Metacarpals (hand bones) metersals (foot bone) and phalanges (finger and toe bone) Functions of the skeleton The skeleton is the framework of the body; it supports the softer tissue and provides point of attachment for most skeletal muscles. The skeleton provides mechanical protection for many of the body’s internal organs, redusing risk of injury to them. Skeletal bones are attached to the muscle contract they cause bone to move, packed with over 200 bones, skeletons protect, shape support and move our bodies as well as producing red blood cells in the bone
However, their function now is to maintain cellular activities of bone tissue. Osteoclasts. It is a huge cell, it form by fusing of a group of monocyte. Its membrane is folded into a ruffled border. The cell will release powerful enzyme(lysosome) and acid.
Examples of structural proteins are cytoskeleton, microtubules, microfilament, collagen, keratin, elastin, actin, and tubulin. Humans need structural proteins to live. The structural proteins in humans create our hair, tendons, fingernails, bones, and the crystalline lens of the eye. Most of the matrix of our body is produce by structural proteins. They can consist of one or a few kinds of subunits.
Bones are made up of 25% water and 75% solids which consists of cells and mineral salts (calcium and phosphorous) Bone Tissue Bone tissue is a hard dense connective tissue. It has a honeycomb type matrix internally which helps to give the bone rigidity. There are two types of bone tissue, cortical bone and cancellous bone. Bone cells develop new bone tissue and continual bone remodelling, maintaining the bones and regulation of minerals in the body. Types of bone cells include osteoclasts.
Skeletal- Skeletal muscle is a muscle that is usually attached to bone, and is connected by collagen fibers. These fibers are known as tendons. Skeletal muscle is refers to many bundles of cells known as muscle fibers(fascicles). This type of muscle is highly composed of actin and myosin filaments. These filaments are repeated, forming sarcomeres.
Epiphyseal line is area of developing tissue and everyone has at least two, one at each end of bonePeriosteum is outer membrane which contains connective tissue, nerves and capillaries. It allows blood in and out of bone and help with growth and repair (PubMedhealth,n.d). compact bone provides the strength and protection of bones. It provides strong mechanical layers which with
There are many methods to produce bio materials such as physical method, chemical method etc. By means of appropriate selection of bio materials and producing technique depending on the area of installation of biomaterials the effectiveness of bio materials can be improved. Depending on the behavior of bio materials towards host organism and their mechanical behavior, bio materials can be installed in areas such as Joint replacements, Bone plates, Bone cement, Artificial ligaments and tendons, Dental implants for tooth fixation, Blood vessel prostheses, Heart valves, Skin repair devices (artificial tissue), Cochlear replacements, Contact lenses, Breast implants, Drug delivery mechanisms, Sustainable materials, Vascular grafts, Stents, Nerve conduits, Surgical sutures, clips, and staples for wound closure, etc. Though the material is bio compatible the same material cannot be used for all the application. Commonly bones will be replaced by titanium and its alloy and composite materials.
Bones can be found all over the human body, it is basically one of the main reasons why the body functions, and every single bone in the body is needed, including the teeth. Even the animals have bones, that's how important it is to a living thing, but what makes it so important though? Keep reading to find out IMPORTANCE OF BONES TO THE BODY MOVEMENT The bones as well as the muscle of the body works together so well that they could actually sometimes identified as one and it is called the musculoskeletal system. Some of the bones are attached to the muscles, but some of them doesn't really need to be, because there are certain muscles that needs to be affiliated with the other organs like the heart as well as the digestive system. However, every muscle that has to be moved needs to have some bones in it and these bands of tissues are actually called tendons.
Proteins are complex macromolecules that are formed by elements carbon, hydrogen, oxygen and nitrogen. Proteins composed of one or more polypeptide chains of amino acids. The main functions of proteins are to structure, support, protect, make movement, catalyst, transport and make hormones in human body. In the structural role, collagen and elastin provide support for connective tissue. Actin and myosin are proteins that involved in muscle contraction and movement.
