Action potential potential, such as plant cells, muscle cells, and the specialized cells of the heart (in which occurs the cardiac action potential). However, the main excitable cell is the neuron, which also has the simplest mechanism for the action potential. Neurons are electrically excitable cells composed, in general, of one or more dendrites, a single soma, a single axon and one or more axon terminals. Dendrites are cellular projections whose primary function is to receive synaptic signals. Their protrusions, known as dendritic spines, are designed to capture the neurotransmitters released by the presynaptic neuron. They have a high concentration of ligand-gated
Pinky and the Brain mice are foiled by trying to speak "New York cabbie" and end up going in circles, the gag credit word was "anophelosis" defined as "morbid state due to extreme frustration". Another common element in nearly each episode is the following exchange (often referred to by the acronym "AYPWIP"): Brain: Pinky, are you pondering what I'm pondering?Pinky: I think so, Brain, but... Pinky's response ends with a non-sequitur such as, "we're already naked", "isn't a cucumber that small called a gherkin?" or "if they called them sad meals, kids wouldn't buy them." Brain would then become furious, often bashing Pinky over
