plane
extensor pollicis brevis
cannot flex at the ditsal joint
extensor pollicis longus
goes to the distal joint
anterior thigh is innervated by
femoral nerve
anterior thigh is
dorsal
action at the anterior thigh
extensin at the knee
quadriceps muscles
vastus lateralis
vastus medialis
vastus intermedius
rectus femoris
muslces of the anterior thigh
vastus lateralis vastus medialis vastus intermedius rectus femoris sartrius iliacus psoas
vastus intermedius
shiny
sartorius
thin and long
iliacus
the muscle filling the iliac fossa
lateral thigh is supplied by
gluteals
muscles of the lateral thigh perfomring abduction
gluteus medius
gluteus minimus
tensor facia lata
muscles at the lateral thigh performing extension
gluteus maximus
biceps femoris short head
abductor muscles at the lateral thigh are supplied by
superior gluteal
gluteus maximus is suppied by
inferior gluteal
biceps femoris is supplied by
common fibular nerve
action of the medial thigh
flexion and adduction
muscles originating from the pubis/ischium
ventral
muscles originating frm the ileum
dorsal
nerve innervating the medial thigh
obturator
muscles of the medial thigh
pectineus adductor magnus adductor brevis gracilis adductor magnus
posterior thigh supplied by
tibial
muscles at the posterior thiggh
hamstrings biceps femoris short head adductor magnus sartorius gracilis semitendonosis
hamstrings
semitendonsis semimembranosous biceps femoris (lng head only)
what makes it a hamstring
tibial nerve innervation
biceps femoris shorthead innervated by
cmmon fibular
anterior and lateral leg innervated by
fibular nerve
lateral compartment of the leg innervated by
superficial fibular nerve
anterior cmpartment of the leg innervated by
deep fibular nerve
muscles of the lateral compartment of the leg
fibularis brevis
fibularis longus
muscles of the anterior compartment of the leg
