Chapter 2 Brain and Behavior The cerebral cortex outer layer of the cerebrum has the two largest hemispheres that covers the upper part of the brain which are divided into smaller portion called lobes. Corticalization is an increase in size of the wrinkling of the cortex and without this we would not be any smarter than any other animal. Cerebral hemispheres are divided into right and left halves of the cortex connected by thick band axon fibers called corpus. Hemispheric specialization‚ testing

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

- Medical Definition and More from Merriam-Webster. n.d.). So what does all this mean in layman terms? Pheochromocytoma is a rare tumor of adrenal gland tissue. It results in the release of too much epinephrine and norepinephrine‚ hormones that control heart rate‚ metabolism‚ and blood pressure. The adrenal glands are a part of the Endocrine system. It is this system that the body depends on to regulate normal body functions. Most of these types of tumors are benign and only about 10% are

Given your symptoms‚ you suffered from severe hypothermia. You are suffering from this condition as you were exposed to cold temperatures for a sustained amount of time. The human body works to maintain homeostasis‚ which is where the internal temperature of the body is kept in narrow limits. The human body must be kept within a certain range of temperatures. If the temperature of the body goes outside of this range‚ there is a system in body called the negative feedback system‚ which is where the

The pancreas is a large organ located in the right upper quadrant of the abdomen. It is gladuale organ that is made up of tissues and ducts. This gland is part of the digestive systemin relation to the endocrine gland that is attach to the first section of the small interstine known as the duodenunm. When the process of digestion occur‚ the pancreas secretes pancreatic juice containg digestive enzymes to break down carbohydtes‚ protein‚ and lipids for nutritn absorption in the small intestine.

1) What is the role of calcium ions during contraction of a skeletal muscle? Calcium is an important element for live. Calcium is found in the bones of animals and humans. In muscle contraction is produce as a result of Calcium ions ‚ Ca2+‚ It comes from rapid release from the cisternae of the sarcoplasmic reticulum which cause a chemical reaction between ATP and the myofilaments. Another important function of Calcium ions occurs during the state of resting muscle. During the state of resting
