Why does follicular atresia occur more frequently in smaller ovarian follicles during the luteal phase?

💡 Explanation

Follicular atresia, the degeneration of ovarian follicles, occurs because smaller follicles have fewer LH receptors, therefore they are less responsive to the low LH levels present during the luteal phase, rather than high FSH rescuing them. Consequently, they undergo apoptosis.

• If a patient with a non-functional filaggrin gene (involved in keratinocyte aggregation) sustains a deep dermal abrasion, which consequence regarding healing is most likely?
• If a patient's thyroid hormone levels remain low despite increased TSH secretion, which mechanism explains this persistent hypothyroidism?
• A patient with hypertension has increased arterial stiffness and reduced baroreceptor sensitivity. If the RAAS system is chronically overactive, which outcome is most likely?
