Penumbra

Necrotic core

Ischemic zone

Scar tissue

Verified step by step guidance

Step 1: Begin by understanding the key terms in the problem. 'Ischemic tissue' refers to tissue that is deprived of adequate blood supply, leading to oxygen deficiency. 'Infarcted tissue' is tissue that has already died due to prolonged ischemia.

Step 2: Recognize the concept of 'penumbra' in medical terminology. The penumbra is the area of ischemic tissue surrounding the infarcted core that is still viable and can potentially recover if blood flow is restored promptly.

Step 3: Differentiate between the options provided. 'Necrotic core' refers to the central area of dead tissue, 'ischemic zone' is a general term for tissue with reduced blood flow, and 'scar tissue' forms after healing but is not salvageable.

Step 4: Focus on the term 'potentially salvageable with timely intervention.' This phrase is key to identifying the penumbra, as it specifically describes tissue that can recover if treated quickly.

Step 5: Conclude that the correct term for the area of ischemic tissue surrounding infarcted tissue and potentially salvageable is 'penumbra,' based on its definition and the context provided.
