skeletal system
Mechanical. Support. Bones provide a framework for the attachment of muscles and other tissues. ...Protective. Bones such as the skull and rib cage protect vital organs from injury. Bones also protect the marrow.Metabolic. Mineral storage.

  • 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.

Diseases and disorders associated with the body system

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 !!!!!!

  • 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.
  • The axial skeleton part of the human skeleton has 80 bones. It includes the vertebral column, the rib cage and the skull and helps us maintain our upright posture, by spreading the weight in the head, and upper areas down to the lower areas near the hips.
  • The appendicular skeletal section of our skeleton has 126 bones. It includes the pectoral (shoulder) girdles, the pelvic girdle and the bones of the lower and upper limbs. Its function is for movement of the body and to protect some organs.
