of the joints in our bodies are surrounded by synovial fluid‚ a thick‚ clear liquid. When you stretch or bend your finger to pop the knuckle‚ you’re causing the bones of the joint to pull apart. As they do‚ the connective tissue capsule that surrounds the joint is stretched. By stretching this capsule‚ you increase its volume. And as we know from chemistry class‚ with an increase in volume comes a decrease in pressure. So as the pressure of the synovial fluid drops‚ gases dissolved in the fluid become

frequency‚ pitch is an auditory sensation of frequency and thus the two are not interchangeable. Research into how the auditory system is able to encode frequency information entering the ear suggests possible mechanisms taking place on the basilar membrane of the inner ear. Interestingly‚ studies also show how the brain is able to perceive a pitch when its corresponding frequency is not present in the sound entering the ear. This phenomenon is called the ‘missing fundamental’‚ as mentioned in the quote

Callum Bourke Describe the long term effects of exercise on the Muskoskeletal system and energy systems. (P3) Describe the long term effects of exercise on the cardiovascular and respiratory systems. (P4) Cardiovascular System Cardiac Hypertrophy The heart increases in size and volume; this allows more blood to enter the heart allowing a greater amount of oxygenated blood to be pumped to the working muscles. To withstand the large amount of blood‚ the left ventricle becomes thicker

CHAPTER 1 Interest in the human body and how it functions probably developed when our ancestors began to think about the reasons why people became ill and died. All earlier cultures had someone designated as a healer who was responsible for finding plants and herbs that cured body disorders. This healer also was responsible for praying or invoking the assistance of past ancestors to help in the healing process. As cultures developed and science began to evolve‚ interest in and knowledge about

MUSCULOSKELETAL ASSIGNMENT 2016 Hinge Joint- Knee The knee joint is the largest joint in the body‚ consisting of 4 bones and an extensive network of ligaments and muscles. What is the scientific name of this joint? The knee joints that make up the knee are split into three parts. The femur meets the tibia to form the main knee joint. This joint has an inner called medial and an outer called lateral compartment. The patella joins the femur to form a third joint‚ called the patellofemoral joint. The

Rheumatoid Arthritis Rheumatoid Arthritis (RA) is a chronic autoimmune disease that causes inflammation of joints leading to hot‚ swollen and painfully restricted movements. RA can also affect other parts of the body such as the eyes or lungs. In the early mornings RA presents as joint stiffness that eases during the day. If left untreated‚ repetitive inflammation often results in joint damage. RA can occur at any age‚ but usually presents in people from 35 to 643. With an estimated half a million

The key bones involved in a rugby tackle vary throughout the whole body. The specific bones used are part of the appendicular skeleton that consist of bones that control the limbs of the body. This boners are specifically located in the uppper-chest/arm area and the leg area. For the upper-chest/arm area‚ the predominant bones involved include‚ the scapula‚ humerus‚ clavicle‚ radius and ulna. As for the leg area‚ the prevalent bones invloved in a rugby tackle include the hip flexor‚ femur and tibia

• Cardiac hypertrophy- This is when the heart increases in size and volume‚ the wall of the left ventricle will get thicker with the help of constant exercise‚ this leads to an increased force of contraction. This will allow the heart to pump out a larger amount of blood with each pump‚ therefore a more efficient heart as it will not have to beat as many times as an untrained heart. • Increase in stroke volume and cardiac output- Stroke volume is defined as the amount of blood the heart is able to
