The parasympathetic nervous system has been said to promote a "rest and digest" response, promotes calming of the nerves return to regular function, and enhancing digestion. Functions of nerves within the parasympathetic nervous system include:[ citation needed ] Dilating blood vessels leading to the GI tract, increasing the blood flow. Constricting the bronchiolar diameter when the need for oxygen has diminished Dedicated cardiac branches of the vagus and thoracic spinal accessory nerves impart parasympathetic control of the heart myocardium Constriction of the pupil and contraction of the ciliary muscles , facilitating accommodation and allowing for closer vision Stimulating salivary gland secretion, and accelerates peristalsis , mediating digestion of food and, indirectly, the absorption of nutrients Sexual. Nerves of the peripheral nervous system are involved in the erection of genital tissues via the pelvic splanchnic nerves 2—4. They are also responsible for stimulating sexual arousal. Enteric nervous system[ edit ] The enteric nervous system is the intrinsic nervous system of the gastrointestinal system.

There are three phases of the respiratory cycle: The number of cycles per minute is the respiratory rate. The respiratory rate is set in the respiratory center by the dorsal respiratory group, in the medulla, and these neurons are mostly concentrated in the solitary nucleus that extends the length of the medulla.

The basic rhythm of respiration is that of quiet, restful breathing known as eupnea. Quiet breathing only requires the activity of the dorsal group which activates the diaphragm , and the external intercostal muscles. Exhalation is passive and relies on the elastic recoil of the lungs. When the metabolic need for oxygen increases, inspiration becomes more forceful and the neurons in the ventral group are activated to bring about forceful exhalation.

Depression of the respiratory centre can be caused by: A depression can also be caused by drugs including opioids , and sedatives. The respiratory centre can be stimulated by amphetamine , to produce faster and deeper breaths.

It has been described as "the Second Brain of the Human Body". At the effector organs, sympathetic ganglionic neurons release noradrenaline norepinephrine , along with other cotransmitters such as ATP , to act on adrenergic receptors , with the exception of the sweat glands and the adrenal medulla: Acetylcholine is the preganglionic neurotransmitter for both divisions of the ANS, as well as the postganglionic neurotransmitter of parasympathetic neurons.

Nerves that release acetylcholine are said to be cholinergic. In the parasympathetic system, ganglionic neurons use acetylcholine as a neurotransmitter to stimulate muscarinic receptors.

At the adrenal medulla , there is no postsynaptic neuron. Instead the presynaptic neuron releases acetylcholine to act on nicotinic receptors.

Respiratory center - Wikipedia

Stimulation of the adrenal medulla releases adrenaline epinephrine into the bloodstream, which acts on adrenoceptors, thereby indirectly mediating or mimicking sympathetic activity. Caffeine effects[ edit ] Caffeine is a bio-active ingredient found in commonly consumed beverages such as coffee, tea, and sodas. Short-term physiological effects of caffeine include increased blood pressure and sympathetic nerve outflow. Habitual consumption of caffeine may inhibit physiological short-term effects.
