7th Grade Science Nervous System Quiz

Instructions from the spinal cord to the muscles in the human leg are transmitted through structures known as:

• sensory neurons

• motor neurons

• interneurons

• connective neurons

Electrical messages are first detected by which part of a neuron

• dendrite

• nucleus

• terminal branch

• mitochondrion

The breathing rate of a human increases after exercise. The part of the brain that controls this involuntary action is

• cerebrum

• cerebellum

• medulla

• spinal cord

A man suffers a head injury during a basketball game. For several days afterward, he can't remember his social media passwords. This memory loss results from damage to the man's

• cerebrum

• cerebellum

• medulla

• spinal cord

The nervous system's process likely follows which of these pathways

• motor nerve - central nervous system - sensory nerve

• motor nerve - sensory nerve - central nervous system

• sensory nerve - central nervous system - motor nerve

• sensory nerve - motor nerve - central nervous system

Which part of the human brain is correctly paired with its function?

• spinal cord - coordinates learning activities

• cerebellum - serves as the center for breathing and other actions

• cerebrum - serves as the center for thinking and learning

• medulla - maintains muscle control

When a children runs inside after hearing a car crash outside, the child is using:

• the central nervous system, only

• the peripheral nervous system, only

• both the central and peripheral nervous systems

• neither the central nor the peripheral nervous system

Which structure in humans transmit electrical messages?

• veins

• lymphocytes

• neurons

• nephrons

The peripheral nervous system consists of the

• neurons located in the brain and the spinal cord

• nerves that extend from the brain and the spinal cord

• interneurons of the central nervous system

• portions of the brain known as the medulla and cerebellum

What is the role of the sensory nerves in the body?

• the transmission of messages straight to motor neurons

• the detection of information outside of the body

• the conduction of information from the spinal cord

• the interpretation of messages from motor neurons
