AECL/BIOL 365: Exam 2 Review
1. Birds have a single gland used for the preening of feathers called the
Uropygial gland
2. Mammals have four types of glands:
Sweat, Scent, Sebaceous, Mammary
,
.
,
, and
3. The hypothalamus, master center of the
system, produces
that stimulate the
gland to release its hormones.
Endocrine, releasing, pituitary
.
hormones
4.
are controlled by follicle stimulating hormone and luteinizing hormone. These
also produce
which is important for the preparation of labor and for cervix
dilation.
Ovaries, relaxin
5. The bird stomach is divided into 2 portions: the
which produces the digestive
juices and the
that grinds the food by muscle action.
Proventriculus, gizzard
6. Some mammals have four stomach tissues:
and
.
Esophageal, cardiac, fundic, pyloric
,
,
,
7. The
or appendix is a pouch in the digestive tract wall that contains bacteria to aid in
digestion. In some vertebrates, this structure is
or has a reduced/absent function.
Cecum, vestigial
8. The
is the largest gland in vertebrates. It filters blood and it also produces bile.
Bile is stored in the
.
Liver, gall bladder
9. The
is the major water and salt balance organ in vertebrates. It is composed of
millions of functional units called
.
Kidney, nephron
10.
fish are fish that migrate between salt and fresh water. Salmon are
regards to this, while the Atlantic eel is
.
Diadromous, anadromous, catadromous
11. Neurons can be divided into 3 classes:
Motor, sensory, interneurons
,
, and
in
.
12.
synapses occur when an action potential arrives at the synapse. This opens the
calcium ion channels that causes the ions to enter the cell. This triggers the release of
into the synaptic cleft. This then binds to the
exciting it.
The postsynaptic
is propagated. The neurotransmitter is then
degraded. Then it is resynthesized, returned, and stored.
Chemical, neurotransmitter, postsynaptic membrane, action potential
13.
is a type of chemoreception where its receptor cells are found primarily on the
tongue. One type of receptor cell,
, is used to taste for toxicity.
Taste, bitter
14. In vertebrate, the organ of balance is the
Labyrinth, cochlea
, and the organ of hearing is the
.
15. In the eye, the
provides achromatic vision that is used for vision in dim light.
Whereas,
provide chromatic vision that is useful during abundant light.
Rods, cones
16.
vision produces a broad overlap of fields of vision that allows for more depth
perception. On the other hand,
vision provides a wide field of vision but with less
depth perception.
Binocular, monocular
17.
species produce many offspring that have low survival and have little parental
care.
species produce a few offspring that have high survival with a great deal of
parental care.
R-selected, k-selected
18. In
, there is one male and one female pair bond that lasts for at least the breeding.
is where there are multiple pair bonds that occur at one time or sequentially.
is where there are no pair bonds.
Monogamy, Polygamy, Promiscuity
