In your presentation, you MUST address the following: Describe the normal anatomy and physiology of the vagus nerve. Can I live without a vagus nerve? Explain why/why not. Explain, using at least one...

Vagus Nerve
Vagus Nerve
Anatomy
Among the cranial nerves, the vagus nerve is the longest. 
It encompasses sensory and motor fibres and has the greatest proportion in the body due to its passage through the thorax and neck to the abdomen (Fitchett et al., 2021). 
It contains visceral and somatic afferent fibres, as well as special and general visceral efferent fibres. 
The heart, primary blood vessels, lungs, airways, stomach, intestines, and oesophagus are all innervated by it (Farmer et al., 2021). 
(Mughrabi et al., 2021)
It is related to the sixth and fourth pharyngeal arches' derivatives. 
Although it is referred to as a single nerve, it is essentially a pair of nerves that originate from the right and left sides of the brain stem's medulla oblongata (Mughrabi et al., 2021).

Physiology 
The vagus nerve regulates internal organ processes like heart rate, respiratory rate, digestion, and vasomotor activity as well as reflex actions like sneezing, coughing, vomiting, as well as swallowing. 
The vagus nerve is also involved in satiation after eating. The vagus nerve controls a portion of the heart's parasympathetic innervation, which is held by the thoracic ganglia.
The vagus nerves are crucial in stimulating gastric secretion (Farmer et al., 2021).
(Orosz et al., 2014)
The vagus nerve regulates several voicebox and throat muscles. 
The vagus nerves also conduct sensory data from the inner organs back into the brain.
It functions on the neck muscles that are responsible for speech and swallowing (Mughrabi et al., 2021).

Can I Live Without a Vagus Nerve?
No. I can not live without a vagus nerve as it is among the body's most crucial nerves. 
The vagus nerve regulates many crucial functions of human physiology, such as heart rate, sweating, blood pressure, speaking, and even digestion (Mughrabi et al., 2021).
The absence of the Vagus nerve can not only affect the secretion of gastric acid but also the processes of other body systems that respond to this nerve.
It can cause gastroparesis, which is when food does not pass through the...
