This image, sized for a science journal, shows one effect of chlorpyrifos on the human body, particularly in the nervous system. In the ‘normal’ scenario, the enzyme acetylcholinesterase (or cholinesterase) breaks down the neurotransmitter, acetylcholine. In the clinical scenario, the pesticide inhibits the enzyme from working properly, thus leading to an accumulation of acetylcholine. The build-up can cause over-stimulation of nerves, muscles, and glands.

This diagram shows the blood and nerve innervation of whale skin. The main area of focus is the dermal papilla, where the vessels from the dermis push the stratum basale up into the stratum granuloseum layer. The series of images along the bottom of the page demonstrate common patterns of innervation in the dermal papilla.
