==Structure and Function of the Gingiva==

==Structure and Function of the Gingiva==

*Mucosal tissue over [[Alveolar Bone|alveolar bone]]

Gingiva is mucosal tissue over [[Alveolar Bone|alveolar bone]]. It has a stratified squamous epithelium, with some keratinisation. It resists friction of food during [[Mastication|mastication]] by being tightly bound to the underlying bone. It recedes with age, exposing the cervical part of the tooth. It is usually salmon pink in healthy animals. A colour change indicates pathology.

==Vasculature and Innervation of the Gingiva==

 

===Vasculature and Innervation of the Gingiva===

*Superior and inferior alveolar arteries  

The gingiva is supplied by the '''superior''' and '''inferior alveolar arteries'''.

*Blood vessels in the dental [[Pulp - Anatomy & Physiology|pulp cavity]] and a single branch in each major elevation of the [[Crown|crown]]

There are blood vessels in the dental [[Pulp - Anatomy & Physiology|pulp cavity]] and a single branch in each major elevation of the [[Crown|crown]].

*From trigeminal nerve ([[Cranial Nerves - Anatomy & Physiology|CN V]])

Innervation is from the '''trigeminal nerve''' ([[Cranial Nerves - Anatomy & Physiology|CN V]]).
