Multiple Choice

Which of the following is an accurate description of the pseudocoelom?

A body cavity that is completely lined by mesodermal tissue

Verified step by step guidance

Understand the term 'pseudocoelom': In anatomy, a pseudocoelom is a type of body cavity that is not completely lined by mesodermal tissue. This is a key characteristic that differentiates it from a true coelom.

Identify the options: The problem provides several descriptions of body cavities. We need to determine which one accurately describes a pseudocoelom.

Analyze the first option: 'A body cavity that is not fully lined by mesodermal tissue' matches the definition of a pseudocoelom, as it indicates partial mesodermal lining.

Evaluate the second option: 'A body cavity that is lined by ectodermal tissue' does not describe a pseudocoelom, as the lining involves mesodermal tissue, not ectodermal.

Consider the remaining options: 'A solid body without any cavity' and 'A body cavity that is completely lined by mesodermal tissue' do not fit the definition of a pseudocoelom. The former describes an acoelomate, and the latter describes a true coelom.
