Which of the following tissues or cells are not found in a food pipe?

The food pipe, also known as the oesophagus, is a muscular tube (smooth muscle tissue) that connects the pharynx to the stomach, transporting food and liquids from the mouth to the stomach for digestion. The oesophagus is primarily made up of smooth muscle tissue that contracts and relaxes in order to move food down the tube and into the stomach.

The oesophagus is also lined with an epithelial mucous membrane that protects the oesophagus from damage caused by stomach acid and other digestive secretions. 

The oesophagus's outer layer is made up of connective tissue, which supports and protects the muscular and epithelial layers.

Nervous tissue also plays a role in oesophageal function because it controls the muscular contractions that move food down the tube.

Osteocytes are cells that are in charge of bone tissue formation and maintenance.
