Summary Introduction

Introduction:

Temperature is detected by thermoreceptors in the form of cold or heat. The nociceptors are pain receptors present in the skin and certain internal organs of body. The pain receptors receive signals from damaged skin and transmit those signals to the brain. They are non-adaptive, that is, a person cannot bear extreme pain for a very long period of time. Analgesics are used to cure pain temporarily.

In which of these ways do coldness receptors differ from heat receptors?A. Coldness receptors respond to a change in temperature, not to the absolute temperature.B. The response of a coldness receptor grows stronger and stronger until you find a warmer place.C. Coldness receptors also respond to certain chemicals, whereas heat receptors do not.D. Coldness receptors respond only to life-threatening levels of cold
Which of the following statements about the intensity of a nerve response is true? Select one: a. A stimulus reaching the threshold level may or may not propagate a nerve impulse. b. A small voltage shift and a large voltage shift will yield the same nerve impulse as long as the stimulus reaches the threshold level. c. All stimuli, regardless of the strength, will always generate a nerve impulse. d. A stimulus resulting in a greater voltage shift will result in a stronger nerve impulse and increased sense of perception in the brain.
A patient presents with the chief complaint of being unable to perceive “saltiness,” but they can perceive other flavors. From the image below, you propose the following pathway changes for sour perceptions as an explanation for these symptoms: A. The channels for Na+ were damaged B. Voltage-gated Ca2+ channels are not functioning C. There is no neurotransmitter release D. The afferent nerve is damaged E. All the above are viable pathway changes that would uniquely prevent the perception of salty
