Skeletal Cartilage

Skeletal Cartilage contains no blood vessels or nerves.

            3 different kinds:

 1.Hyaline
    The most abundent skeletal cartilige and it provides support, flexiblity, and resilience.  

         -Articular- covers the ends of long bones.

         -Costal- connects the ribs to the sternum.

         -Respiratory- Makes up the larynx and rienforces air passages. 

         -Nasal- supports the nose

     

 2.Elastic

      Elastic cartilage is similar to hyaline but contains elastic fibers. For example the epiglottis. 

 3.Fibrocartilage
       Fibrocartilage is compressed with great tensile strength contains collagen fibers. Such as the menisci of the knee and intervertebral discs.

The purpose of cartilige is to protect the bones and joints. Cartilage keeps the bones and joints from rubbing against each other. In other words cartilage keeps the bones and joints strong.

Bones

The functions of the bones is to support, protect, movement, mineral storage, and blood cell formation. The bones start to form at eight weeks of embryo. They develop from fibrous membrane and form by replacing hyaline cartilage. Bones still are forming through early childhood.
