Chapter 3 Day 2 Review

What is the primary function of glial cells in the nervous system?

• Transmit electrochemical signals

• Act as the 'support' cells

• Produce neurotransmitters

• Store memories

Which part of the neuron is responsible for receiving signals from other neurons?

• Axon terminal

• Soma

• Dendrite

• Myelin sheath

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

• To transmit signals to other neurons

• To insulate the axon and speed up signal transmission

• To receive signals from other neurons

• To store genetic information

What is the function of the soma in a neuron?

• Transmits electrical signals to other neurons

• Coordinates information-processing tasks and keeps the cell alive

• Protects the neuron from external damage

• Stores neurotransmitters for release

What is the primary function of the axon in a neuron?

• To release neurotransmitters

• To carry messages from soma to terminals

• To insulate the neuron

• To store nutrients

Where are neurotransmitters released in a neuron?

• Soma

• Dendrite

• Axon terminals

• Nodes of Ranvier

What is the function of the synapse?

• To store memories

• To transmit electrical signals within a neuron

• To allow communication between neurons

• To produce neurotransmitters

What is the primary function of sensory neurons?

• Carry signals from the brain to muscles

• Connect sensory and motor neurons

• Receive information from the external world and communicate it to the brain

• Produce movement in muscles

Where does the electrical signal travel inside the neuron?

• From the axon terminals to the dendrites.

• From the synapse to the axon.

• From the dendrites, through the axon, to the axon terminals.

• From the cell body to the synapse.

What is the resting potential of a neuron?

• +70 mV

• -70 mV

• 0 mV

• +30 mV
