Question

Parasympathetic nerves arise from which region of the nervous system?
A. Thoracolumbar
B. Cervical
C. Craniosacral
D. Lumbar

Answer 1

One of the answerable outlines for incitement of "rest-and-review" or "feed and breed" exercises is the parasympathetic framework. This occurs when the person's body is very still, predominantly after eating, together with sexual excitement, salivation, lacrimation (tears), urine, absorption, and crap. The activity of the parasympathetic framework can be portrayed as being corresponding to that of the intelligent sensory system. Thus, we can say that it is liable for animating exercises related to the battle or flight reaction.

Complete answer:
The parasympathetic nervous system is portrayed as originating in the craniosacral district, that is, from the brainstem and the sacral plexus. In particular, the parasympathetic sensory system cranially is worried about three of the cranial nerves.
The cranial nerves engaged with the parasympathetic nervous system are the oculomotor, facial, glossopharyngeal, and vagus nerves. This is the place the preganglionic strands are found for the parasympathetic sensory system. Likewise, the sacral parasympathetic core emerging from the second, third, and fourth sacral portions is additionally included.
Inferable from its area, the parasympathetic framework is regularly alluded to as having "craniosacral outpouring", which remains rather than the intelligent nervous system, which is said to have "thoracolumbar surge".

Hence, the correct answer is option (C).

Additional information:
The thoracolumbar belt is an enormous, generally diamond-shaped region of connective tissue composed of the thoracic and lumbar pieces of the profound fascia encasing the characteristic back muscles. The cervical spine functions to give versatility and strength to the head while associating it to the generally stationary thoracic spine. The development of gesturing the head happens transcendently through flexion and augmentation at the joint between the chartbook and the occipital bone.
The principle capacity of the lumbar spine is to manage the heaviness of the body. These vertebrae are a lot bigger in size to retain the pressure of lifting and conveying bulky items.

Note: The parasympathetic sensory system or craniosacral division (i.e., the second significant surge of the ANS) is sorted out to process, absorb, and monitor energy, just as advance rest. Its anabolic capacities incorporate not only those related to the digestion of supplements, yet additionally various defensive reflexes, for example, those that break point heat loss, less energy consumption, and moderate the heart. The PSNS surge comprises preganglionic neurons situated in brainstem cranial nerve cores or the autonomic sections of the sacral spinal rope.
