Summary Introduction

To determine: The conclusion that can be drawn regarding the efferent and afferent path of the eye when constriction of pupil occurs only in the right eye if the light is shone to the left eye.

Introduction: The afferent neurons are the sensory neurons which carry the impulses or signals from the stimuli to the central nervous system. The efferent neurons are the motors neuron which carries the signals from the central nervous system to the muscles to cause a movement.

Applying a pressure stimulus to the fluid-filled capsule of an isolated Pacinian corpuscle causes a brief burst of action potentials in the afferent neuron, which ceases until the pressure is removed, at which time another brief burst of action potentials occurs. If an experimenter removes the capsule and applies pressure directly to the afferent neuron ending, action potentials are continuously fired during the stimulus. Explain these results in the context ofadaptation.

Which of the following is the correct sequence of the neural chain of events set in motion by an environmental stimulus? (A) Receptors, afferent neurons, interneurons, efferent neurons, effectors (B) Receptors, efferent neurons, interneurons, afferent neurons, effectors (C) Interneurons, effectors, receptors, afferent neurons, efferent neurons (D) Effectors, interneurons, receptors, afferent neurons, efferent neurons (E) Effectors, receptors, afferent neurons, effer- ent neurons, interneurons

When light strikes a photoreceptor, it reduces the amount of glutamate that it releases. This releases ___ cells from inhibition, allowing them to release more neurotransmitters and excite ___ cells. This produces action potentials that travel down the optic nerve. A) horizontal; amacrine B) amacrine; horizontal C) ganglion; bipolar D) bipolar; ganglion
