MUSCLE FATIGUE 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 continue

Muscle tissue Muscle tissue has a ability to relax and contrast and so bring about movement and mechanical work in various parts of the body. There are other movements in the body too which are necessary for the survival of the organism such as the heart beat and the movements of the alimentary canal. Muscles can be divided into three main groups according to their structure * Smooth muscle tissue. * Skeletal muscle tissue. * Cardiac (heart) muscle tissue.

Muscle Contractions By: Evan Contractions‚ put simply‚ are the basic action of any muscle. A contraction is a change in a muscle by which it becomes thickened and shortened after the brain sends signals to nerve cells telling them do contract a specific muscle or muscles. Surprisingly‚ a contraction is a complex human action and reaction‚ yet it is such a breeze to understand the basic meaning of the word. Throughout this essay I will give you extensive details about the process of muscle contractions

Premium Acetylcholine Nervous system Muscle
Q1 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. Through

Any of several small‚ often brightly colored earthly frogs that inhabit the rain forests of Central and South America and secrete from their skin some of the most poisonous biological toxins known‚ such as batrachotoxin. It is on the forest floor that the native South Americans find the jewel-like poison dart frog. The Choco’ tribe in Colombia‚ South America uses the skin secretions to poison their dart tips. One technique used to treat darts requires that a sharp stick to be forced into the
