Lorraine and Albert are discussing neurotransmitters while getting ready for an exam. Lorraine maintains that dendrites receive and solve both excitatory messages.Albert on the other hand, argues it’s endorphins that complete the selection process.Who is correct?
A-Neither Lorraine nor Albert
B-Both Lorraine and Albert
C-Albert
D-Lorraine
The correct answer is D- Lorraine. Dendrites do receive and solve both excitatory and inhibitory messages, not just excitatory messages. Endorphins, however, are not involved in the selection process of neurotransmitters.
B-Both Lorraine and Albert
To determine who is correct, we need to understand the roles of dendrites and endorphins in the process of neurotransmission.
Dendrites are the branch-like extensions of neurons that receive incoming signals or messages from other neurons. These signals can be either excitatory or inhibitory. Excitatory messages promote the generation of an electrical signal called an action potential, while inhibitory messages prevent the generation of an action potential.
Endorphins, on the other hand, are a type of neurotransmitter that are involved in pain regulation and the promotion of feelings of pleasure and well-being.
Based on this information, it is clear that Lorraine is incorrect in stating that dendrites "solve" messages. Dendrites receive messages and determine whether these messages are excitatory or inhibitory, but they do not solve or complete the selection process.
Albert's argument that endorphins are involved in the selection process is also incorrect. Endorphins are not directly involved in the selection process of neurotransmission. They have a different role in the modulation of pain and mood.
Therefore, the correct answer is A-Neither Lorraine nor Albert. Neither of them accurately describes the role of dendrites or endorphins in the selection process of neurotransmission.
