The progression of a muscle structure over time, from its formation to its mature state. Muscle structures are contractile cells, tissues or organs that are found in multicellular organisms.

The process whose specific outcome is the progression of the hemocyte over time, from its formation to the mature structure. Hemocytes are blood cells associated with a hemocoel (the cavity containing most of the major organs of the arthropod body) which are involved in defense and clotting of hemolymph, but not involved in transport of oxygen.

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

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

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

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

The process whose specific outcome is the progression of the somatic muscle over time, from its formation to the mature structure. Somatic muscles are striated muscle structures that connect to the exoskeleton or cuticle.

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

The biological process in which a synapse between a motor neuron and a muscle is initially formed.

The process in which an axon recognizes and binds to a set of cells with which it may form stable connections.

Separation of axons away from a bundle of axons known as a fascicle.

The collection of neuronal projections into a bundle of rods, known as a fascicle.

Separation of a motor axon away from a bundle of axons known as a fascicle.

The process whose specific outcome is the progression of the ventral midline over time, from its formation to the mature structure. In protostomes (such as insects, snails and worms) as well as deuterostomes (vertebrates), the midline is an embryonic region that functions in patterning of the adjacent nervous tissue. The ventral midline in insects is a cell population extending along the ventral surface of the embryo and is the region from which cells detach to form the ventrally located nerve cords. In vertebrates, the midline is originally located dorsally. During development, it folds inwards and becomes the ventral part of the dorsally located neural tube and is then called the ventral midline, or floor plate.

The process whose specific outcome is the progression of the central nervous system over time, from its formation to the mature structure. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain and spinal cord. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord.

The process whose specific outcome is the progression of the ventral cord over time, from its formation to the mature structure. The ventral cord is one of the distinguishing traits of the central nervous system of all arthropods (such as insects, crustaceans and arachnids) as well as many other invertebrates, such as the annelid worms.

The process whose specific outcome is the progression of the stomatogastric nervous system over time, from its formation to the mature structure.

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.
