The Skeletal System
What are the main components of the skeletal system?
Bones and joints.
What is the main organ in the muscular system?
Muscles.
What are the two major divisions of the nervous system?
The central and peripheral nervous systems.
What is alcoholism?
Alcoholism is an addiction to alcohol.
How do muscles move in pairs?
Muscles expand and contract.
What are joints and what is their function?
Joints are where two bones meet. Most joints allow movement.
How can we take care of our muscular system?
Consuming a healthy diet, performing regular exercise, and getting sufficient rest.
What if a child put their hand on a hot stove?
Their peripheral nervous system would cause them to perform an immediate reflex and remove their hand from the stove.
What effects does alcohol have on the stomach?
Alcohol can cause gastritis and the formation of stomach ulcers.
1) Irregular bone
2) Long bone
3) Flat bone
1) Irregular bone - bones of the face
2) Long bone - femur
3) Flat bone - ribs
What bones protect the following the vital organs:
1) Heart and lungs
2) Spinal cord
3) Brain?
1) The rib cage protects the heart and lungs.
2) The spinal column or spine protects the spinal cord.
3) The cranium protects the brain.
Describe what happens when you bend your arm.
What are the five main organs of the nervous system?
Double Points: Name their functions.
1) The brain is responsible for memory, thought, and emotional regulation.
2) The cerebellum coordinates voluntary muscle movements and balance.
3) The brain stem regulates involuntary muscle movements.
4) The spinal cord communicates information between the nerves and brain.
5) The nerves receive information via the five senses; they are involved in reflexes.
1) The mouth
2) The liver
The quadriceps, gastrocnemius, and gluteus maximus are part of this body system.
The muscular system.
Give 1 example each of movable, partially movable, and immovable joints.
Movable - shoulder
Partially movable - hips
Immovable - the joints in between the plates of the cranium
Name 3 involuntary muscle movements.
1) Breathing
2) Heart beating
3) Digestion
What would happen if you damaged your cerebellum?
You could have difficulty balancing or maintaining your posture.
The brain.
What would happen if you broke your radius and ulna?
You would likely be unable to move your arm.
What are the three functions of the skeletal system?
1) To allow movement
2) To protect the vital organs
3) To give the body shape and structure
How do the skeletal and muscular systems work together?
Our bones, joints, and muscles work together to allow movement.
Create a situation explaining the three steps of a nervous system response.
Ex. A child wants to cross the street when they reach an intersection. 1) Through the sense of sight, the child receives the information that there are cars driving in front of them. 2) The nerves in the child's eyes send messages to their brain via the spinal cord to process the information. 3) The child reacts by stopping and waiting on the sidewalk instead of walking into moving traffic.
1) Engage in regular physical activity.
2) Become informed about the dangers of alcohol abuse.
3) Spend time with your family and friends.
What do tendons connect?
What do ligaments connect?
Bonus: Why are they important?
Tendons connect muscles to bones.
Ligaments connect bones to bones or cartilage.
Bonus: Tendons and ligaments are important because they keep our bones and muscles in place, limiting potential damage to our musculoskeletal system.
