Nervous System Check Understanding

Stimulation of the sympathetic nervous system most frequently results in which of the following?

• Acceleration of heart and breathing rates and dilation of pupils

• Stimulation of tearing, salivation, and peristalsis

• Calming of the body

• Construction of the muscles of the hands and feet

• Raising the perceptual threshold of olfactory and gustatory receptors

Activation of the parasympathetic nervous system results in which of the following?

• An increase in pupil dilation

• An increase in respiratory rate

• A decrease in digestion

• A decrease in salivation

• A decrease in heart rate

Which of the following correctly pairs subdivisions within the major divisions of the human nervous system?

• Somatic.. Endocrine and endocrine

• Central.. Somatic and sympathetic

• Autonomic.. Sympathetic and parasympathetic

• Sympathetic.. Parasympathetic and autonomic

• Peripheral.. Central nervous system and the spinal cord

The function of dendrites is to:

• Receive information from other neurons

• Secrete neurotransmitters to the postsynaptic neuron

• Provide energy for the synthesis of acetylcholine

• Connect the cell body with the terminal branches

• Speed up transmission of synaptic neurotransmitters

Ben was enjoying a walk in the woods on a beautiful Saturday afternoon. As he went around a curve, he noticed a bear walking towards him. Immediately his pupils dilated, he began to perspire, and his heart accelerated. These changes are most closely related to the function of the:

• Angular gyrus

• Hippocampus

• Parasympathetic nervous system

• Sympathetic nervous system

• Ventricular system
