Nervous system is controlling the actions of the body. Neurotransmitters are the chemicals released in the nervous system that pass information in the form of signals from one neuron to other and ultimately to the brain. Norepinephrine is a neurotransmitter.

Question

The endocrine system regulates cardiac output through chronotropic and inotropic hormones and through hormones that regulate water balance .c. The parasympathetic nervous system releases acetylcholine,which is a strongly negative inotropic agent. d. Factors such as electrolyte concentrations, body temperature,and age all affect cardiac output.

Which one of the following statements about gap junctions or electrical synapses is incorrect? A. Abundant gap junctions between cardiac muscle cells allow coordinated waves of contraction to spread through the heart muscle. B. Synaptic delays at electrical synapses are shorter than synaptic delays at chemical synapses. C. Gap junctions at electrical synapses are formed from proteins made in both the presynaptic and postsynaptic cells. D. Electrical synapses can be either excitatory or inhibitory. E. Electrical synapses are inherently bidirectional, i.e., current can spread between two coupled cells in either direction Please give me the correct answer quickly I will give you upvote
