good and common example of a soft tissue injury would be pulling or tearing your hamstring. The hamstring is located at the bag of your leg and runs from the back of your knee to just below the gluteus Maximus. This injury will occur when the muscle is overstretched and is common in most sports but especially football and sprinting due to the amount of work your legs go through. Soft tissue includes tendons‚ ligaments‚ fascia‚ skin‚ fibrous tissues‚ fat‚ and synovial membranes‚ which are connective

INTRODUCTION I am going to explain the voluntary muscle the different types of muscle fibre including slow twitch fast twitch‚including how their properties are influenced by their reliance on aerobic and anaerobic energy sources. Skeletal muscle is made up of bundles of individual muscle fibres called myocytes. Each myocyte contains many myofibrils‚ which are strands of proteins (actin and myosin) that can grab on to each other and pull. This shortens the muscle and causes muscle contraction

The objective of the experiment was to differentiate mammalian C2C12 cells into muscle cells and analyze for presence of myosin light chain. Utilizing Western Blotting techniques and using specific antibodies helped to detect myosin light chain. The hypothesis was that proliferating myoblasts could be induced to initiate the differentiation process by depriving the cells of the necessary growth factors and that the differentiation is characterized by the expression of muscle-specific proteins. The

1.) What muscle did the winging of the scapula suggest to be paralysed? Why does this sign occur? The muscle that was suggested to be paralysed due to the winging of the scapula is the Serratus Anterior muscle. The Serratus Anterior muscle’s origin is situated on the external surface of the lateral surfaces of the upper 8 to 9 ribs (ribs 1 to 8) while the insertion of this muscle is located on the costal surface of the medial border of the scapula. Therefore‚ this muscle is innervated by the long

The body is capable of many movements which collectively‚ allow us to perform everything that involves any movement at all. The six primary movements of the body that occur at the joints between segments are: flexion‚ extension‚ abduction‚ adduction‚ circumduction‚ and rotation. The six primary movements‚ along with any other anatomical movement‚ occur within three planes of motion; frontal‚ sagittal‚ and transverse. Flexion is defined as decreasing the angle between two body segments or bones

Analysis section Strength one –Fitness component: strength Within my chosen activity of football I believe that strength is one of my biggest strengths. Strength is defined as applying force against resistance. As a right full back I have to have strength to hold players off the ball and have to use my strength to push the wingers of the ball .My role in the defence is to stop the attackers and release the ball to the attackers to start a counter attack or pass the ball to build up the attack I

INVESTIGATION OF PHYSIOLOGICAL & MECHANICAL PROPERTIES OF SKELETAL MUSCLE USING FROG GASTROCNEMIUS AIM The purpose of this experiment was to demonstrate the physiological as well as mechanical properties of skeletal muscle using the gastrocnemius muscle of a frog by exploring five different investigations namely the single twitch‚ the graded response‚ the relationship between muscle length and tension‚ muscle tetanus‚ and muscle fatigue. These individual experiments aim to explore the way muscles

Effects of exercises on gullain barre sydrome On skeletal muscles Doing exercises we can increase the muscle strength through strengthening and mobilization exercises. Customize exercises will help to strengthen weak muscles and watch for muscle substitution. For example‚ a patient may show hip hiking and a circumduction gait pattern as a result of substitution hip flexors .Some exercises are helping to improve balance and mobility through valuation of different mobility aids‚ Addition to that postural
