| 5742928992 | Local Signals | Cells communicating by direct contact | 0 | |
| 5742928994 | Paracrine Signaling | Local regulator released directly onto one cell by another | 1 | |
| 5742928996 | Hormones | Chemical messengers that travel a long distance | 2 | |
| 5742928998 | Reception | Delivery of a signal to a cell | 3 | |
| 5742929000 | G protein-coupled-receptor | Membrane receptor that activates a G protein when a ligand is present. | 4 | |
| 5742929002 | Receptor Tyrosine Kinase | Membrane receptors that attach phosphates to tyrosines | 5 | |
| 5742929004 | Ligand-gated Ion Channel | Receptor opens like a gate when a ligand is present to allow ions in | 6 | |
| 5742929005 | Hormone receptor complex | Intracellular receptors join to form this (not at the cell membrane but rather) | 7 | |
| 5742929006 | Transduction | Involves multiple steps that include turning a sequence of proteins on and off to get a response from the cell | 8 | |
| 5742929007 | Protein Kinases | Does phosphorylation and turns "on" a protein | 9 | |
| 5742929008 | Protein Phosphatases | Does dephosphorylation and turns "off" a protein | 10 | |
| 5742929009 | Second Messengers | Small molecules that diffuse throughout the cell to carry the signal during transduction (such as cAMP) | 11 | |
| 5742933194 | Ligand | Any molecule that bonds specifically to a receptor site of another molecule. Signal molecules; hormones. | 12 |
