Thyroid 101. Located above the Adam's apple, your thyroid produces thyroid hormone (TH), which regulates, among other things, your body's temperature, metabolism, and heartbeat.

Head lice and their nits are found almost exclusively on the scalp, particularly behind the ears, on top of the head, and near the neckline. They sometimes appear on eyelashes and brows, but this is rare. Head lice grasp the hair shaft with hooklike claws. They don't like light, and they're fast, so you may see or feel the nits only when you closely examine your child's hair. Grab a flashlight, and look or feel for the tiny bumps, which will be cemented firmly to the hair shaft about a quarter-inch from the scalp.
