There are many different muscles groups that are used during exercise. Some of the main muscle groups are hamstrings‚ quads‚ glutes‚ and pectoral muscles. There are different muscle within each muscle group. In the hamstring muscles‚ there are three main muscles: semitendinosus‚ semimembranosus‚ and biceps femoris. In the quad muscles there are four main muscles: rectus femoris‚ vastus lateralis‚ vastus intermedius‚ and vastus medialis. There are three main muscles in the glutes: gluteus maximus

Any athlete has surely experienced a muscle cramp before and can tell you the indescribable pain they emit. The main question is what is a muscle cramp and how is it caused. Someone who frequently undergoes muscle cramps may also wonder ‘how do I prevent these?’ Muscle cramps can be a nuisance and may stope athletes or everyday people from doing what they like. When a muscle or group of muscles involuntarily contracts this is called a muscle cramp. A muscle contracting causes it to get smaller

They are your Quadriceps they are the biggest muscles by far they are at the front of the thighs. They raise the thigh and leg. Then there are the Hamstrings these form the back of the thighs and move the leg backward. The Buttocks powerful and bulky complete the backward movement of the step. Stomach muscles

Chapter 10 Muscle The muscular system helps in providing the movement for bones and in doing so allows the body to make complex movements. Muscle is one of the four types of primary tissue. The three kind of muscle tissue that make up the human body are: skeletal muscle‚ smooth muscle‚ and cardiac muscle. Skeletal muscle is voluntary and are usually found attached to bones where they help to produce movement of the skeleton. Smooth muscle is involuntary and are usually found in the walls of the

between the application of the stimulus and the last point where the active force is zero (just prior to contraction). How long is the latent period? _2.78_ msec What occurs in the muscle during this apparent lack of activity? The muscle is reacting internally and getting the signals to contract.

of the bullfrog that was removed at the hip joint through careful dissection of the muscle away from the tibo-fibula bone while leaving the it attached to the knee and heel. The muscle was consistently moistened by Ringer’s solution throughout the entire experiment. The Achilles tendon was removed at the heel of the frog. The tibiofibular bone was cut below the knee and the femur below the knee (Frog Skeletal Muscle Experiement). The baseline value of the force transducer was set to zero. This zeroing

HOW MUSCLES GET THE ENERGY THEY NEED TO WORK 1) Muscle needs energy to contract and as stated previously the ‘universal energy currency’ of living systems is ATP (adenosine triphosphate). This is largely produced within mitochondria‚ organelles which are often referred to as the ‘powerhouse’ of the cell. The ATP that results is used to provide the power for the muscle fibres to contract. Contraction itself (i.e. actual shortening movement) occurs when a bond is broken between ATP and one of its

Muscle Contraction & Excitation Muscle excitation takes place when there is a synaptic transmission and induction of an impulse. There are six steps that take place during muscle excitation. (1)The action potential travels down the somatic motor neuron axon reaching the synaptic bulb causing calcium ions to flow into the synaptic bulb. (2)The increase of calcium in the synaptic bulb causes the synaptic vesicles to undergo exocytosis. (Exocytosis a process that allows large molecule to leave

The goal of PCI (percutaneous Transluminal intervention) is to open the blockage in the coronary artery. By opening the area that is blocked‚ it will help to reperfuse the myocardium. The faster this is done will help

What makes Australia unique? Australia is a very unique and diverse continent that is an island and consists of one nation. Its physical features and cultural environment make it different to other places. Australia is a multicultural country meaning that it respects all cultures‚ religions‚ ethnicities and races. Such features give Australia a special‚ recognised identity. Because of Australia’s long geographic isolation it has resulted in an exceptional variety of plant and animal life. Most of
