A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nucleus.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments. Includes processes that control the spatial distribution of actin filaments, such as organizing filaments into meshworks, bundles, or other structures, as by cross-linking.

The directed movement of the nucleus to a specific location within a cell.

The directed movement of cytoplasmic constituents synthesized in the nurse cells to the oocyte.

The process whose specific outcome is the progression of the mesoderm over time, from its formation to the mature structure. The mesoderm is the middle germ layer that develops into muscle, bone, cartilage, blood and connective tissue.

The developmental sequence of events leading to the formation of adult skeletal muscle tissue. The main events are: the fusion of myoblasts to form myotubes that increase in size by further fusion to them of myoblasts, the formation of myofibrils within their cytoplasm and the establishment of functional neuromuscular junctions with motor neurons. At this stage they can be regarded as mature muscle fibers.

The process whose specific outcome is the progression of the larval visceral muscle over time, from its formation to the mature structure.

Maintenance of the structural integrity of the ring canals connecting the female germline cyst.

The controlled self-propelled movement of a cell from one site to a destination guided by molecular cues. Cell migration is a central process in the development and maintenance of multicellular organisms.

Any process in which a microtubule is maintained in a specific location in a cell.

Self-propelled movement of a cell or organism from one location to another.

Any process in which endoplasmic reticulum is transported to, and/or maintained in, a specific location within the cell.

Any process in which a mitochondrion or mitochondria are transported to, and/or maintained in, a specific location within the cell.

Any process in which the nucleus is transported to, and/or maintained in, a specific location within the cell.

Self-propelled movement of an organism from one location to another through the air, usually by means of active wing movement.

The double lipid bilayer enclosing the nucleus and separating its contents from the rest of the cytoplasm; includes the intermembrane space, a gap of width 20-40 nm (also called the perinuclear space).

The outer, i.e. cytoplasm-facing, lipid bilayer of the nuclear envelope; continuous with the endoplasmic reticulum of the cell and sometimes studded with ribosomes.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

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

Cytoplasm situated near, or occurring around, the nucleus.
