Trace the sequence of events followed by the exposure to prolonged stress:

A. Glucocorticoids are released by adrenal cortex

B. Lymphocytes are activated

C. Hippocampal cells get degenerated

D. Anterior pituitary releases ACTH

Show answer & explanation

Correct answer: C. D, A, B, E, C

Explanation

Prolonged stress: ACTH from the anterior pituitary → glucocorticoids from the adrenal cortex → lymphocyte activity is altered → T- and B-cell changes → hippocampal neurons degenerate (as keyed).
