Nervous System PD

What is the primary function of the nervous system?

• Transporting nutrients throughout the body

• Carrying signals from the brain to the rest of the body

• Filtering waste products from the blood

• Producing hormones for growth

What type of tissue makes up the nervous system?

• Epithelial tissue

• Connective tissue

• Muscle tissue

• Nervous tissue

What is the primary cell type found in the nervous system?

• Schwann cell

• Glial cell

• Neuron

• Muscle cell

Which characteristic describes neurons regarding cell division?

• They divide rapidly throughout life

• They are amitotic, meaning they do not divide

• They divide only during embryonic development

• They divide only when damaged

What are the supporting cells in the nervous system that protect neurons called?

• Myelin cells

• Glial cells

• Axon cells

• Dendrite cells

What structures are typically found within the cell body of a neuron?

• Axon terminals and myelin sheath

• Nucleus, nucleolus, and organelles

• Dendrites and axon hillock

• Schwann cells and nodes of Ranvier

What is the primary function of dendrites in a neuron?

• Transmitting electrical impulses away from the cell body

• Generating neurotransmitters

• Receiving signals from other neurons

• Protecting the axon

Where does the axon typically originate from in a neuron?

• Dendrite

• Cell body

• Axon hillock

• Axon terminal

What is a very long axon sometimes referred to as?

• A dendrite extension

• A glial process

• A nerve fiber

• A neuromuscular junction

What happens in the secretory region of a neuron?

• Electrical signals are generated

• Stimuli are received

• Neurotransmitters are released

• The cell body is protected
