Xantus Hummingbird Species. Xantus Hummingbird is a medium-sized hummingbird that can only be found in Baja, California. The bird is deemed to be the most distinctive among the few Baja specialty birds. It grows to a length of 3-3.5 inches, and weighs about 3-4 grams upon maturity. It was named after a Hungarian zoologist, John Xantus de Vesey.
The nasal septum, the division between the left and right airways of the nose, is made of three structures: the vomer bone, perpendicular plate of ethmoid bone, and its cartilage.
The nasal septum is a rigid layer that separates the inside of the nose into two cavities, right and left. It consists of a sheet of bone and cartilage covered by mucosa on either side. Mucosa is the name for a moist skin-like cover comparable to the inside of the mouth. The septum is important for both form and function of the nose. If it is deviated, breathing problems may arise (see septoplasty). A hole within the septum is called nasal septal perforation. Although it creates an abnormal internal communication between the two sides of the nose, this by itself causes no harm.
