A series of molecular signals initiated by binding of a ligand to the tyrosine kinase receptor EGFR (ERBB1) on the surface of a cell. The pathway ends with regulation of a downstream cellular process, e.g. transcription.

The process whose specific outcome is the progression of the brain over time, from its formation to the mature structure. Brain development begins with patterning events in the neural tube and ends with the mature structure that is the center of thought and emotion. The brain is responsible for the coordination and control of bodily activities and the interpretation of information from the senses (sight, hearing, smell, etc.).

The process whose specific outcome is the progression of the peripheral nervous system over time, from its formation to the mature structure. The peripheral nervous system is one of the two major divisions of the nervous system. Nerves in the PNS connect the central nervous system (CNS) with sensory organs, other organs, muscles, blood vessels and glands.

The process in which the anatomical structures of the imaginal disc-derived wing are generated and organized. The wing is an appendage modified for flying.

The process whose specific outcome is the progression of the dorsal part of the body over time, from its formation to the mature structure.

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

The process whose specific outcome is the progression of the haltere over time, from its formation to the mature structure. The haltere is the club-shaped 'balancers' found on each side of the metathorax among the true flies (Diptera). They are the much-modified hind wings.

The process whose specific outcome is the progression of the midgut over time, from its formation to the mature structure. The midgut is the middle part of the alimentary canal from the stomach, or entrance of the bile duct, to, or including, the large intestine.

Any process that activates or increases the rate or extent of cell proliferation.

Any process in an organism in which a relatively long-lasting adaptive behavioral change occurs in response to (repeated) exposure to an olfactory cue.

The process in which anatomical structures of the veins on an imaginal disc-derived wing are generated and organized.

Formation of a prolongation or process extending from a cell, e.g. a flagellum or axon.

The process in which a cell in the larval wing imaginal disc becomes capable of differentiating autonomously into a notum cell, if left in its normal environment.

Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.

Any process that activates or increases the frequency, rate or extent of border follicle cell migration.

Any process that modulates the frequency, rate or extent of stem cell differentiation.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
