PDBio 220: Brown BYU Embryology & Histology || with Complete
Solution.
Oocyte correct answers A cell in an ovary that may undergo meiotic division to form an ovum
Cleavage correct answers Period in between the Fallopian tube and the ovary where the egg us
undergoing mitosis
Morula correct answers At the end of cleavage when the cell is 16 cells in number
Blastocyst correct answers The stage of the cell that implants into the uterine wall
Blastocoel correct answers Fluid filled area of a blastocyst (nutrients located here)
Trophoblast correct answers Cell after fusing to uterine wall
Cytotrophoblast correct answers is considered to be the trophoblastic stem cell because the layer
surrounding the blastocyst remains while daughter cells differentiate and proliferate to function
in multiple roles.
Syncytiotrophoblast correct answers Uterine wall cells are broken down by the trophoblast and
made into cytoplasmic gew. As a result the Hypoblast is submerged into the uterine wall and it
reforms over the hypoblast completely covering it.
Gastrulation correct answers is a phase early in the embryonic development of most animals,
during which the single-layered blastula is reorganized into a trilaminar ("three-layered")
structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm,
and endoderm.
Nervous, Muscle, Epithelial, Connective correct answers Four Basic tissue types
, Special characteristics of epithelial tissue correct answers Selective permeability
Secretion
Avascular
Rapid regeneration
Where epithelial tissue is found correct answers GI tract
Hollow organs
Skin surface
Epithelial functions correct answers Cover or lining
Tight junction correct answers Apical and basal compartments
Seal cells together to form a barrier
Anchoring Junction correct answers Stabalize epithelial tissue. On lateral and basal surface of
cells
Desmosomes correct answers Type of anchoring junction, connects like a button
Hemidesmosomes correct answers Type of anchoring junction, connects like a zipper
Adherens correct answers Type of anchoring junction, adhere to basement membrane
Simple Squamous correct answers Flat, one layer, epithelial tissue
Stratified Squamous correct answers Flat, several layers, epithelial tissue
