Axon, Dendrites, Neuroglial Cells

1 / 10

What are the small branches at the end of an axon called?

Nissl bodies

Axon hillocks

Terminal arborizations (telodendria)

Dendritic spines

2 / 10

What is a key characteristic of dendritic spines?

They are static structures

They are myelinated

They serve as sites for synapses

They contain large Golgi apparatus

3 / 10

What is the axon hillock?

A structure present in dendrites

A pyramid-shaped region of the perikaryon where the axon originates

The site of synaptic transmission

A region of the axon covered with myelin

4 / 10

What is the function of terminal boutons?

They store neurotransmitters and release them at synapses

They help generate action potentials

They provide structural support to neurons

They form myelin sheaths

5 / 10

Which of the following structures is absent in dendrites?

Microtubules

Nissl granules

Mitochondria

Golgi apparatus

6 / 10

What is the primary function of ependymal cells?

Providing myelination

Engulfing pathogens

Conducting nerve impulses

Producing cerebrospinal fluid

7 / 10

What is the primary function of dendrites?

Generate cerebrospinal fluid

Conduct action potentials away from the neuron

Form myelin sheaths

Increase the receptor surface area of a neuron

8 / 10

Which of the following is NOT a function of astrocytes?

Forming the blood-brain barrier

Supporting neuronal function

Regulating ion concentration

Producing cerebrospinal fluid

9 / 10

What is a key feature of the axon hillock?

It contains abundant Nissl bodies

It lacks large cytoplasmic organelles like Golgi bodies

It is the site of neurotransmitter release

It is only found in unipolar neurons

10 / 10

Which of the following best describes the axon?

Contains multiple Golgi bodies

Typically longer than dendrites and may be myelinated

Short, branched, and unmyelinated

Originates from dendritic spines
