- babies instinctively do not like bitter or sour flavours (protection) 

- your tongue is very strong and made up of 8 muscles

How do we call the sensory receptors of the tongue?

Why do we taste badly when we have a cold?

1. we do taste but because we feel ill our brain doesn’t register the flavours.
2. because the nasal cavity is full of snots and no chemicals get to the receptors
3. because the nerves are broken
4. the taste buds are covered with mucus
