A&P Basics
This is the study of the structure of the body, answering the question "what are the parts?
What is Anatomy?
The simplest level of organization where atoms combine to form molecules.
What is the Chemical level?
The body's ability to maintain relatively stable internal conditions despite continuous changes in the outside world.
What is Homeostasis?
The standard reference body position where the body is erect, feet slightly apart, and palms face forward.
What is the Anatomical Position?
The body cavity subdivision that contains the brain and the spinal cord.
What is the Dorsal Cavity?
This is the study of the function of the body, answering the question "how do the parts work?".
What is Physiology?
A group of similar cells working together to perform a common function constitutes this level.
What is the Tissue level?
The physiological state where the internal environment is disturbed to the point that disease occurs
What is Homeostatic Imbalance?
The directional term for a part of the body that is closer to the midline.
What is Medial?
The body cavity that houses the heart and lungs, superior to the diaphragm.
What is the Thoracic Cavity?
This subdivision of anatomy studies structures that can be seen with the naked eye.
What is Gross Anatomy?
At this level, two or more different tissues work together to perform a specific function (e.g., the stomach or a blood vessel).
What is the Organ level?
The most common type of feedback mechanism in the body, which causes the response to be opposite of the initial stimulus (e.g., sweating when hot).
What is Negative Feedback?
The directional term that means further from the point of attachment or the body trunk, such as the fingers relative to the elbow.
What is Distal?
The general term for the thin, double-layered membrane that lines the walls of the ventral cavity (parietal) and covers the organs (visceral).
What is a Serous Membrane?
The subdivision of microscopic anatomy that is the study of tissues
What is Histology?
These are the two organ systems that primarily control and maintain homeostasis.
What are the Nervous System and Endocrine System?
The less common feedback mechanism that causes the response to continue in the same direction as the initial change, such as labor contractions or blood clotting.
What is Positive Feedback
This plane divides the body vertically into right and left parts.
What is the Sagittal plane?
The small space between the two serous layers that is filled with fluid
What is the Serous Cavity?
The body division that includes the head, neck, and trunk
What is the Axial division?
The correct sequence from least to most complex: molecules, cells, tissues, organs, organ systems, and this.
What is the Organismal level?
According to the "Rule of Threes" for survival, the maximum time a human can go without air/oxygen.
What are Three MINUTES?
The body plane that divides the body into superior (top) and inferior (bottom) sections, often called a cross-section.
What is the Transverse (or Horizontal) plane?
The four regions of the abdominopelvic cavity used by clinicians to easily locate pain or organs.
What are the Right Upper, Left Upper, Right Lower, and Left Lower Quadrants?
