Match the appropriate name with the structure in the figure.
5. Osteocyte

Guida verificata passo dopo passo

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 osteocyte. Osteocytes are mature bone cells that maintain the bone matrix. In the image, they are located within small spaces called lacunae, which are shown as purple cells embedded in the bone matrix.

Step 3: Match the label to the osteocyte. Look for the label pointing to the purple cell within the lacunae. In this image, label 'd' points to the osteocyte.

Step 4: Confirm by checking other labels: 'a' points to the lamellae (concentric rings of bone matrix), 'b' points to the canaliculi (tiny canals connecting osteocytes), 'c' points to the central canal (Haversian canal), and 'e' points to the lacunae (spaces housing osteocytes).

Step 5: Conclude that the structure labeled 'd' corresponds to the osteocyte, as it is the bone cell embedded within the lacunae.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Osteocyte

Osteocytes are mature bone cells embedded within the bone matrix. They reside in small spaces called lacunae and maintain bone tissue by regulating mineral content. Osteocytes communicate through tiny channels called canaliculi, which allow nutrient and waste exchange.

Osteocytes

Lacunae

Lacunae are small cavities within the bone matrix that house osteocytes. These spaces protect the osteocytes and are interconnected by canaliculi, facilitating cellular communication and nutrient transfer essential for bone maintenance.

Canaliculi

Canaliculi are microscopic channels that connect lacunae in bone tissue. They enable osteocytes to exchange nutrients, waste, and chemical signals, maintaining the viability of bone cells despite the dense mineralized matrix.
