Double muscled cattle are the result of a genetic defect causing hypertrophy of the skeletal muscles. Symptoms/Etiology: Double muscling is the result of a defect in the myostatin gene, which is responsible for regulating the growth of muscle fibers during development. Without a functioning mysostatin gene, muscles will develop hypertrophy (increase in muscle fiber size) and hyperplasia (increase in number of muscle fibers), resulting in the appearance of a âdouble muscledâ animal.
Excessive sweating around the male genitals can cause much discomfort and embarrassment especially if there is a bad body odor that accompanies it. It can further lead to rashes, itching and peeling of the skin in the area around the groin.weet. Sweat secretion is controlled by the sympathetic nervous system. Excessive sweating or hyperhidrosis is caused by a number of reasons including hormonal changes, endocrine imbalances, chronic medical conditions, psychiatric disorders, obesity as well as certain medications.
Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. The eccrine sweat glands are distributed over much of the body. In humans, sweating is primarily a means of thermoregulation which is achieved by the water-rich secretion of the eccrine glands.Maximum sweat rates of an adult can be up to 2â4 liters per hour or 10â14 liters per day (10â15 g/minâ¢mÂ²), but is less in children prior to puberty.Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling.he most commonly experienced symptom of excessive sweating is body odor. Odor develops due to yeast or bacteria that live naturally on the skin. As the skin becomes moist and mixes with these, odor is released. Another explanation is when the apocrine gland release sweat directly into the tubule of the glands.
