Structure of the shoulders allows movement of the arm in usally any direction but provides little stabilty. The glenohumeral joint is proe to dislocation that is why usually held in place primarily by muscular and ligament attachment with little bony stability. 1. Humerus and scapula 2. The structure of the shoulder permits movement of the arm in almost any direction but provides little stability. The glenohumeral joint is prone to dislocation because it is held in place primarily by muscular and ligament attachment with very little bony stability.

Your Answer: Greenstick A Greenstick fracture occurs when the bone bends and breaks, but not all the accross. It occurs commonly in children because the bone tissue is still devoloping and soft on them. Greenstick (the bone is broken, but not all the way across) Question 21 5 / 5 pts A patient has a diagnosis of osteoporosis. (1) In your own words, describe this diagnosis and (2) What type of bone cell would they be lacking? Explain your answer. Your Answer: 1. Osteoporosis is a bone tissue. If the bone tissue degenerates faster than is replaced, bones may be weak by times. Brittle bones might be cause increased pain and likely to fracture. 2. They'd have decreased osteoblast that are responsible for the bone repair. And basically when bone repair would be keep up the ongoing breakdown of bone that is done through work of osteoblasts. (1) Osteoporosis is a bone tissue disease. When bone tissue degenerates faster than is replaced, the bones become weak. Brittle bones cause increased pain and are more likely to fracture. (2) They would have decreased osteoblasts which are responsible for bone repair. The bone repair would be unable to keep up with the ongoing breakdown of bone which is done by the work of osteoblasts. Question 22 5 / 5 pts Your patient has back pain due to a herniated disc. (1) In your own words explain what it means to have a herniated disc. (2) As reviewed in the module, discuss one treatment option to address your patient’s pain. Your Answer: Herniated disc is when the disc between the vertebrae slips and presses on the spinal cord and nerves. It causes pain. This situatition may be treated in a few different ways. One form is physical therapy in get strentght the muscles area. Surgery is an option resulting in removing the disc yet having to fuse together the vertebrae. (1) A herniated disc is an injury to the intervertebral disc, where the center portion of the disc bulges into the vertebral foramen, causing pain. (2) Explanation of 1- Physical therapy for strengthening to support back ligaments. OR 2- Surgery to fuse two vertebrae together.
