Question

Match each neural component with its role in synaptic transmission. Drag each item on the left to its matching item on the right. a. neurotransmitters presynaptic b. neuron postsynaptic c. neuron dendrites postsynaptic d. neuron cell body 1. receiving information 2. chemicals that are released into the synapse 3. integrating information 4. sending information

Answer 1

Answer:

a. neurotransmitters presynaptic >>>>  2. chemicals that are released into the synapse

b. neuron postsynaptic  >>>> 3. integrating information

c. neuron dendrites postsynaptic >>>> 1. receiving information

d. neuron cell body  >>>> 4. sending information

Explanation:

Neurons transmit nervous impulses. These cells are composed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli (information) from other cells, and an axon that is a long structure capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis. As it happens in every synapsis between cells when a presynaptic neuron sends information, a neurotransmitter is released. This molecule is a chemical substance that travels through the synaptic cleft to the junctional area and binds to its receptors in the postsynaptic membrane. This binding produces a depolarization of the cell called an excitatory postsynaptic potential. An action potential is initiated and spreads to the rest of the membrane depolarizing it.
