Nervous System Quiz based on slides

What is the purpose of the nervous system?

• To provide structural support to the body

• To control and communicate information throughout the body

• To transport nutrients and oxygen to cells

• To protect the body from infections

What is the nervous system made of? List all its components.

• Bones, muscles, and cartilage

• Neurons, the brain, and the spinal cord

• Blood, blood vessels, and the heart

• Lungs, bronchi, and alveoli

How many neurons does a human brain contain on average?

• About 10 million

• About 100 billion

• About 1 trillion

• About 86 billion

What is the "highway" in our body or the "middle man" that makes possible the messages travel from brain to rest of the body or vice versa?

• The heart

• The lungs

• The spinal cord

• The digestive tract

What is the cerebrum?

• The lower part of the brain responsible for balance and coordination

• The part of the brain that connects to the spinal cord

• The largest part of the brain associated with higher brain functions

• The part of the brain that controls involuntary actions

What is the cerebellum?

• The part of the brain that controls involuntary actions

• The largest part of the brain associated with higher brain functions

• The lower part of the brain responsible for balance and coordination

• The part of the brain that connects to the spinal cord

What is the brain stem?

• The part of the brain that controls involuntary actions

What is a somatic system? What is it made of and what is its purpose?

• A system that controls voluntary muscle movements and is made of sensory and motor neurons

• A system that controls involuntary actions and is made of the brain and spinal cord

• A system that provides structural support and is made of bones and muscles

• A system that transports nutrients and is made of blood vessels and the heart

What are autonomic functions?

• Functions that require conscious thought and control

• Functions that are controlled by the somatic nervous system

• Functions that are involuntary and regulated by the autonomic nervous system

• Functions that are related to the skeletal system

What is the peripheral nervous system?

• The system that includes the brain and spinal cord

• The system that controls voluntary muscle movements

• The system that includes nerves outside the brain and spinal cord

• The system that controls the heart and lungs
