Swallowing, or deglutition, is the process by which food passes from the mouth, through the pharynx and into the esophagus. As simple as it might seem to healthy people, swallowing is actually a very complex action that requires an extremely precise coordination with breathing since both of these processes share the same entrance the pharynx. Failure to coordinate would result in choking or pulmonary aspiration. Swallowing involves over twenty muscles of the mouth, throat and esophagus which are controlled by several cortical areas and by the swallowing centers in the brainstem. The brain communicates with the muscles through several cranial nerves.
Swallowing consists of three phases:

1. Oral or buccal phase: this is the voluntary part of swallowing, the food is moistened with saliva and chewed, food bolus is formed and the tongue pushes it to the back of the throat (the pharynx). This process is under neural control of several areas of cerebral cortex including the motor cortex.
2. Pharyngeal phase starts with stimulation of tactile receptors in the oropharynx by the food bolus. The swallow reflex is initiated and is under involuntary neuromuscular control. The following actions are taken to ensure the passage of food or drink into the esophagus:
The tongue blocks the oral cavity to prevent going back to the mouth.
The soft palate blocks entry to the nasal cavity.
The vocal folds close to protect the airway to the lungs. The larynx is pulled up with the epiglottis flipping over covering the entry to the trachea. This is the most important step since entry of food or drink into the lungs may potentially be life threatening.
The upper esophageal sphincter opens to allow passage to the esophagus.
3. Esophageal phase: food bolus is propelled down the esophagus by peristalsis a wave of muscular contraction that pushes the bolus ahead of it. The larynx moves down back to original position.

This video is an answer to a question I received about the swallowing reflex. With some neurological conditions, the swallowing trigger is diminished and the brain needs some help to initiate the swallow. Here, I give several suggestions to improve the swallow reflex.


How to Improve the Swallow Reflex

Gastrointestinal | Deglutition (Swallowing)

Ninja Nerds,

Join us in this lecture where we will be discussing the physiology of deglutition, simply known as swallowing. The three phases of deglutition will include the oral phase, the pharyngeal phase, and the esophageal phase. We start this video by first talking about the muscles of mastication and how this is important in the formation of a bolus during the oral phase. We then follow that bolus all the way into the esophageal phase where it will eventually be turned into chyme.

What is Sneezing Reflex and Swallowing Reflex? Respiratory Physiology | General Medicine

For More Details Visit http://cepekmedia.co.nf

Sneezing is also a modified respiratory process by forced expiration. It is a protective reflex caused by irritation of the nasal mucous membrane. Efferent nerve fibers from the medullary center pass via trigeminal, facial, glossopharyngeal, vagus and intercostal nerves. These nerve fibers activate the pharyngeal, tracheal and respiratory muscles.

Swallowing reflex is a respiratory protective reflex that prevents the entrance of food particles into the air passage during swallowing. While swallowing the food, the respiration is arrested a while. The temporary arrest of respiration is called apnea. The arrest of breathing during swallowing is called swallowing apnea or deglutition apnea.

Irritation of the nasal mucous membrane occurs because of dust particles, debris, mechanical obstruction of the airway and excess fluid accumulation in the nasal passages.

Sneezing starts with deep inspiration, followed by forceful expiratory with opened glottis resulting in the expulsion of irritant agents out of the respiratory tract.

Sneezing is initiated by the irritation of nasal mucous membrane, the olfactory receptors and trigeminal nerve endings present in the nasal mucosa. Afferent nerve fibers pass through the trigeminal and olfactory nerves. The sneezing center is in the medulla oblongata. It is located diffusely in the spinal nucleus of the trigeminal nerve, nucleus solitaries and the reticular formation of the medulla. It takes place during the pharyngeal stage and prevents the entry of food particles into the respiratory tract.

Sadly, there are a number of additional steps that occur that are not shown in this video, does not show the link between additional following mouthfuls triggering movement further down the throat. This would be more helpful for those dealing with swallowing difficulties if it did.

Is this deglutition marvel beyond computational analysis? That is, the involvement of all these muscles, especially during the critical phase of deglutition, the closure of the larynx by the epiglotis, whose actions are mostly involuntary, be one day elucidated? Could neuroscientist draw a detailed neuronal pathway for the involved cranial nerves impulses, and from the regions of the cortex, as well? I’m just intrigued, astounded, as to how natural selection used the vehicle of waves to accomplish many, if not all, of its functions: this deglutition wave, the peristaltic waves in the esophagus and colons, the wave of the heart function during systole, etc, etc, etc.

Jenny Hughes 21/08/2021 - 06:10

After my throat was severely injured by anaesthetists I asked my GP where my oesophagus was – he just pointed in the general direction of my upper chest & then swiftly moved onto another subject. The medics & hospital lied & covered up my injuries so my throat was left very painful & infected for a year & my neck was injured & a new lump in front of my throat & big squeaks when I swallowed liquids & clicks from inside my throat. 

After 15 years I'm left with difficulty swallowing: things get stuck as they go down (small tablets, nuts, buts of apple etc.) and sometimes they go down the wrong way and I choke & have to cough to try to get them out. Sometimes when I turn my head the bit of bone or cartilage?) they broke in the front of my throat near my voicebox clicks & moves and the whole front & right side of my throat really aches sometimes. 

For a long time I had tiny red dots down the front right side of my neck but my GP took no notice of any of this and refused to help me get info from the NHS hospital here in the UK. The anaesthetists got away with doing all this to me (and giving me brain damage & damaging my eyes/vision & wrecking my digestion and causing right inner thigh muscle to flop out and a weird 'hole' in my thigh muscle) but i'm left to live with all this 24/7.

I've been left for 15 years to try to guess what they did to me & the damage they did to my body – they should have been honest & open and told me the truth right at the start. That's why I'm here: to try to learn again: due to my brain injury I keep forgetting) how swallowing works – IF this is true?!
