Control and Coordination Quiz

What is the main function of the nervous system?

• Transmit signals between different parts of the body

• Digest food

• Produce hormones

• Regulate body temperature

How does the nervous system help us to respond to our surroundings?

• By controlling the digestive system

• By regulating body temperature

• By producing hormones

• By receiving information from the environment, processing it, and sending signals to the muscles and glands to take appropriate actions.

What are the three main parts of the human brain?

• heart, lungs, liver

• stomach, intestines, kidneys

• spine, ribs, skull

• cerebrum, cerebellum, and brainstem

What is the function of the cerebrum in the human brain?

• Controlling heart rate

• Regulating body temperature

• Digesting food

• Higher brain functions such as thinking, perception, and voluntary actions

What are the two types of nerves in the human body?

• Left nerves and right nerves

• Sensory nerves and motor nerves

• Brain nerves and spinal nerves

• Fast nerves and slow nerves

Explain the difference between sensory and motor nerves.

• Sensory nerves carry information from the muscles to the brain, while motor nerves carry information from the brain to the senses.

• Sensory nerves carry information from the senses to the brain, while motor nerves carry information from the brain to the muscles and glands.

• Sensory nerves carry information from the brain to the muscles, while motor nerves carry information from the senses to the brain.

• Sensory nerves carry information from the brain to the senses, while motor nerves carry information from the muscles to the brain.

What is a reflex action?

• A reflex action is a learned behavior in response to a stimulus

• An involuntary and nearly instantaneous movement in response to a stimulus

• A planned and deliberate movement in response to a stimulus

• A reflex action is a type of voluntary movement in response to a stimulus

Give an example of a reflex action.

• Jumping in response to a loud noise

• Sitting down when feeling tired

• Sneezing when smelling pepper

• Blinking in response to a sudden bright light

How does a reflex action help to protect the body?

• By allowing for quick and automatic responses to potential harm or danger.

• By causing delayed and slow responses to potential harm or danger

• By increasing the risk of injury and damage to the body

• By allowing for conscious and voluntary responses to potential harm or danger

Explain the pathway of a reflex action in the body.

• Sensory neuron to brain to motor neuron to effector organ

• Motor neuron to spinal cord to sensory neuron to effector organ

• Sensory neuron to spinal cord to motor neuron to effector organ

• Effector organ to motor neuron to spinal cord to sensory neuron
