- ______ is another hormone released from the thyroid gland
-> is causes more calcium reabsorption in the bo____
- The _____ cells in the thyroid gland perform all of the functions
required for thyroid hormone synthesis.
- _____ is transported from the circulation into the inner core along
with the protein thyroglobulin, which is synthesized within the cells. -
Follicles also produce a ____ ____ enzyme and secrete it on the apical
surface next to the colloid.
,- Thyroid peroxidase activates and attaches io____ to ty___ ____ in the
thyroglobulin.
- Two io_____ are then coupled together, but remain attached to
thyroglobulin.
- Simulation by TS____ initiates a cascade that induces the follicle cell to
endocytose some of the colloid, followed by combining it with a
