Why is it important for the sympathetic nervous system to be able to override the kidney's autoregulatory systems?
If blood pressure drops too low due to excessive fluid loss, then the sympathetic nervous system will override renal autoregulation. Sympathetic nerves innervate the afferent arteriole, causing smooth muscle contraction, decreased GFR and decreased fluid loss via urine.
Another effect of the sympathetic nervous system is to stimulate renin secretion by the juxtaglomerular cells, activating the renin-angiotensin-aldosterone system (RAAS). The RAAS increases extracellular fluid volume by increasing sodium reabsorption (see later web page on sodium).

What sympathetic ganglion distributes postganglionic neuronal processes to the kidneys?
The renal plexus is the sympathetic ganglion that distributes postganglionic neuronal processes to the kidneys.
How do the kidneys react to sympathetic nervous system stimulation?
Sympathetic stimulation results in renin secretion by the kidneys and causes a relaxation of the bladder. Accompanied by a constriction of the bladder sphincter, sympathetic stimulation tends to decrease urination and promote fluid retention.
What autonomic plexus controls the kidneys?
The renal plexus is the autonomic plexus that controls the kidneys. It consists of sympathetic and parasympathetic fibers that regulate aspects such as blood flow, filtration, and urine production in the kidneys.
What known functions result from sympathetic innervation into kidneys?
Sympathetic innervation into the kidneys can lead to several functions such as vasoconstriction of renal blood vessels, stimulation of renin release from the juxtaglomerular cells, and reduction in urine production by decreasing blood flow to the kidneys. These responses help regulate blood pressure and maintain overall body fluid balance.
What is the sympathetic ganglion that distributes postganglionic neuron processes to the kidneys and gonads?
The sympathetic ganglion that distributes postganglionic neuron processes to the kidneys and gonads is the prevertebral ganglion called the superior mesenteric ganglion. It is located in the abdominal cavity, anterior to the aorta and just below the origin of the superior mesenteric artery.

What gland activates by sympathetic nervous system produces epinephrine and helps the kidneys regulate sodium and potassium in blood and helps kidneys regulate the water balance?
The adrenal glands
