EEOB Missed Lecture January 12th Notes from book Chapter 1 Homeostasis A Framework for Human Physiology Physiology Study of how living organisms function Cells simplest structural units into which a multicellular organism can be divided and still retain the functions characteristic of life Cell differentiation process of transforming unspecialized cells into specializes cells 0 About 200 distinct cell kinds can be identi ed in terms of different structure and function 0 4 major cell categories 1 muscle cells 2 neurons 3 epithelial cells 4 CT cells Muscle cellstissue specialized to generate mechanical force Neurons and nervous tissue specialized to initiate integrate and conduct electrical signals to other cells sometimes over long distances Epithelial cellstissue specialized for selective secretion and absorption of ions and organic molecules and for protection Connective tissue cells and tissue connect anchor and support the structures of the body 0 Includes bers underlying most epithelial layers loose CT tendons and ligaments dense CT bones cartilage adipose blood Look at table 11 in book Body Fluid Compartments Body Fluids watery solution of dissolved substances such as 02 nutrients C02 and wastes Body uids exist in intracellular uid and extracellular uid 0 Intracellular uid contained in all cells of the body 67 of all uid in the body 0 Extracellular uid collectively uid in blood and spaces surrounding the cells Of this ECF a 2025 is uid portion of blood called plasma a 7585 ECF is interstitial uid 0 H20 accounts for about 5560 of body weight Lecture 1 from quotparty roomquot material and talk What is physiology 0 How an organism works 0 Ions and proteins 0 Systems respiratory circulatory etc 4 Critical equations 1 ATP ll ADP Pi energy 0 Our currency to spend to get things done 2 Glucose 02 ADP Pi ATP C02 H20 heat 0 Our job to make the most energy 3 C02 H20 l l HCO3 H o Aiding a transport of a key gas but creating pH problems pH changes cause homeostatic problems 4 PV nRT 0 Pressure Volume of items universal gas constant Temperature 0 Key for lungs blood vessels etc Homeostasis relatively stable maintenance of a body parameter l dynamic constancy Homeostatic Control System HCS Set of interconnected components 0 Purpose keep parameter at a set point SP Steady state SS parameter SP 0 System not changing dynamic constancy but energy E is used 0 Not equal to equilibrium no change in E 0 Because E is limited tradeoffs are required 0 Disturbances from SS within HCS o Reactive l responsivefeedback Negativefeedback physiologic response in opposite of disturbance direction therefore return to stable state Positivefeedback physiologic response in continued direction of disturbance therefore physiologically move further from normal SS 0 Proactive I preparation feedforward FF Limits degree of feedback required Less energy required 0 Biorhythm examples 0 O O 0 Body temp increase day decrease night Plasma GH decrease day increase night Plasma cortisol more uctuation with spike decrease at end of day and spike increase at end of night Urinary potassium increase day decrease night Lecture 2 Wednesday January 14th HCS Homeostatic Control System 0 Biorhythms gure 19 and 110 in the 11th 0 O 0 Graphs show set pattern night vs day for each physiologic response patterns are different for each responsesubstance level Biorhythms can be circadian daily lunar monthly or annual Ex we are more active during a full moon because there is more light and the fact that humans rely on vision to be active it s physiology we ve adapted over time Proactive vs reactive biorhythms Feedforward FF activity is proactive It s in our DNA to be active during the day and sleep at night an adaptation of our species internally we know time of day and our physiology act saccordingly the trigger is our internal clock not the environment a Adjustable within limits D Other species may be more active at night because of their DNA Whole purpose of FF is to set us up for survival so that we are proactive and don t waste energy being reactive o Acclimatization adjustable biorhythms within limits Ex Jet lag is experienced secondary to limits of acclimatization n Clock reset physiologic set point change a Acclimatization is adjustment of set point clock reset or temperature adjustment vs adaptation which is part of our genetic DNA a Setpoint and end points adjustable which is environmental usebased not a genetic change but an individual change I Usually reversible ex weight sleeping pattern etc 0 Exception developmental acclimatization 0 Ex smoking Mj irreversibly changes brain chemistry at a young age fetal alcohol syndrome 0 Control for HCS via Signals o Re ex Arc Figure 17 0 Stimulus l Receptor l Integration center eg CNS endocrine l Effector l Response l negative feedback l o How do we get the physiologic response from the effector SIGNALS chemical messenger 1 Endocrines hormones U Release by gland or neuron n Pathway plasma blood a Communicates with distant effectors 2 Paracrines U Release by most cells n Pathway IF

Why people love StudySoup

Steve Martinelli UC Los Angeles

"There's no way I would have passed my Organic Chemistry class this semester without the notes and study guides I got from StudySoup."

Jennifer McGill UCSF Med School

"Selling my MCAT study guides and notes has been a great source of side revenue while I'm in school. Some months I'm making over $500! Plus, it makes me happy knowing that I'm helping future med students with their MCAT."

Jim McGreen Ohio University

"Knowing I can count on the Elite Notetaker in my class allows me to focus on what the professor is saying instead of just scribbling notes the whole time and falling behind."


"Their 'Elite Notetakers' are making over $1,200/month in sales by creating high quality content that helps their classmates in a time of need."
