Anatomy and physiology of the endocrine

ANP prevents aldosterone release, its goal being to reduce blood volume and blood pressure. A tropic hormone is a hormone that is able to trigger the release of another hormone in another gland.

If the level of adipose or leptin decreases below a certain threshold, the body enters starvation mode and attempts to conserve energy through increased hunger and food intake and decreased energy usage.

The activity of the pineal gland is inhibited by stimulation from the photoreceptors of the retina. Lipid-soluble hormones include the steroid hormones such as testosterone, estrogens, glucocorticoids, and mineralocorticoids.

Hormones of the Adrenal Medulla The adrenal medulla, like the posterior pituitary, develops from a knot of nervous tissue.

Endocrine Anatomy and Physiology

Hormone that stimulates milk production in females The posterior lobe produces the following hormones, which are not regulated by the hypothalamus: Exocrine organs direct the function of their target sites by releasing their active. This reaction may change a factor inside of the cell such as the permeability of the membrane or the activation of another molecule.

Within these islets are 2 types of cells—alpha and beta cells. Maturation of tissues, which appears in the development of adult features and adult behavior, are also determined by the endocrine system.

The parathyroid glands are mostly tiny masses of glandular tissue. Pituitary Gland The pituitary gland is approximately the size of a pea. There are two types of pancreatitis, acute and chronic. Adrenocorticotropic hormone ACTH stimulates the adrenal cortex, the outer part of the adrenal gland, to produce its hormones.

Uterine contractions and milk release. Human chorionic gonadotropin HCG assists progesterone by signaling the ovaries to maintain the production of estrogen and progesterone throughout pregnancy. Luteinizing hormone LH stimulates the gonads to produce the sex hormones—estrogens in females and testosterone in males.

Hormonal Regulation The levels of hormones in the body can be regulated by several factors. Mineralocorticoids, as their name suggests, are a group of hormones that help to regulate the concentration of mineral ions in the body.

The exocrine portion of the pancreas secretes digestive enzymes into the pancreatic duct. Hormones of the Posterior Pituitary The posterior pituitary is not an endocrine gland in the strict sense because it does not make the peptide hormones it releases, but it simply acts as a storage area for hormones made by hypothalamic neurons.

This light sensitivity causes melatonin to be produced only in low light or darkness. You’ll learn some general anatomy (a roadmap of your body), learn how the arm bone actually connects to the shoulder bone, and how the different organs work together to keep you alive.

Endocrine Anatomy and Physiology

Nervous System Function. The endocrine system works alongside of the nervous system to form the control systems of the body. The nervous system provides a very fast and narrowly targeted system to turn on specific glands and muscles throughout the body.

Endocrine glands: Endocrine organs, called glands, secrete hormones into the bloodstream. Hormones affect the activity of target sites that are often located far from the site of release.

Hormones affect the activity of target sites that are often located far from the site of release. The pancreas is a long, slender organ, most of which is located posterior to the bottom half of the stomach ().Although it is primarily an exocrine gland, secreting a variety of digestive enzymes, the pancreas has an endocrine function.

Its pancreatic islets—clusters of cells formerly known as the islets of Langerhans—secrete the hormones glucagon, insulin, somatostatin, and pancreatic.
