The pituitary gland was observed to be in 2 distinct parts and separated by a middle ridge (little ravine). I observed the gland to be composed of two tissue types, an adenohypophysis (anterior lobe) derived from buccal ectoderm and a neurohypophysis (posterior lobe) also called pars nervosa derived from neural ectoderm. The adenohypophysis contains mainly cords of glandular epithelium surrounded by blood vessels and some C.T. The major anterior portion of this lobe is called pars distalis. A smaller portion, pars intermedia, lies between the pars distalis and the posterior lobe neurohypophysis. The posterior lobe contains mainly…

With regard to the anterior pituitary, neurons in the hypothalamus secrete a group of compounds called releasing hormones that are absorbed into the primary capillaries. These compounds in turn effect the secretion of stimulating hormones into the secondary capillaries to take them all over the body by the blood. Some of these from the anterior pituitary are called tropic hormones because they stimulate specific endocrine glands. The two targeting the reproductive organs are called gonadotropins. Secretion of most tropic hormones is achieved by negative feedback of the target gland hormones acting on the hypothalamus. The non-tropic hormone from the anterior pituitary is…
The pineal and pituitary glands are located in the center of the brain. The pineal gland is in the center of the brain, regulates activity levels throughout the day, and secretes melatonin, which controls the body’s sleep wake cycles. Lack of melatonin in the body causes what is known as “jet lag”, which occurs when the body’s proper sleep cycle is interrupted. The pituitary gland lies on the underside of the brain, and produces the largest number of hormones in the body, thus called the “Master Gland”. This gland influences blood pressure, contractions during childbirth, milk production, sexual behavior and interest, growth, and hydration (Morris and Maisto, 2002).…
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 release of reproductive hormones, which are required during breeding seasons. (Campbell and Reece, 2011) The hypothalamus signals travel to the pituitary gland, which is located at the base of the hypothalamus with posterior and anterior parts. The anterior pituitary is an endocrine gland that synthesises and…
OVERVIEW The endocrine system, like the nervous system, controls body activities to maintain a relatively constant internal environment. The methods used by these two systems are different. This chapter describes the difference between endocrine and exocrine glands, the location of the endocrine glands, and the hormones they secrete (objectives 1 and 6). It explains the nature of hormones, the substances that function as hormones, how hormones affect target tissues, how the secretion of hormones is controlled by a negative feedback system and the nervous system, the general function of each hormone, and the result of too little or too much of each hormone (objectives 2-5, 7, and 8). In addition, the text distinguishes between physical and psychological stress, and describes how the endocrine system mediates the stress response (objectives 9 and 10). A knowledge of the function of the endocrine system is basic to the understanding of how metabolic processes are regulated to meet the changing needs of the body.…
The adrenal gland of the endocrine system produces a number of hormones, including cortisol. Cortisol plays a number of roles throughout the body. It helps with regulating the body’s blood pressure, which keeps the cardiovascular system functioning normal. It helps to react to stress by converting proteins,…
The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things. The endocrine system is a very important system in the human body. There are many endocrine glands in this system, including -but not limited to- the pituitary gland, hypothalamus, pineal gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, gonads, placenta, thymus, heart and gastric and intestinal mucosa. Endocrine glands are ductless glands that secrete hormones directly into the blood stream. The basic function of the endocrine system is to maintain homeostasis. The endocrine system uses hormones to communicate/control.…
The endocrine system releases hormones throughout our body and travels through the blood stream. Our hormones can cause many different reactions throughout our body and the reactions can have a big part in a human’s behavior. We have seven glands in our bodies, such as thyroid, pancreas, gonads, pineal gland, parathyroid, adrenal glands pituitary gland. Our glands can produces diverse hormones, each one of our hormones has a specific affected on a human’s body. This can cause sexual needs, moods, and energy. The pineal glands and our pituitary glands are located in the center of our brains. Pineal glands is located in the center of the brain that does regulates our activities levels on a daily bases. This is where melatonin is made in the center of the brain which controls our bodies sleep cycles, when we wake up and when we sleep. If our bodies lack the melatonin this causes our sleep schedules to be off which will make a person’s moods change, because of the lack of sleep. The pituitary glands are is on the underside of our brain, which produces the largest amount of hormones in our bodies. This is also known as the Master Gland. The Master gland will influences our blood pressures, sexual behavior and the interest, milk productions; contractions will give child birth, growth and the hydration. A pancreas glad is near…
The endocrine system is a relatively small yet extremely important system of the human body. Without it, humans would not survive. Daily function and long-term development depend upon hormones secreted from glands in the endocrine system. One little mutation can give a person serious problems for his or her entire…
