General Terminology to Human Anatomy Flashcards
(33 cards)
Anatomy
study of the structure (what it looks like)
Physiology
study of the function (how it works)
Gross anatomy, Histology, Cytology
Level of anatomy: organs, tissues, cells
Evolution
focuses on similarities and differences in the body structures of different species
Level of Human Structure
Organism-organ system - organs- tissues- cells- organelles- molecules- atoms-particles
organ systems
a group of organs with a unique collective function
organs
carry out a particular function; have anatomical boundaries
tissues
mass of similar cells that perform a specific function
4 types of Tissues
epithelial, connective, nervous, muscular
cells
smallest unit of life; enclosed by a cell membrane
organelles
microscopic structures in a cell
molecules
smallest units of chemical compounds; have unique properties (h20)
Atoms
smallest pieces of matter
particles
not matter but building blocks of it (protons, neutrons, electrons)
Properties of a living Organism
- consist of a cell or cells
- organized a certain way so that the organism can perfrom certain task.
- irritablility/responsivness
Irritibility/Responsivness
sensing and reacting to stimuli
Metabolism
internal chemical changes with enzymes (synthesis, decomposition)
Homestasis
is the ability or tendency to maintain internal stability in an organism to compensate for environmental changes
Development
multiplication, growth, and differentiation through metabolism
Reproduction
produce offspring and pass genes on to the offspring
Homeostasis Process
nerves send a signal to the brain which releases an odor to maintain our body temperature
Positive Feedback
produce rapid change; self amplifying chain of events Ex. childbirth
Sagittal Plane
divide the body/organ into right and left position
frontal (coronal) plane
divide the body/organ into anterior and posterior
