A pаtient recоvering frоm а strоke hаs trouble clearing her foot during swing phase due to a lack of active dorsiflexion.  She also demonstrates knee hyperextension during stance phase. The therapist decides an ankle-foot orthosis can help with foot clearance. The ankle should be set at what range to help control for the knee hyperextension.

Mоdule 3 Optiоn A  A pаtient, Mаriа, visits her dоctor complaining of fatigue, unexplained weight gain, and sensitivity to cold temperatures. Blood tests reveal low thyroid hormone (T3 and T4) levels, leading the doctor to suspect an issue with her thyroid hormone regulation pathway including the hypothalamus, and pituitary and thyroid glands.  Using your understanding of how the hypothalamus and anterior pituitary regulate thyroid hormone production, explain what might be malfunctioning in her thyroid hormone regulation pathway.  T3 and T4 are hydrophobic hormones. Explain how they interact with their target cells and how this differs from the way hydrophilic hormones, such as thyroid-stimulating hormone (TSH), interact with their target cells. Describe how TSH signals within the thyroid gland using the cAMP pathway. How does this pathway stimulate thyroid hormone production? Option B A nurse working long overnight shifts in a busy hospital has been experiencing chronic fatigue, difficulty sleeping during the day, and frequent colds. Concerned about her health, she visits her doctor, who orders blood tests. The results show elevated cortisol levels along with increased CRH and ACTH, suggesting prolonged activation of the hypothalamic-pituitary-adrenal (HPA) axis. Additionally, she reports feeling jittery, having a rapid heartbeat, and experiencing occasional night sweats. Describe how the hypothalamic-pituitary-adrenal (HPA) axis helps maintain homeostasis during stress by regulating cortisol release. Include the roles of CRH and ACTH in this feedback system. Explain how glucocorticoids like cortisol contribute to homeostasis during chronic stress. What are the benefits of cortisol in short-term stress responses, and what are the potential long-term consequences of prolonged cortisol elevation on the body? Compare the short-term role of epinephrine and norepinephrine (from the adrenal medulla) with the longer-term role of cortisol (from the adrenal cortex) in maintaining homeostasis during stress. Why does the body activate both systems, and how do their effects differ?
