HBS FINAL REVIEW

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

• Axon

• Dendrite

• Myelin Sheath

• Node of Ranvier

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

• To receive signals from other neurons

• To transmit electrical impulses away from the cell body

• To insulate the axon and speed up signal transmission

• To connect neurons to muscles

Which structure in a neuron contains the nucleus?

• Axon

• Dendrite

• Cell body

• Node of Ranvier

What is the function of the Node of Ranvier in a neuron?

• To store neurotransmitters

• To allow for faster transmission of nerve impulses by enabling saltatory conduction

• To protect the neuron from damage

• To produce energy for the neuron

Which part of the neuron transmits electrical impulses away from the cell body?

• Dendrite

• Axon

• Myelin Sheath

• Nucleus

Which number in the diagram most likely represents the axon?

• 1

• 2

• 3

• 4

In what direction does the signal travel in a neuron?

• From axon terminal to dendrite

• From dendrite to axon terminal

• From cell body to dendrite

• From synapse to nucleus

What is the function of a sensory neuron?

• To carry impulses from sensory organs to the central nervous system

• To carry impulses from the brain to muscles

• To connect sensory and motor neurons

• To produce hormones

What is the function of a motor neuron?

• To carry impulses from the central nervous system to muscles or glands

• To carry impulses from sensory organs to the brain

• To connect two sensory neurons

• To transmit signals within the spinal cord only

What is the function of an interneuron?

• To connect sensory and motor neurons within the central nervous system

• To carry impulses from muscles to the brain

• To transmit signals to glands only

• To sense changes in the environment
