The Skeletal System
The skeletal system makes up the framework of the body and allows us to move when our muscles contract. It stores minerals (e.g. calcium, phosphorous) and releases them into the body when they are needed. The skeletal system also protects internal organs and produces blood cells.
- Bones provide calcium that is essential for the proper functioning of the nervous system.
- The skull protects the brain from injury.
- The vertebrae protect the spinal cord from injury.
- Sensory receptors in joints between bones send signals about body position to the brain.
- The brain regulates the position of bones by controlling muscles.
Osteoporosis is a prevalent disease of the skeletal system, particularly among the elderly, resulting in the loss of bone tissue. In osteoporosis, bone loses calcium, becomes thinner, and may disappear completely.
Also common is scoliosis, a side-to-side curve in the back or spine, often creating a pronounced "C" or "S" shape when viewed on an x-ray of the spine. This condition is typically becomes evident during adolescence.
Arthritis is a group of more than 100 inflammatory diseases that damage joints and their surrounding structures. Arthritis can attack joints, joint capsules, the surrounding tissue, or throughout the body. It usually affects the joints of the neck, shoulders, hands, lower back, hips, or knees.
5 FUN FACTS !!!!!
an adult skeletal system has 206 bones
an adult skeletal system consists of 32 teeth
- At birth the human skeleton is made up of around 300 bones. By adulthood, some bones have fused together to end up with 206 bones.
- Human bones grow continually from birth till our mid 20's. Our skeleton's bone mass is at its maximum density around the age of 30.
- If broken our bones will re-grow and repair themselves. Often doctors will place a cast on splint to make sure these bones repair straight and true.
