The skeletal system is a system made up of bones. Bones are made up of collagen, calcium, phosphorus, and magnesium. Calcium, phosphorus, magnesium are minerals that make bones hard. A newborn baby has about 300 bones and an adult has about 206 bones. Without the skeletal system, you would be a blob on the floor. You wouldn’t be able to stand, walk, talk, or move. Muscles are attached to your bones by a connective tissue called tendons. The muscles and bones work together to help you move and provide structure. The bones in the skeletal system also protect important parts of your body such as your heart and brain. Without any bones, you wouldn’t be able to survive.
There are many bones in your body. The skull protects your brain and eyes. The mandible is the jaw bone. Bones that make up the spine are called vertebrae. The bones protecting the chest cavity and the heart are called ribs. The clavicle is the collar bone, and the scapula is the shoulder blade. The humerus is the top of the arm, the ulna is the little finger side of the lower arm, and the radius is the thumb side of the lower arm. The wrist bones are called carpels, the palm of the hand is called the metacarpals, and the fingers and toes are called phalanges. The coxa bones are the hip bones. The femur is the thigh bone, the patella is the knee cap, the tarsals are the heel bones, and the metatarsal is the arch of the foot. These are some of the main bones in your body.
There are a lot of problems and diseases that occur in the skeletal system. One of the most common disease is arthritis. Arthritis is an inflammatory condition that affects joints such as your knees, or a part of your spinal column. Some of the symptoms when you have arthritis are joint pain, swelling and stiffness, reduction in the ability to freely move your joints.
Another disease that occurs in the skeletal systems is called osteomalacia. Osteomalacia is a disease that leads to softening and weakening of the bone tissue. This disease is caused by prolonged vitamin D deficiency.
