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.

Which of these events is caused by the stapes pushing against membrane covering the oval window?A The pressure change causes the
Nezavi [6.7K]

Answer:

The correct answer is option C "The pressure change causes the organ of Corti to vibrate vertically".

Explanation:

The organ of Corti is an important structure for auditory perception that acts as a receptor organ for hearing.  The organ of Corti is located in the mammalian cochlea and it allows for the transduction of auditory signals into nerve impulses according to the vibrations that are received from external sources. If the receiving sounds comes from the stapes pushing against membrane covering the oval window, the pressure change will causes the organ of Corti to vibrate vertically. Stimulus from membrane covering the oval window are sent to the organ of Corti, which responds by vibrating vertically.
