Question

the layers of bone tissue immediately deep to the periosteum are:

trabeculae.
lacunae.
concentric lamellae.
circumferential lamellae.

question 22

bones with a diaphysis and epiphyses are classified as:

flat bones.
irregular bones.
long bones.
short bones.

Explanation:

Analyze the first question on bone tissue layers

The first question asks: "The layers of bone tissue immediately deep to the periosteum are:"

• The periosteum is the outer fibrous membrane covering the surface of bones.
• Immediately deep to the periosteum, wrapping around the entire outer circumference of the diaphysis of a long bone, are the outer circumferential lamellae.
• Concentric lamellae make up the individual osteons deeper within the compact bone.
• Lacunae are the small spaces containing osteocytes.
• Trabeculae are the branching bony plates found in spongy bone, deep within the bone.

Therefore, the correct option is "circumferential lamellae."

Analyze the second question on bone classification

The second question (Question 22) asks: "Bones with a diaphysis and epiphyses are classified as:"

• This question relates to Bone Classification and Long Bone Anatomy.
• A typical long bone consists of a central shaft called the diaphysis and two expanded ends called the epiphyses.
• Flat bones, irregular bones, and short bones do not have a distinct diaphysis and epiphyses structure.

Therefore, the correct option is "long bones."

Answer:

Question 1

• trabeculae.
• lacunae.
• concentric lamellae.
• circumferential lamellae. (Correct answer)

Question 2

• flat bones.
• irregular bones.
• long bones. (Correct answer)
• short bones.
