anatomy
provides framework of the body
skeletal system
largest bone in arm
humerous
chemical process by which cells receive nutrients for cell growth and reproduction
metabolism
generates new life to perpetuate the species
reproductive system
study of the function of organs and systems
physiology
non-striated muscles control what
automatic functions
lift up
levator
massage muscles from
insertion to origin
where is auricularis superior located
above ear
three parts of a muscle
origin, belly, insertion
muscle that raises eyebrows or draws the scalp forward
frontalis muscle
dense strong bands of fibrous tissue that connect the bones to each other
ligaments
non-moving portion of the muscle attached to bones or other fixed muscle
origin
midsection of the muscle
belly
muscle located at the nape of the neck and draws the scalp back
occipitalis
muscle- circles the eye socket and closes the eyelid
orbicularis oculi
located at the corner of the mouth, draws the mouth up and out, as in grinning
risorius
located above the eyelids, opens the eyelid
levator palpebrae superioris
located above and in front of the ear, opens and closes the jaw
temporalis
circles the mouth and contracts, puckers and wrinkles the lips, as in whistling
oris obicularis
located below the lower lip, pulls the lower lip down or to the side, expressing sarcasm
quadratus labii inferioris
bands of fibrous tissue that attack the muscle to the bones
tendons
located mid-forearm, straightens the fingers and wrist
extensor radialis
runs across the lower part of radius and ulna, turns palm downward and inward
pronator
lifts arm or turns it
deltoid
located between the eyes, draws brows down and wrinkles the area across the bridge of the nose
procerus
extends along the side of neck from ear to collarbone, moves head side to side and up and down
sternocleido mastoideus
located in the palm of hand, cause thumb to move toward the fingers, allowing to grasp or make fist
opponens
located under eyebrows, controls eyebrows drawing them in and downward
corrugator
upper chamber of heart
left and right atrium/auricle
red blood cells are also called
erythrocytes
red blood cells carry
oxygen and hemogloben
hemoglobin attracts oxygen molecules through a process called
oxygenation
controls the circulation of blood and lymph through the body
circulatory/vascular system
colorless gel-like substance that contains water, salt, and nutrients obtained from food
protoplasm
small vessels that take nutrients and oxygen from the arteries to the cells, takes waste products from the cells to the veins
capillaries
fluid part of the blood in which white and red blood cells and blood platelets are suspended
plasma
tubular, elastic, thin-walled branching vessels that carry oxygen-depleted blood from capillaries to the heart
veins
