Ach decreases the heart rate and the force of the contraction. This is done through signaling molecules, and how they have a different effect on the heart vs salivary glands is that they have different receptors but sometimes they have the same receptor just the internal machinery is different.

What is the period of time called between the beginning of one heartbeat and the start of the next?
Cardiac cycle
The two neurotransmitters that affect smooth muscle cells are acetylcholine and?
noradrenaline
Which phase of the cardiac cycle is longest?
ventricular diastole
What is the relaxing phase of the cardiac cycle?
The resting phace of the cardiac cycle is known as the refractory period
Is acetylcholine stimulatory to cardiac muscle?
False
What excites skeletal muscles and inhibits cardiac muscle?
Acetylcholine
What is one complete heartbeat called?
The cardiac cycle.
What chemical is likely to be released when the cardiac centers detect an abundance of oxygen in the blood?
acetylcholine
What is the importance of cardiac cycle?
The importance of cardiac cycle is to sustain human life.
All of these neurons release acetylcholine as a neurotransmitter except?
specific cardiac and smooth muscle fibers
What can acetylcholine and norepinephrine affect?
Smooth Muscle Cells
Which muscle contraction does acetylcholine and norepinephrine affect?
Acetylcholine and norepinephrine both affect smooth muscle contraction. They stimulate contraction in some muscles and inhibits contraction in others.
What is the period of time called between the beginning of one heartbeat and the start of the next?
Cardiac cycle
How does acetylcholine affect a black widow spider bite?
Learning!
What is a complete cycle of a heart contraction and relaxation called?
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
The two neurotransmitters that affect smooth muscle cells are acetylcholine and?
noradrenaline
