____ is the name given to the single layer of squamous or cuboidal cells that line mesentery (____ is the name given to the single layer of squamous cells that lines vessels).
Mesothelium
endothelium
Loose( areolar) connective tissue has loose arrangement of the ____(thicker, pink) and ____(thinner) fibers.
collagenous
elastic fibers
toluidine blue which colors mast cell granules ___
purple
superficial layer of the dermis, known as the ____, is made up of ____ CT.
papillary layer
areolar
Areolar CT has an abundance of ___ throughout the connective tissue.
mast cells
A good example of areolar connective tissue (CT) can be found in the mucosal (luminal) lining of the ____
digestive tract
The mucosa consists of three tissue layers:
epithelium
lamina propria
muscularis mucosae.
The lamina propria is composed of ____
areolar connective tissue.
areolar connective tissue is made of mostly ___
scattered cells and extracellular matrix or ECM.
ECM is a loose network of fine fibers and ground substance (composed mainly of glycoproteins and glycosaminoglycans) located between the scattered cells and the fibers
between the mucosa layer and the thick outer layer of smooth muscle, is a layer called the ___
submucosa
the layer of thick smooth muscle outside the DICT of the submucosa is the ___
muscularis externa
The submucosa consists of ____
dense irregular connective tissue
in dense irregular connective tissue:
there is ___ thick collagen fibers than cells.
Collagen fibers are arranged in seemingly ____ (hence the name “irregular”).
more
random orientations
The submucosa is surrounded on both sides by ____
smooth muscle
closer to the epithelium, the submucosa is bounded by a thin layer of smooth muscle called the ____
On the opposite side, the submucosa is bounded by a thick layer of smooth muscle known as the ____
muscularis mucosae
muscularis externa
Reticular layer of the dermis, is an excellent example of ____
dense irregular CT
deeper layer of dermis
reticular layer
layers of dermis
reticular layer -dense irregular CT
papillary layer - areolar CT
the papillary layer of the dermis is formed from ___
areolar CT
It has finer fibers, a looser texture and generally more scattered cells than the reticular layer
the areolar CT has ___ fibers, a looser texture and generally___scattered cells than the reticular layer
finer

the capsule of boar epididymis is an example of what type of connective tissue
particularly compact dense irregular connective tissue
The fibers are woven together to form a tightly knit outer covering.
in dense regular connective tissue like ___, the fibers form in ____
tendons
preferred orientation (hence the name “regular”).
The parallel arrays of collagenous fibers are so dense that only the very flat nuclei of the fibroblasts can be seen in between.
In dense regular connective tissue, The ____ arrays of collagenous fibers are so dense that only the very flat nuclei of the ____ can be seen in between.
parallel
fibroblast
