What else can I help you with?
Is the pupillary light reflex autonomic and somatic?
Yes, the pupillary light reflex is mediated by both autonomic and somatic nervous systems. The autonomic nervous system controls the constriction of the pupil in response to light, while the somatic nervous system controls the movement of the muscles that dilate and constrict the pupil.
Name the division of autonomic nervous system responsible for pupillary light reflex?
The division of autonomic nervous system responsible for pupillary light reflex is the parasympathetic system. This is what causes the pupils to close down or open up in response to lighting conditions.
Is a patellar reflex autonomic?
no
Pupillary light reflex somatic or autonomic?
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.
What reflexes are classified as autonomic reflexes?
The ciliospinal reflex and the pupillary light reflex are classified as autonomic reflexes.
Is the pupillary light reflex sympathetic?
While pupillary size in principle is controlled both by the sympathetic and the parasympathic nervous system, the typical closure of the pupil after illumination (i.e. the pupillary light reflex) is mediated by the parasympathetic innervation of the constrictor muscle of the pupil.
What is the control center of micturation reflex?
central.somatic and autonomic nervous systems
What division of the autonomic nervous system mediates the reflex release of saliva?
The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients.

Is a effector are skeletal muscles a somatic reflex or a autonomic reflex?
Skeletal muscles, which are effectors, are involved in somatic reflexes. Somatic reflexes involve voluntary control of skeletal muscles and are part of the somatic nervous system. Autonomic reflexes, on the other hand, involve the control of smooth muscle, cardiac muscle, and glands, and are part of the autonomic nervous system.
How does the patella reflex differ from the pupillary reflex?
The patellar reflex involves the tapping of the patellar tendon to elicit a knee jerk response, testing the integrity of the spinal nerves. The pupillary reflex involves the constriction of the pupils in response to bright light, mediated by the autonomic nervous system. Both reflexes are protective mechanisms but involve different anatomical pathways.
What type of reflexes are not subject to conscious control?
Involuntary reflexes, such as the knee-jerk reflex or pupillary reflex, are not subject to conscious control. These automatic responses are typically controlled by the spinal cord or brainstem without involvement of higher brain regions.
Light shown into the eye will result in a decrease of the papillary diameter which nerves are involved in this reflex?
The autonomic nervous system is responsible for controlling the pupillary reflex. The parasympathetic nerves, specifically the oculomotor nerve (cranial nerve III), cause constriction of the pupils in response to light.
