Explanation:

Neural System:

• Theneural systemis the major controlling and regulatory system of the human body.
• It acts as the centre of all the mental activities which is taken care of by the brain and the spinal cord.
• The human nervous system consists of the brain, spinal cord and nerve cells.
• Homeostasis is maintained in the body by the neural system only.
• It sends and receives signals from the brain and the body.
• Any malfunctioning of the organs or organ systems is taken care of by them.
• With the help of nerve cells, they provide commands to the body to act in an emergency situation.

Spinal Cord:

• The spinal cord is a part of the human nervous system.
• There are 31 spinal nerves extending out from the left and right sides of the spinal cord.
• The nerves are labelled by the vertebrae region and numbered for the vertebra nearest to the nerve exit from the spinal canal.
• It is the structure of a flexible column comprised of 26 bones in a multi-covered shape arising naturally due to vertebral and disk shape, rib cage and inclination of the sacral endplate.
• It helps in providing resistance to the axial sagittal plane.
• It supports the mass of the body/ head and withstands external forces.
• Allows for mobility and flexibility to absorb energy and protect against any impact.
• It helps in controlling and maintaining the central, autonomous and peripheral nervous system.

Sympathetic and Parasympathetic nervous systems:

• The sympathetic nervous system drives 'flight or fight' responses while the parasympathetic nervous system predominates the 'rest and digest responses.
• The parasympathetic nervous system decreases the heart rate while the sympathetic increases.
• The sympathetic nervous system dilates pupils, relaxes airways, inhibits the activity of the stomach, relaxes bladders etc.
• The parasympathetic nervous system stimulates the activities of the stomach and intestines, contracts the bladder, inhibits the release of glucose and stimulates the gall bladder.​

Concept:-

Spinal nerves: it is a part of the peripheral nervous system.

• Spinal nerves are the path of communication between the spinal cord and the specific region of the body.
• these nerves leave the vertebral column by passing through the intervertebral foramina except the first spinal nerve which emerges b/w the occipital bone and atlas (first vertebra).

Explanation:-

• There are 31 pairs of spinal nerves that originate from both sides of the spinal cord.

1. Slow heart beat
2. Accelerate heart rate
3. Stimulate salivary secretion
4. Stimulate peristalsis

Concept-

• The parasympathetic nervous system is composed mainly of the cranial and spinal nerves.
• The preganglionic neurons, arising from either the brain or sacral spinal cord, synapse(meet) with just a few postganglionic neurons which are located in or near the effector organ (muscle or gland).
• The parasympathetic nervous system is responsible for the body's rest and digestion response when the body is relaxed, resting, or feeding.

Key PointsNerves of the parasympathetic nervous system-

• Nerve fibres of the PSNS arise within the central nervous system. The primary nerves involved arecranial nerves. Below are some of the main cranial nerves in the PSNS:
  • Vagus nerve– approximately 75% of all the parasympathetic nerves are vagus nerves. These nerves have branches in many key organs such as the stomach, kidneys, bladder, and reproductive organs.
  • Oculomotor nerve– these nerves are able to help constrict the pupils.
  • Glossopharyngeal nerve– these nerves project to the salivary glands to provide extra salivation to the tongue

Functions of parasympathetic nervous system-

• Parasympathetic nervous system is able to decrease heart rate, especially when at rest after completing physical exercise or after stressful situations.
• It also stimulates salivation of the mouth to enable the easier digestion of food through the enzymes within saliva.
• Digestion is also promoted within the stomachas well as releasing bile for the body to digest fats.
• The PSNS also contracts the bladder so that urination can occur, in addition to being able to move food within the intestines down the digestive tract to enable bowel movements which is called peristalsis.
• When stressed, the PSNS triggers the necessary responses in order to return to homeostasis (the maintaining of balancing internal physiology).
• Without the PSNS, we may either constantly be in a state of elevated stress responseor the regulation of our everyday bodily processes would be dysfunctional, such as being unable to digest food or control our bladder.

Additional Information

• The sympathetic nervous system can:
  • accelerate heart rate,
  • widen bronchial passages,
  • decrease motility of the large intestine,
  • constrict blood vessels,
  • increase peristalsis in the esophagus,
  • cause pupillary dilation,
  • piloerection (goose bumps),
  • perspiration (sweating),
  • raise blood pressure.
