Target type: cellularcomponent
Non-terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. [GOC:nln]
A varicosity is a localized dilation or swelling along an axon, specifically a nerve fiber. It's a specialized structure that plays a crucial role in synaptic transmission, the communication between nerve cells. Within a varicosity, you'll find a concentrated collection of synaptic vesicles, tiny membrane-bound sacs that contain neurotransmitters. These neurotransmitters are the chemical messengers that allow signals to be passed from one neuron to another. The varicosity itself is enveloped by the axonal membrane, and it's often positioned near the target cell, allowing for efficient release of neurotransmitters into the synaptic cleft, the narrow space between the varicosity and the target cell. Furthermore, varicosities may contain various organelles, such as mitochondria, which provide energy for the process of neurotransmitter synthesis and release. The cytoskeletal components within a varicosity contribute to its structural integrity and help maintain the positioning of the synaptic vesicles. In essence, the varicosity acts as a specialized compartment within the axon, specifically designed to store, synthesize, and release neurotransmitters, facilitating effective communication between neurons.'
