Neurons (Text & Quiz)

How do neurons communicate to process sensory information?

• Through chemical signals only

• Through electrical signals only

• Through electrochemical signals

• Through mechanical signals

What is the primary function of neurons in the brain?

• To provide structural support to the brain

• To transmit electrical signals and process information

• To store nutrients for brain cells

• To protect the brain from infections

What are the three main components of a neuron?

• Dendrites, nucleus, axon

• Dendrites, soma, axon

• Soma, nucleus, myelin sheath

• Axon, synapse, terminal button

What is the main source of input for a neuron?

• Axon

• Soma

• Dendrites

• Myelin sheath

What is the function of the nucleus in a neuron?

• To extend signals to other neurons

• To direct protein synthesis and supply energy

• To insulate the axon

• To form synapses with other neurons

What is the role of the myelin sheath in a neuron?

• To receive information from other neurons

• To direct protein synthesis

• To insulate the axon and allow rapid signal transmission

• To form synapses with other neurons

What is a synapse?

• The main source of input for a neuron

• The place where the axon of one neuron comes in close contact with the dendrite of another neuron

• The process that extends far away from the soma

• The insulating substance covering the axon

What is the terminal button?

• The main source of output for a neuron

• The end of the axon that forms synapses with spines on the dendrites of neurons

• The insulating substance covering the axon

• The process that extends outward from the soma

What do synaptic vesicles package together?

• Receptor sites

• Neurotransmitters

• Ion channels

• Dendritic spines

Which type of neuron helps us receive information about the world around us?

• Motor neurons

• Sensory neurons

• Interneurons

• Multipolar neurons
