Hyaline cartilage thinly covers the articulating ends of bones, connects the ribs to the sternum, and supports the nose, the trachea, and part of the larynx. It is covered by a membranous perichondrium, except where it coats the ends of bones, and tends to calcify in advanced age PERIOSTEUM- a thick, fibrous vascular membrane covering the bones, except at their extremities. It consists of an outer layer of collagenous tissue containing a few fat cells and an inner layer of fine elastic fibers. Periosteum is permeated with the nerves and blood vessels that innervate and nourish underlying bone. The membrane is thick and markedly vascular over young bones but thinner and less vascular in later life.
In the periosteum it surrounds the bone surface wherever it is not covered by articular cartilage, it is a sheath of dense irregular connective tissue containing osteoblasts, it functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serves as an attachment point for ligaments and tendons. 4- Which kind of bone marrow is in spongy bone tissue? Red bone marrow is the type of marrow found in spongy bone tissue. 5- Which ossification method would form a femur? Endochondrial ossification would form the femur.
Which ossification method would form a femur? The femur, which is a long bone, is formed by endochondral ossification which is the replacement of cartilage by osseous tissue. most of the long bone body are formed by this process. 6. Why is bone remodeling necessary when a person reaches adulthood?
Definition: Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and have a complex internal and external structure, are lightweight yet strong and hard, and serve multiple functions. One of the types of tissue that makes up bone is the mineralized osseous tissue, also called bone tissue, that gives it rigidity and a coral-like three-dimensional internal structure.
Short, flat, and irregular bones consist mainly of spongy bone tissue, except at the surface, where there is compact bone. Compact bone tissue contain less spaces and forms the external layer of all bones. Compact bone tissue provide protection and support, it also resists the stresses produced by weight and movement. Compact bones are arranged in repeating structural units called osteons. Spongy tissue bones does not contain osteons.
The human skeleton Is made up of 206 bones. The functions of the skeleton are to provide support, give our bodies shape, and provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement Joints A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilagenous (partially moveable) and the Synovial (freely moveable) joint. Fibrous joints Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.
Unit 4222-232Move and position individuals in accordance with their plan of care (HSC 2028) 1.0 Understand anatomy and physiology in relation to moving and positioningindividuals 1.1 Outline the anatomy and physiology of the human body in relation to the importance of correct moving and positioning of individuals Bones and muscles are concerned with the movement of the body. The skeleton is a rigid framework that gives shape and support to the body and is jointed to permit movement. The vertebral column is the basis of the skeleton and consists of a series of bony rings united by inter-vertebral discs of cartilage. All bones give attachment to muscles, which are responsible for 50% of our body weight and also permit movement. Bones are moved at joints by contraction and relaxation of the muscles attached to them.

-tendons attach muscles to the bones - cartilage protects bones within joints. - synovial fluid: acts as lubricant - synovial membrane: secretes synovial fluid - ligament: joins bone to bone and is strong and flexible - muscle - fibrous capsule: encloses joints - pad of cartilage: gives additional protection - cartilage: absorbs synovial fluid and acts as shock absorber - bone - tendon: joins muscle to bone At a joint there is: Joints and movement continued 2 of 60 1 of 60 How do muscles work? - muscle is made up of bundles of muscle fibres, each fibre is a single muscle cell - each muscle cell is multinucleate (has more than one nucleus) this is because a single nucleus could not effectively control the metabolism of such a long cell. - Tendons connect muscle to bone - the muscle is made up of bundles of muscle fibres. these are bound together by connective tissue.
Skull Fracture The skull is made up of many bones that form a solid container for the brain. The face is the front part of the head and also helps protect the brain from injury. Depending
