Question

question 58

what canals connect lacunae together?

canaliculi
perforating (volkmanns) canals
central canals
central (haversian) canals

question 59

secondary ossification centers are characteristic of:

intramembranous ossification.
appositional growth.
endochondral ossification.
mesenchymal ossification.

Explanation:

Question 58 Analysis

Using the Lacunae and Canaliculi knowledge point

• Lacunae are small spaces in bone tissue containing osteocytes.
• Canaliculi are tiny canals connecting lacunae to each other and to the central canal, allowing nutrient distribution.
• Perforating (Volkmann's) canals and central (Haversian) canals house larger blood vessels and nerves but do not directly connect individual lacunae together.

Question 59 Analysis

Using the Endochondral Ossification knowledge point

• Endochondral ossification involves replacing a hyaline cartilage model with bone.
• The primary ossification center develops in the diaphysis (shaft).
• Secondary ossification centers develop in the epiphyses (ends) of long bones, which is a key characteristic of endochondral ossification.
• Intramembranous ossification develops directly from mesenchymal sheets without a cartilage model.

Answer:

Question 58

• canaliculi (Correct answer)
• perforating (Volkmann's) canals
• central canals
• central (Haversian) canals

Question 59

• intramembranous ossification.
• apposition growth.
• endochondral ossification. (Correct answer)
• mesenchymal ossification.
