Question
Chapter 15.3, Problem 28AYP
Summary Introduction
To analyze:
The pathway of the action potential from the rod or cone cell to the optic nerve.
Introduction:
After the absorption of light by the rhodopsin molecule, the shape of the opsin changes from 11-cis-retinal to all Trans retinal. This change leads to the activation of the attached g-protein known as transducin.

Draw a simple (typical of somatic senses) and a complex (typical of special senses) sensory neuron (receptor). Where applicable, label the cell body, the axon, the nerve endings, myelin, and the axon terminal.
Match the numbers in Figure with the description of what is happening as the sensory neurons, interneurons, and motor neurons communicate with one another. Start with number 1. ____ 1 Graded potential starts in a sensory receptor in the skin. ____ A t a second synapse, a graded potential followed by an action potential occurs in a secondary interneuron, which reaches the cerebral cortex. The graded potential triggers an action potential in a sensory neuron. ____ The lower motor neuron forms a neuromuscular synapse with the hand muscles, which causes the muscles to contract as he writes the letter. ____ In another synapse, the neurotransmitter creates a graded potential, which triggers an action potential in the lower motor neuron. ____ A primary interneuron forms an action potential and crosses to the opposite side of the brain. ____ A stimulus from the brain causes a graded potential and then an action potential to form in an upper motor neuron (which crosses back to the original side…
