Lecture 1 Flashcards
Biology
The study of life
Anatomy
The study of the structures of the body.
- What they are made of
- Where they are located
- Associated structures
Physiology
The study of the normal function of anatomical structures
Pathology
The study of abnormal or diseased physiology
Gross Anatomy (Macro Anatomy)
Examination of large structures without the aid of magnification
Micro Anatomy
Examination of structures that are only visible with the aid of magnification
- Cells
- Molecules
Cytology
Study of cells and their structures
Histology
Study of tissues and their structures
Physiological Levels of Organization
Atoms>Molecules>Cells>Tissues>Organs>Organisms
Atoms
The smallest stable unit of structure
Molecules
Group of atoms that work together
Cells
Group of molecules that work together
Tissue
A group of similar cells that work together
Organ
A group of tissues of similar structure and function
Responsiveness
The ability of the body to respond, in a normal way, to external and internal changes in the environment
Adaptation
The ability to adapt to situations and environments
Growth
maturation of all living things toward reproduction
Metabolism
Chemical reactions that occur within the body
Excretion
Elimination of waste products of metabolization
Developmental Anatomy
Study of structure from conception to birth
Regional Anatomy
Study of specific functions or areas of the body
Homeostasis
All body systems working together to maintain a stable internal environment.
State of equilibrium to function and structure such as body temperature, fluid volume, fluid composition, waste product concentration, blood pressure.
What are the 4 categories of tissues?
Epitheleal
Connective
Muscle
Nerve
Negative Feedback
A response to negate a stimulus so the body can be brought back into homeostasis
