Lab 2 Cells & Tissues
• Cell theory• Cell structure, review pp. 17 & 18• Histology: epithelial, connective, muscular &
nervous• Slides– List on pp. 16 (plus frog skin)
Frog skin—simple squamous
Simple cuboidal
Simple columnar
Human blood
Frog blood
Loose areolar CT
Hyaline cartilage
Adipose
bone
Smooth muscle
Skeletal muscle
Lab 4 Development
• 5 phases• 3 germ layers• Cleavage: radial v. spiral• Development in sea star (slide) & frog (model)– Zygote, morula, blastula, gastrula, neurula (frog),
larva
• Development in chick (slides)• Extraembronic membranes (4)
Lab 6 Protozoa
• Single celled, eukaryotic, animal-like protists• Flagellated protozoa– Euglena (live & prepared)– Trypanosoma
• Amoeboid– Amoeba (live & prepared)– Foraminiferans (slide)– Radiolarians (slide)
Lab 7 Porifera
• Sponges– Spicules of calcium carbonate or silica– Fibers of collagen or spongin– Outer pinacocytes– Inner choanocytes– Mesohyl in the middle
• Canal systems: asconoid, syconoid or leuconoid
Sponges
• Class Demospongiae: horny sponges• Class Calcispongiae: calcareous sponges• Class Hexactinellida: glass sponges
Phylum Cnidaria
• Radial symmetry• Diploblastic• Outer epidermis• Inner gastrodermis• Cnidocytes—nematocysts• Polyp & medusa stage
Cnidaria
• Class Hydrozoa– Obelia (prepared slide)– Hydra (live & prepared)– Physalia (preserved)
• Class Scyphozoa– Aurelia
• Class Anthozoa– Sea anemones & corals
Lab 9 Platyhelminthes
• Flatworms• Triploblastic & bilateral• Class Turbellaria– Planaria (live & prepared slides)
• Class Trematoda– Complex life cycle—2+ hosts– Clonorchis sinensis—human liver fluke (slide)– Fasciola hepatica—sheep liver fluke (slide)– Cercaria—tadpole like stage (slide)
