Test-The Nervous System

Which function is associated with the nervous system?

• Red blood cells creating new blood cells

• Joints helping connect the bones

• Receiving information from the brain

• Food digesting through the stomach

1. A student waits for the bell to ring, so he can go home for the weekend. The list shows different ways the student’s brain processes information during the event, in no particular order.

   1. 1. Sensory neurons gather information in the ears.

   2. 2. Motor neurons send a response to the legs to get up and walk out the door.

   3. 3. Interneurons pass information to the spinal cord and the brain.

Which of the following lists the correct order of how the student’s brain receives information from the first event of the alarm bell ringing to the last event of the student walking out the door?

• A. 2, 1, 3

• B. 1, 3, 2

• C. 3, 1, 2

• D. 1, 2, 3

Is breathing a voluntary or involuntary action?

• Voluntary, because you have to think about when to take a breath.

• Voluntary, because you have to open your mouth to breathe.

• Involuntary, because the brain stem sends signals to your brain to breathe.

• Involuntary, because the lungs tell the brain when to inflate and deflate.

What are some of the roles of the central nervous system? Select all correct answers.

• Receives information from outside the body through the senses

• Controls heart rate

• Helps fight infection from pathogens

• Reacts to the environment by activating an appropriate response

Anna’s nervous system worked to sense, process, and respond to stimuli. It includes the main functions of the nervous system that Anna uses to capture the butterfly as well as identifying the stimulus and the response. Be sure to include vocabulary words such as sensory neuron, interneuron, and motor neuron.

Identify the functions of the nervous system related to the action of checking knee reflexes and the structures that are and are not involved. Be sure to include vocabulary words such as sensory neuron, interneuron, and motor neuron.

What is the primary role of sensory neurons in the nervous system?

• To transmit signals from the brain to muscles

• To gather information from the environment

• To create new neurons

• To process information within the brain

Which part of the nervous system is responsible for processing and interpreting sensory information?

• The spinal cord

• The brain

• The motor neurons

• The sensory neurons

How do motor neurons function in the nervous system?

• They interpret sensory data

• They create new neural pathways

• They transmit signals to muscles and glands

• They gather sensory information

What role do interneurons play in the nervous system?

• They transmit signals from the brain to muscles

• They connect sensory and motor neurons

• They create new neural pathways

• They gather information from the environment
