A student is in a car accident, and although not hurt, immediately experiences pupil dilation, increased heart rate, and rapid breathing. What type of endocrine system stimulus did the student receive?

The student received endocrine system neural stimulus.

Explanation:

The endocrine system consists of glands that are responsible for hormones production. The hormones regulate metabolism, growth and development and tissue function. A neural stimulus is one such hormone released by the glands of the endocrine system. The neural stimuli are released by the stimulation of endocrine system.

The neural stimuli may cause pupil dilation, sudden increase in heart rate and rapid breathing. The hormonal release can be stimulated by the nerve fibers.
