ANIMAL PHYSIOLOGY LAB t Midterm Notes: Lecture 1-5
Lecture 1: Animal Physiology
- Animal physiology = study to understand how animals work
- ** Knut Schmidt Nielsen **
- Physiologists = study interaction between molecules, cells, tissues, organs, organ systems t understand
structure/function of org
o How parts of org work together so animals can perform activities and respond to environment
o Integrate genome sequences info into functional/evolutionary frame work
o How diff animals use similar building blocks for unique systems and overcome environmental challenges
- Most integrative life sci t based on chemistry, physics, math, molecular bio, eviro bio, ecology, evolutionary bio
- Phys integrates all levels of bio organization from molecules to cells and organ system to org
o Types of phys: cell and molecular, system, organismal, ecological, integrative
- ** see table 1.1 in textbook **
- Physiological diversity in animals results from evolution
- Common phys processes:
o Animal texting = animal experimentation, animal research, in vivo testing t use of non-human animals in
experiments
o Human testing = unethical, very regulated t e.g. twin studies conducted by Mengele in Auschwitz
- Animal testing used since prehistoric times t references to it in Greek writing in 2nd/4th BCE
o Aristotle and Erasistratus one of the 1st to perform animal experiments
o 'ovAZ(Z}(À]À]]}v[t physician in 2nd CE, dissected pigs and goats in Rome
- Major figures of physiology = fernal, Vesalius, Schwann, Bernard, cannon, scolander, prosser, Nielsen, Bartholomew,
hachachka and somero
- Model species = org studies by community of researchers
o Has certain features good for experimenting t e.g. mice = transgenic, unusual anatomical features, squid =
large axon/neurotransmission, xenopus = large oocytes/RNA translation, worm = c. elegans development/each
cell known
o Understanding process in model help to show how process works in other species
o Rapid growth in # of species w/ genome decoded
- Mice = best model of inherited human diseases, share 99% genes w/ humans
o Genetically modified mice = model for human diseases
o Most commonly used vertebrate b/c of size, cost, east handling, fast reproduction
- Rats = for physiology, toxicology, and cancer research
o Genetic manipulation harder than mice
o SAGE project 1st transgenic rat in 2009
- Rabbits = used for production of polyclonal antibodies
- Other rodents for animal experiments = guinea pigs, hamsters, gerbils
- Non-human primates/NHPs: macaques, rhesus monkeys, cynomolgus monkeys, squirrel monkeys, spider monkeys, owl
monkeys, marmosets, baboons, chimps
o Used for toxicology t AIDS, hepatitis, neurology, behavior, cognition, reproduction, genetics,
xenotransplantation
o 1st transgenic primate rhesus macaque in 2001
o Helps polio vaccine development
o Help understand development of deep brain stimulation for Wl]v}v[ disease

o Drosophila = genetic manipulation
o Crayfish = synaptical plasticity, phasic and tonic differentiation
o Sea slug = learning and memory
o armadillos
- experiment has to 1st be approved by Institutional Board of Ethics
- ïZ[APµ](}v]uoZW
o Reduction = researchers get info from fewer animals or more info from same # of animals t experiment not
unnecessarily duplicative
o Replacement = prefer non-animal methods if possible, so other methods must be considered and animals only
used when necessary
o Refinement = minimize potential pain, suffering, distress, and enhance animal welfare t pain relief provided
unless it interferes with the study and testing causes as little suffering to animal as possible
- 1st animal protection law passed in British parliament t 1822
- Cruelty to Animal Act 1876 = 1st law to regulate animal testing
o Legislation promoted by Darwin t À]À]]}vZ]](]o(}o]vÀ]P]}v}vZÇ]}o}PÇVµv}(}

}µUZ}Áv]uo[v(}]}o]À
o 1st English air pump made for Robert Boyle 1758 t Boyle knew animals need air to live
o Lavoisier in 1780s discovered oxygen in air is what supports life t drew analogy between cell respiration and
simple combustion
- Henry Bergh founded American Society for Prevention of Cruelty to Animals ASPCA in US in 1860s
- American Anti-vivisection Society AAVS = organization founded in 1883
- Animal Welfare and Rights Organizations = PETA t Ppl for Ethical Treatment of Animals, and BUAV t British Union for
Abolition of Vivisection
- Animal testing controversies since 17th CE

- 17th ]v]uov[(o]vl}(ol}(}v]}µvss
- Unclear if invertebrates feel pain
- Euthanizing lab animals = induce rapid unconsciousness and death without pain or distress:
o Inhale gas (e.g. CO2) by being placed in a chamber/face mask, with/without prior sedation/anesthesia.
o Sedatives/anesthetics (e.g. barbiturates) given intravenously/inhalant.
o Amphibians and fish immersed in water containing anesthetic (e.g. tricaine)
o Physical methods with/without sedation/anesthesia depend on method
o Decapitation/beheading for small rodents/rabbits.
o Cervical dislocation (breaking neck/spine) for birds, mice, immature rats, rabbits
o Maceration (grinding into small pieces) on 1 day old chicks

t only used on rodents
o Captive bolts t causes death by a brain concussion for dogs, ruminants, horses, pigs, rabbits
o Gunshot when v]vP]À}ov[µ
o Some physical methods only acceptable after animal unconscious.
o Electrocution for cattle, sheep, swine, foxes, mink after unconscious by a prior electrical stimulation
o Pithing = inserting tool into the base of brain on animals already unconscious
o Slow/rapid freezing, or air embolism with prior anesthesia to induce unconsciousness
- Tom Regan = said animals have moral rights but kill animals permissible if saving a human

Over 90% improved by at least one letter grade.

Leah — University of Toronto

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.
