Across
- 4. Specialized glial-like cells lining the third ventricle, near the median eminence, that regulate molecular exchange between blood, CSF, and the hypothalamus.
- 6. Iodine-containing thyroid hormone (T3) that plays a crucial role in metabolism and development.
- 8. Cellular process that moves molecules across endothelial barriers via vesicular transport.
- 9. Small brain structure that secretes melatonin and regulates circadian timing.
- 10. Specialized cells in the nervous system that synthesize and release hormones directly into the bloodstream.
- 13. Circulating inactive hormone precursor that must be converted into its active form in peripheral tissues.
- 14. DNA regulatory sequence that allows hormone-receptor complexes to modulate gene transcription, hormone response ________.
- 15. Releasing and inhibiting hormones secreted by the neurosecretory cells of the hypothalamus make their way to the anterior pituitary via the _____ portal system.
Down
- 1. Cells embedded in the brain capillary basement membrane that regulate blood–brain barrier stability and permeability.
- 2. Temporary adaptive shift away from normal physiological set points during stress or threat.
- 3. Referring to the nervous system division that independently regulates gastrointestinal function.
- 5. Specialized brain regions or organs lacking a typical blood–brain barrier that detect circulating signals and regulate homeostasis.
- 7. Sensory process that monitors internal bodily states such as temperature, osmolarity, and energy balance.
- 11. A hormone released by the posterior pituitary that enables maternal behavior.
- 12. Glial cells whose endfeet contribute structurally and functionally to the blood–brain barrier.
