The sympathetic nervous system is a part of the autonomic nervous system that carries stress responses or "flight or flight" responses that involves feelings of rush. The activation of sympathetic nervous system therefore increases the heart rate. The parasympathetic nervous system is another part of the autonomic nervous system which is responsible for "rest and digest" responses that involves feelings of relaxation. The activation of the parasympathetic nervous system decreases the heart rate.

Answer:
The correct answer will be- Transmission electron microscope
Explanation:
A Microscope is an optical instrument designed to view the microscopic things which could be living or non-living around us.
The internal structure of a microscope can be viewed by a light microscope mainly dark-field microscope but a detailed structure of a microscope can be viewed by an electron microscope mainly a transmission electron microscope.
The transmission electron microscope studies the internals structure of the cell by creating the 2D images by passing the beam of electrons through the specimen.
Thus, a transmission electron microscope is the correct answer.
