Phasic receptor. A phasic receptor is a sensory receptor that returns to its resting potential even though the stimulus is still applied. The process by which the magnitude of the generator potential decreases, even when the stimulus is maintained, is called adaptation. 1  Pacinian corpuscles. 2  Tonic receptor. 3  Phasic transmitter.
The normal resting adult heart beats regularly at an average rate of 60-100 times per minute. How fast the heart beats (heart rate) is governed by the speed of electrical signals originating from the pacemaker of the heart, the SA node.
A normal resting heart rate for adults ranges from 60 to 100 beats per minute (bpm), according to The Mayo Clinic. Women tend to have a slightly higher heart rate than men; the average resting heart rate in women is in the mid-70s, while it is only about 70 in men. normal resting heart rate for adults ranges from 60 to 100 beats per minute (bpm), according to The Mayo Clinic.
