Questions and Correct Answers, 100%
Correct, Latest 2024/2025.
The autonomic nervous system contains the sympathetic and trie parasympathetic
nervous system.
True
The post-synaptic cell can be:
In glands, muscle cells, neurons
The axon hillock in the pre-synaptic neuron fires based on temporal and spatial summation of inputs.
True
Only pre-synaptic neurons are coated with myelin.
False
The axon from a pre-synaptic cell contacts the axon of another neuron.
False
Acetylcholine esterase breaks acetylcholine into muscarinic acid
False
Excitatory synapses cause depolarization of the post-synaptic cell.
True
The action potential is:
A result of the movement of ions
Fast neurons as described in lecture are fast because they are surrounded by a type of glial cell that
results in a myelin coating
False
The central nervous svstem (CNS) contains:
none of the answers are correct
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
Spinal cord, sensory neurons, and brain
In the motor end plate, the event that is the immediate trigger for exocytosis is:
Calcium Ions
The membrane potential (resting potential) is largely set by the Na-K-ATPase pump.
true
The cell body refers to the part of the neurons that begin at the dendrites and extend to the axon
terminal.
false
Acetylcholine exocytosed from the presynaptic cell travels to the postsynaptic cell to start the action
potential in the postsynaptic cell.
true
Fast neurons as described in lecture require cytoplasmic signal transduction to open an ion channel.
False
Excitatory synapses cause hyperpolarization of post-synaptic cells.
false
Excitatory synapses make the post-synaptic cell less likely to fire.
false
The receptors in post-synaptic cells are the basis on which the synapse can be defined as inhibitory or
excitatory.
false
When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate.
true
Receptors are made from membrane bound polyribosomes.
true
terminal web
is a site of exocytosis
The resting potential of neurons Is:
