A thin edge of the scapula closer to the vertebral column is called the medial border. The hick edge closer to the arm is called the lateral border. The medial and lateral borders join at the inferior angle. The superior edge of the scapula called the superior border, joins the medial border at the superior angle. The proximal end of the humerus feature a rounded head that articulates with glenoid cavity of the scapula to form the shoulder joint.
It protects and maintains vital structures in their proper position, provides stability for the body, and bodys shape. Serves as resorvoir for ions such as calcium, phosphorus and magnesium and it houses the hematopoietic connective tissue in which blood cells are formed. Two functional parts. Axial- is composed of the bones of the skull thorax and vertebral column and roms the axis of the body. Appendicular skeleton consists of the bones of the upper and lower extremities, including shoulder and the hip.
calcium,) and lastly the creation of red blood cells which are used to transport oxygen around the body and to the muscles. The first function of the skeleton is protection. This is done through the clever use of flat bones and fixed joints. An example of a flat bone forming a fixed joint to serve this function is the skull, or cranium. The plates that make up the cranium and fixed into position.
Epiphyseal growth plates cause long bones grow longer. During adolescence hyaline cartilage stays between the diaphysis and epiphysis. Young chondrocytes are constantly dividing within the epiphyseal plate. New chondrocytes are created on the epiphyseal side of the plate when the bone lengthens, but the thickness stays a constant size. On the other hand, old chondrocytes are replaced by bone on the diaphyseal side, causing the length of the bone to increase.
How does this relate to osteoporosis? Bone remodeling, by definition, is a continuous process of bone resorption and formation for the purpose of maintaining normal bone mass. Normal bone mass is very good because it means you have healthy bones. Bone remodeling continues to function as long as the body is living, and helps keep your bones strong and whole. Over time, the body will wear and your bones could fracture, so the body counteracts by creating new bone in place of the old broken bone.
A joint is the location at which two or more bones make contact. They are constructed to allow movement and provide mechanical support and weight bearing. 2. What is a synovial joint? Synovial joints are made up of bones that come together to formulate the joint, the ligaments attach bone to bone and allow for the joint movement to be stable and in the correct direction.
The skeleton system has two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton consists of the skull, the spine, the ribs and the sternum (breastbone) and includes 80 bones. The appendicular skeleton, consisting of 126 bones, includes two limb girdles (the shoulders and pelvis) and their attached limb bones. Bones have two main purposes which are for you to stand correct instead of lying down on the floor like puddle of skin/mud. Other bones protects the delicate and sometimes the soft parts of your body.
Injuries to the growth plate are called fractures. During fracture healing, cartilage is often formed called callus. This cartilage ultimately develops into new bone tissue through the process of endochondral ossification. Ossification process can be studied in the long bones, such as the bones of the limbs. In an adult long bone can be distinguish grossly by a cylindrical shaft or diaphysis of compact bone.
This surgery is done to relieve pressure on the spinal cord or spinal nerve roots caused by age-related changes in the spine. It also is done to treat other conditions, such as injuries to the spine, herniated discs, or tumors. In many cases, reducing pressure on the nerve roots can relieve pain and allow you to resume normal daily activities. Laminectomy removes bone (parts of the vertebrae) and/or thickened tissue that is narrowing the spinal canal and squeezing the spinal cord and nerve roots. This procedure is done by surgically cutting into the back.
