Nervous System

Dendrites conduct impusles:

• toward cell bodies

• away from cell bodies

• within cell bodies

• none of the above

The autonomic nervous system consists of the:

• peripheral and afferent nervous system

• sympathetic and parasympathetic nervous system

• sympathetic and efferent nervous system

• parasympathetic and somatic nervous system

Small, oval neuroglial cells with spider-like process which carry out phagocytosis are called:

• microglia

• astrocytes

• satellite cells

• ependymal cells

Which of the following would the somatic division of the peripheral nervous system innervate?

• skeletal muscle in your arm

• smooth muscle in the wall of your stomach

• cardiac muscle in your heart

• smooth muscle in the wall of your bladder

The olfactory nerve carries impulses associated with:

• taste

• equilibrium

• smell

• pain

Elevated ridges or folds of tissue that make up the cerebral cortex of the brain are called:

• sulci

• fissures

• gyri

• nuclei

In a reflex arc, the afferent neurons conduct impulses:

• towards the central nervous system

• away from the central nervous system

• in between two neurons

Schwann cells have a similar function in the peripheral nervous system as these cells have in the central nervous system:

• oligodendrocytes

• astrocytes

• microglia

• ependymal cells

The part of the nervous system that transmits impulses from the CNS to the skeletal muscle is the:

• somatic nervous system

• autonomic nervous system

• central nervous system

• afferent division

The nervous system is organized to do which of the following?

• detect changes in the external environment

• detect changes in the internal environment

• evaluate changes in the environment

• all of the above
