What division of the autonomic nervous system that prepares the body for intense levels of activity and stressis the?
It's sympathetic division arouses its parsypathic division calms sympathetic division of the autonomic nervous system that arouses the body mobilizing it's energy in stressful situations.
What would not occur if the parasympathetic division was more active than the sympathetic division?
Fight or flight response would not occur.
What secretes norepinephrine adrenergic fibers?
sympathetic division. Parasympathetic division fibers called cholinergic fibers release acetylcholine.
The involuntary muscles are controlled by what?
The involuntary muscles are primarily composed of smooth muscle and specialized striated muscle known as cardiac muscle. All skeletal muscle is under voluntary control. Hence, the involuntary muscles are under control of the autonomic nervous system, which can be further divided into the sympathetic and parasympathetic divisions. The sympathetic division is readying the body into action, hence the "fight or flight" response associated with it, and the parasympathetic division associated with "rest and digest". :)
Which has more specific local control the sympathetic or parasympathetic division of the autonomic nervous system?
The parasympathetic system has more control, as the sympathetic system includes hormonal effectors that work across the entire body.
What nervous system gets your body ready for action in an emergency by increasing adrenalin and slowing down digestion.?
sympathetic division of the autonomic nervous system
From what areas of the CNS does each division originate?
The parasympathetic originates from the brain and spinal cord. The sympathetic originates from the thoracic and lumbar spinal nerves.
Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.
List the division of the autonomic nervous system?
the autonomic nervous system (ANS) includes the peripheal nerves and ganglia on either side of the spinal cord ( note: some textbooks include the ANS as a division pf the peripheal nervous system both ways are correct.)
Which systems act on the same organs but in opposite ways?
The Autonomic Nervous System (ANS) regulates the action of smooth muscles, cardiac muscle, and some glands.In other words, the ANS regulates involuntary (automatic; unconscious) actions.There are two major divisions of the ANS. The parasympathetic division functions under normal conditions (to maintain homeostasis), and the sympathetic division of the ANS functions under stress.Some times the sympathetic divison is called the "Fight or Flight" response and the parasympathetic division is called the "Rest and Repose {turkey dinner syndrome)" response.
Which neuro transmitter released from ganglionic of the parasympathetic division?
Nor-adrenaline is secreted at post ganglionic sympathetic synapses. There is re-uptake of Nor-adrenaline by nerve ending and only partially destroyed there by the enzyme C.O.M.T. There is no enzyme like acetylcholinesterase present there as in post ganglionic parasympathetic synapse to destroy the acetylcholine.
What division of the nervous system Returns the body to normal resting levels after the fight or flight response?
Parasympathetic
