Step-by-step solution
It contains several groups of neurosecretory cells called nuclei which produce hormones. Each thyroid follicle is composed of follicular cells, enclosing a cavity. These follicular cells synthesise two hormones, tetraiodothyronine or thyroxine (T4) and triiodothyronine (T3).The α-cells secrete a hormone called glucagon, while the β-cells secrete insulin. The Leydig cells or interstitial cells, which are present in the intertubular spaces produce a group of hormones called androgens mainly testosterone.
