The APsolute Recap: Biology Edition - Signal Transduction and the Nervous System
It’s all about maintaining homeostasis in Episode 36! Neurons are specialized cells for conducting electrical signals and releasing chemical neurotransmitters (2:02). Axons conduct an action potential through the movement of sodium and potassium ions (3:00). The message changes from electrical to chemical at a synapse (4:30). Neurotransmitters act as ligands, binding to the postsynaptic membrane (5:20).
The Question of the Day asks (6:44) “Which autoimmune disorder degrades the myelin sheath of an axon? ”
