Any process that modulates the frequency, rate or extent of synaptic growth at neuromuscular junctions.

Any process that activates or increases the activity of an ion transporter.

The assembly and arrangement of a rhabdomere within a cell. The rhabdomere is the organelle on the apical surface of a photoreceptor cell that contains the visual pigments.

The rhythm of the locomotor activity of an organism during its 24 hour activity cycle.

The cellular homeostatic process that preserves a muscle cell in a stable functional or structural state.

The cellular homeostatic process that preserves a muscle cell in a stable functional or structural state.

The chemotaxis process that directs the migration of a photoreceptor cell axon growth cone to its target in the optic lobe in response to a combination of attractive and repulsive cues.

Any process that stops, prevents or reduces the frequency, rate or extent of neuromuscular synaptic transmission.

The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
