Anatomy and Physiology of Special Sensory Organs

Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neu…

Sensory Receptors

The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory rece…

4. This question focuses on entrainment. a. What is entrainment? b. What environmental cues are involved in entrainment, and which one is most influential? c. Why is entrainment necessary? d. Assuming that a flash of darkness is an effective zeitgeber, what impact on circadian rhythms would you expect to result from an event such as the 2024 solar eclipse (assume it was viewed from Carbondale IL, where totality occurred at about 2 pm)? Explain your reasoning. You may wish to consult this phase response diagram. Phase Shift (Hours) Delay Zone Advance Zone Dawn Mid-day Dusk Night Dawn Time of Light Stimulus e. Finally, give a real-world example of how knowledge of circadian rhythms and entrainment has implications for human health and wellbeing or conservation biology. This example could be from your reading or from things discussed in class.
