BSC 197 Exam 4 Questions With Correct
Answers
What is homeostasis? - CORRECT ANSWER✔✔-Maintaining steady state
| | | | | | |
of health
| |
Advantages and trade offs of being multicellular - CORRECT
| | | | | | | | |
ANSWER✔✔-Size, easy to stay in one spot for aquatic organisms, and | | | | | | | | | | |
cells can become specialized to do one function very well
| | | | | | | | |
The 3 main types of neurons and their roles - CORRECT ANSWER✔✔-
| | | | | | | | | | |
Sensory-receive info and pass it along. Interneurons-act as intermediate
| | | | | | | | |
by conducting a signal from sensory neurons. Motor neurons-affect
| | | | | | | | |
physiological change or movement in response to signal from sensory
| | | | | | | | | |
neurons.
Basic structure of a neuron and the function of each part of Cell -
| | | | | | | | | | | | | |
CORRECT ANSWER✔✔-Dendrite receives signal. Axon transmits signal.
| | | | | | |
Narrow gap between an axon of one neuron and a dendrite of another
| | | | | | | | | | | | |
is called a synaptic cleft. Entire structure of these is a synapse. Signal
| | | | | | | | | | | | |
molecules are released by axon terminal. | | | | |
, How depolarization and firing of action potential occur in neurons -
| | | | | | | | | | |
CORRECT ANSWER✔✔-Depolarization is the rapid increase in
| | | | | | |
membrane potential that occurs along the membrane of the axon in
| | | | | | | | | | |
response to the summed dendritic signal at the axon hillock
| | | | | | | | |
Glial cells and myelin sheaths - CORRECT ANSWER✔✔-Myelin sheaths
| | | | | | | | |
act like plastic insulation around electrical wire.
| | | | | |
The central and peripheral nervous systems - CORRECT ANSWER✔✔-2
| | | | | | | | |
branches of nervous system | | |
How simple reflexes occur - CORRECT ANSWER✔✔-Direct activation of a
| | | | | | | | |
motor neuron by a signal from a sensory neuron
| | | | | | | | |
structure and function of sensory cells - CORRECT ANSWER✔✔-Touch-
| | | | | | | |
How membrane channels are involved in senses - CORRECT
| | | | | | | | |
ANSWER✔✔-
The flavors detected by human taste buds - CORRECT ANSWER✔✔-
| | | | | | | | |
Sweet, bitter, salty, sour, umami
| | | |
The role of Opsins in human vision - CORRECT ANSWER✔✔-React to
| | | | | | | | | | |
photons of light and change their shape
| | | | | |
