The correct answer is (c). The correct statement regarding epithelia is that
stratified epithelia
Which of the following is a correct statement about a simple epithelium?
A layer of simple epithelium is only one cell thick, so its cells rest directly on the thin, three-layered basement membrane. Simple epithelium is often found lining absorptive body cavities or tubes. Hence, the correct option is (a),
all cells touch the basement membrane
.
What is true about epithelia?
Epithelial tissues are
widespread throughout the body
. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. … Epithelial cells may be squamous, cuboidal, or columnar in shape and may be arranged in single or multiple layers.
Which statements describe epithelial tissue?
Which statements correctly describe epithelial tissue?
It is richly innervated, it lacks blood vessels, it has a high regeneration capacity
. Of the four types of the body membranes, the two principal types of internal membranes are ” ” and ” ” membranes.
What are epithelia?
Epithelia are
continuous sheets of cells (one or more layers thick) that cover the exterior surfaces of the body, line internal closed cavities and body tubes that communicate with
the outside environment (the alimentary, respiratory and genitourinary tracts), make up the secretory portions of glands and their ducts, …
Which are functions of epithelial tissue quizlet?
Functions as
protection, diffusion, filtration, absorption, secretion, and sensory reception
. The arrangement of layers within the epithelium; one is single, and the other is multiple layers.
What is not a function of epithelia?
(b)
often binds other tissues together
is not a function of epithelial tissue.
What is epithelial tissue made up of?
Epithelial tissue is composed of
cells laid out in sheets with strong cell-to-cell attachments
. These protein connections hold the cells together to form a tightly connected layer that is avascular but innervated in nature.
Is epithelial tissue vascular?
Whereas most tissues in the body are vascular (contain blood vessels),
epithelium is avascular
(a-vas′ku-lar), meaning it lacks blood vessels. Epithelial cells receive their nutrients from capillaries in the underlying connective tissue.
What is the nonliving material between cells?
A nonliving material, called
the intercellular matrix
, fills the spaces between the cells. This may be abundant in some tissues and minimal in others. The intercellular matrix may contain special substances such as salts and fibers that are unique to a specific tissue and gives that tissue distinctive characteristics.
What are three characteristics describe epithelial tissue?
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are
cellularity, polarity, attachment, vascularity, and regeneration
. Cellularity as the name suggests means that the epithelium is made up almost entirely of cells.
What is free surface of epithelial tissue?
The upper surface of epithelium
is free, or exposed to the outside of the body or to an internal body cavity. The basal surface rests on connective tissue. A thin, extracellular layer called the basement membrane forms between the epithelial and connective tissue.
How do we classify epithelial tissue?
Classification of Epithelial Tissues. Epithelial tissues are classified according to
the shape of the cells and number of the cell layers formed
((Figure)). Cell shapes can be squamous (flattened and thin), cuboidal (boxy, as wide as it is tall), or columnar (rectangular, taller than it is wide).
What is a epithelial cell in medical terms?
The term “epithelium” refers to
layers of cells that line hollow organs and glands
. It is also those cells that make up the outer surface of the body.
What is epithelial cells abnormality?
It means it
looks like your cells could be abnormal
. This could be because of an infection, such as a yeast infection or the herpes virus. Hormone changes from pregnancy or menopause can also affect test results.
What properties are shared by all types of epithelia? Epithelial cells
line a surface, are tightly packed, are situated on top of a basal lamina, and form an active and protective interface with the external environment
.
