Parasympathetic Division
...  Parasympathetic division is one of the divisions of the autonomic nervous system that is concerned with digestion, urination and defecation. It has a different effect from that of the sympathetic division because this division involves the body in a state of rest. Unlike the sympathetic, the Parasympathetic decreases respiration and heart rate; hence, it conserves and stores energy instead of  ...

Dual Innervation
...  this system, the body will not function properly. How do dual innervations work and what is their significance in the body? Dual innervations These are innervations affected by two systems, the Parasympathetic and sympathetic nerve systems. They are both present in some organs because of the variety of functions that the organs have to perform. Both systems are anti-thesis to each other;  ...

Testes
...  are necessary for the proper functions of the testes. It is the testicular nerves which are able to innervate the testes with both of these requirements. Innervation is slightly assisted by the Parasympathetic neurons. Sexually-mature testes will produce a much higher concentration of testosterone. It is this androgen which is also known as an anabolic steroid because it increases muscle  ...

Salivary Glands
...  are controlled by the two divisions of the autonomic nervous system. Viscous saliva is released by stimulating the sympathetic impulses. The watery saliva from the serous cells is triggered by the Parasympathetic impulses. Salivating when thinking, smelling, tasting, or dreaming about food is stoked by a physiological response to the stimulation of the Parasympathetic impulses.  ...

Small Intestine
...  of nutrients. The small intestine is innervated by the superior mesenteric plexus. Sensory fibers reach the small intestine through the postganglionic sympathetic fibers and the preganglionic Parasympathetic fibers. Blood supply to the small intestine is provided by the celiac trunk and the inferior mesenteric artery, helped along by a direct route from the superior mesenteric artery.  ...

Tunics
...  is where the most necessary nerve pathway in the gastrointestinal tract is conducted. Nerve fibers and the autonomic nervous system’s ganglion in the myenteric plexus supply sympathetic and Parasympathetic innervaion to the gastrointestinal tract. The Serosa As the outermost tunic, the serosa is the gastrointestinal tract’s wall. This tunic protects all the actions occurring  ...

Pancreas
...  and each acinus contains one layer of epithelial acinar cells. Innervation to the pancreas is done by the branches from the celiac plexus. The glandular functional segment of the pancreas gets the Parasympathetic innervation while the blood vessels receive the sympathetic innervation. The pancreas get blood supply from the splenic artery, a branch of the celiac artery. The pancreatoduodenal  ...

Uterine Tubes
...  by removing it so that the female will live. Blood supply to the uterine tubes is supplied by the uterine and ovarian arteries which are found parallel to the broad ligament. They are innervated Parasympathetically by the hypo-gastric plexus and the pelvic splanchnic nerves. The nerves that connect to the tubes oversee the actions that happen between the blood vessels and the smooth muscle  ...
