Another difference is that there is a lot of divergence in the Sympathetic Nervous System, as previously discussed, whereas in the Parasympathetic Nervous System there is a lot less, with the ratio of Pre-Ganglionic Neurones to Postganglionic Neurones being , although this is highly dependant on the tissue as in some it is nearly a ratio.  sensory-somatic nervous system and the autonomic nervous system.

Responses to the sympathetic and the parasympathetic learn more here are frequently antagonistic as exemplified by the in opposing effects on the heart rate and gut motility.

The transmission of essay on the autonomic nervous system nerve impulse across junctions such as synapses occurs through the release of humoral chemical messenger from the prejunctional nerve endings, which bridges the gap at the synapses, and thus activates a receptor in the organ supplied or in another nerve cell.

Bervous chemical transmitters involved differ systen sympathetic and parasympathetic divisions. The sympathetic nervous system consists of a chain of ganglia lying on either side http://ogneupor.info/5/g-12.php vertebral column. Preganglionic sympathetic nerve fibers leave the spinal cord between the first thoracic and the second lumbar segments.

Sympathetic activity is initiated from the reticular formation of the medulla oblongata and pons and from centres in hypothalamus. The brainstem sympathetic auyonomic, which have an intrinsic activity of their own, are regulated by many essay on the autonomic nervous essay on the autonomic nervous system including impulses from cortex, limbic lobes and hypothalamus, neural afferents that interact at the level of the brainstem centres and at higher centres, and changes in the physical and chemical properties of the extracellular fluid, including essay on the autonomic nervous system circulating levels of hormones and substrates.

In addition, the sympathetic system releases essay on the autonomic nervous system from the adrenal medulla, which enters the blood stream producing widespread effects throughout the body. Noradrenaline, adrenaline and dopamine are the naturally occurring catecholamines and function as neurotransmitters within the central nervous system.

Catecholamine s are synthesized from the amino- acid tyrosine, which is sequentially hydroxylated to form dihydroxyphenylalanine dopa essay on the autonomic nervous system, decarboxylated to form dopamine and hydroxylated to form noradrenaline.

In the adrenal medulla and in those central neurons utilizing adrenaline as neurotransmitter, learn more here is N-methylated to adrenaline. Catecholamines are stored in adrenal medulla essay disappointment sympathetic nerve endings.

Metabolism does not play an important role in terminating the action of endogenously released catecholamines. The majority http://ogneupor.info/15/b-55.php catecholamines released from nerve endings re-enter the nerve essay on the autonomic nervous system, thereby terminating the in action on the receptors. Some noradrenaline released re-enters the nerve endings limiting further release of noradrenaline, thus acting as a release essay on the autonomic nervous system mechanism.

They have a higher affinity for adrenaline than for noradrenaline and are responsible for bronchial muscle relaxation, skeletal muscle vasodilation and uterine relaxation. They are also present on adipocytes and mediate lipolysis.

The essay autonomic system on nervous commit error: Hence, this is irrelevant.

The parasympathetic preganglionic neurons are located in cranial and sacral portions of the spinal cord. The ganglia lie close to the innervated organ, so that the preganglionic nerves are long and postganglionic nerves are essay on the autonomic nervous system. The parasympathetic tue system innervates the heart, the gastrointestinal tract, the genitourinary system, iris and the salivary glands.

Ach serves as the neurotransmitter at the postganglionic parasympathetic nerve endings. Ach is also the neurotransmitter at all autonomic ganglia, i. In addition to autonomic nervous system, Ach is the neurotransmitter at the somatic nerves supplying the skeletal muscles neuromuscular junction. Nerves that release Ach are said to be cholinergic.

These are located primarily on parasympathetic effecter cells in smooth muscle, cardiac muscle, and the glandular epithelium.

They are selectively stimulated by muscarine and blocked by atropine. The muscarinic M receptors are further divided into M 1 ,M 2and Nervouw 3 receptors.
