In sympathetic and para symptetic nervous system where are the nerves and what and where are the receptors.?
Sympathetic nerves originate inside the vertebral column, toward the middle of the spinal cord in the intermediolateral cell column (or lateral horn), beginning at the first thoracic segment of the spinal cord and are thought to extend to the second or third lumbar segments. Because its cells begin in the thoracic and lumbar regions of the spinal cord, the SNS is said to have a thoracolumbar outflow. Axons of these nerves leave the spinal cord through the anterior rootlet/root. They pass near the spinal (sensory) ganglion, where they enter the anterior rami of the spinal nerves. At the synapses within the ganglia, preganglionic neurons release acetylcholine, a neurotransmitter that activates nicotinic acetylcholine receptors on postganglionic neurons. In response to this stimulus postganglionic neurons - with two important exceptions - release norepinephrine, which activates adrenergic receptors on the peripheral target tissues. The parasympathetic nerves (PSNS) are autonomic (aka "visceral") branches of the peripheral nervous system (PNS). Parasympathetic nerve fibers arise from the central nervous system with the S2, S3, and S4 spinal nerves and from the third, seventh, ninth, and tenth cranial nerves.The parasympathetic nervous system uses chiefly acetylcholine (ACh) as its neurotransmitter, although other peptides (such as cholecystokinin) may act on the PSNS as a neurotransmitter.
Nerves that leave the brain directly are called?
Cranial nerves
What body system sends messeges to one part of your body to another?
In humans there are two main systems for carrying messages from one part of the body to another: the nervous system and the blood.Nerve cells (neurons) carry rapid impulses to precise locations. Every time a muscle contracts it is the result of a message arriving from a nerve cell; nerves stimulate some glands, too, for example the sweat glands in the skin.The blood circulates continuously, and in it will be any hormones that have been secreted by endocrine(hormone-producing) glands. The message, in the form of the hormone, travels much more slowly than a nerve impulse, but the effect is much longer-lasting.Apart from endocrine messaging, there are two other, more local, systems:* paracrine: this system of signaling involves compounds being secreted by a cell and traveling a short distance to exert an effect on other cells nearby. A good example of this is the release of neurotransmitters (such as acetylcholine) to bridge the gap (synapse) between two neurons. * autocrine: this term refers to the release by a cell of a compound that has an effect on that same cell (hence "auto-"). The signal compound may leave the cell and stimulate a receptor embedded in the cell membrane, as if it were a chemical from another cell, or it may remain within the cell, simply carrying a message from one part of the cell to another.

What are the twelve pairs of nerves that make up the PNS called?
There are 32 pars of spinal nerves that leave the brain and spinal chord to form the preipheral nervous system.

Where do nerves go when they leave the ganglion in the crayfish?
After nerves leave the gaglion they go to the, Intestine
Many nerves leaves from ganglion where these nerves go?
After nerves leave the gaglion they go to the, Intestine
Multiple sclerosis is a disease in which immune system attacks the body's nerve cells?
Yes, sort of. In MS patients, leukocytes have crossed the blood-brain barrier and have entered into the central nervous system. There they attack the oligodendrocytes and the myelin sheaths they have produced to protect nerve axons. This can directly cause damage to the nerve or it can leave the nerve unprotected. Also, it greatly slows down the action potential in affected neurons, inhibiting nerve functioning in inflicted areas.
Can brain-dead people hear?
No, the brain dead body cannot hear because there is no activity of the nervous system. The ears must have the nervous system functioning and the brain to perceive sound. The person's Spirit might hear you in the room if he or she is there but usually they leave the body right way and leave earth.
Nerves that leave the brain directly are called?
Cranial nerves
Where do blood vessels and nerves enter and leave the bone?
All bones have foramen in them. These are canals or openings through which nerves and blood vessels go.
How do you leave tutoring?
Must say you are not feeling well or you cannot concentrate or get on their nerves so you can leave
Where do the nerves leave from each ganglion in a crayfish?
They go to the intestine.
What are the fibers that enter and leave the sympathetic chain without synapsing form structures are called?
Splanchnic nerves
An opening or passage in bones where blood nerves enter and leave?
FORAMEN - Opening or passage in bones where blood vessels and nerves enter and leave. The foramen magnum is the opening of the occipital bone through which the spinal cord passes.
