2 11 Notes 13 02 2014 09 52 00 HPV continued similar to flu 2 vaccines gardisil and cervarix controversy over vaccinating children infects everyone sometimes causes cervix infection many mixed opinions towards hpv and people s perspetives on it 1 99 hpv does NOT lead to cancer 2 women with regular pap tests get little benefit regarding surviving 3 not sure how long hpv vaccination lasts 6 7 years right now is the cancer known time 4 side effects are rare and minor but sometimes serious CDC shows that hpv cancer in many places like mouth throat etc boys AND girls should be vaccinated gov view and many states have own laws to educate fund require the vaccinations Anti angiogenesis drugs cancer grows through its blood supply so these drugs try to cut off that blood supply to stop the tumor from continually growing Longevity expected lifespan species specific genetically controlled long live mutants 1840 life span is UNDER 50 years today USA baby is 78 years why do humans plants age 1 Consequence of positive activities like reproduction that have negative long term effects on the body 2 No reason to use energy to repair body functions when we are longer competitive with reproduction committing energy to certain repair mechanisms may not be biologically worthwhile can we reduce aging Many products and such say we can but starving yourself may extend life and it may cause continual stress leading to a higher level of cell repair functions Why menopause Stops women from being able to have babies Does it increase the chance of a women s genes being present in future generations Something that has evolved so it MUST benefit having babies Having babies is dangerous because if the baby is born then mom dies NOBODY can take care of the kid That helps mom s genes indirectly pass on 1 egg cells dna age in ovary and so may accumulate deleterious mutations where sperm are continuously new so it prevents you from 2 babies are dangerous so many mothers die from birth If gramma is wasting young sperm on old eggs alive and not threatened with pregnancy she can take over parenting more kids survive 3 grandma s help with feeding mom can stop breastfeeding sooner and get pregnant again sooner 4 with no risk of pregnancy women live longer and gain experience of infrequent disasters so that knowledge helps people survive I know what to do when we have a fire flood Need that societal memory so more people survive and pass those genes on people Dementia loss of cognitive functions thinking memory behavior Alzheimer s disease most common cause of dementia with older Abnormal clumps amyloid plaques and tangles bundles of fibers neurofibrillary tangles in brain tissue cause this The connections between nerve cells are lost and so the brain shrinks A misfolding of excreted proteins cause problems inside the brain like prions RUINS OUTSIDE OF CELL Tangles are twisted fibers of proteins that accumulate inside cells and destroy internal structure RUINS INSIDE People don t know what controls it and the rules just that the tangles and clumps are end result in the next 10 15 years of people with dementia will continue to increase and it will become more expensive to pay for their care impacts millions 1 8 over 65 has it major challenge that scientists want to try and understand know the 2 proteins but not WHY it happens How should we define human death when can organs be removed for transplantation when all brain activity stopped all higher function brain activity stopped heart beat stopped how long case court blocked hospital from taking kid off life support after being brain dead 3 days case doctors in Hungary delivery baby boy his mom is brain dead for 3 months during pregnancy donate organs She was kept alive LONG ENOUGH to save kid through c section case woman pregnant and family wants life support turned off because those were her wishes and hospital didn t want to because it would terminate the fetus and violate a TX law FINAL DECISION IN FAVOR OF FAMILY 2 13 13 02 2014 09 52 00 Class Survey Results longevity of humans does exist and should be around 90 100 or 120 129 years baby expectancy today 78 years dispatch shows Ohio is one of DEADLIEST states for babies ranked 48th because over 1000 die before 1 yr old deals with mother care most of the time very high in franklin county and higher among blacks than whites highest cause of deaths low birth weight disorders Reproduction randomness of partner not actually random people who look most similar to you regarding features culture background goals etc pheromones released chemicals that trigger behavioral responses in other members of the same species In many species these attract ppl of the opposite sex human pheromones Evidence showing with dorms menstrual periods converge and occur at the same time experiment armpit secretions from men were swabbed 3 times a week on the upper lip of women with menstrual cycles and in THREE months cycles all approached the same of days Men s Reproductive Systems bladder in the front tubes go behind the bladder sperm collected in epididymis survives better at lower body temperatures which is why testes are outside of the body circumcision removes foreskin that covers glans penis often times a religious things other times it s a societal action o 75 boys in us are circumcised o medical benefits of doing this o not all states fund circumcision through medicaid Sperm lobule compartment found inside testis where sperm develops from outside to inside outside to center part of tubes and are released then move through tubules to epididymis Epididymis where most sperm is stored has egg surface digesting enzymes sperm head 23 chromosomes acrosome head middle piece mitochondria flagella tail to swim spermatogenesis 1 spermatocyte 4 sperm oogenesis 1 oocyte 1 egg and 3 non polar bodies vasectomy cut off tubes to prevent from going to penis Erections sexual arousement arteries expand blood enters erectile tissue bloods compress so decrease flow and it s an erection viagra maintains erection because blocks enzyme that breaks stuff down so it can t INITIATE but can MAINTAIN work on downside Ejaculation sperm leave testis that were collected in epididymis fluids add alkali increasing ph in vagina and providing nutrient energy sperm and seminal fluid enter and muscles close bladder exit preventing urine flow ejaculation 1 million sperm ml after muscle relaxation and male refractory period immediately after there s a cooling off period WOMEN
