Study Notes
- Salivation is provided by different glands and varies in flow rate.
- Saliva is made up of organic and hydro-electrolyte components.
- Organic components include amylase, lipase, lysozymes, albumin, IgA, and kallikrein.
- Hydro-electrolytic components include primary saliva and secondary saliva.
- Salivation is controlled by various factors including the salivary bulbo-protuberantial nucleus, conditioned reflexes, and the sympathetic and parasympathetic nervous system.
- Saliva solubilizes and softens food, aids in digestion, and promotes dental and oral hygiene.
- It has anti-infective properties and prevents dental plaque.
- An increase in salivation can be caused by seeing or smelling food, the esophagogastro-salivary reflex, vomiting, and pregnancy.
- Dry syndrome can cause a decrease in salivation.
- The flow of salivation can affect its excretion time and transition from primary to secondary saliva.
