Which part of the peripheral nervous system comprises the whole complex of nerves, fibres, a ganglia, and plexuses?

Which part of the peripheral nervous system comprises the whole complex of nerves, fibres, a ganglia, and plexuses? Correct Answer Visceral nervous system

The correct answer is the visceral nervous system

Key Points

  1. The visceral nervous system is a part of the peripheral nervous system
  2. The peripheral nervous system comprises all nerves of the body associated with the central nervous system
  3. The functional division of the peripheral nervous system our system is divided into two divisions called the somatic nervous system and autonomous nervous system

  4. Somatic sensory neuron Convey perceived special senses and somatic senses somatic motor neurons innervate skeletal muscles which produce voluntary movements

  5. The autonomic nervous system is also known as the efferent or motor visceral nervous system it controls the autonomic functions of the body such as respiration digestion light to fight response reflexes reflex action.

  6. Operates without conscious control originally named as automatic because it was thought to be self-governing without control by the central nervous system, centres in the central nervous system like the hypothalamus regulate autonomic reflex

  7. It relays information from the central nervous system to involuntary organs and smooth muscles it controls the function of visceral organs such as cardiac muscles smooth muscle etc

Additional Information

  1. the autonomic nervous system is of two types sympathetic and parasympathetic nervous system
  2. The sympathetic nervous system is associated with flight or flight responses this is characterised by the release of large quantities of epinephrine from the adrenal gland an increase in heart rate an increase in cardiac output skeletal muscle dilation cutaneous and gastrointestinal contraction pupillary dilation bronchial dilation piloerection occurs.
  3. parasympathetic nervous system predominates in quiet rest and digest conditions the main purpose of the parasympathetic nervous system is to conserve energy to be used later and regulate bodily activities like digestion and urination.

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. What do we see when we look at an object?
