The sympathetic nervous system releases hormones known as catecholamines which increase the heart rate.
<h3>What is a heart rate? </h3>
it is the number of contractions of the heart per minute.
<h3>What are catecholamines?</h3>
These are the neurotransmitters that have a catechol and a side chain that is an amine.
<h3>Which catecholamines are released by the sympathetic nervous system?</h3>
Epinephrine and norepinephrine are the catecholamines that are released by the sympathetic nervous system to increase the heart rate.
<h3>Where are these hormones released?</h3>
These hormones are released in the blood.
<h3>How does this hormone increase the heart rate?</h3>
- "These hormones are released at the neuromuscular junction of the cardiac nerves."
- "They shorten the repolarization period."
- This speeds up the rate of depolarization and contraction and thus the heart rate is increased.
