B IO 202: Anatom y an d Physiology
Qu estions and an sw er s w ith
accu r ate r ationales(PASSED)
What is a tissue? - answer a group of cells with a common origin in an
embryo that function together
What is histology? - answer the study of tissues
What is a pathologist? - answer a physician that examines cells and
tissues for changes that indicate disease
What are the main types of tissues? - answer Epithelial, connective,
muscular, and nervous
Where do epithelial tissues reside in the body? - answer covers body
surfaces, lines hollow organs, cavities, and ducts, forms glands
What does epithelial tissue allow the body to do? - answer interact with
internal and external environments
Which type of tissue has the most variety of shapes? - answer Epithelial
tissues
,What is the function of connective tissue? - answer protects and
supports the body and organs, binds organs together, and stores energy
as fat
Which types of tissue has the most diversity? - answer Connective
tissue
What type of tissue provides immunity? - answer Connective tissue
What is the function of muscular tissue? - answer cells are specialized
for contraction and generation of force as well as generating heat for
body warmth
What is the function of nervous tissue? - answer detects changes in
condition inside and outside the body, it generates action potentials
that activate muscular contractions and glandular secretions
What is a biopsy? - answer removal of living tissue for examination,
helps diagnose cancer, infections, and inflammation
What are cell junctions? - answer contact points between plasma
membranes of tissues
, What are the types of cell junctions? - answer tight junctions, adherens
junctions, desmosomes, hemidesmosomes, and gap junctions
What are tight junctions? - answer weblike transmembrane proteins
that fuse outer surfaces of plasma membranes to seal off passageways
What do tight junctions do? - answer form a water tight seal between
cells that can block water, ions, and other molecules from moving past
the cells, prevents leakage into blood and tissues
What are adherens junctions? - answer they contain plaque that attach
to both membrane proteins and microfilaments
How do adherens junctions work? - answer Cadherins insert themselves
into the plaque, they cross the intracellular space and connect to the
cadherins of another cell
What do adherens junctions help with? - answer They help epithelium
resist tearing during contractile activities like digestion
What are desmosomes? - answer contain plaque and cadherins that
attach to other cells, but the plaque attaches to intermediate filaments
instead of microfilaments
