wing disc proximal/distal pattern formation

The establishment, maintenance and elaboration of the proximal/distal axis of the wing disc, a precursor to the adult wing.

The process whose specific outcome is the progression of the respiratory tube over time, from its formation to the mature structure. The respiratory tube is assumed to mean any tube in the respiratory tract.

The process whose specific outcome is the progression of the lung over time, from its formation to the mature structure. In all air-breathing vertebrates the lungs are developed from the ventral wall of the oesophagus as a pouch which divides into two sacs. In amphibians and many reptiles the lungs retain very nearly this primitive sac-like character, but in the higher forms the connection with the oesophagus becomes elongated into the windpipe and the inner walls of the sacs become more and more divided, until, in the mammals, the air spaces become minutely divided into tubes ending in small air cells, in the walls of which the blood circulates in a fine network of capillaries. In mammals the lungs are more or less divided into lobes, and each lung occupies a separate cavity in the thorax.

apposition of dorsal and ventral wing surfaces

The coming together of the dorsal and ventral surfaces of the wing during the conversion of a folded single layered wing disc to a flat bilayered wing.

The process whose specific outcome is the progression of the adrenal gland over time, from its formation to the mature structure. This gland can either be a discrete structure located bilaterally above each kidney, or a cluster of cells in the head kidney that perform the functions of the adrenal gland. In either case, this organ consists of two cells types, aminergic chromaffin cells and steroidogenic cortical cells.

The process by which the anatomical structures of the wing are generated and organized. Morphogenesis pertains to the creation of form. The wing is an appendage modified for flying.

The process, occurring in the embryo, by which the anatomical structures of the limb are generated and organized. Morphogenesis pertains to the creation of form. A limb is an appendage of an animal used for locomotion or grasping.
