Question

The hormonal action in the posterior pituitary is triggered by

• A. Hypophysial tract
• B. Neurosecretory cells
• C. Podocytes cells
• D. None of the above

Answer 1

The correct option is B Neurosecretory cells

• Neurosecretion is the storage, synthesis and release of hormones from neurons.
• These neurohormones, produced by neurosecretory cells, are normally secreted from nerve cells in the brain that then circulate into the blood.
• The posterior pituitary gland does not produce hormones, but rather stores and secretes hormones produced by the hypothalamus. Hence, The hormonal action in the posterior pituitary is triggered by Neurosecretory cells.
So, the correct answer is 'Neurosecretory cells'.
