Question

anatomy of a bone - coloring
epiphysis (a) - at the ends of the bone, do not color. the epiphysis has a thin layer of compact bone, while internally the bone is cancellous. the epiphysis is capped with articular cartilage.
epiphyseal line (j) - purple. the epiphyseal line or disk is also called the growth plate, it is found on both ends of the long bone.
diaphysis (shaft) (b) - do not color. the diaphysis is the shaft of the long bone. it has compact bone with a central cavity.
articular cartilage (c) - green. the articular cartilage is found on the ends of long bones. it is smooth, slippery, and bloodless. color both ends.
periosteum (d) - dark blue. periosteum is a vascular, sensitive life support covering for bone. it provides nutrient - rich blood for bone cells and is a source of bone - developing cells during growth or after a fracture. color both sides, it is the outermost layer.
cancellous (spongy) bone (e) and marrow (e) - red. the cancellous bone is found mainly within the epiphysis and has a textured appearance where it contains red marrow. color both ends.
compact bone (f) - pink. the compact bone is a dense bone found in the diaphysis. its repeated pattern is arranged in concentric layers of solid bone tissue. the compact bone can be seen as the layer just underneath the periosteum, color both ends.
medullary cavity (g), yellow marrow (g) - yellow. the medullar cavity of the diaphysis serves to lighten bone weight and provide space for marrow. yellow marrow is associated with fat.
endosteum (h) - light blue. this tissue lines the medullary cavity of bone.

1. where do you find yellow marrow (be specific)?
2. what type of bone is arranged in concentric layers?
3. where do you find red marrow?
4. what is the end of the bone called?
5. spongy bone is also called
6. what cushions the ends of bones at their joints? _ bone.

Explanation:

1. The text mentions that yellow marrow is found in the medullary cavity of the diaphysis.
2. Compact bone has its pattern arranged in concentric layers as described in the text.
3. Red marrow is found within the cancellous (spongy) bone mainly in the epiphysis.
4. The end of the bone is called the epiphysis.
5. Spongy bone is also called cancellous bone.
6. Articular cartilage cushions the ends of bones at their joints.

Answer:

1. Medullary cavity of the diaphysis
2. Compact bone
3. Cancellous (spongy) bone in the epiphysis
4. Epiphysis
5. Cancellous bone
6. Articular cartilage
