constantly monitoring blood pressure. They send messages containing any changes through the central nervous system to the medulla oblongata. The medulla oblongata then puts out an increase in sympathetic input to release adrenaline‚ a hormone of the endocrine system‚ which causes vasoconstriction. The vasoconstriction would then cause the blood pressure to rise back to normal. The body also regulates blood pressure by increasing or decreasing sympathetic and parasympathetic input of the nervous system

Dissection Exercise 3 1. How do the locations of the endocrine organs in the fetal pig compare with those in the human? They are similar except for the pancreas and the adrenal glands. In the fetal pig‚ the adrenal glands are medial to each kidney and inferior to the pancreas rather than atop to kidneys and superior to the pancreas as in humans. 2. Name two endocrine organs located in the throat region? Thymus gland and thyroid gland. 3. Name three Endocrine organs located in the abdominal cavity. Adrenal

is a study of the structure and function of the human body. The course covers in detail the human body from its biochemical and sub cellular aspects through tissues. Special emphasis is given the integumentary‚ skeletal‚ muscular‚ nervous‚ and endocrine systems. The lecture and laboratory are correlated to provide an overview of the interrelationships of normal human anatomy and physiology. Biology 111 meets the general education requirement for group II-science. b. Learning Outcomes for this

1. Why is cell differentiation important in the formation of organ systems? - When a cell differentiates‚ it becomes more specialized and it may undertake major changes in its size‚ shape‚ metabolic activity‚ and overall function. Cellular differentiation is important and occurs so cells can specialize for distinct functions‚ such as an organ system‚ within an organism. All cells in the body‚ beginning with a zygote‚ contain the same DNA then go through cell growth and division‚ also called mitosis

LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture

with weight loss this strategy doesn’t always work. There are environmental factors influencing weight loss that go beyond the calories consumed versus calories burned model. In the past few decades there’s been substantial research on chemical endocrine disruptors‚ some of which are termed “obesogens”‚ and there’s a link between consumption of these chemicals and susceptibility to weight gain. With the United States struggling with weight loss‚ it’s time for health care practitioners to look beyond
