Receptor physiology
WebbThis course continues the systems-based approach to human anatomy and physiology at the organ, organ system, and organism level. Two major body systems related to regulation and integration of information will be explored in detail: the nervous and endocrine systems.

WebbAgonist binding to a receptor can be characterized both in terms of how much physiological response can be triggered (that is, the efficacy) and in terms of the concentration of the agonist that is required to produce the physiological response (often measured as EC 50, the concentration required to produce the half-maximal … Webb12 apr. 2024 · Orexins are a family of neuropeptides that regulate various physiological events, such as sleep/wakefulness as well as emotional and feeding behavior, and that act on two G-protein-coupled receptors, i.e., orexin 1 (OX1R) and orexin 2 receptors (OX2R). Since the discovery that dysfunction of the orexin/OX2R system causes the sleep …

In mice, deleting the GluN2B CTD is as harmful as knocking out the whole subunit, resulting in lethality (Mori et al .
WebbThere are four types of papillae, based on their appearance ( Figure 15.1.1 ): circumvallate, foliate, filiform, and fungiform. Within the structure of the papillae are taste buds that contain specialized gustatory receptor cells for the transduction of taste stimuli. These receptor cells are sensitive to the chemicals contained within foods ...
