#1
Which protein is the primary component of fibrous connective tissue?
Collagen
ExplanationCollagen is the main protein providing strength and structure to fibrous connective tissue.
#2
What is the function of fibrous connective tissue in the body?
To provide support and structure
ExplanationFibrous connective tissue supports and maintains the structural integrity of various body parts.
#3
Which of the following is NOT a type of fibrous connective tissue?
Adipose tissue
ExplanationAdipose tissue is a type of loose connective tissue primarily involved in fat storage.
#4
Where can dense regular connective tissue typically be found in the body?
In tendons and ligaments
ExplanationDense regular connective tissue forms tendons and ligaments, providing strong attachments between muscles and bones.
#5
What is the main function of elastic fibers in fibrous connective tissue?
To allow for elasticity and recoil
ExplanationElastic fibers provide elasticity, allowing tissues to stretch and recoil to their original shape.
#6
Which vitamin is essential for the synthesis of collagen?
Vitamin C
ExplanationVitamin C is crucial for the enzymatic reactions involved in collagen synthesis.
#7
Which type of connective tissue is found in the umbilical cord?
Mucous connective tissue
ExplanationMucous connective tissue, also known as Wharton's jelly, provides structural support in the umbilical cord.
#8
Which of the following is a characteristic feature of loose connective tissue?
Sparse arrangement of cells and fibers
ExplanationLoose connective tissue has a sparse arrangement of cells and fibers, allowing for flexibility and cushioning.
#9
Where is fibrous connective tissue not commonly found in the human body?
Cartilage
ExplanationFibrous connective tissue is not commonly found in cartilage, which consists mainly of cartilage cells and extracellular matrix.
#10
Which cell type is responsible for producing the extracellular matrix of fibrous connective tissue?
Fibroblast
ExplanationFibroblasts are cells that synthesize and maintain the extracellular matrix of fibrous connective tissue.
#11
What is the main difference between loose connective tissue and dense connective tissue?
The arrangement of collagen fibers
ExplanationLoose connective tissue has a more scattered arrangement of collagen fibers, while dense connective tissue has a denser and more organized arrangement.
#12
What is the primary function of reticular fibers in fibrous connective tissue?
To support immune cells
ExplanationReticular fibers form a supportive network for immune cells in lymphoid organs and bone marrow.
