#1
Which of the following is not a component of connective tissue?
Neurons
ExplanationNeurons are not a component; connective tissue mainly consists of cells, fibers, and ground substance.
#2
Which protein provides tensile strength to connective tissues?
Collagen
ExplanationCollagen provides tensile strength, forming the structural framework of connective tissues.
#3
Which of the following is not a function of connective tissue?
Initiating and conducting nerve impulses
ExplanationInitiating and conducting nerve impulses is a function of nervous tissue, not connective tissue.
#4
What is the function of adipose tissue in the body?
Storing energy
ExplanationAdipose tissue stores energy in the form of triglycerides, serving as a fuel reserve.
#5
What is the primary cell type responsible for producing collagen fibers?
Fibroblasts
ExplanationFibroblasts are the main cells synthesizing collagen fibers in connective tissues.
#6
Which connective tissue type contains a fluid matrix called plasma?
Blood
ExplanationBlood contains plasma, a fluid matrix, and various cells and proteins.
#7
Which connective tissue type is found in the external ear and epiglottis?
Elastic cartilage
ExplanationElastic cartilage, with elastic fibers, provides flexibility and support in structures like the external ear.
#8
Which vitamin is essential for the synthesis of collagen?
Vitamin C
ExplanationVitamin C is crucial for collagen synthesis, facilitating the conversion of proline to hydroxyproline.
#9
Which glandular connective tissue type stores lipids for energy?
Adipose tissue
ExplanationAdipose tissue stores lipids for energy storage, insulation, and cushioning.
#10
Which type of connective tissue forms tendons and ligaments?
Dense regular connective tissue
ExplanationDense regular connective tissue forms tendons and ligaments, providing strong, organized support.
#11
What is the role of ground substance in connective tissue?
Binds cells and fibers together
ExplanationGround substance binds cells and fibers together, providing support and facilitating nutrient exchange.
#12
What type of connective tissue is the stroma of lymphoid organs primarily composed of?
Reticular tissue
ExplanationReticular tissue forms the stroma of lymphoid organs, providing structural support.
#13
Which glycoprotein is responsible for binding cells to the extracellular matrix in connective tissue?
Fibronectin
ExplanationFibronectin is a glycoprotein facilitating cell adhesion to the extracellular matrix in connective tissue.
#14
What is the most abundant protein in the human body?
Collagen
ExplanationCollagen is the most abundant protein in the human body, providing structural support.
#15
Which connective tissue component provides resistance to compression in cartilage?
Chondroitin sulfate
ExplanationChondroitin sulfate provides resistance to compression in cartilage, maintaining its integrity.
