BSC2085 Test 1 Chap 1-7 UPDATED ACTUAL Questions and
CORRECT Answers
What is human anatomy? The scientific study of the body's structures.
What does the term 'anatomy' derive from? A Greek root meaning 'to cut apart'.
What is human physiology? The scientific study of the chemistry and physics of the body's structures and their
functions.
What is a cell? The basic unit that performs all functions of life.
What is a tissue? A group of many similar cells that work together to perform a specific function.
What is an organ? An anatomically distinct structure composed of two or more tissue types that
performs specific physiological functions.
What is an organ system? A group of organs that work together to perform major functions or meet
physiological needs.
What are the definitive functions of human life? Organization, metabolism, movement, reproduction, responsiveness, and
homeostasis.
What is homeostasis? The maintenance of stable internal conditions in the body despite fluctuations.
What is a set point in physiology? The physiological value around which the normal range fluctuates.
What is the normal range? The set of values that is optimally healthful and stable.
What is the set point for normal human body Approximately 37°C (98.6°F).
temperature?
What role do control centers play in homeostasis? They monitor and react to deviations from homeostasis using feedback
mechanisms.
, What is negative feedback? A mechanism that reverses a deviation from the set point to maintain body
parameters within their normal range.
What is positive feedback? A mechanism that intensifies a change in the body's physiological condition rather
than reversing it.
When is positive feedback normal in the body? Only when there is a definite end point.
What is the anatomical position? The body standing upright, feet at shoulder width and parallel, toes forward,
upper limbs out to the sides, and palms facing forward.
Why is the anatomical position important? It reduces confusion by providing a standard orientation for the body.
What is the anatomical position used for in describing It serves as a standard reference point regardless of the body's actual orientation.
body structures?
What is the sagittal plane? An imaginary plane that divides the body vertically into right and left sides.
What defines the midsagittal or median plane? It runs directly down the middle of the body, dividing it into equal right and left
sides.
What is the difference between the midsagittal and The midsagittal plane divides the body into equal halves, while the parasagittal
parasagittal planes? plane divides it into unequal right and left sides.
What does the frontal (coronal) plane do? It divides the body into anterior (front) and posterior (rear) portions.
What is the function of the transverse plane? It divides the body horizontally into upper and lower portions.
What does the term 'anterior' refer to in anatomical It describes the front or direction toward the front of the body.
terminology?
What does 'posterior' mean in anatomical terms? It refers to the back or direction toward the back of the body.
What does 'superior' indicate in anatomical positioning? It describes a position above or higher than another part of the body.
What does 'inferior' mean in anatomical terminology? It describes a position below or lower than another part of the body.
