Most of our skeletal muscles are attached to bone on either end by tendons. As the muscles contract‚ they exert force on the bones. This force helps to support and move our body. Normally one end of the muscle is fixed in its position and the other end moves during contraction. The Origin is the attachment site that is stationary during contraction. The insertion is the site that does move when a muscle contracts. When we discuss the position of the Origin and insertion points‚ the insertion

system. The skeletal system is made up of bones which have an outer hard cortical layer and an inner soft trabecular layer made of cancellous bone. Within some long bone is the all important marrow from where all the blood cells originate after maturation. The skeletal system can be divided into 2 groups: 1. Axial skeleton: The bones here include the skull and bones of the vertebrae column. The skull is subdivided into the 8 cranial bones and 14 facial bones‚ while the vertebrae column is made up

Muscles work like leavers and this allow the bones at a joint to work like hinges. When moving someone it is important to remember that the muscles can only move the joint as far as the bone will allow them. 1.2 Describe the impact of specific conditions on the correct movement and positioning of an individual.

The Aging Musculoskeletal System Bone and muscle health and maintenance are important in aging adults. However‚ it is especially imperative for elder Caucasian women to have good bone and muscle health. Not maintaining strong bones can lead to bone diseases‚ such as‚ osteoporosis and osteoarthritis. Poor muscle health can result in muscular atrophy. For example‚ Edith‚ who is an 84-year-old thin‚ small boned‚ white female suffers from all three of those diseases. Osteoporosis is a disease characterized

It will also eventually dictate what our general physical make-up will be once we reach full adulthood. There are two-hundred and six bones in the human body. Most people think we need to grow and reach full adulthood before we have the two-hundred and six‚ but the truth is that when we are born‚ we have all of these bones‚ only they are less dense and

Review Questions 1. What are epiphyseal fusions? What can they tell a forensic anthropologist? – Epiphyseal fusion is the fusion‚ and/or the closing of the ends of “growth plates”‚ or at places like the clavicle‚ iliac crest‚ and the long bones in our arms and legs. 2. What is ethnobotany? Why is this area helpful for forensic anthropologists? – Ethnobotany is the study of plant remains and pollens. I’d imagine that this would help determine time‚ and/or cause of death. 3. What is facial reconstruction

The average life expectancy has increased over the last century; the average life expectancy for women is 80 years while men are expected to live to about 75 years old. The population of older adults over the age of 65 years is expected to increase from 35 million in 2000 to 70 million by the year 2030. Aging is a slow decline in the ability of an organism to resist stress‚ damage‚ and disease. As the human body ages there are physical and biological changes that occur as well. The lifestyles that

Osteoporosis exists; they have no knowledge of what this disease is about or how to prevent it. In the article “c-Maf and you won’t see fat” Laurie McCauley defines Osteoporosis as “a metabolic bone disease that results from an imbalance between the process of bone formation and bone resorption‚ leading to reduce bone mass and increased susceptibility to fracture.” And according to Matthew Taylor‚ in his article “Osteoporosis: An Opportunity to Serve” Osteoporosis was “only officially recognized as a disease
