I agree with Mary Kern about bones. The development of bones comprises of three processes bone modeling, bone growth, and bone remodeling. The three processes occur at various stages in an individual’s life. There are three kinds of bone cells osteocytes, osteoclasts, and osteoblasts. The cells comprise the living component of the bone. In addition, the cells play a critical role in bone remodeling (Plowman & Smith, 2014).

I agree with Kim Pappas about the difference in anatomic location and purpose of bursa, tendons and ligaments. The ligaments are structures of fibrous, dense connective tissue. In addition, they link the aspects of the bony skeleton and other body organs. The purpose of ligaments is to increase the mechanical strength of the joints, prevent strenuous movement and direct motion. The tendons attach muscle to bone and transport tensile loads from muscle to bone, generate joint movement and preserve the body posture. The bursae are flattened sacs consisting of a synovial membrane that has a capillary film of synovial fluid. They are situated at the underlying bone and deeper skin layers between bone, tendons, and independent muscles. Their function is to create a protective sleeve around the tendon (Watkins & Mathieson, 2009).

I agree with Sheila Eidson about ligaments, tendons, and bursae. The ligaments and tendons comprise fibers of fibrous type I collagen. They are mostly parallel-fibred, dense tissues. The tendons link muscle to bone and give a rigid passive channel for the conveyance of force. The ligaments, on the other hand, strengthen the joint capsule and give passive solidity to the joint. The bursae is a synovial structure that surrounds tendons and joints in particular positions to permit freedom of motion and normal limb movement. A recurrent pressure or trauma on bursae results in inflammation that causes olecranon bursitis (Ma & Elisseeff, 2005).
