The Brain Homework (using the book) p.256 to 261.

Outline the parts and function of the four major parts of the brain: (1) cerebrum, (2) diencephalon, (3) cerebellum, (4) brain stem. (Images helpful) - The cerebrum contains the cerebral hemisphere, the cerebral cortex( voluntary movements), the primary motor area, the primary somatosensory area, the association area, the processing centers and the central white matter. - 2 halves, the left and right hemispheres.
 * 1. The cerebrum is the largest part of the brain in the body. It is the last place to receive sensory input and carry out integration before voluntary motor responses. It also helps with communication and activity in the brain.

- The diencephalon contains the hypothalamus, and the thalamus. - hypothalamus: regulated hunger, thirst, body temperature and water balance. - thalamus: receives the sensory except smell.
 * 2. The diencephalon is the region that encircles the third ventricle.

3. "The cerebellum lies under the occipital lobe of the cerebrum and is separated from the brain stem by the fourth ventricle"It has 2 portions that are held together by a narrow portion. It receives sensory from the eyes, ears, joints, and muscles. Helps you with your posture and balance. You can stand or walk correctly. helps your muscles work together for good coordination. You can learn new skills, such as the hitting a baseball.

4. The brain stem which is the mid brain, the pons, and the medulla oblongata. -midbrain: reflex center for visual, auditory and tactile responses. -pons: "bridge", regulates breathing. reflex- head movement. - medulla oblongata: reflex center: regulating breathing, heartbeat, blood pressure. also is the reflex center for vomiting, coughing, sneezing, hiccuping and swallowing.

(5) What is the function of the limbic system? The function of the limbic system is that it blends primitive emotions and higher mental functions into a whole. It explains why we sex, eating and netaal stress cause high blood pressure. (6) What limbic system structure is involved in the flight or fight reaction. Explain.
 * The amygdala. This part of the brain can cause you to have mod swings or to feel too much emotion at a time and can create a scare of fear. This area of the brain can use past emotions and can trigger a current situation and that can trigger the flight or fight reaction. Judging from previous situations that you have been in, you will act a certain way just my feeling that same emotion.

(7) What limbic system structure is involved in learning and memory. Explain. it blends primitive emotions and higher mental functions into a united whole. It is when you feel pleasure from sex, or food and you experience that memory just by learning from activities. The activities are sexual behavior and eating. Mental stress that can cause high blood pressure. The structure contains amygdala=emotion overtones- the flight, fight reaction and the hippocampus= learning and memory.

(8) Describe the various types of memory. -what is happening at a certain time. what is happening right now. - you can remember things like phone numbers. - things you can recall. - a combination of long term memory which contains numbers, and words. - this is a memory that allows you to remember people, and places, events, - you have learned teh skill like riding a bike, and you just know how to do it, without learning how to do it again. This memory has to do with remembering how to do certain activities. - vision is stored in the vision association area, sounds are stored in the suditory associated areas. memory in the cellular level.
 * Short- term memory
 * long- term memory
 * semantic memory
 * episodic memory
 * skill memory
 * long term memory storage and retrieval
 * long term potentiating

(9) What appear to be the roles of the left hemisphere of the cerebrum and the right hemisphere? Left: language and speech, right: has many different functions. (10) What is Wernicke's area and Broca's area? - The Wernicke area is the part of the brain that is devoted to language and speech. You need this to be able to talk and understand what people are saying. It is on the left side of your brain.
