Light - Posterior Lobe, Neurohypophysis
Dark - Anterior Lobe, Adenohypophysis
Identify the indicated structures.
AP: anterior pituitary
PP: posterior pituitary
P: pituitary stalk (infundibulum)
H: hypothalamus
V: ventricle
O: optic chiasm
What structure is this tissue from?
Pineal Gland. Recognize by the brain sand. (S)
What is this tissue from? Is it active?
Thyroid. Is active
What cells are shown around the colloid structure?
Inactive Follicular epithelial cells of the thyroid
What do the indicated cells secrete?
Calcitonin
These are parafollicular cells. Recognize them by small pale staining clusters.
Where are these tissue samples taken from?
Parathyroid. Recognize from the presence of adipocytes.
Identify the portions of this tissue. What is this gland?
