Physiology
The cholinergic system, which is part of the parasympathetic nervous system, stimulates the parietal cells in the stomach to release hydrochloric acid (HCL) through the activation of muscarinic M1 receptors. This is crucial for the digestion of food and the maintenance of gastric pH.

The significant differences between self-etch
primers and total-etch primers are: Wetness of dentine: In total-etch, dentine must be kept moist
after etching to prevent collagen collapse. In self-etch, no rinsing step is required, so
dentine wetness is not critical. Time of application: Total-etch involves separate etching, rinsing,
and priming steps → longer procedure. Self-etch combines etching and priming in one
step → faster. Removal of smear layer: Total-etch completely removes the smear layer
with phosphoric acid. Self-etch modifies and incorporates the smear
layer into the hybrid layer. Bond strength: Both systems can achieve comparable bond strength
to enamel and dentine when properly applied. Hence, bond strength is NOT a significant difference
between the two systems.Explanation

Pathology
Extensive cellulitis is most accurately described by the term "phlegmon Phlegm is a thick, viscous substance produced by the respiratory tract,
especially during a respiratory infection, which can be coughed up from the
lungs or expelled from the nose. It is primarily composed of mucus, dead cells,
and other substances. Phlegmon is a term that is closely related to extensive cellulitis. It refers
to a severe form of cellulitis where the infection has spread deeply into the
subcutaneous tissues and is accompanied by significant inflammation, including
the presence of pus and necrosis. Phlegmon is characterized by intense pain,
swelling, redness, and warmth in the affected area. This condition often
requires aggressive medical management, including intravenous antibiotics and
surgical drainage if an abscess forms. It is an advanced and severe stage of
cellulitis that can lead to systemic infection if not treated properly.
