TERM DEFINITION
Anatomy
Study of structure and shape of body and body parts and relationship to one another
Physiology
Study of how the body and its parts work or function
Atoms
Building blocks of matter
Cells
Smallest units of all living things
Tissues
Groups of similar cells that have a common function
Organ
Structure that is composed of two or more tissue types and performs specific function for the body
Organ system
Group of organs that cooperate to accomplish a common purpose
Organism
Highest level of structural organization; made up of the 11 organ systems
Necessary life functions
Maintenance of boundaries movement responsiveness digestion metabolism excretion reproduction growth
Survival needs
Nutrients oxygen water constant body temperature constant atmospheric pressure
Homeostasis
Body�s ability to maintain relatively stable internal conditions in response to environmental changes. A dynamic state of equilibrium results.
Components of a homeostatic control mechanism
Receptor
Negative feedback mechanisms Net effect of the response to the stimulus is
to shut off the original stimulus or reduce
its intensity
Positive feedback mechanisms Increase the original disturbance/stimulus
and to push the variable farther from its
original value

Superior Toward head or upper part of a structure or
the body; above; also known as cranial or
cephalad
Inferior Away from the head end or toward the
lower part of a structure or the body;
below; also known as caudal
Anterior Toward or at the front of the body; in front
of
Posterior Toward or at the backside of the body;
behind
Medial Toward or at the midline of the body; on
the inner side of
Lateral Away from the midline of the body; on the
outer side of
Intermediate Between a more medial and a more lateral
structure
Proximal Close to the origin of the body part or the
point of attachment of a limb to the body
trunk
Distal Farther from the origin of a body part or
the point of attachment of a limb to the
body trunk
Superficial Toward or at the body surface; external
Deep Away from the body surface; more internal
Sagittal section Cut made along a lengthwise plane or
longitudinal plane of the body
dividing the
body into left and right body parts
Midsagittal/median section Cut down median plane and right and left
parts are equal in size
Parasagittal A sagittal section that is not on the medial
plane
Frontal/coronal section Cut made along a lengthwise plane that
divides the body or organ into anterior and
posterior parts
Transverse/cross section Cut made along a horizontal plane dividing
body or organ into superior and inferior
parts
Dorsal body cavity Two subdivisions; cranial cavity and spinal
cavity
Ventral body cavity Two subdivisions; thoracic and
abdominopelvic cavity
separated by
diaphragm
Umbilical region (abdominopelvic cavity) Centermost region deep to and surrounding

Integumentary system organs Skin
Integumentary system functions Forms external body covering; protects
deeper tissue from injury; waterproofs;
regulates body temp; vitamin D synthesis;
some waste excretion
Skeletal system organs Bones
cartilages
Skeletal system functions Protects and supports body organs;
provides a framework the muscles use to
cause movement; hematopoesis; mineral
storage
Muscular system organs Skeletal muscles
Muscular system functions Contract/shorten for movement
maintain
posture
heat generation
Nervous system organs Brain
spinal cord
receptors
Nervous system functions Fast acting control/communication system
of body; responds to internal/external
changes by activating appropriate muscles/
glands through nerve impulses
Endocrine system organs Pituitary
thyroid
thymus
pancreas
Endocrine system functions Slow acting control/communication system
of the body; glands secrete hormones that
regulate routine processes as growth
reproduction
and nutrient use
Cardiovascular system organs Heart and blood vessels
Cardiovascular system functions Carries oxygen
nutrients
metabolic waste products (in blood)
Lymphatic system organs Lymphatic vessels
lymph nodes
tonsils
Lymphatic system functions Complementary to cardiovascular system;
carries leaked fluid from blood vessels and
returns it to blood
disposes of debris
immune surveillance
Respiratory system organs Nasal passages
pharynx
