When the face is submerged and water fills the nostrils, sensory receptors sensitive to wetness within the nasal cavity and other areas of the face supplied by the fifth (V) cranial nerve (the trigeminal nerve) relay the information to the brain. The tenth (X) cranial nerve, (the vagus nerve) – part of the autonomic nervous system – then produces bradycardia and other neural pathways elicit peripheral vasoconstriction, restricting blood from limbs and all organs to preserve blood a… Splet11. dec. 2024 · The mammalian dive response (MDR) is a generally unrecognized feature of the human body that is automatically activated when we immerse in water.

In previous studies, such as those performed by Elsner (1971), Gooden (1994) and Leuenberger (2001), it was found that when the diving reflex was induced, peripheral limb blood flow decreased dramatically at the same time that arterial blood pressure rose. This reflects the elicited limb vasoconstriction response.
