Neurotransmitters are formed in a presynaptic neuron and stored in small membrane-bound sacks, called vesicles, inside this neuron. When this neuron is activated, these intracellular vesicles fuse with the cell membrane and release their contents into the synapse, a process called exocytosis.
Modern timekeeping defines a day as the sum of 24 hours â but that is not quite correct. The Earth's rotation slows down over time. So in terms of solar time, most days are a little longer than 24 hours.
The simple answer is just over 24 hours.More details: A day on Mars is 24 hours, 39 minutes and 35 seconds That's the solar day. The rotation period or sidereal day i â¦ sa couple of minutes less. For comparison, on Earth the solar day is 24 hours and the sidereal day is about 23 hours and 56 minutes.
