#1
Which of the following is a characteristic of epithelial tissue?
Avascular but innervated
ExplanationEpithelial tissue lacks blood vessels but is supplied with nerve fibers.
#2
What is the primary function of transitional epithelium in the urinary system?
Stretch and recoil
ExplanationTransitional epithelium allows the urinary system to stretch and recoil during filling and emptying.
#3
Which of the following is a characteristic of simple cuboidal epithelium?
Single layer of cube-shaped cells
ExplanationSimple cuboidal epithelium is composed of a single layer of cube-shaped cells.
#4
What is the primary function of stratified columnar epithelium?
Protection
ExplanationStratified columnar epithelium provides protection, typically in areas of transition.
#5
Which type of epithelial tissue is found in the lining of the stomach?
Simple columnar epithelium
ExplanationSimple columnar epithelium lines the stomach, facilitating absorption and secretion.
#6
What is the primary function of simple squamous epithelium?
Filtration
ExplanationSimple squamous epithelium is thin and allows for the filtration of substances.
#7
Which of the following epithelial tissues is found in the urinary bladder?
Transitional epithelium
ExplanationTransitional epithelium allows for stretching and recoiling, suitable for the urinary bladder.
#8
Where is pseudostratified columnar epithelium commonly found in the body?
Bronchi of the respiratory tract
ExplanationPseudostratified columnar epithelium lines the respiratory passages, including the bronchi.
#9
What is the primary function of goblet cells in epithelial tissues?
Secretion of mucus
ExplanationGoblet cells produce and secrete mucus, aiding in lubrication and protection.
#10
What distinguishes stratified cuboidal epithelium from simple cuboidal epithelium?
Number of layers
ExplanationStratified cuboidal epithelium consists of multiple layers, unlike simple cuboidal epithelium.
#11
What is the primary function of cilia in epithelial cells?
Movement of mucus
ExplanationCilia on epithelial cells facilitate the movement of mucus along surfaces.
#12
Which type of epithelial tissue is best suited for areas subjected to friction?
Stratified squamous epithelium
ExplanationStratified squamous epithelium provides protection against mechanical stress and friction.
#13
Which of the following is a characteristic feature of stratified squamous epithelium?
Protective function
ExplanationStratified squamous epithelium serves a protective role due to its multiple layers.
#14
In which organ would you find simple columnar epithelium with microvilli?
Small intestine
ExplanationSimple columnar epithelium with microvilli is found in the small intestine, aiding in absorption.
#15
What is the primary function of microvilli in epithelial cells?
Absorption
ExplanationMicrovilli increase the surface area of epithelial cells, enhancing absorption.
