PARATHYROID GLANDS Parathyroid glands are small glands of the endocrine system which are located in the neck behind the thyroid. There are 4 parathyroid glands in the human body. Parathyroid glands control the calcium in our bodies – how much calcium is in our bones‚ and how much calcium is in our blood. Parathyroid glands secrete or make a hormone‚ called parathyroid hormone or PTH. The parathyroid glands measure the amount of calcium in the blood every minute of every day and if the calcium

Gonadal sex hormones are produced by gonadotropins (FSH- Follicle Stimulating Hormone and LH- Luteinizing hormone) from the anterior pituitary gland located at the base of the brain. They stimulate male and female gonads to produce hormones of their own. FSH and LH secretion is controlled by GnRH (gonadotropin-releasing hormone)‚ which is a releasing hormone from the hypothalamus. The sex of an embryo is determined at fertilization‚ but secondary sex characteristics develop at puberty. Testosterone

Touch receptors called Meissner’s corpuscles are found in the papillary region of the dermis of the skin. When nothing is touching the skin‚ a voltage difference known as the (1) ___________ _____________ _____________ exists across the plasma membrane.

Adrenaline is a hormone that is produced in the adrenal medulla‚ which is in the inner adrenal gland. This gland sits atop the kidney. When put under stress this gland is stimulated by the nervous system and releases adrenaline into the blood stream. The release of adrenaline is a three step process. First‚ the hypothalamus produces hormones that stimulate the pituitary gland. Next‚ the pituitary gland then produces corticotropin hormones which are hormones that stimulate the adrenal glands that eventually

Eggs‚ Sperm‚ and Hormones Dionna Washington G150/PHA1500 Section 21 Structure and Function of the Human Body Felicia Stokes June 11‚ 2014 1. Sperm starts within the testis‚ in which it then passes into the epididymis and sits until it matures in the few days that it had waited. Then‚ the sperm is forced up into the ducts (vas deferens) into the seminal tubule and into the ejaculatory ducts‚ which moves semen into the urethra. Once that occurs‚ the semen covers the sperm and it moves into

Hormones Every living organism on Earth has some sort of organ system. For example‚ humans have their endocrine system. The endocrine system is a group of organs that release different biological substances called hormones. There are vast amounts of hormones‚ which means there are multiple uses that are necessary for survival. Hormones have multiple roles in the human body. For example‚ they assure that growth‚ development and maturation occurs properly and on time. Also hormones‚ help control

Week 14 Study Guide – The Endocrine System 1) What are hormones? Chemicals that are released to influence bodily functions. 2) How are hormones transported? Via bloodstream. 3) Why is the pituitary gland called the “Master” gland? Controls other glands and produces many hormones. 4) What are the two segments of the pituitary? Posterior and anterior pituitary. 5) Where is the thyroid gland located? Anterior to neck‚ inferior to larynx. 6) What are the symptoms of myxedema

The lobes of the brain. The cerebral cortex maybe be broken up into four lobes. Each lobe is named after the bones of the skull that cover them. In the very front is the frontal lobe‚ and behind that is the parietal lobe. At the very back of the brain we find the occipital lobe. And curving around each side of the brain we find the temporal lobe. Because the brain is made of two hemispheres there are pairs of each lobe. Frontal lobe: The most forward of the four lobes of the cerebral cortex

paper will be on the temporal lobes‚ which is what I believe to be the most important part of the brain. I will be explaining what its functions are and why they are so important. To begin the temporal lobes are structures in the cerebral cortex‚ they are located just above the ears‚ and are almond shaped. They are involved in the functions of hearing‚ language processing‚ and memory. Now that you know these details I will now go more into detail of how the temporal lobes control these functions and
