Arginine vasotocin alters hamster pituitary LH and prolactin secretion in vitro
Abstract:
1. Arginine vasotocin (AVT) stimulated the release of both luteinizing hormone (LH) and prolactin (PRL) from normal hamster (Mesocricetus auratus) anterior pituitary glands in a dose-dependent manner. 2. AVT significantly augmented the depressed level of PRL release from pituitaries of blind-pinealectomized animals. 3. LH release from the pituitaries of blinded hamsters was inhibited by AVT while FSH levels were unaffected.

01:19Regulation of Hormone Secretion
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.

01:27Hormones of the Pituitary Gland
The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...
