These procedures often include extraction of teeth, root canal, gum surgery, and biopsies. This is why, when the eyes are closed, the upright posture is less steady and there occurs more swaying (bending) of the trunk. This is made possible by the opening of several pulmonary capillaries which are closed at rest. Proteolysis during starvation, which results primarily from decreased insulin and increased cortisol release, is associated with elevated urinary nitrogen excretion from the normal 7 to 10 g per day up to 30 g or more per day. As described above, there is spatial organization of the auditory pathways all the way from the hair cells to the auditory cortex. Therefore, it is important to disarm the patient to obtain reliable information, and transparency on the part of the dental practitioner is required.

The receptor activated will determine the physiologic effect, which may include analgesia, sedation, euphoria, dysphoria, and respiratory depression. Via these pathways, the sensitivity of the muscle spindles and hence the threshold of the stretch reflexes in various parts of the body can be adjusted and shifted to meet the needs of postural control.
