Introduction: Part 1 Flashcards
The study of the internal and external structures of the human body.
Anatomy
The study of the function of the structures of the human body.
Physiology
The area of anatomy the focuses on the visible features of the body.
Gross anatomy
The three levels of gross anatomy are:
surface, regional, and systemic
The area of anatomy that focuses on the features not visible with the unaided eye.
Microscopic anatomy
This level of physiology focuses on the molecular functions.
Cell
This level of physiology focuses on the function of specific organs.
Special
This level of physiology focuses on the function of organ system.
Systemic
This level of physiology focuses on diseases.
Pathology
This is the first level of organization of the human body
Chemical
This is the second level of organization of the human body
Cellular
This is the third level of organization of the human body
Tissue
This is the fourth level of organization of the human body
Organ
This is the fifth level of organization of the human body.
Organ system
This is the final level of organization of the human body
Organism
The smallest living unit
Cell
Similar cells working together
Tissue
Two or more different tissues performing a specific function.
Organ
Interaction of organs
Organ system
Organ systems working together
Organism
The process of a living thing maintaining a relatively stable internal environment
Homeostasis
The three “steps” of homeostasis
Receptor, Control Center, and Effector
This is sensitive to a change or stimulus
Receptor
This receives information
Control Center
This responds to the commands of the control center and will either oppose or reinforce the stimulus.
Effector
This happens when homeostasis fails
Sickness (illness)
Study that analyzes specific cells
Cytology
Study that examines tissues
Histology
This is when a response reinforces a stimulus to maintain homeostasis.
Positive feedback
This is when a response opposes a stimulus to maintain homeostasis
Negative feedback
