Aphy 101 Final Exam Latest All 100 Questions And
Correct Answers
Name the five primary taste sensations - ANSWER-Umami, Sweet, Sour,
Salty, Bitter
Why don't taste receptors diminish with age? - ANSWER-taste cells are
modified epithelial cells and divide continually
What are the parts of the outer ears? - ANSWER-auricle and the external
auditory meatus
What are the parts of the middle ears? - ANSWER-The middle ear begins
with the tympanic membrane, which is an air-filled space housing the
auditory ossicles. Three auditory ossicles are the malleus, incus, and
stapes.
3 Parts of the Labyrinths - INNER EAR - ANSWER-cochlea, semicircular
canals, and vestibule
,How are sound vibrations transmitted to the inner ear? - ANSWER-The
tympanic membrane vibrates the malleus, which vibrates the incus, then
the stapes.
The stapes vibrates the fluid inside the oval window of the inner ear.
What is static equilibrium? - ANSWER-help to maintain the position of the
head when
the head and body are still
the organs of static equilibrium are located within the bony vestibule of
the inner ear, inside the utricle and saccule (expansions of the
membranous labyrinth). A macula, consisting of hair cells and supporting
cells, lies inside the utricle and saccule
What is dynamic equilibrium? - ANSWER-help to maintain balance when
the head and
body suddenly move and rotate
The organs of dynamic equilibrium are called cristae ampullaris, and are
located in the ampulla of each semicircular canal of the inner ear
,retina - ANSWER-contains photoreceptors
cornea - ANSWER-helps focus entering light rays
iris - ANSWER-colored portion of the eye and adjusts the amount of light

what part of the eye are rods and cones found? - ANSWER-the inner
nervous tunic
, What are the rods and cones? - ANSWER-Rods are more sensitive to light
and function in dim light; they produce colorless vision. Cones provide
sharp images in bright light and enable us to see in color.
Define homeostasis - ANSWER-Body's maintenance of a stable
environment
What is a homeostatic mechanism? - ANSWER-the body maintains
homeostasis through a number of self-regulating control systems;
examples are regulating body temperature and pressure sensitive
receptors to regulate body pressure
Define matter - ANSWER-Anything that takes up space and has mass
(weight). It is composed of elements.
Define element - ANSWER-fundamental substance composed of chemically
identical atoms
Define atoms - ANSWER-smallest particle of an element; basic unit of
matter
