which group of cavities make up the paranasal sinuses
frontal, sphenoidal, ethmoidal, maxillary
what is the function of the paranasal sinuses
provide resonance to the voice, shape to the face, and some degree of warmth and humidification to inspired air
what branches of nerves supply the paranasal sinuses
opthalmic, and maxillary nerves
abduction
moves a limb away from the midline
adduction
moves a limb towards the midline
extensor
increase the angle at a joint - extends a limb
flexor
decreases the angle at a joint - flexes a limb
pronator
turns a limb to face downwards
supinator
turns a limb to face upwards
rotator
rotates a limb
eversion
movement of the sole of the foot outward - laterally
inversion
movement of the sole of the foot inward - medially
which muscle raises the shoulder blade
levator scaulae

which muscle adducts/retracts scapula and rotates it inwards
rhomboid major
which muscle stabilizes scapula when hand exerts pressure on an object
serratus anterior
which muscle flexes, adducts and rotates arm medially
pectoralis major
which muscle depresses the shoulder and directs the scpula inferiorly and medially toward the thorax
pectoralis minor
which muscle extends, adducts and rotates arm medially; moves arm downward and backwards
latissimus dorsi
which muscle abducts, flexes, extends, and medially (anterior muscle) and laterally (posterior muscle) rotates the arm
deltoid
which muscle extends the arm, assists in adduction and medial rotation of the arm
teres major
which muscle flexes and supinates the forearm; flexes the arm
biceps brachii
which muscle flexes the forearm
brachialis
which muscle flexes, semi supinates and semi pronates the forearm
brachioradialis
which muscle extends the forearm
triceps brachii
which muscle pronates and flexes the forearm
pronator teres
which muscle pronates the forearm and the hand
pronator quadratus
which muscle supinates the forearm and hand
supinator
which muscle extends and adducts the hand and wrist
extensor carpi ulnaris
which muscle is a wrist flexor
palmaris longus
which muscle improves hand grip
palmaris brevis
what is the action of the triceps brachii
extends the elbow
what nerve is associated with the triceps brachii
radial nerve
what is the origin of extensor carpi ulnaris
lateral epicondyle of the humerus
what is the insertion for extensor carpi ulnaris
base of the 5th metacarpal via groove by ulnar styloid
what is the action of extensor carpi ulnaris
extends and adducts the hand at the wrist
what nerve is associated with the extensor carpi ulnaris
radial nerve
the medial epicondyle of the humerus is the origin of which two muscles
palmaris longus and pronator teres muscles
which muscle plantar flexes the foot and flexes the knee
gastrocnemius
which two muscles plantar flex the foot
soleus and plantaris
which muscle dosiflexes and inverts the foot
tibialis anterior
which muscle dorsiflexes and everts the foot
peroneus tertius
which muscle plantar flexes and inverts the foot
tibialis posterior
which2 muscles plantar flexe and evert the foot
peroneus longus & peroneus brevis

which muscle extends and rotates the thigh laterally
gluteus maximus
which muscle adducts, medially rotates and flexes the thigh
adductor longus
which muscle adducts, laterally rotates and flexes the thigh
adductor brevis
which muscle adducts, flexes, and laterally rotates and extends the thigh
adductor magnus
what muscle extends the lumbar region
iliocostalis lumborum
