Special Senses Review

Provide a brief explanation about: how do the senses of smell and taste function? Please start with the detection of stimuli by receptors and include the location and structure of receptors, and describe how they react to stimuli. Address how the signal is passed from receptors into the CNS....include pathway and the eventual location of cortex that is able to interpret the sensation, leading to perception. Please include a comparison between these two special senses. How are gustation and olfaction similar, and how are they different?

What are these conditions below? please provide brief description of the conditions. What anatomical feature or physiological process is affected that leads to perceivable signs or symptoms?

Olfaction: Deviated septum causing obstruction of flow of air

Gustation: Burning mouth syndrome

Explain the initiation and regulation of labor contraction including all organs and hormones (and hormone-like molecules) that participate in the process. Describe the positive feedback mechanism of labor contractions. Why do you think the slow intravenous injection of synthetic oxytocin (Pitocin®) can be used to induce parturition (childbirth)? After childbirth, pituitary-derived oxytocin also triggers milk ejection. What is the initial stimulus for the secretion of oxytocin? What is the target cell type of oxytocin in the mammary gland? For parturition, which layer of the uterus does this hormone act on?

  1. The total volume of air in Jeffrey’s lungs is 5800 mL. If his inspiratory capacity is 3200 and his residual volume is 1000, what is his ERV and FRC?

  1. TLC = 4200, VC = 3200, IC = 2000, What is the FRC and RV?

  1. VC = 3200, IC = 2200, ERV= 1000, RV = 1000, what is TLC?

The total volume of air Sally can inhale is 3400 mL after a quiet exhalation. When Sally is sitting still she breaths 400 mL and there’s 2200 mL of air leftover in her lungs. Calculate or figure out the following values: TV, TLC, IC, FRC, IRV

  1. When at rest, Jeremy inspires and expires 600 mL. While his lungs can fit 7000mL of air, only 5500 can move in and out, if he really really tries. Normally, there’s 3400 mL of air left in his lungs after a quiet exhalation. Calculate or figure out ERV, TV, TLC, IC, FRC, IRV, RV

(1) When engaged in involuntary breathing, which of the following volumes enter and/or exit the lungs? ERV, IRV, TV, VC. Which ones are always voluntary?
