Summary Introduction

To explain: How melanocyte-stimulating hormone (MSH) enables skin color change and distribution in frog based on its surrounding and how neuroendocrine signals activate MSH.

Concept introduction:

In neuroendocrine pathway, sensory neurons stimulate neurosecretory cells to release neurohormones. Like endocrine hormones, neurohormones reach their target receptors via the bloodstream. MSH is a peptide hormone produced by skin, pituitary and hypothalamus. It stimulates melanocytes to produce melanin pigment.
