Reflex Skin-Mucous

The mucocutaneous reflex (r. cutaneomucosus, Kussmaul-Melzack reflex) is a protective reflex that occurs when a foreign body comes into contact with the mucous membrane of the mouth or throat. In this case, the muscles of the pharynx and larynx contract, which leads to the closure of the airways and prevents the foreign body from entering the lungs.

The mucocutaneous reflex is congenital and develops in the womb. It is activated by irritation of the mucous membrane of the mouth and throat, such as food or liquid, or by contact with the skin around the mouth and nose, which may be due to damage or irritation of the mucous membrane.

When the mucocutaneous reflex is activated, the muscles of the throat and pharynx contract, which leads to a narrowing of the airways. This helps prevent foreign bodies from entering the airways and protects the lungs from damage.

It is important to note that the mucocutaneous reflex can be impaired by various diseases or injuries, such as facial palsy, damage to the nervous system, and certain medications. In these cases, there may be a danger to life due to the inability to close the airways when a foreign body enters the mucous membrane.

In general, the mucocutaneous reflex plays an important role in protecting the respiratory tract and is an important mechanism for maintaining human health and life.
