Is located below the stratum germinativum b. Consists of fibrous connective tissue which are compactly arranged c. Consists of loosely arranged connective tissue and blood vessels d. Is where numerous glands are locatedWhat are the pathways through which a neural tube defect can occur? Select one or more: V A. Failure of initiation of neural tube closure V B. Failure to fuse the elevated neural folds V C. Abnormalities in adhesion of surface ectodermal cells V D. Altered differentiation of neuromesodermal progenitors at the sacral level

- Which statement about transdermal drugs is true? a. For maximum effectiveness, the skin should not be cleansed with soap once it has been exposed to a transdermal drug. b. Transdermal drugs are preferred because they exert only a local effect. c. For maximum effectiveness, transdermal patches should be reapplied to the same location when reapplied. d. Transdermal drugs provide more consistent blood levels than oral and injection forms.Which of the following is an illustration of permissive interaction? The epidermis signals the underlying dermis to create condensations and the dermal condensations then signal the epidermis to form specific cutaneous structures. Wing epidermal epithelium produces wing feather when exposed to wing dermal mesenchyme but will produce scales and claw when exposed to foot dermal mesenchyme. When implanted in the newt embryo, the frog oral ectoderm can only differentiate into frog derivatives and will not differentiate into newt derivatives. D An inducing signal from the optic vesicle is necessary for new gene expression in the lens ectoderm. E) Contact with the appropriate extracellular matrix is sufficient for cells to express differentiation-specific genes.Which of the following is a true statement? (Check all that apply) A The epidermis forms from the ectodermal domain that is not exposed to BMP inhibitors. B The epidermal stem cell divides symmetrically and one of the daughter-cells goes on to differentiate into a keratinocyte. C) Epidermal cells move upward as they become more and more differentiated. D After the division of the basal cell, the daughter-cell that expresses Notch remains a stem cell. E The integrin-laminin interaction prevents the basal cell from differentiating. F The basal cell divides parallel to its apical-basal axis. G Cells found in the lower layers of the developing skin are more differentiated than the ones found in the upper layers. H p63 is a proliferation factor while Jagged is the true differentiation signal for keratinocytes. I Jagged is a proliferation signal while p63 is the true differentiation factor for keratinocytes. Epidermal signals like Fgf7, FGF10 and TGF-alpha promote the differentiation of the…
