Answer 3

not sufficient for determining gender

people with XY chromosomes can have female anatomy

Answer 4

… Endocrine (hormone) systems via effect on adjacent Pituitary Gland (the “Master Gland”)

Question 5

Answer 5

…flow via blood vessels to Anterior Pituitary stimulating gland to release its own hormones

Answer 6

(e.g. Oxytocin)

sent (like NTs) via axons to Posterior Pituitary, then circulate in bloodstream
