Dry Bones SET 1: The body found behind the old cathedral in Spain is an adult male. That is because a body with a sub pubic angle of less than 90 degrees is a male. This person is an adult because the sutures of his skull have completely fused. This person also had scoliosis because that is what having a lateral curvature to your upper thoracic vertebrae indicates along with having a very small scapular spine on the left side and a very large scapular spine on the right side.

Osteoporosis‚ meaning porous bones‚ is the most common metabolic bone disease with over 10 million diagnoses in the United States of America.1 Another 34 million people are affected by osteopenia‚ the early stages of osteoporosis.1 Osteoporosis decreases bone mass and also causes micro damage to bone structure‚ increasing the likelihood of fracture and other injuries. There are two classifications of osteoporosis: primary and secondary (primary being the most common type). It affects people of all

Among the mandibular bone fractures‚ condylar region is the most frequent site accounting for about 25-35 %.1 Condylar fractures are usually the result of a direct blow to the chin or to the lateral side of the jaw caused by Road traffic accidents‚ violence‚ accidental falls and sporting injuries. Injury to the mandibular condyle fracture deserves

Osteoporosis ("porous bones"‚ from Greek: οστούν/ostoun meaning "bone" and πόρος/poros meaning "pore") is a progressive bone disease that is characterized by a decrease in bone mass and density which can lead to an increased risk of fracture.[1] In osteoporosis‚ the bone mineral density (BMD) is reduced‚ bone microarchitecture deteriorates‚ and the amount and variety of proteins in bone are altered. Osteoporosis is defined by the World Health Organization (WHO) as a bone mineral density of 2.5 standard

Protection: surrounds the brain‚ spinal cord‚ and vital organs. Movement: bones are levers for muscles. Minerals: bones store calcium and phosphate. 2. Compare the axial skeleton with the appendicular skeleton. Axial: forms the long axis of the body and include the bones of the skull‚ vertebral column and the rib cage. Appendicular: consists of the bones of the upper and lower limbs and shoulders and hip bones. 3. How are bones classified? Provide examples. They are classified by their shape:

Abstract Introduction The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint‚ while the distal part of the femur articulates with the tibia and kneecap forming the knee joint. By most measures the femur is the strongest bone in the body. The femur is also the longest bone in the body.Using the AP view of the hip‚ angle formed by axis of femoral shaft and line drawn along axis of femoral neck passing through center of head of femur. At birth‚ the femoral neck

Project 1.2.3: Bone Detectives Introduction When we think of bones‚ we most often think of the way in which these hard structures support the body‚ how they work with muscles to produce movement and how they protect our internal organs. But the 206 bones of the human skeleton can also tell a story. The specific structure of your bones reveals information about your gender‚ your height‚ your age and even your ethnicity. These biological clues are often the first pieces of evidence scientists

composition of bone mostly consist of inorganic material and collagen fibers. The macroscopic structures of bone is Compact bone‚ Cancellous bone‚ Epiphysis‚ Diaphysis‚ Periosteum‚ Red bone marrow‚ yellow bone marrow‚ and the articular cartilage (Doitpoms.com). Collagen is a triple helix structured protein that is the most prominent protein in the skeletal system. Bones consist of two distinct types of bone tissue such as cancellous and cortical bone. Cancellous bone is also known as spongy bone and is located
