Neurons in the parasympathetic pathway use which neurotransmitters?

Kay [80]

<h2>Acetylcholine</h2>

Explanation:

Acetylcholine is a chemical that is found between the nerve synapses, or gaps, between nerve cells. When activated, it causes the contraction of skeletal muscles and activates glandular functions in the endocrine system. Think of acetylcholine as a mailperson; residents cannot receive their mail until he or she comes and delivers it to the mailbox. Like mailpersons who deliver the mail and move on to the next house, acetylcholine acts quickly and does not hang around. As a result, acetylcholine is rapidly broken down by another chemical substance called cholinesterase.
Acetylcholine was the first neurotransmitter scientists discovered, as well as the most abundant neurotransmitter in the body. A neurotransmitter is a chemical that is released by a neuron, or nerve cell, that sends a signal to another neuron across a synapse. The neurotransmitter binds to receptors to affect how the signal is received. The purpose of the neurotransmitter is to either amplify or inhibit the signals sent between the neurons.
Acetylcholine plays an important role in the signal of muscle movement, sensation of pain, learning and memory formation, the regulation of the endocrine system and rapid eye movement (REM) sleep cycles.

Through which microscope were cells first observed?

poizon [28]

Compound microscope

<h3>Further explanation</h3>

In 1665, Robert Hooke used a compound microscope to observe cells. Hooke observes the cell walls of dead plants (in the form of cork) when they appear under a microscope. He named it the cell because it looked similar to a cellula or small room inhabited by monks.

Development of microscopy:

1590: Hans and Zacharias Janssen, as Dutch lens grinders, mounted two lenses in a tube to produce the first compound microscope.
1660: Robert Hooke published <em>Micrographia</em>, containing detailed observations of biological materials made with the best compound microscope.
1676: Anton van Leeuwenhoek was the first person to observe a live cell under a microscope, i.e., the algae Spirogyra.
1931: Ernst Ruska constructed the first electron microscope. With the invention of the electron microscope, many infectious agents smaller than bacteria could be seen.

Until now, we can see how important the use of microscopes, especially in microbiology, that is the study of microorganisms.
