What are the main functions of the skeletal system? Select all correct answers.

• Facilitates movement

• Supports the body

• Protects organs

• Takes in oxygen

• Excretes waste from the body

Marrow is found in the bones. What is the function of marrow in the skeletal system?

• To produce fats

• To produce calcium

• To produce cartilages

• To produce blood cells

Which statement correctly describes how the skeletal system and muscular system work together to allow for movement?

• The bone moves which pulls the tendon and muscle along with it.

• The muscle contracts and pulls the tendon which pulls the bone and allows the body to move.

• The muscle contracts and pulls the ligament which moves the bone at the joint.

• The tendon contracts which pulls the muscle and bone along with it and allows the body to move.

• There are three types of muscle tissue.

Which statement correctly describes the types?

• Cardiac muscles contract the heart. Skeletal muscles move the bones. Smooth muscles are found in the arteries and veins.

• Cardiac muscles contract the heart. Smooth muscles move the bones. Skeletal muscles are found in the arteries and veins.

• Cardiac, skeletal, and smooth muscles are all voluntary.

• Cardiac, skeletal, and smooth muscles are all involuntary.

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

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.Sensory neurons gather information in the ears. 2.Motor neurons send a response to the legs to get up and walk out the door. 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?

• 2, 1, 3

• 1, 3, 2

• 3, 1, 2

• 1, 2, 3

Breathing is a necessary process for life. It is controlled by the nervous system. You do not have to remind yourself to breathe. 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
