Q1 QUESTION 1 OF 90
reticular fiber
CORRECT ANSWER
fine fibrous protein, made of collagen subunits, which cross-link to form supporting "nets" within connective tissue
RATIONALE
Reticular fibers, composed of type III collagen, provide structural support by forming a delicate network that stabilizes the
architecture of organs and tissues, particularly within lymphatic and hematopoietic systems. Their ability to create these supportive
"nets" is critical for maintaining tissue integrity and facilitating cellular organization.
Q2 QUESTION 2 OF 90
reticular tissue
CORRECT ANSWER
type of loose connective tissue that provides a supportive framework to soft organs, such as lymphatic tissue, spleen, and the
liver
RATIONALE
Reticular tissue consists of a network of reticular fibers that forms a soft, supportive framework essential for the structure and function
of organs like the spleen and lymph nodes, facilitating the organization and support of cellular components. Its loose connective
nature allows for flexibility while maintaining structural integrity in soft organs.
Q3 QUESTION 3 OF 90
hyaline cartilage
CORRECT ANSWER
most common type of cartilage, smooth and made of short collagen fibers embedded in a chondroitin sulfate ground substance
Page 2
, RATIONALE
Hyaline cartilage, characterized by its smooth surface and high collagen fiber density within a chondroitin sulfate matrix, provides
structural support and facilitates smooth joint movement, making it the predominant type of cartilage in the body. This composition is
essential for maintaining joint integrity and function, particularly in articular surfaces and the respiratory tract.
Q4 QUESTION 4 OF 90
mesenchyme
CORRECT ANSWER
embryonic tissue from which connective tissue cells derive
RATIONALE
Mesenchyme is a type of embryonic tissue characterized by loosely organized cells that can differentiate into various connective
tissues, including bone, cartilage, and blood. This property is fundamental to the development of the skeletal and circulatory systems
in vertebrates.
Q5 QUESTION 5 OF 90
supportive connective tissue
CORRECT ANSWER
type of connective tissue that provides strength to the body and protects soft tissue
RATIONALE
Supportive connective tissue, such as bone and cartilage, functions to provide structural integrity and mechanical support while also
safeguarding softer tissues, thereby playing a critical role in the framework of the body. Its composition, rich in collagen and other
fibers, enhances resistance to tensile and compressive forces.
Q6 QUESTION 6 OF 90
pseudostratified columnar epithelium
CORRECT ANSWER
tissue that consists of a single layer of irregularly shaped and sized cells that give the appearance of multiple layers; found in
ducts of certain glands and the upper respiratory tract
