TEST 2 Flashcards
(60 cards)
What is the study of the structure of an organism and the
relationships of its parts?
Anatomy
What is the study of the functions of living organisms and
their parts.
Physiology
What are the smallest “living” units of structure and
function found in the human body?
cells
What is the part of the scientific method used to ensure
that the test situation is not affecting the results?
experimental control
The dorsal cavities that house the brain and the spinal
cord are?
the cranial cavity (for the brain) and the spinal cavity (for the spinal cord)
The plane of the body that divides the body or any of its
parts into front and back portions is called?
Frontal Plane
The activation of platelets to become increasingly sticky in
response to damage to a blood vessel is an example of
what type of feedback loop?
Positive Feedback Loop
The excretion of larger than usual volumes of urine when
the volume of fluid in the body is greater than the normal,
ideal amount, is an example of what type of feedback
loop?
Negative Feedback Loop
What is the unique type of sagittal plane in the body that
divides the body into two equal halves.
Midsaggital Plane
There are four abdominopelevic quadrants in the body.
Which quadrant is the stomach found in?
left upper quadrant
The position of the body in which the body is positioned
with the face down is known as?
Prone Position
The position of the body in which the body is in an erect or
standing posture with the arms at the sides and the palms
turned forward; head forward; feet forward and aligned at
the toe is called?
Anatomical Position
Substances whose molecules have more than one
element in them are called:
Compounds
When water is the solvent for a mixture, the mixture is
called an:
aqueous solution
Orange juice has a pH of 2.8 and would be considered
what type of inorganic compound according to the pH
scale?
An Acid because its ph is less than 7
Milk of Magnesia has a pH of 10.5 and would be
considered what type of inorganic compound according to
the pH scale?
A base or an alkaline
Which lipid molecule forms the foundation for the cell
membrane?
Phospholipids
Substances that are considered “pure” and are composed
of only one type of atom are called?
Element
Muscle tissue that when viewed under a microscope is
characterized by having multiple nuclei per cell and many
cross striations giving it a banded appearance is called?
Skeletal Muscle Tissue
( Skeletal muscle fibers are long, cylindrical cells with multiple nuclei located near the cell membrane, and their organized internal structure creates visible striations or bands when viewed under a microscope)
The most unusual type of connective tissue because its
matrix blood plasma is liquid is called:
Blood
What two body systems help maintain the proper pH of
body fluids?
Respiratory and urinary System
The important part of the cell contains most of the cell’s
genetic material and controls the complex process of cell
reproduction is called?
The Nucleus
A single projection extending from the cell surface;
structurally similar to cilia but much longer, that move and
propel the cell are called?
Flagellum
(Flagella are essentially long, whip-like structures that are used for cell locomotion, and while similar to cilia in structure, they are significantly longer and typically only one or a few are present on a cell.)
The active transport mechanism used to incorporate fluids
or dissolved substances into cells by trapping them in a
pocket of plasma membrane that pinches off int the cell to
form a vesicle; and contains a Greek word part that means
“drink” is called:
Pinocytosis
