a. mechanical b. voltage c. chemical d. pressure e. all of the above; Provide a discussion about a synapse and begin with a definition and a comparison of the two categories (electrical and chemical). Chemical synapses are specialized junctions through which cells of the nervous system signal to one another and to non-neuronal cells such as muscles or glands. • Presynaptic ending: - swelling of the axon terminal. A) Synapse - a junction between 2 nerve cells, or between a nerve cell and an effector. Synapses in the Nervous System - Verywell Health Describe one advantage and one disadvantage of having synapses between ... Chemical synapse. At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. 2- Point out the advantages and disadvantages of chemical synapses as compared to electrical ones. Describe the advantages and disadvantages of electrical and chemical synapses eletrical is fastest and bidirectional, but signal is diminished.. chemical is a little slower (not by much) and can generate a wide variety of responses and can amplify an electric current Explain how excitatory and inhibitory postsynaptic responses can be produced Neuroscience - Synaptic Transmission and the NMJ - Quizlet PDF Chemical and Electrical Synapses 2) Chemical synapse However, they provide the nervous system with many benefits that could not be achieved without them: They ensure that information flow is in one direction. Terminals of presynaptic axon end up in small swellings called synaptic boutons. ii) 2-way travel. Electrical synapses thus work by allowing ionic current to flow passively through the gap junction pores from one neuron to another. Synapses | Anatomy and Physiology I | | Course Hero Robotics. The neurotransmitter . Give two advantages and two disadvantages to using the biuret reaction to Electrical synapses also have to be much smaller so the channel proteins can reach from one cell to another. - Amplification: Sufficient acetylcholine is released at neurotransmitter junction by each nerve impulse to excite the post-synaptic membrane to produce respond in the muscular fiber , but there is a steep concentration gradient between the inside and the outside of .
