Definitions
The study of the structure and shape of the body and its parts.
What is Anatomy?
The ability to sense and react.
What is responsiveness (irritability)?
Standing erect with feet parallel and arms hanging at the sidew with palms facing forward and thumbs pointing away from the body.
What is anatomical position?
Maintenance of a relatively stable internal condition necessary for normal body functioning and sustaining life.
What is homeostasis?
The number of cells in the human body.
What is 50-100 trillion?
The four tissue types,
What are epithelial, muscle, nervous, and connective tissues?
The study of how the body and its parts work or function.
What is Physiology?
What is metabolism?
The plane the sternum divides the body.
What is median or midsagittal plane?
The three components of homeostasis.
What are receptors, control center, and effectors?
The three regions of a cell.
What are plasma membrane, nucleus, and cytoplasm?
This tissue is avascular (no blood supply).
What is cartilage?
The structural unit of all living things.
What is the cell?
Removes wastes from metabolism.
What is excretion?
The plane the diaphragm divides the body along.
What is the traverse plane?
What is the control center?
The major cell of cartilage.
What is the chondrocyte?
Tissue type of tendons, ligaments, and the dermis.
What is dense connective tissue?
Decrease in side of a tissue or organ occurs when the organ is no longer stimulated normally.
What is atrophy?
Amount of water the body is made up of as a percentage.
What is 60-80%?
Cavity that contains the eyeball.
What is the orbital cavity?
Provides a means for response to the stimulus along an efferent pathway.
What is effector?
Impermeable and binds cells together into leak proof sheets like a zipper.
What are tight junctions?
An areolar tissue where fat cells dominate.
What is adipose tissue?
Increase in side of muscle tissue or organ may occur when tissue is strongly stimulated or irritated.
What is hyperplasia?
Nutrients, oxygen, water, normal body temperature, atmospheric pressure.
What are survival needs?
Plane that divides the anterior body from the posterior body.
What is the frontal plane?
Responds to changes in the environment (stimuli) and sends information to the control center.
What is the receptor?
Communicating junctions made of hollow cylinders of proteins (connexions) that span the width of the adjacent membrane channels.
What are gap junctions?
This tissue type is insulated, supported, and protected by neuroglia, is irritable and conductive, and makes up the brain, spinal cord, and nerves?
What is nervous tissue?
