Essay on Bio lap report endocrine system

In this experiment, contractions of the earthworm gut are measured in an organ bath with a force transducer. The effect of neurotransmitters and ionic concentrations on contraction strength and rate will be investigated.

12. Both the nervous system and the endocrine system are used to convey messages throughout the body and coordinate organs, systems, and behavior. Compare and contrast how these two systems function.

3. Identify the histological features (listed below) of the major endocrine glands on microscope slides.

their relation to the above questions. Describe the role of the nervous system, adrenal glands, kidneys and

I. Describe the role of the following hormones in the formation of urine, specifically explain the stimulus for their release, actions (decrease/increase GFR) and whether or not dilute/concentrated urine results):

INSTRUCTIONS: All questions apply to this case study. Your responses should be brief and to the point. When asked to provide several answers, list them in order of priority or significance. Do notassume information that is not provided. Please print or write clearly. If your response is not legible, it will be marked as is and you will need to rewrite it.

Purpose: What is the purpose of this exercise? Is there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken.

Learning Objective 2: 18.6.2 Describe the location, histology, hormones, and functions of the anterior and posterior pituitary.

The adrenal glands are composed of two sections, the medulla and the cortex. The medulla part of the gland is what produces adrenaline-like hormones. The cortex produces a group of hormones called corticosteroids

Adrenal glands are endocrine glands that sit atop the kidneys (Shier et al., 2009). The adrenal glands secrete hormones that increase heart rate, the force of cardiac muscle contraction, breathing rate, elevate blood pressure and blood glucose level. This activity prepares the body foe energy expending action, sometimes called fight or flight responses (Shier et al., 2009).

In 1954, the FDA approved growth-stimulating hormones for use in the general public, creating an opportunity to make that dream an unsettling reality (FDA 1). Not only were these synthetic drugs encouraged as a supplement during human pregnancies, but for use in livestock as well (CDC 1). Aiding in the conversion of feed to fat in animals, dramatically increasing the rate of growth, artificial growth hormones seemed like the cattleman’s miracle elixir. However, in 1971, the FDA banned the use of DES (diethylstilbestrol, synthetic estrogen) in humans, which was the primary growth hormone available for human consumption (CDC 1). Use of DES in

Compare and /or contrast the anatomy of the White Rat with that one of the Human body.

Hypothalamus is taking control of both adrenal cortex and adrenal medulla. When the stress occurred, either emotional or physical trauma, prompts the hypothalamus to stimulate a part of the adrenal glands. The medulla and cortex secretes different hormones.

B. Matching type. Match concepts in column left with the best answers in column right. Write letters only.

Unlike plants, humans require organs and systems to produce hormones. One of the major systems we need is the endocrine system. The endocrine system is the collection of glands of an organism which secrete hormones directly into the circulatory system, which then distributes the hormones to specific organs. The main endocrine glands include the hypothalamus, pituitary gland, pineal gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, gonads(testes, ovaries) and thymus. Each have specific operations that they complete which make us function properly. The study dealing with the endocrine system and its diseases is endocrinology, and many people don’t know the endocrine system, like the nervous system is an information signal
