• Neurology

• Psychology

• Biology

• Anthropology

Which of the following is not function of the nervous system

• Controls activities of the body

• Regulates metabolic activity

• Responds to stimuli and relays

  impulses to the brain

• Interpretation of impulses

  occurs in the brain

Which peripheral nervous system subdivison only has afferent neurons?

• Somatic system

• Visceral system

Which peripheral nervous system subdivison supplies motor and sensory fibers to structures of the body wall or soma?

• Somatic system

• Visceral system

Match the following types of neurons:

• the most

  common making up the brain

  and spinal cord

• Multipolar neurons

• located in

  the eye

• Pseudounipolar neurons

• found in

  insects but not in vertebrate

  animals

• Unipolar neurons

• have

  bundled dendrites and are found

  in the spinal cord

• Bipolar neurons

Neurons are the support cells, glial cells are main functional cells. True or False?

• True

• False

Match the following

• Clean up squad of Central Nervous

  System

• Astroglia Cells

• Function to provide myelin sheaths

  within Central Nervous System

• Oligodendroglia Cells

• Provide myelin sheaths

  around axons in the PNS

• Microglia Cells
