Hand cramping can occur for many reasons and cause significant discomfort in some people. Often, hand cramps are caused by muscle spasms, which are described as an uncontrollable or involuntary muscle contraction. These spasms or contractions do not allow the muscle to become relaxed and can become excruciating in some cases.
Serum levels of prolactin may increase as a consequence of epileptic seizures. The hormone release is caused by the propagation of epileptic activity, usually from the temporal lobe to the hypothalamic-pituitary axis.
Studies have shown a direct effect of prolactin on isolated mammary cell nuclei and presented evidence that prolactin can indeed enter the milk secretory cell, that it does so physiologically, and that it can reach the cell nucleus. Prolactin is also called as a hormone central to an enormous number of diverse life processes in an enormous number of diverse vertebrate formsâextending on the evolutionary scale from cyclostomes to humans.
