#1
Which of the following is NOT a function of connective tissues?
Communication
ExplanationConnective tissues do not have a primary function of communication; instead, they provide support, bind tissues, and protect organs.
#2
Which type of connective tissue is primarily composed of cells called chondrocytes?
Cartilage
ExplanationCartilage is primarily composed of chondrocytes, which maintain the extracellular matrix.
#3
What is the primary protein fiber found in connective tissues?
Collagen
ExplanationCollagen is the main protein fiber in connective tissues, providing strength and structural support.
#4
Which connective tissue is responsible for insulation and energy storage in the body?
Adipose tissue
ExplanationAdipose tissue functions to store energy in the form of fat and provides insulation.
#5
Which type of connective tissue provides support and flexibility to structures such as the nose, trachea, and ends of long bones?
Elastic cartilage
ExplanationElastic cartilage provides support and flexibility to structures like the nose, trachea, and ends of long bones due to its elastic fibers.
#6
Where is reticular tissue primarily found in the body?
In lymphoid organs such as the spleen and lymph nodes
ExplanationReticular tissue is mainly found in lymphoid organs, providing structural support for organs like the spleen and lymph nodes.
#7
Where is dense regular connective tissue commonly found in the body?
In tendons and ligaments
ExplanationDense regular connective tissue is commonly found in tendons and ligaments, providing strength and support to these structures.
#8
What is the main function of loose connective tissue?
To cushion and protect organs
ExplanationLoose connective tissue functions to cushion and protect organs while supporting them.
#9
What is the primary function of fibroblasts in connective tissue?
To produce collagen fibers
ExplanationFibroblasts are cells in connective tissue that produce collagen fibers, contributing to the tissue's strength and structure.
#10
Which connective tissue is characterized by a matrix composed of calcium salts and collagen fibers?
Bone
ExplanationBone is a connective tissue with a matrix composed of calcium salts and collagen fibers, providing rigidity and support.
#11
Which connective tissue is responsible for connecting muscle to bone?
Tendon
ExplanationTendons are connective tissues that connect muscles to bones, transmitting the force generated by muscles to the bones.
#12
What is the primary function of elastic fibers in connective tissue?
To provide elasticity and resilience
ExplanationElastic fibers in connective tissue provide elasticity and resilience, allowing tissues to stretch and return to their original shape.
#13
Which type of connective tissue is responsible for producing erythrocytes, leukocytes, and platelets?
Blood
ExplanationBlood is a connective tissue that produces and transports blood cells, including erythrocytes, leukocytes, and platelets.
#14
What is the role of mast cells in connective tissue?
To release histamine and other inflammatory chemicals
ExplanationMast cells in connective tissue release histamine and other inflammatory chemicals in response to injury or irritation.
#15
Which type of connective tissue is found in the stroma of many organs and provides structural support?
Areolar tissue
ExplanationAreolar tissue, found in the stroma of many organs, provides structural support and flexibility to surrounding tissues.
#16
What is the primary function of fibrocartilage in the body?
To provide flexibility and support
ExplanationFibrocartilage provides flexibility and support, especially in areas like intervertebral discs.
#17
Which type of connective tissue is primarily composed of cells called osteoblasts and osteoclasts?
Bone
ExplanationBone tissue is primarily composed of cells called osteoblasts (bone-forming) and osteoclasts (bone-resorbing), maintaining bone structure and homeostasis.
