Which tissue would line the uterine (fallopian) tubes?
ciliated simple columnar epithelium
smooth MT
simple cuboidal epithelium
stratified squamous epithelium
The Correct Answer is A
A. ciliated simple columnar epithelium: The uterine (fallopian) tubes are lined with ciliated simple columnar epithelium. The cilia help move the ovum from the ovary toward the uterus, while secretory cells provide nourishment for the ovum and early embryo.
B. smooth MT: Smooth muscle tissue is present in the walls of the uterine tubes to aid peristaltic movement, but it does not line the lumen. The lining is provided by epithelial tissue, not muscle tissue.
C. simple cuboidal epithelium: Simple cuboidal cells are commonly found in glandular tissues and kidney tubules, where they function in secretion and absorption. They do not have the cilia required for egg transport in the uterine tubes.
D. stratified squamous epithelium: Stratified squamous epithelium is specialized for protection in areas exposed to friction, such as the skin and vaginal canal. It is not suitable for the transport and nourishment functions of the uterine tubes.

Correct Answer is C
Explanation
A. Stratified epithelia are tall, narrow cells:Stratified epithelia are defined by having multiple layers of cells, not by cell shape. While some stratified cells can be tall (columnar), they can also be cuboidal or squamous in shape, depending on the location.
B. Pseudostratified epithelia consist of at least two layers of cells stacked on top of one another:Pseudostratified epithelium appears multilayered because nuclei are at different levels, but all cells contact the basement membrane. It is not composed of multiple layers.
C. Stratified epithelia are present where protection from abrasion is important:Stratified epithelia provide multiple layers of cells, offering significant protection against mechanical stress, friction, and abrasion. This is why they are found in areas such as the skin, mouth, and esophagus.
D. Simple epithelia form impermeable barriers:Simple epithelia are composed of a single cell layer and allow for selective diffusion, absorption, or secretion rather than forming completely impermeable barriers.
Correct Answer is B
Explanation
A. collagen, elastin, and reticular fibers:These are the main types of fibers found in connective tissue, providing strength, elasticity, and support, but they do not represent all three main components.
B. ground substance, fibers, and cells:Connective tissue is composed of cells (such as fibroblasts, macrophages, and adipocytes), fibers (collagen, elastin, reticular), and ground substance (a gel-like material that fills the extracellular space). These three components work together to provide support, strength, and a medium for nutrient and waste exchange.
C. alveoli, fibrous capsule, and secretory cells:These structures are specific to glands or organs like the lungs, not general components of connective tissue.
D. fibroblasts, chondroblasts, and osteoblasts:These are specific types of connective tissue cells responsible for producing matrix in different connective tissues, but they do not account for fibers and ground substance, so they are not the three main components
