Connective Tissue Lactic Acid
1,736 wordsThe immediate source of energy for muscular contraction is the high-energy phosphate compound called adenosine triphosphate (ATP). Although ATP is not the only energy-carrying molecule in the cell, it is the most important one, and without sufficient amounts of ATP most cells die quickly. The three main parts of an ATP molecule are: an adenine portion, a ribose portion, and three phosphates linked together. The formation of ATP occurs by combining adenosine diphosphate (ADP) and inorganic phosph...

Plays A Major Role Parkinsons Disease
382 wordsAn integral component Dopamine Dopamine An integral component of the Central Nervous System is dopamine. Dopamine is a neurotransmitter which plays a major role in carrying out two activities of the CNS. Dopamine assists in controlling movement, and it is strongly linked with behaviors based on emotion. Neurons from an area of the brain, substantia nigra, which connects to the corpora strata is the area from where dopamine is released. This pathway is involved in movement control and the musculo...

Coronary Artery Disease Beats Per Minute
2,046 wordsThe Normal Cardiac Cycle During each heartbeat, the two upper chambers (right and left atria) contract, followed by contraction of the two lower pumping chambers (right and left ventricles). This action is coordinated by the hearts electrical system. Normal electrical activation of the heart occurs in an orderly fashion. With each beat, the electrical impulse starts in the sinus (or sino atrial) node (in the right atrium). The impulse spreads through the atria, stimulating the atria to contract....
