In skin, the cells of the epidermis connect to the basal lamina through cellular junctions known as hemidesmosomes. Select the cytoskeletal element that helps maintain the integrity of this connection.
A)intermediate filaments
B)microtubules
C)microfilaments
D)both intermediate filaments and microfilaments

Question

Quizplus · Accepted Answer

Hemidesmosomes are cellular junctions that anchor the cells of the epidermis to the underlying basal lamina. These junctions are crucial for maintaining the integrity of the skin. Intermediate filaments are a type of cytoskeletal element that helps to anchor hemidesmosomes to the cells of the epidermis. Therefore, choice A is the best answer. Microtubules and microfilaments do not play a significant role in maintaining the integrity of hemidesmosomes.
