autonomic reflex
The receptor is the retina of the eye; smooth muscle of the iris is the effector. They both change simultaneously because the pupillary light reflex is contralateral.
true
vasomotor center
This particular reflex is autonomic as the affected muscle, constrictor pupillae muscle, is a smooth muscle and not under conscious control. Typically if you can consciously contract the muscle, any reflex associated with that muscle is somatic in nature.
somatic nervous system
Smooth muscle activity is responsible for involuntary body activities and the contractility of hollow organs. Hollow organs include the bladder gastrointestinal tract blood vessels, and the uterus.
autonomic
segmentation
The somatic nervous system regulates skeletal muscle tissue, while the ANS services smooth muscle, cardiac muscle, and glandular tissue.
They are controlled by the autonomic nervous system.
A smooth muscle is responsible for the contractibility of hollow organs, such as blood vessels and the gastrointestinal tract. Going to the bathroom would be controlled by these types of muscles.
