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

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.

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

Animals have three types of muscles; skeletal‚ smooth‚ and cardiac. This lab however is only concerned with skeletal muscle. A special characteristic of skeletal muscle is their ability to contract or shorten via thin (actin) and thick (myosin) filaments (Flanagan‚2017). This gives a striated appearance which is a key distinguishing characteristic between other types of muscle (Flanagan‚2017). Skeletal muscle is also multinucleated. Skeletal muscle needs plentiful amounts of energy to be able to

"seeing-doing" because your muscles seem to "know" and "remember" just what to do. What you’re learning now is speed‚ i.e. how to perform the task carefully and quickly. That’s muscle memory. Scientists call this "kinesthetic memory" or "neuro-muscular facilitation" and they speak of "sensory-motor" learning‚ since you are combining sensing input‚ i.e. what you see with your eyes‚ with motor output‚ i.e. what you do with your body. Of course‚ during the "drill-and-practice"‚ your muscles aren’t really memorizing
