They are by no means a substitute for going to lecture!! Also, for this study guide I did not write ALL the functions of each section, just what the professor went over during lecture. To understand the full capacity of each section of the brain please read the textbook thoroughly. Page 1070 1084 in textbook 8 th Edition BRAINSTEM functions in homeostasis, coordination of movement, conduction of information to and from higher brain centers Midbrain Center for receiving and integrating several types of sensory information. Contain neurons that involve eye movement. Pons (bridge) Modulatory effects of respiration. It is a bridge to the cerebellum Medulla oblongata Regulation of heart rate and blood pressure Cardiovascular and respiratory centers Nuclei of vagus nerve Cerebellum involved in movement and coordination detects pressure on our joints when we stand up/sit down can sense where every part of your body is located when we close our eyes (ex: you can sense where you nose is and touch it when you close your eyes) senses acceleration and movement o if someone were to have damage to the cerebellum, they will have uncoordination and loss of gravity sensation Cerebellum TA: Victoria Ha Section: (B03) Monday 5:00-5:50pm Solis 111 Email: viha@ucsd.edu Office Hours: Thursday Hi Thai 2-3pm-Midbrain, medulla oblongata, and the pons contain cluster of neurons that form a network and make up the reticular activating system, which stimulates and keeps the brain awake. Sleep involves in inhibition/decrease in the activity of this system. Thalamus : there are one on each side of the brain relay station for sensory and some motor input going to the cerebrum Hypothalamus (under the thalamus) located at the base of the brain most important brain region for the control of homeostasis some of its activities are: o temperature regulatory center o osmoregulation that detect changes in osmolarity o pressure and volume regulation o main sympathetic center o controls thirst and appetite o sexual/ labor behavior o aggression o contains the circadian clock/ biological clock. The clock is reset by some stimuli (such as light) o secretes two horomones: ADH (anti diuretic horomone): reabsorption of water in the kidneys TA: Victoria Ha Section: (B03) Monday 5:00-5:50pm Solis 111 Email: viha@ucsd.edu Office Hours: Thursday Hi Thai 2-3pm Oxytocin: involved in labor (fetus activate stretch receptors in uterus positive feedback contraction of uterus oxytocin release milk release) And causes mother to bond with their baby....
