The pars intermedia of the pituitary gland is poorly developed in human beings, but in fish it secretes ____.
Options:
Answer:
C
Solution:
The pars intermedia of the pituitary gland secretes Melanocyte Stimulating Hormone (MSH).
In lower vertebrates such as fish, amphibians, and reptiles, the pars intermedia is well developed and the MSH secreted by it regulates skin pigmentation by stimulating the dispersion of melanin granules in melanocytes.
In humans, the pars intermedia is almost merged with the pars distalis.
FSH and TSH are secreted by the pars distalis (anterior pituitary), while PTH is secreted by the parathyroid gland.
