Anatomy
The study of structure
Physiology
The study of function
Gross anatomy
Looks at large structures with the unaided eye
What is microsopic anatomy
study small structures using a microscope
What is developmental anatomy?
The study of changes from birth to death of an organism
What is cytology?
The study of cells
What is histology
The study of tissues
What is molecule?
A particle composed of at least two atoms ( the smallest particles with unique chemical identities)
What is metabolism?
The sum of the chemical change from taking in molecules forom the environment and chemically change them into molecules that form their own structures, control their physiology, or provide them with energy.
What is catabolic
breaks large molecules into small ones
What is anabolic
builds large molecule form smaller ones
What is stimuli
Changes in the environment
What is body cavity
fluid filled space instide the body that holds and protects internal organs
What is serosa (serous membrane)?
Membranes lining closed internal body cavities
What is serous fluid?
A watery fluid, resembling (blood-) serum
What is regional anatomy?
Study structures by region. They are physically related because they are close together
What is systemic anatomy
study structures by system. They are functionally related because the work together to perform the same function
What is surface anatomy?
the study of internal structure in the context of external markings. or seeing how the internal structs effects the external appearance.
What is the difference between surface anatomy, regional anatomy, and systemic anatomy
Regional anatomy is the study of physically related structures while the systemic anatomy is the study of functionally related structures. Surface study the internal structures and see how it effects the external appearance.
Explain the “principle of complementary of structure and function” in relation to A&P
The way an object is built (its structure) allows for it to achieve (it complements) the objects special purpose (its function)
What are the 7 levels of organization (from simplest to the most complex) give examples
• chemical (like atoms and molecules • organells (nucleus and mictochondira • cellular (fibrous • tissue (muscle) • Organ (heart) • system (digestive) • Organism (human)
What makes up an organelle? what is an organelle
a group of chemicals, organelles are little “organs” inside cells that have specific functions
What makes up the cellar level? What is the smallest unit of life
a group of organelle form a cell (which is the smallest unit of life)
What makes up the tissue level? what is a tissue
a group of cells, the groups of cells work together to perform a specific function
