Synapses can be classified by the type of cellular structures serving as the pre- and post-synaptic components. The vast majority of synapses in the mammalian nervous system are classical axo-dendritic synapses (axon synapsing upon a dendrite), however, a variety of other arrangements exist.
Learn how neurons communicate with each other at synapses, the junctions between cells. Explore the mechanisms of chemical and electrical synapses, and the effects of neurotransmitters and receptors.
- Yes, the synaptic cleft is filled with extracellular fluid.
- Each neuron may be connected to up to 10,000 other neurons, passing signals to each other via as many as 1,000 trillion synaptic connections. Meani...
- In the Synaptic Cleft, there are neurotransmitters that are diffusing from one neuron to the next neuron, and then undergoing receptor-mediated end...
- You got confused because both carry a positive charge. I will tell you that speaking of the number of ions, this is almost minor. Yes, we say an in...
- EPSPs are graded potentials that can initiate an AP in the axon, whereas IPSPs produce a graded potential that lessens the chance of an AP in an ax...
- Acetylcholine interacts with postsynaptic receptors a few milliseconds before it is being degraded down by acetylcholinesterase. Then both taken up...
- A primordial neurosecretory apparatus in choanoflagellates was identified and it was found that the mechanism, by which presynaptic proteins requir...
- Because it could cause potential disadvantages: 1. further delaying of response 2. overcrowding of neurotransmitters and too enhanced answer 3. wha...
- They little delay the reaction. The overall synaptic delay and estimated number of synapses (ENOS) of simple tactile reaction neuronal circuits of...
