Chapter 6 The Skeletal System: Bones and Joints PART I * A born baby has about 276 bones while an adult has 206 bones‚ this is because as you grow some bones join together in a single bone. * Bones are 20% of your weight. * The Skeletal System consist of: * Bones * Cartilages * Tendons * Ligaments * Joints * Functions of the skeletal system -bones perform various anatomic (mechanical) & physiologic function. They: 1. Stabilize‚ provide shape & support the

body. Levers: The system uses the bones with joints to provide movement to the body. The bones are held together by ligaments and tendons. The tibia and femur act as levers so a footballer can kick. Attachment: Bones provide a surface that the muscles can attach to‚ forming the human shape. A material called periosteum provides a surface that muscle tendons attach to. Protection: The skeleton encases organs in hard bones to stop them being damaged easily. Bones such as the cranium and ribs protect

The Skeletal System The skeletal system is made up of bones‚ the joints where bones meet‚ and the connective tissues called cartilages that hold the bones together. The human skeleton is made up of 206 bones‚ and can be divided up into to two parts‚ the Axial Skeleton and the Appendicular Skeleton. (Adams et al.‚ pg. 4)(Boundless‚ 2013) Axial Skeleton The axial skeleton forms the main axis or core of the skeletal system. It consists of the skull‚ vertebral column‚ and thoracic cage. As noted by

Osteoporosis Case Study Brittany Laplow Bone Physiology Question 1 Describe bone physiology and the bone remodeling cycle. Be sure to emphasize the two types of bone tissue and the roles of osteoblasts and osteoclasts. Bone physiology is the growth and repair of bones. Bone remodeling is part of this cycle. There are two parts of this cycle‚ bone deposit and bone resorption (Marieb & Hoehn‚ 2013). Bone deposit marks areas that need repairing by osteoblasts and bone resorption removes osseous tissue by

state‚ and a dry state. The bones that were burned in a green states were easily recognized by the pronounced attachment of flesh to the bones and the fresh appearance of the remains‚ whereas the dry state didn’t have any flesh attached and was just bones (Ubelaker‚ 2008). Forensic anthropologist could also differentiate between the two types of burning states through the external changes that occurred to the bones as they were burned. In the green (fleshed) state‚ the bones displayed transverse fractures

Synarthroses joints come together at a point at which adjacent bones are bound by collagen fibers that emerge from the matrix of one bone‚ cross the space between them‚ and penetrate into the matrix of the other. c. Syndesmoses are functionally a bit different. They are classified as amphiarthroses. Explain why. Amphiarthrosis is a type of continuous‚ slightly moveable joint. In syndesmoses‚ the fibers are longer and the attached bones are more movable. There is a greater distance between the articulating

The Aging Musculoskeletal System When the bones lose mass and become brittle it is called osteoporosis. Loss of bone density accelerates in women after menopause. Mrs. Smith is an 84 year old thin‚ small boned woman. Muscles‚ bones and joints are affected by the ageing process. Osteoarthritis‚ osteoporosis and rheumatoid arthritis are more common in older people. Exercise to increase muscle and bone fitness can reduce or reverse the risk of disability and disease. Some age-related changes‚ such
