Bio 181 ASU Exam 3 Solved 100% Correct!!
T or F: Potassium ions are at high concentrations inside of cells, including
neurons
True
The action potential is a result of:
the movement of ions
The post-synaptic cell can be:
in glands, muscle cells and neurons
Th resting potential of a neuron is
-60mV
T or F: The cell body refers to the part of the neurons that begin at the dendrites
and extend to the axon terminal
false
T or F: Voltage gated ion channels open when a protein binds to the receptor
false
T or F: Excitatory synapses cause hyperpolarization of post-synaptic cells
false
T or F: Acetylcholinesterase breaks acetylcholine into muscarinic acid
false
In the motor end plate, the event that is the immediate trigger for exocytosis is
calcium ions
T or F: Fast Neurons as described in lecture require cytoplasmic signal
transduction to open an ion channel.
False
T or F: Only pre-synaptic neurons are coated with myelin.
False
T or F: When the presynaptic cell contacts a muscle cell, the synapse area is
called a motor end plate.
True
T or F: Receptors are made from membrane-bound polyribosomes.
True
The terminal web:
is a site of exocytosis
T or F: Excitatory synapses cause depolarization of the post-synaptic cell
True
T or F: The membrane potential (resting potential) is largely set by the Na-K-
ATPase pump.
true
The neural tissues are:
spinal cord, sensory neurons and brain
T or F: the axon from a pre-synaptic cell contacts the axon of another neuron
false
T or F: The receptors in post-synaptic cells are the basis on which the synapse
can be defined as inhibitory or excitatory
