Bio 181 ASU Module 13-14 Exam WITH
COMPLETE SOLUTION| Graded A+
Draw an action potential in the axon of a neuron and indicate which ions flow into the neuron
and out of the neuron as the action potential passes at the point where the electrodes are in the
cell. Be sure to assign on the Y-axis the mV of each of these areas. This should be as
described in my lectures. -
True/False
The cell body refers to the part of the neurons that begin at the dendrites and extend to the
axon terminal. - false
True/False
The autonomic nervous system contains the sympathetic and the parasympathetic nervous
system. - true
True/False
Only pre-synaptic neurons are coated with myelin. - false
True/False
Potassium ions are at high concentrations inside of cells including in neurons. - true
, The neural tissues are:
a. Spinal cord, sensory neurons, and cell body
b. Spinal cord, sensory neurons, and brain
c. Brain, and sensory neurons
d. Pituitary and hypothalamus
e. None of the above - b. Spinal cord, sensory neurons, and brain
True/False
When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. -
true
Draw a neuron, and label all the parts as described in lecture. -
True/False
Fast neurons as described in lecture require cytoplasmic signal transduction to open an
ion channel. - false
The action potential is:
a. A result of hyper-polarization.
b. A result of the movement of calcium ions.
c. A result of the action of the cell body.
d. A result of microtubules.
e. A result of the movement of ions. - e. A result of the movement of ions.
