cell

the smallest living unit in the body

tissue

many cells and some surrounding material

e.g. epithelial, muscular, neural, and connective

organ

combination of tissues

organ system

combination of various organs make up a specific system

organism

humans are composed of 11 organ systems

integumentary system major functions

protection from environmental hazards, temperature controland sensory reception.

skeletal system main functions

support, protection of soft tissues, mineral storage, blood formation

muscular system main functions

locomotion, support, heat production

nervous system main functions

directing immediate responses to stimuli, usually by coordinating the activities of other organ systems

anatomical position

standing with feet flat on the floor facing forward

eyes are straight ahead

hands are at the side, palms are facing forward

supine

lying down, face up, in the anatomical position

prone

lying down, face down, in the anatomical position

superior also means

cephalad for humans, dorsal for dogs

anterior also means

ventral for humans, cephalad for dogs

posterior also means

dorsal for humans, caudal for dogs

frontal plane

divides the body into the front and back

transverse plane

divides the body into the top and bottom

total magnification

ocular (10x) x objective

field of view

area seen through the oculars

parcentral

the area in the center of view is what you see when you move from low to higher power objective

parfocal

the part of slide in focus at lower power is still in focus at higher power

depth of view

amount of image that you can view while in focus

can change it by changing iris aperture diaphragm setting
