"In the context of abortion, fetal analgesia would be used solely for beneficence toward the fetus, assuming fetal pain exists.
Taste buds are clusters of taste receptor cells, which are also known as gustatory cells. [1] The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue , soft palate , upper esophagus , the cheek , and epiglottis .
At the beginning of the ninth week, the embryo is termed a fetus (spelled "foetus" in British English). In comparison to the embryo, the fetus has more recognizable external features and a more complete set of developing organs.

The tongue's taste buds, located in the enlarged papillae, facilitate food handling after birth. These taste buds develop during fetal development. Adult pigs have up to 15,000 taste buds, a much larger number than the average human tongue, which has 9,000. [19] The dental anatomy of the fetal pig shows differences from adult pigs.
Lingual taste bud organoids containing taste cells, however, ... the organoids persist and have some features of human fetal development stages. ...
The diagram above depicts the signal transduction pathway of the sweet taste. Object A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane. II.
