Laboratory 8 - Endocrine System Endocrine Gland Histology PhysioEX 9.0 – Endocrine System Physiology (Exercise 4) Endocrine Gland Histology Objectives 1. To understand the function of the endocrine system 2. To learn about the major endocrine glands‚ the hormones they produce‚ and the effects they initiate 3. To familiarize the student with histological identification of various endocrine glands Background The endocrine system consists of cells and tissues that secrete chemical

homeostasis of serum (blood calcium) levels through the use of the thyroid and parathyroid gland. The body maintains homeostasis of serum levels through the use of the thyroid and parathyroid glands because the thyroid secretes calcitonin and the parathyroid secretes parathyroid hormone. Both of these hormones help regulate blood calcium levels. 4. Explain the role the hypothalamus and pituitary gland

Written Assignment 1 1) Identify the organs of the endocrine system‚ including their locations and structures. Hypothalamus: Is located below the thalamus just above the brainstem. Pituitary: Is location within the sella turcica which is a dip in the sphenoid bone. Structures are tropic hormone and neurohypophysis. Thyroid: A) Location: anteriorly‚ above the thyroid glad. B) Structures are the isthmus connecting the two lobe and thyroid follices and network of capillaries Adrenal:

blood conditions or other variables within living organisms‚ the purpose of homeostasis is to provide a consistent internal environment for set processes to occur. The endocrine system is made up of glands that produce hormones and release them into the blood‚ they cause certain reactions to occur in specific tissues. The endocrine system affects a large number of the body’s functions‚ including‚ metabolism‚ sexual function‚ reproduction‚ moods‚ and development. (dummies.com) The urinary system is

heredity on human behavior. This picture is what leads to the development of the nervous system and endocrine systems of a particular individual‚ which then produce hormones. Those hormones then switch on behaviors. Genetics is the study how traits are passed from one generation to the next through genes‚ which are found on chromosomes. Genes are responsible for the development of the nervous and endocrine systems; therefore‚ genes can influence the chance of a certain behavior occurring in a certain

Luteinizing hormone is created by the pituitary gland and it is very important in the reproductive process as it allows ovulation to take place‚ alongside follicle stimulating hormones. The intermediate pineal is responsible for the production of melatonin which is considered to regulate the biological clock in humans‚ as it helps the brain to synchronise to daylight. The parathyroid gland is an extension of the thyroid gland‚ though this produced a separate hormone named parathormone
Premium Nervous system Hypothalamus Brain
In vertebrates‚ the hypothalamus‚ located at the base if the brain‚ plays a central role in integrating the endocrine and nervous systems. The hypothalamus receives information from nerves throughout the body and the brain. (Mousa and Mousa‚ 2003) In response‚ the hypothalamus initiates endocrine signalling appropriate to environmental conditions. In many vertebrates’ nerve signals from the brain pass information to the hypothalamus about seasonal changes‚ therefore the hypothalamus regulates the
