No, a planet does not collapse because gravity isn't strong enough to provide enough pressure to crush a planet. You might make a planet heavier and heavier as to increase its gravity but at some point the pressure in the planet's core will be high enough to support nuclear fusion and the planet will have changed into a star. At that point radiative pressure also begins to fight gravity.
Examples include the acceleration of the heartbeat, raising of blood pressure, shrinkage of the pupils of the eyes, and the redirection of blood away from the skin to muscles, brain, and the heart.
The sympathetic division causes increases in blood levels to prepare the body to cope with external pressure/ situations (danger, excitement). It is also known as the fight or flight subdivision.
