Quiz on the Nervous System

What is the functional unit of the nervous system?

• Axon

• Neuron

• Dendrite

• Synapse

What is the main function of the functional unit of the nervous system?

• To provide structural support

• To transmit electrical signals

• To supply nutrients to nerve cells

• To protect nerve cells from damage

What should be discussed when talking about the organization of the nervous system?

• The chemical composition of neural tissue

• The genetic makeup of neurons

• The overall structure and arrangement of the nervous system

• The types of diseases that can affect the nervous system

What are the two types of neurons that need to be differentiated when discussing their structure and classification?

• Sensory and Motor

• Afferent and Efferent

• Sympathetic and Parasympathetic

• Upper and Lower neurons

Which part of a neuron is known as the input zone?

• Axon

• Cell body (soma)

• Axon hillock

• Dendritic (input) zone

What is the function of the axon hillock?

• It is the input zone of the neuron.

• It is responsible for the output of synaptic knobs.

• It serves as the summation zone of the neuron.

• It increases the speed of impulse propagation.

What is the primary role of the synaptic knobs in a neuron?

• They serve as the input zone.

• They are responsible for the summation of signals.

• They are the part where the cell body connects to the dendrites.

• They function as the output zone of the neuron.

What is one of the factors that can affect the speed of impulse propagation in peripheral nerves?

• The color of the neuron

• The presence or absence of myelination

• The length of the synaptic knobs

• The size of the cell body

What do type A, B, and C fibers differ in?

• Color and texture

• Function, size, and relative speed of impulse transmission

• Location in the body

• Ability to regenerate

What is one of the topics that should be discussed in relation to nerve transmission?

• The impact of temperature on nerve transmission

• The role of ions in nerve transmission during different stages

• The influence of exercise on nerve transmission

• The effect of age on nerve transmission
