The control of heart rate by the autonomic nervous system was investigated in conscious human subjects by observing the effects of /3-adrenergic blockade with propranolol, of parasympathetic blockade with atropine, and of combined sympathetic and parasympathetic blockade. The increase in heart rate with mild exercise in supine men was mediated predominantly by a decrease in parasympathetic acti...

There is mounting evidence that burnout is a risk factor for cardiovascular disease (CVD). Stress-related dysregulation of the sympathetic and parasympathetic system and the hypothalamic pituitary adrenal (HPA) axis may explain the enhanced risk for CVD. To test this hypothesis, 55 patients (34 males and 21 females) with burnout on sickness absence and 40 healthy participants (16 males and 24 f...

The adult prostate gland grows and develops under hormonal control while its physiological functions are controlled by the autonomic nervous system. The prostate gland receives sympathetic input via the hypogastric nerve and parasympathetic input via the pelvic nerve. In addition, the hypogastric and pelvic nerves also provide sensory inputs to the gland. This review provides a summary of the i...

One of the primary functions performed by the cardiovascular system is the delivery of oxygen and metabolic substrates to the peripheral tissues during varying levels of their activity. Accordingly, the manner in which the circulation is altered during muscular activity and the consideration that the cardiovascular response is mediated through the interaction of a number of mechanisms, prominen...

Meditation is a common practice in certain religions. Non religion meditation practice is now more and more popular. Meditation can provide a stress relief method via relaxation reaction. It can enhance parasympathetic tone and suppress sympathetic tone. Sympathetic nerve system is a fear-and-fight stress machinery accompanying steroid secretion. Majority of anxiety and depression patients are ...

OBJECTIVE Dysregulation of the autonomic nervous system is thought to be involved in craniopharyngioma-related hypothalamic obesity (CRHO). Increased parasympathetic activity and decreased sympathetic activity have been suggested. We aimed to study autonomic activity using heart rate variability (HRV) and biochemical measures in youth with CRHO compared with controls and to explore relationship...
