Question

a(n) ______ is a broad, tendinous sheet.
interstitium
aponeurosis
tympanum
fasciae
retinaculum

Explanation:

An aponeurosis is a flat, tendinous sheet that serves to attach muscles to other structures or to other muscles. It is a type of connective - tissue structure. The other options do not match the description of a broad, tendinous sheet. Interstitium is the space between cells, tympanum is related to the eardrum, fasciae are connective - tissue layers but not specifically tendinous sheets like aponeurosis, and retinaculum is a band of connective tissue that holds structures in place.

Answer:

B. aponeurosis
