Quiz in Histology: Connective Tissues
1. Which component of bone impedes the distribution of nutrients and oxygen to osteocytes?
A. ECM
B. Canaliculi
C. Periosteum
D. Cell processes
E. Haversian canals
2. The major lubricant for diarthrotic joints is synthesized by cells located in which joint structure?
A. Nucleus pulposus
B. Synovial membrane
C. Articular cartilage
D. Annulus fibrosus
E. Fibrous capsule
3. A 42 year old woman , who has been a type 1 diabetic for 30 years, falls when she trips over the vacuum
cleaner hose. She tried to break her fall by placing her hand out to save herself and in the process her wrist was
forced backward, breaking her radius near the wrist. Which of the following is produced in the first step in healing
this bone injury?
A. Osteoid
B. Hematoma
C. Bony callus
D. Fibrocartilage
E. Compact bone
4. Which of the following most accurately describes compact bone?
A. Predominant bone type in the epiphyses of adult long bones
B. Also known as cancellous bone
C. Characterized by the presence of osteons
D. Lines the medullary (marrow) cavity
E. Forms the diploe in cranial bones
5. A 46-year-old woman presents with pain in the left leg that worsens on weight bearing. An X-ray shows
demineralization, and a bone biopsy decalcified with EDTA shows reduction in bone quantity. The patient had
undergone menopause at age 45 without estrogen replacement. She reports long-standing diarrhea. In addition,
laboratory tests show low levels of vitamin D, calcium, and phosphorus, and elevated alkaline phosphatase. A
second bone biopsy was taken but not decalcified, which showed extensive deposition of uncalcified osteoid on
all the bone surfaces. On the basis of these data, the best diagnosis would be which of the following?
A. Osteoporosis
B. Scurvy
C. Osteomalacia
D. Rickets
E. Hypoparathyroidism
6. What distinguishes cartilage from most other connective tissues?
A. Its extracellular matrix is rich in collagen.
B. Its predominant cell type is a mesenchymal derivative.
C. Its predominant cell type secretes both fibers and proteoglycans.
