گیرنده (Girehandeh) refers to a device or component that receives signals or information. In various fields, such as telecommunications and electronics, گیرنده plays a crucial role in capturing data transmitted over distances. For example, in radio systems, a گیرنده picks up radio waves and converts them into sound. In the context of biology, a گیرنده can also refer to a receptor, which is a protein molecule that receives and responds to chemical signals. These receptors are essential for processes like cell communication and can be found on the surface of cells, interacting with hormones or neurotransmitters to trigger specific responses.
