Question
Chapter 39, Problem 1RQ
Summary Introduction
To draw:
The diagram of synapse and explain how are signals transmitted from one neuron to another at a synapse.
Introduction:
A synapse is a specialized junction at which neural cell interacts with a target cell. Synapses are the structure that allows a neuron to pass an electric or chemical signal to another targeted neuron. A neuron releases a chemical transmitter that diffuses across the small gap and activates some special receptor on the target cell.

- Describe three mechanisms that stop synaptic transmission.arrow_forwardWhich statement is TRUE about the synapse? Neurotransmitters shuttle the signal back and forth between the pre- and post-synaptic cell. The pre-synaptic cell and post-synaptic cell are in direct contact, allowing the electrical signal to seamlessly flow from one to the other. The action potential jumps from the pre-synaptic cell into the post-synaptic cell. The action potential ends in the pre-synaptic cell and neurotransmitters carry the signal across the synaptic cleft to the post-synaptic cell.arrow_forwardIdentify the following as properties of electrical synapses, chemical synapses, or botharrow_forward
