marrow cavity
choose
periosteum
choose
spongy bone
choose
distal epiphysis
choose
articular cartilage
choose

Explanation:

1. Marrow cavity: This is the central hollow space in the diaphysis (shaft) of the long bone, which holds bone marrow.
2. Periosteum: A tough, fibrous membrane that covers the outer surface of the bone (excluding the articular ends).
3. Spongy Bone: Found in the epiphyses, this is a porous, lattice-like bone tissue.
4. Distal Epiphysis: The rounded end of the long bone that is farthest from the body's trunk.
5. Articular Cartilage: Smooth, white tissue that covers the ends of bones where they form joints, reducing friction.

Answer:

• Marrow cavity: G
• Periosteum: E
• Spongy Bone: I
• Distal Epiphysis: C
• Articular Cartilage: K
