Sympathetic/parasympathetic nerve fibres decrease rate of heart beat.

Blood pressure increases and heart rate decreases in response to

Sympathetic nerve fibres ___________the heart rate while parasympathetic nerve fibres _____________the heart rate.

[A]: In vertebrates, motor fibres to striped muscle, parasympathetic fibres to smooth muscle, and preganglionic sympathetic fibres are cholinergic. [R]: Cholinergic designates the type of nerve fibre that releases acetylcholine from its ending when stimulated by a nerve impulse
