- Stimulus: Near vision or a close object.Receptor: Ciliary muscle and the lens.Afferent Limb: Optic nerve (cranial nerve II).Synapse(s): Optic nerve fibers synapse at the Edinger-Westphal nucleus in the midbrain.Efferent Limb: Preganglionic parasympathetic fibers from the Edinger-Westphal nucleusResponse: Constriction of the pupil (miosis) and adjustment of the lens curvature to focus on the near object.
- crucial neural pathway involved in the coordination of eye movements -MLF for conjugate eye movement (both eye in the same direction) - Eye mov't is always sent to the abducens CN 6
- A) Senses rotation or deceleration of head B) Receptors in semicircular canals C) Vestibular nuclei D) Oculomotor nuclei E) Extraocular muscles
- Location: optic chiasma Describe the outcome:Both of the temporal field visual fields are knocked (Lateral side)
- The Doppler effect is caused by a shift in __________ of moving particles, this is used in an _________
- Stimulus: Changes in light intensityReceptor: Retina of the eye, specifically the photoreceptors (rods and cones).Afferent Limb: Optic nerve (cranial nerve II)Synapse(s): Optic nerve fibers synapse at the pretectal nucleus in the midbrain.Efferent Limb: Preganglionic parasympathetic fibers from the Edinger-Westphal nucleus.Response: Constriction (miosis) or dilation (mydriasis) of the pupil to regulate the amount of light entering the eye
- Monitor breath sounds. • Report presence of crackles. • Discontinue infusion and notify provider of findings. • Monitor fetal heart rate for decreased variability

- If patient is too dizzy to use the restroom, a catheter may be needed
- crucial neural pathway involved in the coordination of eye movements, ensuring that the muscles responsible
- Location: R optic nerveDescribe the outcome: Temporal Field (on right side) Nasal Field (left side) Both Nasal and Temporal field of the Right Eye is affected resulting in ipsilateral eye (No vision)
- Monitor strict input and output, with urinary output hourly. • Report urine output of less than 25 to 30 mL/hr. • Output less than 25 mL/hr can warrant discontinuation of treatment
