Unit 5 Reading Guide Questions Which minerals are stored in bones? Triglycerides‚ calcium phosphate‚ and calcium hydroxide are all stored in the bones as mineral salts Which types of bones provides a large‚ flat surface area for muscle attachment? Flat bones such as the scapulae have large‚ flat surface area for muscle attachment. Describe the location‚ composition‚ and function of the epiphyseal plate. The epiphyseal plate is located in the metaphysis‚ and is composed of hyaline cartilage

Osteogenesis Imperfecta (OI) is known as brittle bone disease‚ and is a genetic disorder in which an individual has weakened bones that may fracture in situations of minor to inexplicable trauma. OI spans from a slight degree to the more critical cases which may lead to death moments after their delivery or prior to their existence (“Learning About Osteogenesis Imperfecta‚” 2012). No two people suffering from this condition share the same measure of difficulty. In fact‚ though there are various forms

~Cross-section of a bone~ Articular cartilage - is a white‚ smooth tissue which covers the ends of bones in joints. Periosteum - is a fibrous sheath that covers bones. It contains the blood vessels and nerves that provide nourishment and sensation to the bone. Cortical bone - forms the outer shell of all bone and also the shafts in long bones. Trabecular bone - is the tissue that makes up the interior of bones.

ABSTRACT Osteogenesis Imperfecta Dominant and Recessive Pattern Background Osteogenesis Imperfecta (OI) is heterogenous genetic disorder in the type I collagen and is characterized by susceptibility bone fragility and fractures with variable severity and presumed or proven defect in type I collagen biosynthesis. Type I collagen is the abundant protein composing the extracellular matrix of bone and skin in human body. There are 3 pathogenesis mechanisms of OI: 85-90% of individuals with OI

Bones support‚ move‚ and protect the body; they also give us our features. But without bone cells we would have no bones. Bone cells are the living units that make up your bones and keep them functioning. Bone cells have two major roles‚ which are the production of new bones and resorption or destruction of old bone. They also carry out other small roles. There are four main types of bone cells: Osteogenic‚ which are bone cells that respond to traumas‚ osteoblasts‚ which form bone matrix around themselves

Thoracic Outlet Syndrome (TOS) is used to describe upper extremity symptoms and according to recent reports 1‚2 is defined as compression of the neurovascular structures in the interscalene tri-angle‚ as it exits the thoracic girdle. The bony anatomy of thoracic outlet‚ which will be discussed in further detail‚ can be defined by the space between the first thoracic vertebra‚ first rib‚ and manubrium of the sternum.1 Thoracic Outlet Syndrome is not specific in determining the struc-ture being compressed

There are 7 different limb bones in the skeleton. The humerus in both arms are the longest bone in both arms. A lot more powerful bones that manipulate the upper arm just at the shoulder‚ at the elbow are all situated for the humerus.(8) The radius is the shorter of the two bones in the forearm. The radius is located on the thumb side of the forearm and allows rotation to allow to the hand to move about at the wrist.(9) The ulna is one of the most important bones to the form arm as it does give

Perthes Disease Perthes Disease‚ also known as Legg-Calve Perthes Disease is a childhood disorder that affects the head of the femur bone‚ where it connects to the hip bone. Begins in childhood and affects boys more than girls between the ages 4-8 and is more common in Caucasian children than those of an ethnic back round. Usually it only affects one hip‚ but in 10% of some cases it affects both. This is not an infectious disease‚ so other children in the house won’t be affected. It occurs when
