Chapter 1 Flashcards
Define Anatomy
The study of body structures and the relationships among them.
Define Physiology
The study of body functions and how the body parts work.
Define Cell Biology
Cellular Structure and Functions.
Define Histology
Microscopic structure of tissues
Define Gross Anatomy
Structures that can be examined without a microscope
Define Systemic anatomy
Structure of specific systems of the body such as the nervous or respiratory systems.
Define Regional anatomy
Specific regions of the body such as the head or chest.
Define Surface (topographical) anatomy
Surface markings of the body to understand internal anatomy through visualization and palpation.
What are the Levels of structural organization from smallest to biggest?
- Chemical Level
- Cellular Level.
- Tissue Level.
- Organ Level.
- System level (Organ System)
- Organism Level.
What causes more interstitial fluid?
The faster the blood flow is, the more interstitial fluid there is.
What are the basic life processes that distinguish living things from nonliving things?
- Metabolism
- Responsiveness
- Movement
- Growth
- Differentiation
- Reproduction
What are the two phases of metabolism?
Catabolism- breakdown of complex chemical substances into simpler components.
Anabolism- Building up of complex chemical substances from smaller, simpler components.
What is Homeostasis?
a condition of equilibrium or balance in the body’s internal environment.
What are the types of fluid that remain outside of the body cells?
Extracellular Fluid:
1. Interstitial fluid
2. Blood plasma.
3. Lymph.
4. Cerebrospinal fluid.
5. Synovial fluid.
6. Aqueous humor and vitreous humor.
How is Homeostasis controlled?
The nervous system regulates homeostasis by sending nerve impulses to organs that can counteract changes from the balanced state. The endocrine system secretes hormones into the blood.
What’s needed for a feedback loop?
- A receptor- body structure that monitors changes in a controlled condition and sends input to a control center.
- Control center- the brain, receives input and provides nerve impulses to effectors.
- body structure that receives output from the control center and produces a response
What is the main difference between negative and positive feedback loops?
Negative- Reverses a change in controlled condition.
Positive- reinforce a change in one of the body-controlled conditions.
What is the name of the position when a body is lying facedown?
prone position
What is the name of the position when a body is lying face up?
supine position
