- Students will understand that tissues make up different systems in our bodies that perform different functions for our bodies to live.
- Students will understand that the skeletal system is the frame that gives shape, protects body systems and allows for movement.
- The main bones of a human skeleton are: skull, clavicle, ribs, humerus, radius, ulna, vertebrae, pelvis, femur, patella, fibula, tibia.
- There are 206 bones in the adult skeleton.
- The shape of a bone is related to its job in the body.
- Bones are living tissues that make red and white bloods cells.
- Students will understand that joints and connective tissue allow skeletons to move.
- There are 3 types of joints: immovable, partially movable, movable.
- There are 2 types of connective tissue: cartilage and ligaments.
- Students will understand that eating well and exercising will help bones grow strong and stay healthy.
- Healthy foods are full of vitamins and minerals that help bones grow new cells.
- Students will understand that muscles help us move, move around and move things inside us. Muscles also protect our vital organs and help us maintain our body temperature.
- There are 2 groups of muscles: voluntary and involuntary.
- Skeletal muscles are voluntary and move our bodies.
i) The main skeletal muscles are: biceps, triceps, abdominals, back extensors, quadriceps and hamstrings.
ii) Skeletal muscles move bones by contracting and relaxing.
- Cardiac muscles are special involuntary muscles in the heart.
- Smooth muscles are involuntary muscles that line organs and blood vessels that move things throughout the body.
- Students will understand that staying healthy is important.
- Exercise helps your skeletal and cardiac muscles stay strong.
- Nutritional food choices keep your smooth muscles working right.
