Expert Solution & Answer

Summary Introduction

To determine: The reason why it makes sense to classify nociceptors as a distinct class of sensory receptors.

Introduction:

Nociceptors are the sensory receptors that respond to threat stimuli. They are also called pain receptors because they sense any threat to the body and then alarm the brain and spinal cord. They are free nerve endings of a sensory neuron, and they are found in every tissue. When the electric current generated by the neurons reaches above the threshold value, nociceptors get activated and send signals to the central nervous system.

Explanation of Solution

In response to any kind of threat or pain, sensory neurons transmit the signals to interneurons in the spinal cord for the integration of these signals. Substance P is the neurotransmitter that stimulates the interneurons, which carry the signals to the spinal cord. The spinal cord then sends the signals to the brain and the thalamus and the perception of the pain starts. The nociceptors are similar with the other classes of receptors by the kind of stimulus they recognize but are different from the other classes of receptors in the way they recognize the stimulus. Hence, it creates a sense to “eliminate nociceptors as a distinct class of receptors”.

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
