Question

question 7 (1 point)
the periosteum is secured to the underlying bone by dense connective tissue call
volkmanns canals
a bony matrix with hyaline cartilage
perforating (sharpeys) fibers
the struts of bone known as spicules
question 8 (1 point)
the canal that runs through the core of each osteon (the haversian canal) is the site
cartilage and interstitial lamellae
adipose tissue and nerve fibers
yellow marrow and spicules
blood vessels and nerve fibers

Explanation:

• For Question 7: Periosteum is secured to bone by perforating (Sharpey's) fibers. Volkmann's canals connect Haversian canals. Bony matrix with hyaline cartilage is related to growth. Spicules are part of spongy bone structure.
• For Question 8: Haversian canal contains blood vessels and nerve fibers. Cartilage and interstitial lamellae are not in Haversian canal. Adipose tissue (in yellow marrow) and yellow marrow itself are not in Haversian canal.

Answer:

Question 7: C. perforating (Sharpey's) fibers
Question 8: D. blood vessels and nerve fibers
