Functional anatomy of the endocrine glands

Luteinizing hormone LH stimulates the gonads to produce the sex hormones—estrogens in females and testosterone in males. The alpha cells produce the hormone glucagon, which is responsible for raising blood glucose levels.

Endocrine System

Many hormones produced by the endocrine system are classified as tropic hormones. Testosterone has effects on many parts of the body, including the muscles, bones, sex organs, and hair follicles. The other part of the pancreas, the endocrine pancreas, secretes hormones called insulin and glucagon.

Pancreatitis simply means inflammation of the pancreas. Hormones are distributed by glands through the bloodstream to the entire body, affecting any cell with a receptor for a particular hormone.

Calcitonin functions to reduce the concentration of calcium ions in the blood by aiding the absorption of calcium into the matrix of bones.

This hormone causes growth and increases in strength of the bones and muscles, including the accelerated growth of long bones during adolescence.

Prolactin PRL has many effects on the body, chief of which is that it stimulates the mammary glands of the breast to produce milk. Thyroid stimulating hormone TSHas its name suggests, is a tropic hormone responsible for the stimulation of the thyroid gland.

The function of the anterior pituitary gland is controlled by the releasing and inhibiting hormones of the hypothalamus. The release of estrogen during puberty triggers the development of female secondary sex characteristics such as uterine development, breast development, and the growth of pubic hair.

Gonads The gonads—ovaries in females and testes in males—are responsible for producing the sex hormones of the body.

As hormones travel through the body, they pass through cells or along the plasma membranes of cells until they encounter a receptor for that particular hormone. Hormone specificity explains how each hormone can have specific effects in widespread parts of the body.

Water-soluble hormones are unable to pass through the phospholipid bilayer of the plasma membrane and are therefore dependent upon receptor molecules on the surface of cells.

Classes of Hormones Hormones are classified into 2 categories depending on their chemical make-up and solubility: Tropic hormones provide a pathway of control for hormone production as well as a way for glands to be controlled in distant regions of the body.

The anterior pituitary produces 6 important hormones: Illustration of the endocrine system. The pituitary gland controls the release of thyroid hormones.

In men who have inherited genes for baldness testosterone triggers the onset of androgenic alopecia, commonly known as male pattern baldness. The endocrine system, on the other hand, is much slower acting, but has very widespread, long lasting, and powerful effects.

Glucocorticoids also function to reduce inflammation and immune response. Other Hormone Producing Organs In addition to the glands of the endocrine system, many other non-glandular organs and tissues in the body produce hormones as well.

ANP also reduces blood volume and pressure by causing water and salt to be excreted out of the blood by the kidneys. Situated in a small depression in the sphenoid bone called the sella turcica, the pituitary gland is actually made of 2 completely separate structures: The pituitary gland is divided into two parts: Within these islets are 2 types of cells—alpha and beta cells.

Hormonal Regulation The levels of hormones in the body can be regulated by several factors. In addition, it secretes hormones that stimulate or suppress the release of hormones in the pituitary gland.

For example, the thyroid hormones T3 and T4 require 3 or 4 iodine atoms, respectively, to be produced.Functional Anatomy exercise27 of the Endocrine Glands Review Sheet 27 Gross Anatomy and Basic Function of the Endocrine Glands 1.

Anatomy of the Endocrine System

Briefly explain this. The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs.

These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and. both the endocrine and nervous systems are major regulating systems of the body; however, the nervous system has been compared to an airmail delivery system and the endocrine system to the pony express.
