Nervous System Quiz ANS 1

Which part of the nervous system involves initiation and transmission of nerve signals to control skeletal muscles?

• Somatic motor portion

• Visceral sensory components

• Autonomic motor components

• Parasympathetic division

What is the function of the autonomic nervous system (ANS)?

• To maintain homeostasis

• To control skeletal muscles

• To detect stimuli from special senses

• To prepare the body for emergencies

What is the parasympathetic division also known as?

• Rest-and-digest division

• Fight-or-flight division

• Thoracolumbar division

• Cranio-sacral division

Where do sympathetic preganglionic neurons originate?

• Lateral horns of the T1–L2 spinal cord segments

• Brainstem or lateral gray matter of the S2–S4 spinal cord segments

• Cerebrum

• Spinal cord and brain stem

What is the sympathetic division concerned with?

• Preparing the body for emergencies

• Maintaining homeostasis at rest

• Detecting stimuli from blood vessels

• Controlling skeletal muscle activity

What is the parasympathetic division also called?

• Cranio-sacral division

• Thoracolumbar division

• Fight-or-flight division

• Somatic motor portion

Which division is also known as the thoracolumbar division?

• Sympathetic division

• Parasympathetic division

• Somatic sensory portion

• Autonomic motor components

How do parasympathetic preganglionic axons differ in branching compared to sympathetic preganglionic axons?

• They have more branches

• They have fewer branches

• They have the same number of branches

• They have no branches

Where are parasympathetic autonomic ganglia typically located?
