Thyrotropin-releasing hormone (TRH) produced in the parvocellular division of the hypothalamus is the key peptide hormone responsible for HPT regulation.

Growth hormone is a protein hormone of about 190 amino acids that is synthesized and secreted by cells called somatotrophs in the anterior pituitary.

How do the nervous and endocrine systems differ in their rate of their control and in the way in which they communicate? The endocrine system uses hormones while the nervous system uses electrical impulses. The endocrine system controls metabolism, growth, sleep cycles and other metabolic processes using hormones.

Luteinizing Hormone Releasing Hormone (LHRH)or Gonadotropin Releasing Hormone (GnRH)is a key molecule in the regulation of reproduction in vertebrates. LHRH, a decapeptide, is produced by neurons in the medial basal hypothalamus (MBH) and secreted in a pulsatile manner into the cardiovascular system.

The pituitary gland is in the brain below the hypothalamus. It secretes hormones in response to chemical messages from the hypothalamus. The human growth hormone (HGH) helps to influence height, as well as build bones and muscles in the body. It is crucial for processes involved in normal human growth and development.
272909
The posterior pituitary gland does not produce hormones, but rather stores and secretes hormones produced by the hypothalamus. The paraventricular nuclei produce the hormone oxytocin, whereas the supraoptic nuclei produce ADH.
917673
Both the PVN and the supraoptic nucleus do produce small amounts of the other hormone, ADH and Oxytocin respectively. Other PVN neurons control various anterior pituitary functions, while still others directly regulate appetite and autonomic functions in the brainstem and spinal cord.

Neurotransmitters: Neurotransmitters are proteins, amino acids or gases. Hormones: Hormones are produced in endocrine glands and are secreted into the blood stream. Neurotransmitters: Neurotransmitters are released by presynaptic nerve terminal into the synapse. Hormones: Hormones are transmitted through blood.

One of the significant difference between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.
364917
Growth hormone-releasing hormone is a hormone produced in the hypothalamus. The main role of growth hormone-releasing hormone is to stimulate the pituitary gland to produce and release growth hormone into the bloodstream. This then acts on virtually every tissue of the body to control metabolism and growth.
1024816
Brain natriuretic peptide (BNP) is a cardiac neurohormone secreted from ventricular myocytes in response to increased end-diastolic pressure or volume. Accumulating evidence showed that BNP concentrations are increased in heart failure, and it is especially important in the differential diagnosis of dyspnea.
1430179
norepinephrine. Norepinephrine represents a stress hormone.
174862
The portion of the brain that maintains the body's internal balance (homeostasis). The hypothalamus is the link between the endocrine and nervous systems. The hypothalamus produces releasing and inhibiting hormones, which stop and start the production of other hormones throughout the body.
1250675
A hormone is a chemical (specifically a protein) secreted by an endocrine gland (gland is just a. name for an organ that secretes something) that. signals a system to do something.
742037
Vasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to the posterior pituitary, which releases it into the blood. AVP has two principle sites of action: the kidney and blood vessels.

The endocrine system consists of cells, tissues, and organs that secrete hormones critical to homeostasis. The body coordinates its functions through two major types of communication: neural and endocrine. Neural communication includes both electrical and chemical signaling between neurons and target cells.
