==Introduction==
The avian hard palate contains a slit-like opening called the choanal opening which communicates with the nasal pharynx. Air travels through the choanal opening into the infundibulum then dorsally into the auditory tubes.
==Structure and Function==
*Several rows of caudally facing [[Oral Cavity - Tongue - Anatomy & Physiology#Types of Papillae|conical]] papillae
*Long, narrow, median slit in the pharynx marks the infundibulum
==Histology==
*Numerous [[Oral Cavity - Salivary Glands - Anatomy & Physiology|salivary glands]] are present in the submucosa
*Salivary secretions are mainly mucous with some amylase
*Thick layer of stratified squamous epithelium
