Nerve cells (neurons) convey messages by electrical pulses that pass down the nerve fiber (axon) until they reach the junction with the next neuron or an effector such as a muscle.—Steven Rose
Motor neurons carry out-going signals from the brain or spinal cord to the effector organs, namely the muscles and glands.—Rita L. Atkinson et al.
: a molecule (such as an inducer or a corepressor) that activates, controls, or inactivates a process or action (such as protein synthesis)
What are the cell effectors that induce the physiologic turnover of sphingolipids? An obvious set of such effectors includes steroid hormones, tumor necrosis factor … and other chalones and suppressors of cell growth.—Yusuf A. Hannun and Robert M. Bell
