The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster.

The process whose specific outcome is the progression of the mushroom body over time, from its formation to the mature structure. The mushroom body is composed of the prominent neuropil structures of the insect central brain, thought to be crucial for olfactory associated learning. These consist mainly of a bulbous calyx and tightly packaged arrays of thin parallel fibers of the Kenyon cells.

Any process that activates or increases the frequency, rate or extent of actin polymerization.

Any process that activates or increases the frequency, rate or extent of actin polymerization.

Ensuring that tracheal cells form and maintain tubular structures with the correct size and shape for their position in the network. This is essential for efficient flow of gases through the tracheal network.

Long distance growth of a single axon process involved in cellular development.

Long distance growth of a single axon process involved in cellular development.

Any process that modulates the frequency, rate or extent of axonogenesis, the generation of an axon, the long process of a neuron.

The assembly of actin filament bundles; actin filaments are on the same axis but may be oriented with the same or opposite polarities and may be packed with different levels of tightness.

Any process that modulates the frequency, rate or extent of the assembly of a filopodium, a thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone.

Any process that activates or increases the frequency, rate or extent of the assembly of a filopodium, a thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone.

Any process that increases the rate, frequency or extent of myofibril assembly by organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

The aggregation, arrangement and bonding together of proteins to form the actin-based thin filaments of myofibrils in striated muscle.

Filaments formed of actin and associated proteins; attached to Z discs at either end of sarcomeres in myofibrils.

The cytoplasm of a muscle cell; includes the sarcoplasmic reticulum.

Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached.

The migrating motile tip of a growing nerve cell axon.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
