Question: How long should my pupils stay dilated after an eye exam? Answer: After a dilated eye exam, your pupils will normally remain dilated for about three to four hours. This time varies according to the type of drop the doctor uses and the color of your eyes. Children are often dilated with stronger drops in order to improve the accuracy of the examination.
What is the main function of muscle tissue? Quick Answer. Muscles have several main functions, including locomotion, heat production, structural support and muscle contractions. Muscles are dense and account for nearly 40 percent of the body's weight.
Muscle tissue functions mainly as a source of power and motion in the body. Muscles' main responsibility is for changing or maintaining posture, locomotion, and movement of internal organs. The human body has about 650 muscles, which make up approximately half our bodyweight. All muscles are basically made of the same material, a kind of elastic tissue; packages of stretchable fiber-like material, similar to what goes into making a rubber band. Each muscle is made of thousands, and sometimes tens of thousands of small musculus fibers. Each muscle fiber is about 40 mm in length and is made up of tiny strands of fibrils. Each muscle fiber is commanded by a nerve which makes it contract. How strong a muscle is depends mainly on how many fibers are present.
