Since all the controls are on the camera itself, you donât need a computer in the field. Your home computer is used later to sort, process, and archive the images. In another article, I covered the basics of how to image the Sun, Moon, and planets â bright targets â through a telescope with a digital camera. This article looks at ways advanced amateurs can record dim star clusters, nebulae, and galaxies as part of getting started in deep sky astrophotography.
The pharynx is divided into three regions: 1  Nasopharynx: The nose opens into the nasopharynx via openings called choanae. 2  Oropharynx: The oropharynx begins where the oral cavity ends. 3  Laryngopharynx: The laryngopharynx lies behind the larynx.
It makes up the part of the throat situated immediately posterior to the nasal cavity, posterior to the mouth and superior to the esophagus and larynx. The human pharynx is conventionally divided into three sections: the nasopharynx, the oropharynx and the laryngopharynx. It is also important in vocalization. There are two sets of pharyngeal muscles that act upon the pharynx. These are arranged as an inner layer of longitudinal muscles and an outer circular layer.
