Motor neurons send messages to muscles to make them contract. What are synapses and neurotransmitters, and how do they function in the nervous system?
Understand the Problem
The text provides an overview of various biological concepts related to the nervous system, endocrine system, immune response, and other physiological processes. It explains structures like motor neurons and synapses, as well as functions of different brain areas, skin layers, and hormonal roles in the body. The question appears to seek information or clarification about these topics.
Answer
Synapses are junctions for nerve communication. Neurotransmitters are chemical messengers that transmit signals across synapses.
Synapses are junctions between neurons where communication occurs. Neurotransmitters are chemical messengers released at synapses to transmit signals to another neuron or muscle cell, enabling communication in the nervous system. They convert an electrical impulse into a chemical signal across the synapse, influencing muscle contraction and other functions.

More Information
Neurotransmitters like acetylcholine are crucial for muscle contraction. Dysregulation can lead to disorders such as myasthenia gravis.
Tips
Confusing synapses with axons or dendrites is common; remember that synapses are specifically for neuron communication.
