검증된 단계별 안내

Step 1: Understand the structure of compact bone shown in the image. The image depicts an osteon, which is the fundamental functional unit of compact bone.

Step 2: Identify the lacunae in the osteon. Lacunae are small spaces or cavities within the bone matrix that house osteocytes (bone cells). In the image, these are the small purple spots surrounded by yellowish bone matrix.

Step 3: Locate the label that points to these small cavities. In the image, label 'd' points directly to these small spaces containing the purple osteocytes.

Step 4: Confirm that label 'd' corresponds to the lacunae, as lacunae are the spaces where osteocytes reside within the bone matrix.

Step 5: Conclude that the structure labeled 'd' in the figure is the lacuna.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Lacuna

A lacuna is a small cavity or space within the bone matrix that houses an osteocyte, the mature bone cell. These lacunae are distributed between the concentric lamellae in compact bone and are essential for maintaining bone tissue.

Osteon Structure

The osteon, or Haversian system, is the fundamental functional unit of compact bone. It consists of concentric lamellae arranged around a central canal containing blood vessels and nerves, facilitating nutrient and waste exchange.

Canaliculi

Canaliculi are tiny channels that radiate from the lacunae, connecting osteocytes to each other and to the central canal. They allow for communication and nutrient transfer between bone cells, crucial for bone health and maintenance.
