ADHD is low muscle tone which is due to abnormal chemical balances in the brain; “ADHD is caused by differences in neurotransmitter patterns in certain parts of the brain. Neurotransmitters are chemicals that make it possible for nerve impulses to travel from one nerve cell to another‚ and therefore play an essential role in the functioning of the brain. The brain performs a vast range of tasks or functions‚ allowing us‚ for instance‚ to see‚ hear‚ think‚ speak and move. Each function is

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.

Neurogenic Shock Neurogenic shock is a type of shock that is caused by a spinal cord injury that affects important nerves in the nervous system. Injury to the nervous system causes the walls of blood vessels to relax‚ which increases the blood pressure. Neurogenic shock mainly affects the spinal cord. The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. Neurogenic shock occurs when a spinal cord injury happens‚ particularly involving

compounds prevent blood clotting. *Thromboses - Coagulate blood and foster clot formation throughout the circulatory system. *Haemolysis - Destroy red blood cells. *Cytolysins - Destroy white blood cells. *Neurotoxins - Block the transmission of nerve impulses to muscles‚ especially those associated with the diaphragm and breathing.

parasympathetic nerves‚ which have only a modulatory function on the contractile activity. Sympathetic innervation originates from postganglionic fibers of the hypogastric plexus and it has an inhibitory effect on the motor function‚ making connections with neurons of the enteric nervous system‚ which in turn sends fibers to smooth muscle cells‚ inhibiting the contraction. On the other hand‚ parasympathetic fibers‚ which originate from the sacral plexus (S2–S4) and run into the pudendal nerve‚ send preganglionic

fasten the buttons because as you get older your receptors become less sensitive this is linked to the fact that the brain and nervous system goes through natural changes‚ your brain and spinal cord lose nerve cells and weight therefore nerve cells begin to pass messages more slowly‚ a breakdown of nerves can affect your senses. You might have reduced or lost reflexes or sensation. This leads to problems with movement and safety. This can affect people’s self-confidence as they may not understand their

conclusion is that there is an effect outside of the heating effect. The effects of the changes produced by high intensity sound upon the central nervous system has been investigated. The results show that nerve cells are particularly sensitive to ultrasonics‚ while blood vessels and nerve fibers are much more resistant. A study of the therapeutic effect of ultrasonics shows that the heat which is produced plays the major role. However‚ ultrasonics also produces a mechanical effect. Ultrasonics
