The person may be asked to swallow, and a tongue blade may be used to elicit the gag response. Changes in autonomic variables following two meditative states described in yoga texts. This nerve is mainly responsible for the ability to swallow, the gag reflex, some taste, and part of speech. Telles S, Raghavendra BR, Naveen KV, Manjunath NK, Kumar S, Subramanya P. Breath of life: the respiratory vagal stimulation model of contemplative activity. It is responsible for feeling in the tongue and throat and movements such as swallowing and the gag.

Thus, sensory examination of the outer ear and angle of the mandible should be normal in isolated peripheral trigeminal nerve injury. doi:10.3340/jkns.2019.0037Įpilepsy Foundation. The glossopharyngeal nerve is the 9th cranial nerve. The coverage of the outer ear is complex: it involves the great auricular nerve (supplied by C2, C3) and cranial nerves 7, 9, and 10 the angle of the mandible is covered by the great auricular nerve.

Loss of appetite, feeling full quickly or unexplained weight loss. Difficulty swallowing or loss of gag reflex. The vagus is known as cranial nerve X, the Roman numeral for 10.

Cold-water immersion: Facial immersion in cold water is thought to indirectly stimulate the vagus nerve. The vagus nerves are the 10th of 12 cranial nerves.

This may be especially true with low-frequency sounds delivered with slow, rhythmically structured music. Stroking each side of the mucous membrane of the uvula.

Music therapy: It is thought certain types of music can positively influence moods and elicit a beneficial autonomic response. Touching each side of the pharynx with the sterile tongue depressor tests the pharyngeal gag reflex.

Foot reflexology: This massage-based practice has been shown to slow heart rate and respiration, lower blood pressure, and increase oxygen saturation, suggesting that it positively stimulates the vagus nerve.

However, in this case, the sensory limb of the reflex is the trigeminal nerve. Some studies suggest such practices can improve vagal nerve tone, leading to a slower heart rate and lower blood pressure. As with all reflexes, the gag reflex has a sensory and a motor limb.

Mindfulness exercises: These include practices like yoga and tai chi in which respiration is synchronized with body movements.

Deep breathing exercises: Slow, conscious breathing is thought to stimulate the vagus nerve, not only improving heart rate and blood pressure but also easing digestion.
