HUMOR-ous+Bones

media type="custom" key="9016982" The skeletal system is all of the bones in the body. There are 206 bones in an adult human body. The skeletal system provides shape and support, enables you to move, protects your organs, produces blood cells, and stores minerals and other materials until your body needs them. At the end of the bones are cartilage. Cartilage keeps the bones in shape and supports the bones. Bones are hold together by joints. A joint is a place in the body where two bones come together. There are four types of joints: a Gliding Joint, Ball and Socket Joint, Hinge Joint, and Hinge Joint.

There are also diseases and injuries of the skeletal system. These diseases are Osteoporosis, arthritis, dislocations, sprains, simple fractures, and compound fractures. Compound fractures are worse than simple fractures. Osteoporosis is when bones become weak and can break easily. Arthritis is when pain and stiffness in joints. Sprains are when ligaments are torn. Dislocations are when bones pop out of their place. Fractures are when your bones break or crack. Two ways to identify bone injuries are X-rays and MRI (Magnetic Resonance Imaging). X-rays are a form of energy that travels in waves. MRI is a more recently developed method for taking clear images of both the bones and soft tissues of the body. There are three ways to treat bone injuries. The simplest one is to wear a cast. Two other ways are to have surgery and/or arthroscopy.

The best way to keep bones healthy is to be on a healthy diet and exercise. Like you could play a sport every other day or take a jog around the block. It keeps your bones strong so that you can stay away from some diseases. You also need calcium from dairy products. This also keeps your bones strong.

Bones are complex living structures that undergo growth and development. A thin, tough membrane covers all of a bone except the ends. Blood vessels and nerves enter and leave the bone through the membrane. Beneath the membrane is a layer of compact bone, which is hard and dense, but not solid. Just inside the compact bone is a layer of spongy bone, which which has many small spaces within it. The spaces in bone contain a soft connective tissue called marrow. There are two types of marrow, red and yellow. Red bone marrow produces blood cells. Yellow bone marrow stores fat that serves as an energy reserve.

Skull- The cranium is the part of the skull that encloses the brain

Clavicle- the collar bone

Scapula- The shoulder blade

Sternum- The breastbone

Humorous- The upper arm bone

Ribcage- It protects internal organs such as the heart and the lungs

Vertebral column- The backbone. The backbone is made up of 26 small bones, or vertebrae.

Radius- The thicker and the shorter of the two bones in the forearm

Ulna- The thinner and longer of the two bones in the forearm

Carpals- any of the eight small bones forming the wrist

Metacarpal- any of the five bones of the hand

Phalanges- the bone of the finger or toe

Tarsal- a group of small bones between the main part of the hind limb and the metatarsals

Metatarsus- group of bones in the foot

Pelvis- the large bony structure near the base if the spine to which the hind limbs or legs are attached in the humans and many other vertebrates

Femur- the bone of the thigh or upper hind limb

Patella- kneecap Tibia- the inner and typically larger of the two bones between the knee and the ankle

Fibula- the outer and usually smaller of the two banes between the knee and the ankle in in humans
