skeletal system Flashcards
What are the five functions for the skeletal system
- Storing Minerals
- Protection
- Blood cell production
- Muscle Attachment
- Joints for movement
How does the skeletal system protect vital organs
Bones can act as cages around important body parts. For example the skull protects the brain, rib cage protects the internal organs including the heart etc. Some sports require extra protection for the safety of the players such as a helmet.
How does the body use the skeletal system for muscle attachment
The bones acts as anchors for the muscles to pull on
How does the body use the skeletal system for joints of movements
Joints allow the body to move in a range of different ways. Joints works with muscles and bones to form levers.
How does the body use the skeletal system for storing minerals
The skeletal system acts as a store for minerals such as calcium and phosphorous. These are minerals that are vital for developing and maintaining strong, healthy bones.
How does the body use the skeletal system to produce red and white blood cells
Some bones have hollow centres that hold bone marrow. Bone marrow makes most of the blood cells in your body. Bone marrow responds to your activity and condition to keep you in good shape. When the amount of red blood cells in your body drop your bone marrow makes more red blood cells.

What are the classification of bones
- Flat bone
- Irregular bones
- Short bones
- Long bones
What are long bones
Long bones are longer than they are wide.All limb bones apart from the kneecap are long bones. These bones are vital to aid movement in sports.
What are short bones
Short bones are all roughly the same size in length, width and thickness. Short bones are usually associated with weight bearing, shock absorption and spreading loads. The only short bones are in the carpals and tarsals.
What are flat bones
Flat bones usually protect organs and offer good surface for muscles to attach to.
What are irregular bones
Irregular bones have odd shapes and perform a range of functions. An example is the spine. This bone is meant to be irregular as it protects the spinal cord.
What is cartilage
A firm connective tissue
What is the vertebral column
