Which example involves a cell membrane receiving and sending messages

Explanation: The transmission of the signals though neurons can be defined as an example of cell membrane receiving and sending messages. Any stimulus from the outer environment is transferred to the brain via signal transduction method and then response is generate as a feedback of the stimulus

answer: The membrane plays an important role in communication (signal transmission) within the body.

In the nervous system, neurons communicate with each other and with effector cells (such as muscle cells) through specialized contacts called synapses. Like muscle cells, neurons are cells capable of generating fast electrical pulses on their membrane surface. These electrical pulses are used to transmit signals along the membranes of nerve (and muscle) cells.
