Nervous System & Senses Review

What type of receptors respond to factors such as pressure, stretch, and vibration that change the position of a receptor?

• Nociceptors
• Mechanoreceptors
• Thermoreceptors
• Chemoreceptors

What is the function of the peripheral nervous system?

• Control voluntary movements
• Control involuntary movements
• Control the brain and spinal cord
• Control everything outside of the brain and spinal cord.

What are the two types of nervous tissue found in a cross section of both the spinal cord and the brain?

• White matter and gray matter
• Schwann cells and oligodendrocytes
• Sensory neurons and motor neurons
• Astrocytes and ependymal cells

Which hemisphere of the cerebrum is more analytical?

• Left hemisphere
• Right hemisphere
• Both hemispheres are equally analytical
• None of the above, the cerebrum is not responsible for analytical thinking

How do impulses travel along myelinated fibers?

• The impulse "leaps" from node to node
• The impulse flows directly through the myelin sheath
• The impulse travels through the dendrites
• The impulse travels through the astrocytes

The most numerous of all glial cells are:

• microglia
• astrocytes
• Schwann cells
• ependymal cells

Which statement about gray matter is true?

• It is charged with thought, learning, and reasoning.
• It forms the interios of the brain.
• It consists of myelinated fibers.
• It secretes cerebrospinal fluid.

The cardiac and respiratory centers are found in the:

• pons
• cerebellum
• diencephalon
• medulla oblongata

The limbic system is charged with:

• emotion and learning
• identifying the location of pain
• planning muscle movements to form words
• determining muscle movements to perform a task

Nociceptors respond to:

• various chemicals inside and outside the body
• pressure, stretch, or vibration
• pain from tissue damage
• changes in temperature
