Studied by 8 peoplewhat is the most abundant and widely distributed tissue in the body
connective tissue
what tissue’s main goal is support
connective tissue
what are the three type of connective tissue
connective tissue proper, cartilage, bone, blood
List the jobs of connective tissue
binding and support, protection, insulation, transport
connection tissue consists primarily of
extracellular matrix
what are the 3 types of fibers
collagen, elastic, reticular collagen
what protein is the most common and tough
collagen
what fibers are stretchy
elastic
what fibers are thinner and form a “net” for strength
reticular
what are embryonic stem cells that CT cells are comprised of
mesenchyme
what is comprised of extracellular fibers and ground substance for most CT
extracellular matrix
what cells release histamine and heparine after injury/infection
mast cells
what consumes damages cells/invaders
macrophages
example of macrophage
white blood cell
what are always present in CT to secrete fibers/ground substances and makes the extracellular matrix?
fibroblasts
what cells make 3 types of cartilage
chondrocytes
what is the space that remains after the chondrocyte dies
lacunae
what are bone-forming cells
osteoblasts
which tissue can carry electrical impulse across long or short distances
nervous tissue
how does nervous tissue carry electrical impulses
through neurons
are neurons short or long living
long living
nervous tissue cells have both
conductivity and irritability
which tissue forms boundaries between environments
epithelial tissue
what are the jobs performed by the epithelium
protection, absorption, filtration, excretion, secretion, sensory perception
outside surface of epithelial tissue is called
apical
inside surface of epithelial tissue is called
basal
simple means
single layer
stratified means
many layers
squamous cells are shaped like
fried eggs
cuboidal cells distinguishable quality is
length, width, height are similar
columnar cells distinguishable quality is
length and width is similar, height is many times more
groups of cells that are similar in structure and perform a common function are called
tissues
what type of cellular joining is described:
cells held so close to each other even water can’t get through. they line waterproof passages
tight junctions
example of a tight junction
intestines
what type of cellular joining is described:
heavily anchored protein plates attached to each other like velcro. made for tissues to withstand shearing forces (lateral force)
desmosomes
example of desmosomes
skin
what type of cellular joining is described:
have holes through proteins that allow ions to move cell to cell but still being held close together so that water can’t get through.
gap junctions
example of a gap junction
cardiac muscles
basic groups of tissues
epithelial, connective, muscle, nervous
