is for singal integration‚ it consists of the axon hillock. The signals transmitted from the first zone is integrated in this region. If the signal is strong enough‚ an action potential would be initiated. Third zone is specialized for signal conduction‚ it consists of the axon. The axon carries the information‚ usually from action potentials‚ from the cell body to the axon terminal. The fourth zone of a neuron is for signal transmission to target cells‚ it consists of the axon terminals. These axon

we eat turn into things such as carbohydrates‚ fats‚ and proteins. Carbohydrates are‚ any of a large group of organic compounds occurring in foods and living tissues and including sugars‚ starch‚ and cellulose. Protein‚ such as meat‚ eggs‚ and beans‚ consist of large molecules of protein that must be digested by enzymes before they can be used to build and repair body tissues. An enzyme in the juice of the stomach starts the digestion. Further digestion

Physiology & Anatomy Lab SC 145L Anatomy & Physiology I Lab Chemical and Physical Processes of Digestion Introduction: In this lab‚ we will see how different chemical processes occur as we observe how different enzymes digest different substrates and produce subunits. Key Terms: (found in bold in Lab Manual) Please define all bold terms in your own words: Enzymes- Large protein molecules made by your body cells. Catalyst- Without becoming part of the substance it will change the rate

mouth is a part of the body where people use mechanical digestion and use their teeth to break down their food. With the help of saliva produced by the salivary glands‚ which produce enzymes‚ food is able to be broken down further. This is also the place where ingestion takes place” “What are enzymes” “Enzymes are very efficient catalysts for biochemical reactions. In the mouth there’s an enzyme that will help your food undergo chemical digestion” “What is it” “It is amylase. Which help digest starch

Digestion Lab Abstract – The purpose of this lab was to understand how different solutions played a role in the digestion protein. By looking at different variables‚ such as temperature‚ and pH we’re capable of understanding just how certain substances functioned and when they didn’t. The data for all labs are clear and concise and give a clear understanding of what solutions work best. All three labs were placed in a warm water bath set at 37’C to stimulate the reaction as if it were taking place

Pancreatic Cancer Cancer of the pancreas is the fifth most common cause of death in both men and women. Pancreatic cancer affects approximately 33‚730 Americans each year. The pancreas is a gland found behind the stomach that is shaped a little like a fish. The pancreas is around six inches long and less than two inches wide‚ and it spans across the abdomen. The pancreas makes enzymes to break down food. Jaundice‚ a condition marked by the yellowing of the skin and eyes commonly occurs

What is pancreatic cancer? Pancreatic cancer is an aggressive form of cancer that develops in the tissues of the pancreas. Located in the abdomen behind the lower part of the stomach‚ the pancreas aids in digestion. It contains both exocrine glands (which produce enzymes that help the body digest food) and endocrine glands (which produce hormones‚ including insulin‚ that help control blood sugar levels in the body). Pancreatic cancer is hard to diagnose and once it is found it has usual spread to
