Which is avascular (lacks blood vessels)?

Question

BlackTom AI · Accepted Answer

Let’s examine what avascular means in the context of tissue types and their vascular supply.
Option 1: nervous tissue — Nervous tissue has a rich blood supply through capillaries and supportive vasculature to meet high metabolic demands; therefore it is not avascular.
Option 2: all of the choices are correct — Since not all listed tissues lack blood vessels, this blanket statement is inaccurate.
Option 3: epithelial tissue — Epithelial tissue is typically avascular; it lacks blood vessels within the epithelium itself and relies on diffusion from the underlying connective tissue for nutrients and gas exchange.
Option 4: muscle tissue — Muscle tissue, including skeletal and cardiac muscle, is highly vascularized to support contraction and metabolic needs, so it is not avascular.
In summary, the statement that best fits the definition of avascular among the options is that epithelial tissue lacks blood vessels, whereas nervous, connective-adjacent, and muscle tissues generally contain a blood supply.
