Final answer:
To label a diagram of compact bone, one must know that the osteon is the basic unit consisting of concentric lamellae surrounding a central canal, with lacunae housing osteocytes and canaliculi allowing for nutrient and waste exchange.
Step-by-step explanation:
Labeling the Diagram of Compact Bone The student has been asked to label the following illustration using the terms provided: a. lamella b. Osteon c. Canaliculi d. central canal e. lacuna (for osteocyte). In response to this request, the following definitions and locations can be given based on the description of compact bone structure:
- Lamella (å): These are the concentric rings of calcified matrix within an osteon that surround the central canal. They give the bone its strength and resilience.
- Osteon (or Haversian system) (b): This is the basic cylindrical unit of compact bone. It includes the central canal, surrounded by lamellae.
- Canaliculi (c): These are tiny channels that connect lacunae to each other and the central canal, allowing nutrients and wastes to be transferred between osteocytes and blood vessels.
- Central canal (d) (or Haversian canal): This is found at the center of each osteon and contains blood vessels, nerves, and lymphatic vessels.
- Lacuna (e) (for osteocyte): This is a small space containing an osteocyte between the lamellae. It is connected to other lacunae and the central canal by the canaliculi.
By understanding these terms and their locations, the student can correctly identify and label these structures on an illustration of compact bone.
