Your tongue is a mass of muscles. The specific arrangement of muscle fibres allows it to move freely in any direction inside the mouth to performs several different tasks, including eating, swallowing, speaking, licking, sucking, and helping to pronounce words when we speak.
Your tongue contains thousands of taste buds. Taste buds are small organs, embedded in the tongue that enable us to experience taste.
The tip or apex of the tongue accounts for the front one-third of the tongue. It is very mobile and rests against the incisor teeth in the mouth. The taste buds for “sweet” are on this part of the tongue.
The back two-thirds of the tongue form its body. The surface is slightly rough. This is this part of the tongue where the tongue tastes salty, bitter and sour flavours.
