Properly functioning muscles perform only one duty, contraction. Muscles enable the body to sit, to move and to stand upright. They are attached by way of tendons to bones.

HOW DO MUSCLES GET THE ENERGY TO WORK?
In muscles, it is essential that Calcium is present, as this gives the muscles the ability to contract and relax. For muscles to contract energy is needed: the energy can only be provided by the breakdown of a chemical called adenosine triphosphate (ATP). As ATP is broken down, a phosphate molecule is broken off, reducing the phosphate molecules, from 3 to 2. This produces adenosine triphosphate. However for the muscles contraction to...

Muscle Contraction - 837 Words
Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine, the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers....

How muscles work and get the energy they need to work.
Muscles need energy to work and move. (1) Their main source of energy is glucose. Glucose is made of a number of different types of carbohydrates (usually sugar) as well as milk and fruits. Glucose turns into other chemicals such as water and carbon dioxide which releases energy. (2)Your muscles get warm when using or burning energy. Glucose is sent to muscles through red blood cells; this is how muscles...

Muscle fatigue is weakness or weariness resulting from exertion or prolonged stress and the failure to maintain an expected power output. (Amussen) The process by which your body produces energy is called glycolysis. During glycolysis, glycogen is broken to produce creatine phosphate, which releases energy. The energy released catalyzes a reaction to produce ATP. The ending product of glycolysis is lactic acid, which is created by breaking pyruvate acid down. Then lactic acid is broken down to...

Viany Reyes November 08, 2011
Neuronal signaling in muscle contraction is triggered when an action potential reaches the neuromuscular junction. At this junction, acetylcholine (ACh) is the main neurotransmitter. Packaged in vesicles, ACh fuses with the neuron’s membrane and is released into the synaptic cleft. ACh diffuses toward the motor end plate and bind to the neurotransmitter receptor on it. The muscle fiber is then triggered to produce an action potential of its...

How to “bulk up” properly for bodybuilding
Have you ever wondered how to gain the muscle without gaining a lot of body fat? Here I will explain to you why bulking is of substantial importance in the sport of bodybuilding. I will inform you on what kind of a diet you should follow, when to bulk, the training that goes along with it, and proper rest to ensure that you get maximum muscle growth. Most bodybuilders bulk up to gain size, muscle and strength. If I wanted to compete even at the...

Muscle Contraction Tutorial/Review
1. Hydrolysis is the decomposition of a substance by the insertion of water molecules between certain of its bonds. The third phosphate is removed by hydrolysis and free energy is released. ADPneedds to have another phosphate molecule in order to become ATP and this happens through hydrolysis. This ATP can be used in the muscle contraction and relaxation.
2. When one flexes his/her arm, the muscle on top is the bicep. The origin of the bicep is at the...

The aim of this experiment is to explore the basic physiological principles of skeletal muscle using the isolated frog (Rana pipiens or Xenopus laevis) gastrocnemius muscle. Students will dissect a double-pithed frog. Then, they will connect the muscle to the Force Transducer to measure twitch recruitment, effect of stretch, muscle summation, muscle tetanus, and muscle fatigue.

Muscle Contraction Steps - 428 Words
During a Muscle Contraction
The muscle fiber is in a resting state. The resting state is slightly negative inside and slightly positive outside. It has to be in this state in order to receive a message. First the brain sends a message to the muscle using a neuron then reaches the axon terminal of the neuron. Calcium gates then open on the axon terminal allowing calcium to rush in. Ach release from axon terminals, diffuses across the synaptic clef and binds to (receptors) on motor end plate....

How to Build Muscle
1. Develop a Technique
Learn the proper way to do each exercise whether it is pushups or weight training. Developing a solid technique will maximize the workout and strengthen the muscles.
Strength training is a method that should not be overlooked because it allows a person to start with minimal weight and add more weight as they progress. This builds more muscle which in turn builds more strength.

11.2.1 State the roles of bones, ligaments, muscles, tendons and nerves in human movement.
Bones: Provide a firm anchorage for muscles. They also act as levers, changing the size or direction of forces generated by muscles.
Ligaments: connect bone to bone, restricting movement at joints and helping to prevent dislocation.
Muscles: The muscles provide the force necessary for movement by shortening the length of their fibres or cells.
Tendons: attach muscle to bone

1. Based on the results of your investigation, what conclusions can you draw about the relationship between a muscle's workload and its threshold of stimulation?
When the workload doubles, the threshold of stimulation will increase by 1. The muscles that have a higher threshold of stimulation can take on a high workload if it originally had no workload.
2. . Why would a muscle's threshold of stimulation change as its Workload changes?
The muscle will need a higher stimulation and work...

Histology is the study of tissues: in our case, it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However, tissue also contains two other components i.e. ground substance (or matrix) and fibres.

Muscles in the Human Body - 879 Words
The musculoskeletal system is made up of bones, joints, and muscles. This system gives the body form and support, and protects the body while allowing it to move. Basically, the muscles in this system perform three important body functions: the movement of body parts, maintenance of body parts, and production of body heat.
These muscles all consist of a mass of protein fibers grouped together, and most are of mesodermal origin. And almost all of the muscle fibers you will ever have or need...
