Document Summary

Outline: microscope calibration, calculate drawing mags, basic tissue types (histo, observation of live cells, making elevated cover slips. Serial: complete set of sections of an embryo mounted consecutively on slides. Smear: suspension of cells spread out as a film. Types of slides: whole mount: entire cell/embryo mounted/embedded. *drawings must have title, microscope mag, drawing mag, labels. Tissues: collection of cells interwoven, and their extracellular products, act together to do particular functions. Tissues in early embryo: cells (cid:272)a(cid:374) (cid:272)ha(cid:374)ge epithelial (cid:373)ese(cid:374)(cid:272)h(cid:455)(cid:373)al. Joined at lateral surfaces by cell junctions: ha(cid:448)e disti(cid:374)(cid:272)t api(cid:272)al (cid:894)(cid:862)free(cid:863)(cid:895) + (cid:271)asal surfa(cid:272)es, mesenchyme: embryonic ct, between epithelial layers, also applies to cells at early stages of gastrulation. Frog skin epidermis: composed of 4-6 layers stratified squamous epithelium, basal = cuboidal cells, apical = squamous/flattened cells. Frog skin dermis: appears right underneath epidermis layer, divided into 2 regions in amphibians. These cells are mitotic, actively divide, push upwards.
