Explanation:

To fill in the "Anatomy of a Long Bone – Notes" table, we use knowledge of bone anatomy (from the subfield of Biology, specifically Anatomy/Physiology):

Articular Cartilage

• Found: At the ends of long bones (covering the epiphyses).
• Protects from: Friction (during movement) and damage (to the underlying bone).
• Does it repair easily?: No (it has limited blood supply, so repair is slow/rare).
• Loss is known as: Osteoarthritis (or articular cartilage degeneration).

Red Marrow

• Found inside the: Spongy bone (and central cavities of some bones, like the sternum).
• Soft tissue full of: Stem cells (hematopoietic stem cells) that produce:
• Red blood cells (erythrocytes),
• White blood cells (leukocytes),
• Platelets (thrombocytes).

Periosteum

• A membrane made of: Dense connective tissue (collagen) that covers the outer surface of the bone (except at joints).
• Vascular: filled with: Blood vessels (to nourish the bone).
• Full of: Osteoblasts/osteoclasts (cells for bone growth/remodeling) that allow a bone to grow in length and width (or “diameter”/“thickness”).

Spongy Bone

• Type of bone found in the: Ends (epiphyses) of our bones.
• Weight: Lightens (reduces) weight (to make movement easier).
• Has: Spaces (trabecular cavities) in it filled with red marrow.

Compact Bone

• Has: Few (or no) spaces (dense structure).
• Much: Harder (or denser) than spongy bone.
• Makes up the: Shaft (diaphysis) of the bone.

These answers align with standard anatomical descriptions of long bones.
