Fill in the Blanks: The ____________ are the receiving end of a neuron, while the ____________
conducts nerve impulses away from the cell body.
Dendrites; axon
Match the following neurotransmitters with the correct description.
Dopamine: Regulates emotional responses and muscles tone.
Norepinephrine: Produced by the adrenal glands.
Acetylcholine: Found at the neuromuscular junctions.
True or False: If false, explain why the statement is false. The peripheral nervous system consists of the
brain and spinal cord.
This statement is false. The central nervous system consists of the brain and spinal cord. The peripheral
nervous system includes all nerves that are not located in the brain or spinal cord.

Match the following lobes of the brain with the correct function.
Temporal: Contains sensory areas for hearing and smelling.
Frontal: Controls higher level executive functions.
Parietal: Receives sensory information from body receptors.
Occipital: Interprets visual input.
Which of the following structures of the spinal cord contains the cell bodies of afferent neurons?
Dorsal root ganglion
Describe the function of the sympathetic nervous system when a threat is present.
The sympathetic nervous system (SNS) is often referred to as the "fight or flight" system. When in
immediate danger, muscles require a steady, increased supply of glucose and oxygen for muscular
contraction. The SNS accelerates the heartbeat, dilates the bronchi, and increases the respiratory rate.
This supplies the increased need for oxygen throughout the body. The SNS also causes the liver to
deliver more glucose for the body's increased metabolic needs. Sympathetic activation inhibits the
digestive tract because digestion is not an immediate necessity when in danger or under attack.
True or False: if false, explain why the statement is false. Visual information from the left side will
eventually be interpreted by the left side of the brain.
This statement is false. Sensory information gathered from the left side of the body will eventually be
interpreted in the right side of the brain.
Explain the main steps in the process of hearing..
First, sound waves are funneled into the external auditory canal, causing the eardrum to vibrate. The
vibrations transmit to the ossicles, which push against the fluid inside the cochlear duct. As the fluid
