The hard palate is a thin horizontal bony plate made up of two bones of the facial skeleton, located in the roof of the mouth. The bones are the palatine process of the maxilla and the horizontal plate of palatine bone. The hard palate spans the alveolar arch formed by the alveolar process that holds the upper teeth (when these are developed).
Nonkeratinized squamous epithelium covers the soft palate, inner lips, inner cheeks, the floor of the mouth, and ventral surface of the tongue. Keratinized squamous epithelium is present in the gingiva and hard palate as well as areas of the dorsal surface of the tongue. [8] [9]
The palate (/ ˈ p æ l ɪ t /) is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity . [ 1 ] A similar structure is found in crocodilians , but in most other tetrapods , the oral and nasal cavities are not truly separated.
A mouth assessment is performed as part of a patient's health assessment. The mouth is the beginning of the digestive system and a substantial part of the respiratory tract . Before an assessment of the mouth, patient is sometimes advised to remove any dentures.
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest. It is the most important bone in the midface.
Early fossil reptiles retained the arrangement seen in more primitive vertebrates, but in mammals, the lower surface of the palatine became folded over during evolution, forming the horizontal plate, and meeting in the midline of the mouth. This forms the rear of the hard palate, separating the oral and nasal cavities, and making it easier to ...
In the human mouth, the incisive foramen (also known as: "anterior palatine foramen", or "nasopalatine foramen") is the opening of the incisive canals on the hard palate immediately behind the incisor teeth. It gives passage to blood vessels and nerves. The incisive foramen is situated within the incisive fossa of the maxilla.
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] ... Its roof is formed by the hard palate.
