CNS- Practice pt. 1 from lecture

What is the function of the nervous system?

• It provides structural support to the body.

• It detects impulses from the senses and acts as the control center.

• It circulates blood throughout the body.

• It aids in the digestion of food.

Which of the following is NOT a major organ of the nervous system?

• Brain

• Spinal cord

• Heart

• Nerves

Into which two main parts is the nervous system divided?

• Central nervous system and Peripheral nervous system

• Autonomic nervous system and Somatic nervous system

• Sympathetic nervous system and Parasympathetic nervous system

• Enteric nervous system and Central nervous system

What does the Central nervous system (CNS) consist of?

• Brain and spinal cord

• Cranial nerves and spinal nerves

• Peripheral nerves and autonomic ganglia

• Somatic nerves and sensory organs

Where do cranial nerves originate?

• In the spinal cord

• In the peripheral nervous system

• In the brain

• Outside the central nervous system

Where do spinal nerves originate?

• In the brain

• In the peripheral nervous system

• In the spinal cord

• Outside the central nervous system

What is the function of the Sensory (Afferent) Division of the Peripheral Nervous System?

• It sends impulses from the CNS to the muscles and glands.

• It controls involuntary muscle movements.

• It sends impulses from the senses to the CNS.

• It controls voluntary muscle movements.

Which division of the Peripheral Nervous System is responsible for the "fight or flight" response?

• Sensory (Afferent) Division

• Motor (Efferent) Division

• Sympathetic Division

• Parasympathetic Division

What is the role of the Parasympathetic Division of the Peripheral Nervous System?

• It sends impulses from the CNS to the muscles and glands.

• It prepares the body for emergency situations.

• It reduces sympathetic response and provides resting functions such as digestion and urination.

• It controls voluntary muscle movements.

What does the Autonomic Nervous System control?

• Involuntary muscle control

• Voluntary muscle control

• Sending impulses from the senses to the CNS

• Sending impulses from the CNS to the muscles and glands
