Definition: The term "connexional" is a medical term that refers to the connection or linking of two or more nerves, particularly in the brain. It describes how these nerves are connected and how they work together to transmit signals from one part of the body to another. In other words, connexions allow for communication between different parts of the body and help regulate bodily functions such as heart rate, breathing, and sensation. Connexions are also involved in the regulation of pain and temperature sensations,
