Figure 392 The Endocrine Glands
Section 39-1
Pineal gland The pineal gland releases melatonin,
which is involved in rhythmic activities, such as
daily sleep-wake cycles.
Hypothalamus The hypothalamus makes hormones that
control the pituitary gland. In addition, it
makes hormones that are stored in the pituitary
gland.
Thyroid The thyroid produces thyroxine, which
regulates metabolism.
Pituitary gland The pituitary gland produces
hormones that regulate many of the other
endocrine glands.
Pancreas The pancreas produces insulin and
glucagon, which regulate the level of glucose in
the blood.
Parathyroid glands These four glands release
parathyroid hormone, which regulate the level of
calcium in the blood.
Ovary The ovaries produce estrogen and
progesterone. Estrogen is required for the
development of secondary sex characteristics and
for the development of eggs. Progesterone
prepares the uterus for a fertilized egg.
Thymus During childhood, the thymus releases
thymosin, which stimulates Tcell development.
Testis The testes produce testosterone, which is
responsible for sperm production and the
development of male secondary sex characteristics
Adrenal glands The adrenal glands release
epinephrine and nonepinephrine, which help the
body deal with stress.
