To discuss:
The location of hormone receptors in the target cells and differences between hydrophilic and hydrophobic hormone receptor systems.
Introduction:
Hormones are chemical messengers secreted by the endocrine glands or neurosecretory cells into the extracellular fluids. The secreted hormones reach the target cells through the bloodstream, and they stimulate response of other tissues or cells. Hormones bind only to specific cells based on their corresponding receptors present on the cells. Hormones act through chemical signals. They regulate growth, development, blood pressure,

- How the activities of endocrine glands are regulatedarrow_forwardUnlike the glucocorticoid receptor, the thyroid receptor has an activity even in the absence of thyroid hormone. Explain the activity of the receptor under these conditions and how hormone binding changes the activity.arrow_forwardSteroid hormones find their receptors inside of cells. True or Flase? This is true. Explain why this is not falsearrow_forward
- N-methyl-aspartate (NMDA) receptor is activated by glutamate and is ligand-gated calcium ion channel. True or Falsearrow_forwardEndocrinology Because they are relatively hydrophobic, peptide hormones can interact with both cytoplasmic and nuclear receptors, depending on the specific hormone. Rather than being stored in intracellular vesicles, catecholamine hormones are synthesized on demand and released immediately upon being synthesized. Although vasopressin is synthesized in the hypothalamus, it is released from the terminals of neurons located in the posterior pituitary.arrow_forwardTwo substances regulated by parathyroid hormone.arrow_forward
