In the bottle neck
Your stomach lining has tiny glands shaped like little bottles. The narrow part at the top is called the neck. Mucous neck cells are squeezed in there.
They are smaller and more squished than the slime cells on the stomach surface. Their mucus bubbles sit near the top of the cell, and their nucleus is pushed to the bottom.
Mucous neck cells live right next to the stem cells that make new stomach lining cells. Scientists think some of them grow up to become chief cells!
