Sweat gland

overactive muscles and can also block sweat glands as well as blocking the release of certain chemicals in the brain which are known to cause migraine headaches. In the first case, for example, a Botox injection to treat frown lines works by basically not allowing the facial muscles to contract giving a more youthful appearance due to the absence of lines on the skin. Using Botox to treat sweat glands works by blocking signals in the body which cause a person to sweat excessively, which is…

blood vessels in the skin dilate to radiate heat and the sweat glands increase sweat production. 10b.The two mechanisms the body uses to heat itself are the blood vessels in the skin constrict, reducing heat loss and the muscles begin to shiver, generating heat. 11a. The stimulus is the hypothalamus senses that temperature is too high. The response would be the blood vessels in the skin dilate to radiate heat and the sweat glands increase sweat production. 11b. The feedback loop is negative…

tract (nose to lungs) and the gastrointestinal (digestive) systems are the most affected. Symptoms usually start in the gastrointestinal system. Male fertility and sweat glands are also affected. Only about fifteen percent of babies who carry the disease have meconium ileus which is sticky and thick caused by thick mucus from intestinal glands. Vomiting and abdominal swelling are caused and surgery right after birth is needed usually. If the pancreas does not give digestive enzymes to the…

contains dermal papillae, which are projections that interlock with epidermal ridges. The layers of the dermis include the papillary dermis which is the upper most layer and contains the dermal papillae, and the reticular layer which has the sweat glands, oil glands, and hair follicles. This layer is in contact with the subcutaneous…

protein regulates the transport of Cl- and Na+ c) Explain why a defective CFTR gene could cause Dan to produce very salty sweat. (5 marks) The normal function of the CFTR gene provides instructions for making a protein channel called the cystic fibrosis transmembrane. This protein channel transports chloride ions across the semipermeable membrane of cells that produce mucus, tears, sweat, saliva, and digestive enzymes. Due to osmosis, water will pass through the membrane from low concentrations…

to shiver. The skin arterioles constrict, and the shunt vessels dilate. Less blood flows through blood capillaries in the skin. This reduces the heat lost by convection, conduction, and radiation. Sweat glands become less active, resulting in the decreased production of sweat. As less water in the sweat evaporates from the surface of your skin, less latent heat of vaporization is lost from the body. The metabolic rate increases to increase the amount of heat released within the body. This…

portion of the brain that monitors and regulates the body's temperature. 10a)The body will expand blood flow in the skin and have the sweat glands produce more sweat. 10b)The body will restrict blood flow in the skin and have muscles shiver to generate and keep heat. 11a)The stimulus is the hypothalamus sensing to little heat in the body and the response is the sweat production and blood flow increasing. 11b)Negative because it is decreasing the heat to the original temperature. 12a) The…

how we interact with others and the relationships we form with others. Skin has been utterly basic to survival keeping us waterproof and protecting what is on the inside from the outside. It is a network of fibers keeping us together. We have sweat glands to keep us cool and even nerves to give us feeling. Although essential on a biological level,…

The hypothalamus, is found in the brain, all humans and most animals have it. The hypothalamus is important because it helps the body maintain homeostasis and it controls specific hormones. The word homeostasis is separated into two parts, homeo means “the same” and stasis means “not moving” or to “hold,” (An Overview). In terms of body temperature, homeostasis is referring to the maintenance of internal balance. In order to achieve homeostasis for animals, they maintain a relatively constant…

your brain since your brain makes the choices for your body. This is very important because if you're too cold you can start shivering for long periods of time which can lead up to hypothermia. On the other hand, if you are too hot you and start to sweat a lot it can lead up to avoid disease. Here are the 3 different that your body can make in these tough situations. The first thing your body can do is to move the tiny muscles located all over your skin if you are cold since these muscles can…
