Cell signalling. Computer artwork of neurotransmitter molecules travelling between a neurone (nerve cell,green) and an effector cell (orange). The junction between the two cells is called a synapse. Signalling molecules,such as neurotransmitters,allow cells to respond to changes in their environment and to coordinate this response. They can trigger a number of reactions,including changes in metabolism and gene expression. Cell communication over short distances,as shown here,is known as paracrine signalling | |
