It is covered in cartilage
Because that is where it comes into contact with other bones and provides a low friction protective covering allowing for smooth painless movement of joints of the bones.
Flat bones
cranium
Periosteum is the membrane that lines the outer surface of all bones, except at the joints of long bones.
Calveria is a generic name for the bones covering the brain. The type of bone is compact bone.
My doctor told me that I had an inflammation of the periosteal membrane covering the femur in my right leg. Peri- means around and osteal refers to bone. The periosteum is the membrane that is around and covering all bones except those in joints.
The human body covering is the skin. The skin is the largest organ in the human body and is a protective covering for the bones, muscles and organs.
No bones are joints.
Periosteum is a membrane that lines the outer surface of all bones,[1] except at the joints of long bones.
Hyaline cartilage normal covers the articular surfaces of bones in typical synovial joints and primary cartilaginous joints. Certail joints do not have hyaline cartilage covering the bony elements. These include: 1. Fibrous Joints - skull sutures, gymphosis (teeth) and interosseus joints (radius and ulna shafts) 2. Atypical Synovial Joints (these have fibrocartilage instead of hyaline cartilage covering the bones). These include the Temporomandibular (TMJ), Acromioclavicular Joint (ACJ), Sternoclavicular Joint, and 2nd to 7th Sternocostal Joints.
The cartilage is a protective covering which encases a lubricating fluid, to prevent damage to the bones caused by friction.If you didn't have any cartilage in your joints your bones would not stay in place they would just fall out and if they didn't u would be in extrem pain constantlyCartilage prevents the ends of bones from rubbing on each other. Without cartilage, walking would be very painful.
Joints. The joints connect the bones into place, so it is your bones that hurt when you get bad joints in old age.
