Quiz 3 study guide Flashcards
A cleft lip occurs when the maxillary process fails to fuse with the
Globular process
One of the first structures of the face to develop in the primitive embryo is the
Stomodeum
When a cleft of the alveolar process is present, it occurs between the:
Lateral incisor and canine
During embryonic development, neural crest cells migrate to the branchial arches and surround the
Mesoderm
Fertilization and implantation occur
Preimplantation period
Period involving embryo growing to fetus
Fetal period
Second week to eight week of prenatal development
Embryonic period
Embryonically, the mandible is derived from
First branchial arch
Action of one group of cells that leads to the establishment of the developmental pathway in the responding tissue
Induction
Controlled cellular growth and at accumulation of byproducts
Proliferation
Change in identical embryonic cells to become distinct, both structurally and functionally
Differentiation
Development of specific tissue structure or differing form due to embryonic cell migration and inductive interactions
Morphogenesis
Attainment of adult function and size due to proliferation differentiation, and morphogenesis
Maturation
Originates directly from Epiblast layer
Ectoderm
Future dermis, muscle, bone
Mesoderm
Layer of cuboidal cells in the embryo
Endoderm
Considered by many to be fourth embryonic layer
Neural crest cells
Prenatal organ that joins pregnant woman and developing embryo
Placenta
Furrowed, Rod shaped thickening in the middle of embryonic disc
Primitive streak
Having potential to proliferate And differentiate into diverse types of connective tissue forming cells
Mesenchyme
Location of future primitive mouth of embryo
Oropharyngeal membrane
Location of future terminal and of embryos and digestive tract
Cloacal membrane
Specialized group of cells differentiates from the ectoderm
Neuroectoderm
Elimination of groove between two adjacent swellings of tissues are processes on embryo surface
Fusion
Mesoderm additionally differentiate and begins to divide into paired cuboidal aggregates of cells
Somites
