32 views2 pages
Document Summary
Bio 380 lecture 22 head and neck. The oral cavity is close to the nasal pits. The palate separates the oral and nasal cavity within the sixth to tenth week. A cleft palate means an incomplete fusion. It depends on when and where the fusion occurred: palate formation affects the lips. There are no teeth postnatal; the figure on slide 10 is wrong. The palate forms after the opening of the oral cavity and before the nasal cavity forms. The nasal placodes form the nasal pits. Through the nasal choanae are the openings to the air sinuses that fill your facial bones. The pituitary gland, which is the chief of the endocrine gland, develops simultaneously. It is formed by three lobes: the anterior two lobes are glandular tissue, the posterior lobe is neural tissue. It derives from two sources: the neural tube and the oral cavity.
