Human Organism Flashcards
investigates the structure of the body
anatomy
what does the word “anatomy” mean?
to dissect, or cut apart and separate the parts of the body for study
examines the relationship between the structure of a body part and its function
anatomy
two basic approach to study anatomy
systematic and regional anatomy
it is the study of the body by system, such as the cardiovascular, nervous, skeletal and muscular
systematic anatomy
it is the organization of the body by areas
regional anatomy
two general ways to examine the internal structures of a living person
surface anatomy and anatomical imaging
studies the external features
surface anatomy
involves the use of x-ray, MRI, and other technologies to create pictures of internal structures
anatomical imaging
deals with the process or functions of living things
physiology
two major goals in physiology
1) examining the body’s response to stimuli
2) examining the body’s maintenance of stable internal conditions
study of humans
human physiology
focuses on processes inside cells such as the manufacturing of substances
cellular physiology
focuses on the function of organ systems
systematic physiology
Level of organization for the human body
1) chemical level
2) cell level
3) tissue level
4) organ level
5) organ system level
6) organism level
involves how atoms interact and combine into molecules
chemical level
basic structural and functions units of organisms
cell
carries out particular functions, includes digestion and movement for cell
organelles
group of similar cells and the materials surrounding them
tissue
four primary types of tissues
- epithelial
- connective
- muscle
- nervous
composed of two or more tissue types that together perform one or more common functions
organ
group of organs that together perform a common function or set of functions
organ systems
11 major organ systems
- integumentary
- skeletal
- nervous
- muscular
- endocrine
- respiratory
- digestive
- lymphatic
- cardiovascular
- reproductive
any living thing considered as a whole
organism
the six characteristics of life
- organization
- metabolism
- responsiveness
- growth
- development
- reproduction
specific interrelationships among the individual parts on an organism
organization
use energy to perform other vital functions, such as growth, movements and reproduction
metabolism
ability to sense changes in the external or internal environment and adjust to those changes
responsiveness
increase in the size or number of cells, which produces an overall enlargement
growth
changes an organism undergoes through time
development
changes in a cell’s structure and function
differentiation
formation of new cells or new organisms
reproduction
it is the maintenance of a relatively constant environment within the body
homeostasis
deviation from the set point is made smaller or is resisted
negative feedback
maintains variation within a normal range
negative feedback
monitors the value of a variable by detecting stimuli
receptors
determines the set point for the variable and receives input from the receptor about the variable
control center
adjust the value of the variable when directed by the control center
effector
change variable
stimulus
most anatomical terms are derived from what language
Greek or latin
person standing upright with face directed forward, the limbs hanging to the sides, and the palms of the hands facing forward
anatomical position
lying face upward
supine
lying face downward
prone
above
superior
below
inferior
in front of
anterior
behind
posterior
to the front of the body
anterior or ventral
the back of the body
posterior or dorsal
close to
proximal
far from
distal
away from the surface
deep
toward or on the surface
superficial
toward the midline
medial
away from the midline
lateral
