Visceromotor reflex

Reflexes Visceral Motor-Viscero-Resulting are peripheral motor reflexes aimed at regulating homeostasis, i.e. maintaining the constancy of the internal environment of the body. They arise from irritation in any area of ​​the body, and are realized through internal organs. Supragastrically, this occurs with the participation of the salivary glands, skin, myocardium and peritoneum; in the abdominal cavity - the gall bladder, liver, pancreas, stomach and intestines; liver, gall bladder system and pancreatism, urinary tract, prostate and uterus in women. Based on the duration of responses, two types of peripheral reflexes are distinguished:

Reflexes are reactions of the body that occur when exposed to external or internal stimuli. Reflexes help the body maintain balance and maintain normal functions. One of these reflexes is the Visceral reflex.

The visceral or viscireomotor reflex is the body’s response to mechanical irritations of the skin of the chest and abdomen from the inside. It also stimulates certain muscles. This protective reflex response causes tension in the abdominal muscles, diaphragm, and other muscles that help protect internal organs from damage.

An example of a protective reflex action can be local mechanical effects on the anterior abdominal wall. For example, piercing the skin with needles on the skin of the abdomen or hitting the skin of the abdomen with tweezers.

Due to the protective reflex action from mechanical irritation, segmental and parasympathetic spinal centers are mobilized on the anterior abdominal wall. They excite the elements of the conduction pathway and the peripheral endings of the afferent nerves of the lower part of the chest and abdominal walls. Having passed this path, excitation is transmitted to the lumbar and sacral parts of the spinal cord.

Next, the impulse is transmitted to the diencephalon, where the vagal projection of the center of the sympathetic part of the reticular
