Intro to anaphy Flashcards
investigates the structure of the body
ANATOMY
to dissect or cut apart and separate , the parts of the body for study
anatomy
2 basic approaches to the study of anatomy
- systematic anatomy
- regional anatomy
study of the body by systems
systematic anatomy
study of the organization of the body by areas
regional anatomy
2 general ways to examine internal structures
- surface anatomy
- anatomical imaging
study of external features or bony projections which serve to locate deeper structures.
surface anatomy
involves the use of imaging modalities such as x-rays, ultrasound, CT-scan, MRI, etc.
anatomical imaging
deals with the processses or functions of living thing
physiology
major goals of physiology (2)
- understand and predict the body’s responses to stimuli
- understand how the body maintains conditions in the presence of continually changing internal and external environments.
Structural and functional organization of the human body (6)
- Chemical level
- cell level
- tissue level
- organ level
- organ system level
- organism
Structural and functional organization of the human body
The structural and functional characteristics of all organisms are determined by their chemical makeup.
chemical level
Structural and functional organization of the human body
____ are the basic structural and functional units of organisms such as plants and animals. They contain organelles that carry out particular functions such as digestion, and movement for the cell.
Cell level
Structural and functional organization of the human body
_____ is a group of similar cells and the materials that surround them.
tissue level
Structural and functional organization of the human body
an ___ is composed of two or more tissue types that together perform one or more common functions.
organ level
Structural and functional organization of the human body
An ___ ___ is a group of organs that together perform a common function or set of functions.
organ system
Structural and functional organization of the human body
an ___ is any living thing considered as a whole. The human ____ is a network of organ systems that are mutually dependent upon one another.
organism level
Characteristics of life (6)
- organization
- metabolism
- responsiveness
- growth
- development
- reproduction
Characteristics of Life
specific interrelationships among the individual parts of an organism, and how those parts interact to perform specific functions.
Organization
Characteristics of Life
- the ability to use energy to perform other vital functions
- Human cells possess specialized proteins that can break down food molectules to use as a source of energy
metabolism
Characteristics of Life
an organism’s to sense changes in the external or internal environment and adjust to those changes.
responsiveness
Characteristics of Life
increase in the size or number of cells, ehich produces an overall enlargement.
growth
Characteristics of Life
changes an organism undergoes through time, beginning with fertilization snd ending at death.
development
Characteristics of Life
Development: __________ involves changes in a cell’s structure and function from an immature, generalized state to a mature. specialized state.
differentiation
Characteristics of Life
formation of new cells or new organisms
reproduction
maintenance of a relative constant environment within the body.
homeostasis
- narrow range of conditions
- changes in body conditions ex. temp, volume, chemical content
variables
__ mechanisms are mostly governed by nervous and endocrine system
homeostatic mechanisms
a change variable is a ___ because it initiates homeostatic mechanisms
stimulus
Most sytems of the body are regulated by ________
negative feedback mechanisms
- deviation from set point is made smaller or resisted.
- reverses the change
negative feedback
activation of one component leads to inactivation of another
negative feedback
3 components of negative feedback
- receptor
- control center
- effector
3 components of negative feedback
- monitors the value of the variable
- detects stimuli
receptor
3 components of negative feedback
establishes the set point around which the variable is maintained.
control center
3 components of negative feedback
can change the value of the variable
effector
