Question

Specifically describe the anatomical neurological structures and mechanisms responsible for your resting heart rate and your increased heart rate during moderate exercise, and your decreased heart rate during recovery.

Answer 1

The heart rate is maintained by the

1. Vasomotor centre
2. The motor nerve fibers if our human Heart
3. The specific sensory nerve fiber from Heart

1 )Vasomotorarea has 3 areas that is

1. Vasoconstrictor area that cause sympathetic nervous impulses and increase the heart rate in exercise as well as maintain heart rate
2. Vasodilation area -. This area in brain cause vagus nerve stimulation and Decrease heart rate if high
3. In Exersice the sensory area will receive the signal from the Baroreceptor and there by the stimulation of vasoconstrictor or vasodilator are will take place.

2 )Themotor nerve fibers are

At rest heart rate is an effect of the mixture of the parasympathetic and sympathetic nervous system

The parasympathetic has cardioinhibitory effect and sympathetic have cardiostimulatory effect

3)Sensory nerve fibers from heart that carry the stretch and pain from heart to brain and cause motor effects .
