Dec 21, 2018· We've got the skin covered, so now let's take a look at bones! These give structure to the body. Bone is a type of tissue, but an actual complete bone is an organ, because there is lots of stuff ...

Chapter 1 - Bone, Basic Principles A. Structure and Composition. The shapes of individual bone are genetically determined, but biomechanical forces induced by muscle pull, gravity, and joint function modify the structure in health and disease. 1. Microanatomy. Osseous tissue is a special type of connective tissue.

Bone, rigid body tissue consisting of cells embedded in an abundant hard intercellular material. Bone tissue makes up the individual bones of the skeletons of vertebrates. Its two principle components are collagen and calcium phosphate. Learn more about the composition and function of bone.

Aug 04, 2010· Bone Production: Your body will start to replace the clotted blood with soft cartilage tissue and, later with hard bone tissue. Bone Remodeling: This phase lasts several months to several years. Bone continues to form and solidify, and blood circulation returns to the formerly fractured area .

Within about 48 hours after the fracture, chondrocytes from the endosteum have created an internal callus (plural = calli) by secreting a fibrocartilaginous matrix between the two ends of the broken bone, while the periosteal chondrocytes and osteoblasts create an external callus of hyaline cartilage and bone, respectively, around the outside of the break (Figure 6.21b).

Bone fractures happen when a bone is damaged by stress.The bone can be fractured in many different ways.. Most human bones are strong and do not break when hit by strong impacts or forces. However, if that force is too powerful, or there is something wrong with the bone, it can fracture.

Shaft or middle region of long bone that contains layer of spongy bone. Epiphysis. the end of a long bone, initially separated from the main bone by a layer of cartilage that eventually ossifies so the parts become fused. Metaphysis. growth zone between the epiphysis and the diaphysis during development of a long bone.

Bone tissue (osseous tissue) is a hard tissue, a type of dense connective tissue.It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells. Osteoblasts and osteocytes are involved in the formation and mineralization of bone; osteoclasts are involved in the resorption of bone tissue.

A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of the bone.In more severe cases, the bone may be broken into several pieces. A bone fracture may be the result of high force impact or stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis ...
