The Nervous System Lessons 2b &3

What is the function of the midbrain?

• It controls vital processes such as respiration and heartbeat.

• It connects the pons and cerebellum and acts as a relay center for impulses.

• It carries messages to and from the spinal cord.

• It covers the brain and spinal cord.

Which part of the brainstem connects the medulla oblongata and cerebellum to the upper portions of the brain?

• Midbrain

• Pons

• Spinal cord

• Ventricles

What is the primary function of the medulla oblongata?

• It is a cavity in the brain.

• It controls vital processes such as respiration and heartbeat.

• It is responsible for special senses such as sight and hearing.

• It allows the body to respond to emergencies and stress.

What is the spinal cord primarily composed of?

• Membranes that cover the brain and spinal cord.

• A column of nervous tissue extending from the medulla oblongata to the second lumbar vertebra.

• Watery, clear fluid that surrounds the brain and spinal cord.

• A division of the autonomic nervous system.

What are the meninges?

• Membranes that cover the brain and spinal cord.

• A division of the autonomic nervous system.

• A cavity in the brain.

• Mixed nerves, both sensory and motor.

What is cerebrospinal fluid?

• A division of the autonomic nervous system.

• Watery, clear fluid that surrounds the brain and spinal cord.

• A column of nervous tissue.

• A relay center for impulses.

Which of the following is true about cranial nerves?

• They are only responsible for involuntary muscle control.

• They carry messages to and from the spinal cord.

• Some are responsible for special senses such as sight, hearing, taste, and smell.

• They are a division of the autonomic nervous system.

What is the role of spinal nerves?

• They are responsible for special senses.

• They carry messages to and from the spinal cord and are mixed nerves, both sensory and motor.

• They control vital processes such as respiration and heartbeat.

• They are a cavity in the brain.

What is the function of the sympathetic division of the autonomic nervous system?

• It covers the brain and spinal cord.

• It allows the body to respond to emergencies and stress.

• It is a cavity in the brain.

• It connects the pons and cerebellum.

Which division of the autonomic nervous system is responsible for calming the body and conserving energy?

• Sympathetic

• Parasympathetic

• Cranial nerves

• Spinal nerves
