| Question | Answer |
|---|---|
| produces eggs and hormones | ovaries |
| houses the egg | follicle |
| produces estrogen and progesterone | corpus luteum |
| site of ferilization and serves as pathway that leads the early embryo to uterus | fallopian tube |
| site of implantation and fetal developmetn | uterus |
| separates uterus from vagina | cervix |
| birth canal | vagina |
| site where sperm revieves it flagellum tail | epididymis |
| houses testes and regulates tem. from optimal sprem production | scrotum |
| pathway for sprem form the testes/epidiymis to the glands which produce the needed material that will protect and sustain the sprem on its high enegry journey to an egg | vas deferens |
| allows egg to signal to a sprem its location and whether it is the appropriate species | chemotaxis |
| creates an electrical barrier to keep out competing sprem | calcium waves |
| creates a physical barrier to competing sprem | fertilization envelope |
| axial skeleton | skull, vertebral spine, ribcage |
| appendicular | shoulder girdle (clavical and scapula), pelvic girdle and appendages |
| 3 joint mechanisms | ball and socket, hinge, and pivot |
| 3 tissues that comprise bone as an organ | fibrous connective tissue, cartilage tissue and one tissue |
| yellow marrow is | stored fat |
| red marrow | site of blood cell production |
| 3 proteins involved in muscle contraction | tropomyosin, actin and myosin |
| muscle fibers are comprised of bundles of | myofibrils |
| myofibrils are made of repeating units of | sacromeres |
| what is the neurotransmitter of muscle contraction | acetylcholine |
| mineral ion moves tropomyosin | calcium |
| 4 steps of muscle contraction | detach, extend, attach, pull |
| what is the functional unit of muscle contraction | the sarcomere |
| nocireceptors | sense painful stimuli |
| thermoreceptors | sense temperature stimuli |
| mechanoreceptors | sense pressure and distortion |
| chemoreceptors | sense chem. stiumuli. ex. odor receptors in nose, taste buds |
| electromagnetic receptors | sense info from the electromagnetic spectrum |
| parasympatheic divison | rest and digest |
| sympatheic divison | fight or flight. body uses lots of enegry to respond quickly to stimuli |
| hindbrain | breating, digestion and eqilibrium |
| mindbrain | auditory and visual systems |
| forebrain | complex processes take place |
| temporal | auditory information |
| parietal | body sensations |
| occipital | visual |
| frontal | judgement, planning, problem solving |
| info is conveyed through nervous tissue by what two types of signals | electical and chemical |
| activates the parasympathic division of PNS | acetylcholine |
| regulates movement and attention | dopamine |
| regulates the sympathetic divison of PNS | epinephrine |
| regulates mood and digestion | serotonin |
| regulates sleep wake cycles | melatonin |
| low levels of serotonin | depression |
| high levels of serotonin | restlessness, hallucinations |
| low levels of dopamine | parkinsons disease, ADD/ADHD |
| high levels of dopamine | schizophrenia |
| endoderm | digestive system |
| mesoderm | muscle tissue |
| ectoderm | nervous tissue, external skin surface |
| 3 lines of cells that comprise a gastrula | endoderm,mesoderm, ectoderm |
| chorion | develops into placenta |
| yolk sac | gives rise to blood cells and gametes |
| allantois | develops into umbilical cord |
| what are 3 mechanisms that shape limbs and organs during embryonic development | apoptosis, migration, cells changing shape |
