External Structure The surface of the human nose consists of a frontal portion comprised of the glabella, nasion, alar sidewalls and tip points; a basal portion made up of the columella, nostrils, soft tissues and infra tip lobule; and two other portions called the latter and oblique sections.
Determinants for the shape of the nose. Near the tip of the nose are the nostrils and the columella – the strip of skin between the nostrils. The portion of the nostrils that attach to the cheeks is called the alae. Your nose also has four types of muscles called elevators, depressors, compressors and dilators.
The lateral nasal walls, or sidewalls, each contain three finger-like structures called turbinates. These are made of bony core covered with soft tissue and mucosa. The turbinates regulate nasal airflow and provide mucosa surface area.
