(7) Classify the tissue type Areolar CT
(8) Identify the cell indicated by the arrow fibroblast

Question

BlackTom AI · Accepted Answer

This item presents two dropdowns to fill in: a tissue-type classification and a cell type identification.

First dropdown (tissue type): The tissue that shows a loose arrangement of fibers, a clear gel-like ground substance, and numerous spaces with notable vascularization is Areolar connective tissue. Key features to anchor this choice include a loose packing of collagen and elastic fibers, a relatively abundant extracellular matrix, and cells such as fibroblasts scattered within the matrix. Were you to consider other connective tissues, you would expect denser fiber arrangements (dense connective tissue), specialized matrices (cartilage, bone), or adipose tissue with large lipid droplets; those do not match the observed loose, airy framework characteristic of Areolar CT.

Second dropdown (cell indicated by the arrow): The prominent, elongated cell type typically responsible for producing and maintaining the extracellular matrix in connective tissue is the fibroblast. Fibroblasts have an oval or spindled shape with an active cytoplasm, and they are the primary source of collagen, elastic fibers, and ground substance in Areolar CT. Incorrect contenders would include fibrocytes (the less active, mature form found in the matrix), adipocytes (fat-storing cells with large lipid droplets), macrophages (immune cells with phagocytic roles), or mast cells (involved in inflammatory responses). Each of these has distinct morphology or function that does not align with a cell actively synthesizing and maintaining the loose connective tissue matrix in the described slide.

To summarize the reasoning for each dropdown is: the tissue type matches Areolar connective tissue with its loose, hydrated matrix and abundant spaces; the cell indicated by the arrow matches a fibroblast, the main matrix-synthesizing cell in connective tissue. The other potential tissue types and cell types would present with noticeably different structural or functional hallmarks, making them incompatible with the given description.
