Tongue: Is a muscular organ in the mouth. The tongue is covered with moist, pink tissue called mucosa and tiny bumps called papillae. Thousands of taste buds cover the surfaces of the papillae. Taste buds are collections of nerve-like cells that connect to nerves going into the brain. There are four types of taste buds: sour, sweet, bitter and salty. The tongue is vital in tasting and chewing food and in speech. Smell: Nose: The nose, along with the mouth, lets air in and out of the body. It also helops us distinguish different smells in that air. The nasal root is the top of the nose, forming an indentation at the suture where the nasal bones meet the frontal bone.
