Muscular System
What is the purpose of the muscular system? The main function of the Muscular System is movement, body posture and
position. It is the only tissue in the body that has the ability to contract and therefore move the other parts of the body.
What are the 3 muscle types and describe each?
Muscle Type
Voluntary or Involuntary
Example
Skeletal
Voluntary Muscle
Arm Muscle
Smooth
Involuntary Muscle
Stomach
Cardiac
Involuntary Muscle
Heart
What happens to your muscles when you have a lack of sufficient oxygen? Muscles will cramp.
What is a voluntary response? In order for these responses to happen, you have to think. Some examples are smiling, wiggling
toes, frowning, lifting your arms, moving your legs, etc.
What is an involuntary response? Involuntary responses are automatic and no thinking is required. Some examples are
heartbeat, blood pressure, breathing rate, etc.
Nervous System
What is the purpose of the nervous system? The Nervous System analyzes incoming information from outside the body, store
it, and send back instructions to various parts of the body so the body can respond.
What are the 3 main parts of the nervous system?
1) The Brain
2) The Spinal Cord
3) A Network of Nerves
What are the 3 main parts of the brain and describe each part?
1) Cerebrum is the largest part of the brain and controls the sense organs, along with your thoughts, memories, imagination,
and the decisions you make.
2) Cerebellum controls your balance and posture, and coordinates your movement.
3) Brain Stem connects the cerebrum to the cerebellum and to the spinal cord.
What are the five types of sense receptors and describe each?
**Sense Receptors provide the brain with information by detecting what’s happening outside the body.
1) Sense of sight
2) Sense of hearing
3) Sense of smell
