431 Lab Practical 3 Review Exam #Questions with correct
answers
Endocrine system - ✔✔System of ductless glands that secrete hormones into the
bloodstream to regulate body functions.
Hypothalamus - ✔✔Controls the endocrine system by releasing hormones that
regulate the pituitary gland.
Infundibulum - ✔✔Stalk connecting the hypothalamus to the pituitary gland.
Pituitary gland - ✔✔Major endocrine gland that controls growth, metabolism,
reproduction, and other endocrine glands.
Anterior pituitary - ✔✔Glandular lobe that secretes GH, TSH, ACTH, LH, FSH, and
prolactin.
Posterior pituitary - ✔✔Stores/releases ADH and oxytocin produced by the
hypothalamus.
Pineal gland - ✔✔Produces melatonin to regulate circadian rhythms.
Thyroid gland - ✔✔Produces T3 and T4 to regulate metabolism, and calcitonin for
calcium balance.
Thyroid lobe - ✔✔One side of the butterfly-shaped thyroid gland.
, Isthmus (thyroid) - ✔✔Narrow bridge connecting the right and left thyroid lobes.
Parathyroid glands - ✔✔Four small glands producing PTH to raise blood calcium.
Thymus - ✔✔Endocrine and immune organ producing thymosins for T-cell
maturation (larger in children).
Adrenal glands - ✔✔Paired glands above kidneys producing steroid hormones and
catecholamines.
Adrenal cortex - ✔✔Outer adrenal layer producing aldosterone, cortisol, and
androgens.
Adrenal medulla - ✔✔Inner adrenal region producing epinephrine and
norepinephrine.
Kidneys (endocrine role) - ✔✔Produce EPO and renin; contribute to blood
pressure and RBC regulation.
Pancreas - ✔✔Organ with endocrine (insulin, glucagon, somatostatin) and
exocrine digestive functions.
Islets of Langerhans - ✔✔Endocrine clusters in pancreas producing insulin,
glucagon, and somatostatin.
