Muscle tension is affected by different factors; such as the frequency of the stimulation. With a single stimulus, a muscle twitch is formed; muscle twitch consists of three phases: latent, contraction, and relaxation. Wave summation occurs when another stimulus is applied to a muscle before a full relaxation period, after the first stimulus. On the other hand, treppe occurs when another stimulus is applied right after the relaxation period of the first stimulus. With an increase in the frequency of stimulation, incomplete tetanus occurs in which the contraction and relaxation periods become very short. With even faster frequency of stimulation, complete tetanus occurs in which there is no relaxation periods and the contractions blend to form a continuous total contraction wave. Endocrine system consists of many glands that release hormones into the body to help maintain its homeostasis. The major endocrine glands are: pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, the gonads, thymus, and pineal
