Osteoporosis is a disease that affect strength of the bones ( literally the word osteoporosis means “ porous bone” ) leading to increased risk of bone fractures. The bone strength has two main properties‚ the mass and the quality of the bone. The bone is a living tissue made up of tough elastic collagen fibers and minerals and contains cells that make and moulds itself in a process called bone resorption‚ it also forms the rigid skeletal framework that protects body organs. Osteoporosis is influenced

primary functions of muscles? What are skeletal muscles made of? Five Skeletal Muscle Functions 1.Produce movement of the skeleton •By pulling on tendons that then move bones 2.Maintain posture and body position 3.Support soft tissues •With the muscles of the abdominal wall and the pelvic floor 4.Guard entrances and exits •In the form of sphincters 5.Maintain body temperature •When contraction occurs‚ energy is used and converted to heat Skeletal muscles are organs Made of: •Connective

What really causes Osteoporosis? The first thing is it is very common in women but not really for men‚ but they too can get Osteoporosis to. Another thing is when women stop menstrulating Bone loss will start to happen then after that there Estrogens leve start to go down really fast. Younger women that went through menopause cause of sports or they are anoxria are more likely to get Osteoporosis‚ the reason is they are slowly losing bone loss. People that had surgery to remove both of their Ovaries

Lab 3 – Skeletal Muscle Physiology Introduction Skeletal muscles are composed of hundreds to thousands of individual cells‚ each doing their share of work in the production of force. As their name suggests‚ skeletal muscles move the skeleton. Skeletal muscles are remarkable machines; while allowing us the manual dexterity to create magnificent works of art‚ they are also capable of generating the brute force needed to lift a 100-lb. sack of concrete. When a skeletal muscle from an experimental

To define these terms used in describing muscle physiology: multiple motor unit summation‚ maximal stimulus‚ treppe‚ wave summation‚ and tetanus. 2. To identify two ways that the mode of stimulation can affect muscle force production. 3. To plot a graph relating stimulus strength and twitch force to illustrate graded muscle response. 4. To explain how slow‚ smooth‚ sustained contraction is possible in a skeletal muscle. 5. To graphically

The muscle physiology of skeletal muscle was observed by using electrical‚ physical‚ and neural stimulations of an isolated gastrocnemius muscle from Rana pipiens. The gastrocnemius receives signals from the action potentials of the sciatic nerve. The muscle contraction is caused by the binding of a neurotransmitter once the action potential reaches the neuromuscular junction. Stimulation of the muscle and the sciatic nerve allows for recording and measuring of these properties. We observed twitch

Summarise the positive and negative effects on the skeletal and muscular systems of a young person performing contact‚ high impact and repetitive sports. There can be both positive and negative outcomes to a young performer. Positive effects can be the strengthening of the body. Negative effects can be that serious injuries can occur to the undeveloped young performer’s body and not be able to do that sport after. The skeletal system and the muscular system are both systems in the body that can benefit

2. FLNB in Skeletal Diseases Mutations in FLNB lead to various skeletal malformations‚ involving long bone‚ joints and vertebra. There were five FLNB-related skeletal disorders been reported so far‚ including spondylocarpotarsal synostosis (SCT)‚ Larsen syndrome‚ atelosteogenesis (AO)‚ boomerang dysplasia‚ and isolated congenital talipes equinovarus. (1) Spondylocarpotarsal synostosis syndrome (SCT‚ OMIM 272460) Spondylocarpotarsal synostosis syndrome was characterized by the following features:

I chose to read the article‚ “Osteoporosis in multiple sclerosis” written by Andrew P Hearn and Eli Silber. It is an understanding about osteoporosis and the connection it might have with multiple sclerosis (MS) compared to patients that do not have multiple sclerosis. Multiple sclerosis is a neurological disability that affects a great amount of young adults. The longer a person has multiple sclerosis‚ the more the person loses strength in there bones. Osteoporosis occurs when the body does not

What is it? (Cause) Osteoporosis - a medical condition in which the bones become brittle and fragile from loss of tissue‚ typically as a result of hormonal changes‚ or deficiency of calcium or vitamin D. Osteoarthritis - degeneration of joint cartilage and the underlying bone‚ most common from middle age onward. It causes pain and stiffness‚ especially in the hip‚ knee‚ and thumb joints. Symptoms of… Osteoporosis • a loss of height as you age caused by compression in the spine or • experiencing
