OpenStax AnatPhys fig.15.9 - Autonomic Control of Pupil Size - English labels

nid: 58811
Additional formats:
None available
Description:
Autonomic Control of Pupillary Size Activation of the pupillary reflex comes from the amount of light activating the retinal ganglion cells, as sent along the optic nerve. The output of the sympathetic system projects through the superior cervical ganglion, where as the parasympathetic system originates out of the midbrain and projects through the oculomotor nerve to the ciliary ganglion, which then projects to the iris. The postganglionic fibers of either division release neurotransmitters onto the smooth muscles of the iris to cause changes in the pupillary size. Norepinephrine results in dilation and ACh results in constriction. English labels. From OpenStax book 'Anatomy and Physiology', fig. 15.9.
