#1
Which of the following is the most abundant protein in connective tissue?
Collagen
ExplanationCollagen provides structural integrity and support to connective tissue.
#2
What is the main function of adipose tissue?
Storage of fat
ExplanationAdipose tissue primarily stores energy in the form of fat.
#3
Which type of connective tissue is responsible for attaching muscles to bones?
Tendon
ExplanationTendons connect muscles to bones, transmitting the force of muscle contraction.
#4
What is the primary function of elastic cartilage in the body?
Flexibility
ExplanationElastic cartilage provides flexibility and shape to structures like the ear and epiglottis.
#5
What is the primary function of synovial fluid in joints?
Shock absorption
ExplanationSynovial fluid lubricates joints and absorbs shocks, reducing friction and wear.
#6
Which cell type is involved in the immune response within connective tissue?
Mast cells
ExplanationMast cells play a role in immune responses and inflammation within connective tissue.
#7
Which connective tissue type provides strength and flexibility to the skin and blood vessels?
Elastic tissue
ExplanationElastic tissue imparts elasticity and resilience to the skin and blood vessels.
#8
Where can reticular fibers be found in the body?
Spleen and lymph nodes
ExplanationReticular fibers form supportive networks in organs like the spleen and lymph nodes.
#9
What is the primary function of hyaline cartilage?
Shock absorption
ExplanationHyaline cartilage absorbs shock and reduces friction between bones.
#10
Which connective tissue is rich in calcium salts and collagen fibers, providing structural support?
Bone
ExplanationBone tissue provides structural support and mineral storage.
#11
Where can dense regular connective tissue be found in the body?
Tendons and ligaments
ExplanationDense regular connective tissue forms tendons and ligaments, providing strong attachments.
#12
What is the main function of chondrocytes in cartilage?
Maintain the matrix
ExplanationChondrocytes maintain the extracellular matrix of cartilage, essential for its structure and function.
#13
Which cell type is responsible for the synthesis of collagen fibers in connective tissue?
Fibroblasts
ExplanationFibroblasts are key cells in connective tissue that produce collagen fibers.
#14
What is the function of mast cells in connective tissue?
Inflammation and immune response
ExplanationMast cells play a role in inflammatory responses and immune reactions within connective tissue.
#15
Which connective tissue type forms the supporting framework for organs like the spleen and liver?
Reticular tissue
ExplanationReticular tissue forms the framework for soft organs like the spleen and liver.
#16
In which layer of the skin can dense irregular connective tissue be found?
Dermis
ExplanationDense irregular connective tissue is found in the dermis layer of the skin, providing strength and support.
#17
Which connective tissue type is responsible for insulation and energy storage?
Adipose tissue
ExplanationAdipose tissue provides insulation, cushioning, and stores energy in the form of fat.
#18
Which connective tissue type is involved in the repair of damaged tissues through scar formation?
Dense irregular connective tissue
ExplanationDense irregular connective tissue helps in tissue repair by forming scar tissue, providing strength and support.
