The Anatomy Of Salivation Of Swallowing

Question 1

What are some features of the composition of salvia?

Answer 1

Mostly water, hypotonic, rich in postassium and bicarbone, mucins help wiht lubrication,amylase and lingual lipase and contain a variety of immiune problems, amylase and lingual lipase, adn contains a diversity of immune proteins

Question 2

What are the functions of salvia?

Answer 2

Lubricatin gthe mouth and the structures, and needs to be moist. Transmission of disease, digestions, a solvent for the taste molecules, antibacterial affects, lubrication and moistening of food

Question 3

What is xerostomia?

Answer 3

A dry mouth due to lack of the salvia, difficulty eating, and the a red and swollen

Question 4

What are the three different salviary galnds?

Answer 4

The partoid gland, the submandibular gland and the sublingual gland

Question 5

What isa the neural regulation of the secrete ion of salvia?

Answer 5

Ormiarly neural and autonomic secretion, parasymapthei is the main diriver of secretion, sympatheic also causes the secretion of small amounts of salvia but also causes vasconstriction,

Question 6

What can swelling on the sid eof the face is called?

Answer 6

Patoidoitis is inflammation of the partoid gland, mumps and you can get enceptahlotis, increptibly painful as the sheath around this is very tight

Question 7

At are the free phases of swallowing?

Answer 7

Oral preparatory phase, pharyngeal phase, the osephgeal phase

Question 8

What is the oral phase of of swallowing?

Answer 8

Voluntary, pushes the bolus towards the pharynx once bolus touches the pharyngeal wall the pharyngeal phase begins

Question 9

Describe the pharyngeal phase of swallowing?

Answer 9

Involuntary, the soft palapte seals off the nasopharynx,nphraryngeal constriction pushes the bolus downwards,larynx elevates closes the epiglottis, vocal cords adduct, and opening pf the upper osephageal spinchter

Question 10

Osephagela phase

Answer 10

Involuntary, the closure of the upper osephageal spincther, peristaltic wave carries the bolus down into the osephagus

Question 11

What is the neural control of swallowing and the gag reflex

Answer 11

Mechanoreceptors, glossopharyngeal nerve, the medulla, vagus nerve and the pharyngeal constrictors

Question 12

How do we prevent the gastro osephagela refilux.

Answer 12

The functional spincther is formed from smooth muscle of the which gets pressure compressed when the intra abdominal pressure rises, mucosal rosette at cardia and the acute entry of the oesophagus
