World of Biology on Instagram: "Neurotransmission is the process by which nerve cells, or neurons, communicate with each other to transmit signals throughout the body. This is what neurotransmission looks like: an electrical impulse travels along the axon of a neuron until it reaches the synaptic terminal, where it triggers the release of chemical messengers called neurotransmitters. These neurotransmitters cross the tiny gap known as the synaptic cleft and bind to receptors on the neighboring n

mathswithmuza on Instagram: "Lebesgue rectangles are a simple geometric way to visualize how the Lebesgue integral builds up area by looking at slices of the range rather than slices of the domain. Instead of cutting the x-axis into intervals and stacking vertical rectangles, the Lebesgue approach groups together all points where the function takes values within a certain band. For each horizontal “slice” of height Δy, you look at the set of x-values where the function falls inside that slice, a
