ANIMALS QUESTIONS WITH CORRECT ANSWERS
Tissue - CORRECT ANSWER -A group of cells with a common origin, structure, and function
Who coined the term tissue? - CORRECT ANSWER -Francois Xavier Bichat, father of modern
histonology
Histology - CORRECT ANSWER -study of tissues
How many types of animal tissues are there? - CORRECT ANSWER -Four
What are the four types of tissues? - CORRECT ANSWER -epithelial, connective, muscle, nervous
epithelial tissue functions - CORRECT ANSWER -covering tissue, protects underlying tissues,
storage of materials, diffusion, absorption, secretion, etc.
Connective tissue - CORRECT ANSWER -connects, supports, penetrates, and encases various
body structures
Muscular tissue - CORRECT ANSWER -locomotion and movement
Nervous tissue - CORRECT ANSWER -Coordinates, regulates, and integrates body functions
Origin of epithelial tissue - CORRECT ANSWER -ectoderm, mesoderm, endoderm
How much intercellular space is in epithelial tissue? - CORRECT ANSWER -little to none
,How do cells in epithelial tissues communicate? - CORRECT ANSWER -cell junctions
Basement membrane - CORRECT ANSWER -Cells at the base of an epithelial layer are attached
to this noncellular
non-vascular/avascular tissue - CORRECT ANSWER -Tissue that does not receive direct blood
supply
Is epithelial tissue vascular or avascular? - CORRECT ANSWER -avascular
How does epithelial tissue get nutrients? - CORRECT ANSWER -Diffusion from underlying
connective tissue
Location of epithelial tissue - CORRECT ANSWER -body coverings, body linings, glandular tissue
How is epithelial tissue classified? - CORRECT ANSWER -number of layers and shape
simple epithelium - CORRECT ANSWER -single layer of cells
compound epithelium - CORRECT ANSWER -different layers of cells
squamous epithelium - CORRECT ANSWER -flat, scale-like cells
Where is squamous epithelium found? - CORRECT ANSWER -areas specialized for diffusion such
as alveoli, air sacs, blood capillaries, etc., also epidermis
function of squamous epithelium - CORRECT ANSWER -diffusion and filtration
, cuboidal epithelium - CORRECT ANSWER -cube shaped cells with prominent nuclei
endothelium - CORRECT ANSWER -the specialized squamous epithelial tissue that lines the
blood and lymph vessels and heart
Pavement epithelium - CORRECT ANSWER -squamous epithelium
Location of cuboidal epithelium - CORRECT ANSWER -Kidney tubules; ducts and secretory
portions of small glands; ovary surface
Function of cuboidal epithelium - CORRECT ANSWER -secretion and absorption
Brush bordered cuboidal epithelium - CORRECT ANSWER -specialized cuboidal cells lining
proximal convoluted tubule, have microvilli
Microvilli - CORRECT ANSWER -Fingerlike extensions of plasma membrane of apical epithelial
cells, increase surface area, aid in absorbtion, exist on every moist epithelia, but most dense in
small intestine and kidney
germinal cuboidal epithelium - CORRECT ANSWER -thick layer of cells that covers the sex organs
during the early developmental stage of the embryo
Pigmented cuboidal epithelium` - CORRECT ANSWER -epithelial cells that are highly pigmented
due to the numerous large melanosomes which pack the cytoplasm of each cell, found in layer
just behind iris
columnar epithelium - CORRECT ANSWER -Single layer column shaped cells
