39. In which of the following sheet-like epithelia do all cells touch the basement membrane but not all cells reach or border the lumen? Stratified cuboidal as in the duct of a sweat gland Transitional Stratified squamous kerantinizing Stratified squamous non-kerantinizing Pseudostratified columnar 38. As a glandular epithelial cell secretes its product small pieces of the apical cytoplasm of the cell are released as a component of the secretory product. Which of the following correctly applies to this situation? Apocrine Paracrine Merocrine (or eccrine) Endocrine Holocrine

Step 1
We can eliminate stratified cuboidal, stratified squamous keratinizing, and stratified squamous non-keratinizing because they are all stratified epithelia, meaning they have multiple layers of cells, and not all cells touch the basement membrane. Transitional Show more…

Exercise 7 Review & Practice Sheet: Epithelial Tissue Drag and drop the terms on the left to match the appropriate descriptions on the right. transitional goblet cells stratified connective simple squamous simple cuboidal simple columnar basement membrane Epithelium that occurs in a thick layer of cells is epithelium. Cells that secrete mucin are called . The epithelium that lines the stomach and small intestine is epithelium. Epithelium that stretches and relaxes is epithelium. Epithelium that occurs in a single layer of flat cells is epithelium. Epithelium that occurs in the facing layers of serous membranes is epithelium. The tissue deep to epithelium is . Epithelia are attached to a deep layer of connective tissues by a membrane called the .

Select all of the following that are characteristics that apply to epithelial tissues: - cells scattered in a matrix - tightly packed cells - branching extensions - have a basement membrane - excitable - contractile - have a free (apical) surface - named for layering and cell shape - have multiple nuclei - have 1 nucleus - protect, reduce friction, secret and absorb, or allow diffusion - line surfaces and cavities - function in communication
