What are the two major subdivisions of the nervous system?

• Autonomic and Somatic Nervous Systems

• Peripheral Nervous System (PNS) and Central Nervous System (CNS)

• Sensory and Motor Systems

• Sympathetic and Parasympathetic Systems

How do sensory receptors collect information?

• By sending signals to the brain

• By detecting changes inside and outside the body

• By producing electrical impulses

• By creating sensations

How does the central nervous system integrate incoming information?

• By storing it in the spinal cord

• By creating sensations, adding to memory, or helping produce thoughts

• By transmitting it to muscles

• By converting it into electrical signals

What are the two types of motor functions of the nervous system?

• Sensory and Motor Functions

• Autonomic and the Somatic Nervous Systems

• Voluntary and Involuntary Functions

• Reflexive and Non-reflexive Functions

List the functions of cells that form support neurons.

• They transmit signals and store information

• They provide structural framework and carry out phagocytosis

• They produce hormones and enzymes

• They regulate blood flow and oxygen levels

What is the function of microglia in the central nervous system?

• They insulate axons with myelin

• They remove bacterial cells and cell debris

• They transmit electrical signals

• They produce neurotransmitters

What is the function of oligodendrocytes in the central nervous system?

• They provide structural support

• They produce insulating layers of myelin sheaths

• They regulate nutrients and ions

• They form inner lining in the brain

What is the function of astrocytes in the central nervous system?

• They remove cell debris

• They provide structural support and help regulate nutrients and ions

• They produce myelin sheaths

• They transmit nerve impulses

What is the function of ependymal cells in the central nervous system?

• They insulate axons

• They form inner lining that encloses spaces in the brain

• They transmit sensory information

• They produce neurotransmitters
