Brain And Nervous System

Our best articles related to Brain and nervous system

The brain is considered the control center of the body with the nervous system acting as the highway, delivering messages from the brain to different parts of the body. These vital systems of the body are being performed even when the body and other bodily systems are in a resting state.
A brain tumor is an abnormal growth of tissue in the brain. The tumor can either originate in the brain itself, or come from another part of the body and travel to the brain (metastasize). Brain tumors may be classified as either benign (non-cancerous) or malignant (cancerous) depending on their behavior.

Autonomic Nervous SystemWhat does erectile dysfunction, Parkinson's disease and constipation have in common? Improper function of the autonomic nervous system.
Nervous system diagramAnatomical brain and head charts, commonly available as 22 by 28-inch plain paper or laminated pages, or flip charts, are ideal patient and student education tools. These charts, with their wealth of anatomical diagrams and lengthy but comprehensible explanations, offer ...
Brain memory improvementThe nervous system relies on a high-speed communications network to alert the brain to information that affects all areas of the body.

Sympathetic and parasympathetic divisions typically function in opposition to each other. But this opposition is better understood as complementary in nature rather than antagonistic. For an analogy, one may think of the sympathetic division as the accelerator and the parasympathetic ...
The afferent parasympathetic sensations are mostly unconscious visceral motor reflex sensations from hollow organs and glands that are transmitted to the CNS. While the unconscious reflex arcs normally are undetectable, in certain instances they may send pain sensations to the ...
Parasympathetic Nervous SystemThe pelvic splanchnic nerves, S2-4, work in tandem to innervate the pelvic viscera. Unlike in the cranium, where one PSN was in charge of one particular tissue or region, for the most part the pelvic splanchnics each contribute fibers to ...
Central Nervous SystemThis article theorizes on the influences of whole body vibration on the central nervous system. More specifically, it identifies the potential pathways by which its benefits are obtained.
parasympathetic nervous system (PSNS) is one of the three main divisions of the autonomic nervous system (ANS). The ANS is responsible for regulation of internal organs and glands, which occurs unconsciously. The parasympathetic system specifically is responsible for stimulation of ...
Parasympathetic Nervous SystemThe parasympathetic nerves (PSN) 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 ...
The oculomotor nerve is responsible for several parasympathetic functions related to the eye. The oculomotor PNS fibers originate in the Edinger-Westphal nucleus in the CNS and travel through the superior orbital fissure to synapse in the ciliary ganglion located just ...
Parasympathetic Nervous SystemThe parasympathetic nervous system uses chiefly acetylcholine (ACh) as its neurotransmitter, although other peptides (such as cholecystokinin) may act on the PSNS as a neurotransmitter. The ACh acts on two types of receptors, the muscarinic and nicotinic cholinergic receptors. Most ...
