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:
