- Paling or flushing, or alternating between both
- Inhibition of stomach and upper-intestinal action to the point where digestion slows down or stops
- General effect on the sphincters of the body
- Constriction of blood vessels in many parts of the body
- Liberation of metabolic energy sources (particularly fat and glycogen) for muscular action
- Dilation of blood vessels for muscles
- Inhibition of the lacrimal gland (responsible for tear production) and salivation
- Dilation of pupil (mydriasis)
- Relaxation of bladder
- Inhibition of erection
- Loss of hearing
- Tunnel vision (loss of peripheral vision)
- Disinhibition of spinal reflexes
- Tremors
- Increased muscle tension in order to provide the body with extra speed and strength.
