Synaptic Transmission Synaptic Transmission Of Nerve Impulse Youtube In my 2 minute neuroscience videos i explain neuroscience topics in 2 minutes or less. in this video, i discuss synaptic transmission. i describe the synapse. In this mini lecture, dr mike explains synaptic transmission. the process of a neuron sending a signal to an excitable cell (i.e. neuron, muscle, or gland).
2 Minute Neuroscience Synaptic Transmission Youtube Learn how neurons communicate with each other through electrical and chemical signals in this animated video. discover the basics of neural conduction, action potential, and synaptic transmission. Figure 42.2.2 42.2. 2: the (a) resting membrane potential is a result of different concentrations of na and k ions inside and outside the cell. a nerve impulse causes na to enter the cell, resulting in (b) depolarization. at the peak action potential, k channels open and the cell becomes (c) hyperpolarized. Chemical transmission requires the following steps: 1. synthesis of the neurotransmitter in the presynaptic nerve terminal. 2. storage of the neurotransmitter in secretory vesicles. 3. regulated release of neurotransmitter in the synaptic space between the pre and post synaptic neurons. 4. Figure 35.6.1 35.6. 1: communication at a chemical synapse: communication at chemical synapses requires release of neurotransmitters. when the presynaptic membrane is depolarized, voltage gated ca2 channels open and allow ca2 to enter the cell. the calcium entry causes synaptic vesicles to fuse with the membrane and release neurotransmitter.
