E)Purkinje cell

Quizplus · Accepted Answer

The diagram labeled C depicts a Pacinian corpuscle, which is a type of unipolar neuron found in the skin that responds to mechanical pressure and vibration. Merkel discs (A) are another type of unipolar neuron that respond to pressure and touch, but they are not depicted in the diagram. Meissner corpuscles (B) are also a type of unipolar neuron that respond to touch and low-frequency vibration, but they are characterized by flattened cells around the dendrites, which are not evident in the diagram. Nociceptors (D) are a type of sensory receptor that respond to painful stimuli, but they are not shown in the diagram. Purkinje cells (E) are a type of multipolar neuron found in the cerebellum that play a role in coordinating movement, but they are not depicted in the diagram.
