Answer #1

Sympathetic innervation of the heart arises from the ________ segments of the spinal cord.

Answer:-T1-T5

Explanation:- Sympathetic innervation is responsible for increasing heart rate, increasing force of heart beat, and dilating coronary arteries. These preganglionic sympathetic neuron cell bodies are located in the lateral horns of spinal cord segments T1-T5. The cardiac nerves are controlled by cells T1-T5 segment of the spinal cordThus heart receives sympathetic innervation from T1-T5 segments of the spinal cord.
