ANATOMY 2300.01 Lecture Notes - Popliteus Muscle, Dermis, Hominidae
Document Summary
Superior = cranial (head), inferior = caudal (tailbone) Layers of the skin: epidermis, dermis, subcutaneous. Ontogeny: the developmental history of an organism over its lifespan (pg. 3) Within the lifespan of an organism, ex: my life. Time frames in which evolution can occur, ex: 1000 years, lots of generations. Phylogeny: the evolutionary history of a group of organisms (clade) often depicted in the form of a dendrogram (family tree) Prokaryotic cells - no membrane bound organelles, smaller, cell walls, chloroplast. Eukaryotic cells - have membrane bound organelles, nuclei. Clade: a group composed of an ancestor plus all its descendants. Mya = millions of years ago t = extinct (this whole thing is a clade) i -------------------------- Eumetazoa - ingestive (gi tract) heterotrophs, true tissues/organs (made up of tissues) (contiguous/touching mass of cells, similar structure/function) Bilateria - two (bi) symmetrical sides ex: spiders, butterflies.
