Capitolo 4, Problema 2
An epithelium that has several layers, with an apical layer of flattened cells, is called (choose all that apply):
a. Ciliated
b. Columnar
c. Stratified
d. Simple
e. Squamous
Guida verificata passo dopo passo1
Step 1: Understand the terms related to epithelial tissue structure. 'Simple' epithelium means a single layer of cells, while 'stratified' means multiple layers of cells.
Step 2: Identify the shape of the cells in the apical (top) layer. 'Squamous' refers to flattened, scale-like cells; 'columnar' refers to tall, column-shaped cells; 'ciliated' refers to cells that have hair-like projections called cilia on their surface.
Step 3: Since the problem states the epithelium has several layers, eliminate 'simple' because it only has one layer.
Step 4: Since the apical layer consists of flattened cells, this corresponds to 'squamous' cell shape.
Step 5: Combine the correct descriptors: an epithelium with several layers and a top layer of flattened cells is called 'stratified squamous epithelium'. 'Ciliated' and 'columnar' do not apply here based on the description.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Stratified Epithelium
Stratified epithelium consists of multiple layers of cells stacked on top of each other, providing protection against abrasion and stress. The presence of several layers distinguishes it from simple epithelium, which has only one layer.

Stratified Squamous Epithelia
Squamous Cells
Squamous cells are flat, thin cells that form the apical layer in certain epithelia. When the surface layer of an epithelium is composed of these flattened cells, it is described as squamous, which aids in diffusion and protection.

Simple vs. Stratified Epithelium
Simple epithelium has a single cell layer, while stratified epithelium has multiple layers. This distinction is crucial for identifying tissue types, as simple epithelia are involved in absorption and filtration, whereas stratified epithelia primarily protect underlying tissues.
