autonomic nervous system.
The pupillary light reflex is an autonomic response controlled by the parasympathetic and sympathetic branches of the autonomic nervous system. When light is detected by the retina, signals are sent to the brainstem to constrict the pupil (parasympathetic activation) or dilate the pupil (sympathetic activation) depending on the intensity of the light.
Skeletal muscle is not directly controlled by the autonomic nervous system. Skeletal muscles are under voluntary control, with motor neurons from the somatic nervous system providing the neural input for their activation. Autonomic nervous system controls smooth muscle, cardiac muscle, and glands.

Dilation of the bronchial tubes is increased by the sympathetic nervous system. Specifically, the release of norepinephrine from sympathetic nerve endings causes relaxation of the smooth muscle in the bronchial tubes, leading to bronchodilation.
The autonomic nervous system is a division of the peripheral nervous system that controls automatic responses in the body, such as the heart rate, hormone levels, gastrointestinal functions, and metabolism.
Activation of the sympathetic division of the autonomic nervous system during stress can lead to symptoms such as increased heart rate, elevated blood pressure, pupil dilation, dilated airways, increased sweating, and decreased digestion. These physiological responses help prepare the body for the "fight or flight" response to perceived threats.
The autonomic nervous system that controls the functions within the body. Some functions that it controls are the heartbeat, digestive system, and breathing. The autonomic nervous system is the part of the peripheral nervous system that acts as a control system. It functions largely below the level of consciousness to control visceral functions.
The autonomic nervous system.
Yes, the autonomic nervous system can cause either activation or inhibition depending on whether the sympathetic division or parasympathetic division is active, and which target organ is being affected. The sympathetic division generally activates the fight-or-flight response while the parasympathetic division promotes rest and relaxation.
