Pre-Lab Questions Select the correct answer for each of the following questions:Fibrous joints are structural types containinga. cartilage
b. dense fibrous connective tissue.
c. synovial membranes.
d. synovial fluid.
Introduction :
The connection between two bones is termed as joint. The fibrous joint abundantly contains collagen. These joints are immovable, thus are called fixed joints. The fibrous joint is present between skull bones and called suture. There is no space or cavity in fibrous joint.
Answer to Problem 1PL
Correct answer :
The correct answer is option (b) dense fibrous connective tissue.
Explanation of Solution
Explanation/justification for the correct answer :
Option (b) dense fibrous connective tissue. The fibrous joints are immovable consisting of dense fibrous connective tissue. The immobile nature of such a joint is due to no space or cavity between bones. The fibrous joints are gomphoses, syndesmoses, and sutures. So, the correct answer is option (b).
Explanation for incorrect answer :
Option (a) cartilage. The cartilage is flexible and soft connective tissue present in knees, ankles, and elbow. Hyaline cartilage is present at most of the joints. Cartilage is present only in the cartilaginous joint. So, this is an incorrect option.
Option (c) synovial membrane. The synovial membrane is present in the synovial joint and acts as a shock absorber. The inner surface of the synovial joint is lined by synovial membrane. So, this is an incorrect answer.
Option (d)synovial fluid. The synovia or synovial fluid is secreted by the synovial membrane. This fluid acts as a lubricant, nourisher and shock absorber for bones. It reduces the friction between cartilages. So, this is an incorrect answer.
