Introduction to the Human Body
The science that studies the form and composition of structures of the body
What is Anatomy?
The homeostatic mechanism that tends to stabilize an upset in the body’s physiological condition by preventing an excessive response to a stimulus.
What is Negative Feedback?
The movement of molecules in response to concentration gradients.
What is a Gradient?
Describes the middle or direction toward the midline of the body.
What is Medial?
An organized unit of a type of cells that have a similar structure and that work together to perform a specific function.
What is Tissue?
The science that studies the functioning of the body structures including their relevant chemistry, biochemistry, and physics.
What is Physiology?
The ideal value or narrow range for a physiological parameter
What is a Setpoint?
A living being composed of one or more cells that can independently perform all physiologic functions necessary for life
What is an organism?
Describes a position nearer to the surface of the body.
What is superficial?
One of the pigments found in the skin; determines the color of hair and skin and protects cells from UV radiation damage.
What is Melanin?
The approach to studying the structures of the body that considers all of the structures found near each other at the same time
What is Regional Anatomy?
The dynamic state of stable internal conditions within the body systems that living organisms maintain
What is Homeostasis?
The tiny functioning units within a cell.
What are Organelles?
Describes direction toward the back of the body.
What is Posterior?
The region in the center of the thoracic cage, between the lungs, where the heart sits.
The study of larger structures of the body that can be seen with the naked eye
What is Gross Anatomy?
The mechanism that intensifies a change in the body’s physiological condition in response to a stimulus.
What is Positive Feedback?
A functionally distinct structure composed of two or more types of tissues.
What is an organ?
Describes a position above or closer to the head.
What is Superior?
Serous membrane that lines the pleural cavity and covers the lungs.
What is Pleura?
The approach to studying the structures of the body that considers all of the structures within an organ system at one time.
What is Systemic Anatomy?
Portion of the dorsal cavity containing the spinal cord.
What is the Spinal Cavity?
The smallest independently functioning unit of all organisms; in animals, a cell contains cytoplasm, composed of fluid and organelles
What is the Cell?
Anterior side of the body down so that the posterior is viewable/up.
What is Prone?
Describes the position of a structure on a limb farther from the point of attachment or the trunk of the body.
What is Distal?
