Respuesta :
The Vagus Nerve innervates most of the parasympathetic division.It supplies motor parasympathetic fibres to all the organs from the neck to the second segment of transverse colon.Vagus also Controls the skeletal muscle.
Nervous system is divided into two part:
- Somatic Nervous system-
It causes contraction in skeletal nerves and associates with voluntary responses Like breathing,consciousness and awareness.
- Autonomic nervous system-
It controls cardiac and smooth muscle associates with involuntary responses like heart rate,blood pressure etc.
Autonomic Nervous system control internal body organ based on two division (1)Sympathetic division and (2)parasympathetic division,
- Sympathetic division is associated with fight or flight response and response to threat ,to fight ,to run and many more whereas parasympathetic division is referred to by rest and digestion.
- Sympathetic divisions influence various organ systems of the body through connections emerging from THORACIC and upper LUMBAR of spinal cord Refer as Thoraculmbar system.
- Ganglia belong to sympathetic chain Ganglia that runs alongside the vertebral column,There are 23 on either side of spinal cord
- An axon from the central nervous that projects to a sympathetic ganglionic is referred to as preganglionic fibres,it represents the output of a ganglion that directly influences the internal organ.
The Vagus Nerve innervates most of the parasympathetic division.Hence OPTION B is correct Innervation of vagus nerve is not consistent with the sympathetic division.
