i would also like to kno the answer Yes, even if you feel your neck you can know that. If you feel your neck, you can feel your larynx and trachea. If you feel the back of your neck, you can feel vertebrae. Hope this answered your question!
The chewed up lump of food is known as a bolus.
Oesophagus, portion of the digestive tube that conducts food from the mouth to the stomach. When food is swallowed it passes from the pharynx into the esophagus, initiating rhythmic contractions (peristalsis) of the esophageal wall, which propel the food along toward the stomach. Pharynx, area of the gastrointestinal and respiratory tracts which lies between the mouth and the oesophagus.
Nausea and tightness in the esophagus could be acid reflux, I would recommend you a doctor. It could also mean that you have asthma, I don't know but my throat burns sometimes and i had lower grade asthma, get your GP to give you a lung test it doesn't take very long.
Yes
The wave-like motion of the esophagus is called peristalsis. It helps move food and liquids down the esophagus and into the stomach for digestion.
Just a fatty tumer that's OK if you feel more and more go to a doctor.
