with Answers Rated A
Simple Squamous - -structure - single layer of thin, cells are binucleated
flat cells resembling irregular floor tiles; the single nucleus function - distension (stretching) and relaxation to
of each cell bulges at its center accommodate urine volume changed in the urinary
function - rapid diffusion, filtration, and some secretion in bladder, ureters and part of the urethra
serous membranes location - lining of urianry bladder, ureters, and part of the
location - air sacs in lungs (aveoli); lining lumen of lymph urethra
vessels and blood vessels (endothelium); serous
membranes of body cavities (mesothelium)
areolar connective tissue - -structure - abundant,
viscous ground substance; scattered fibroblasts; many
simple cuboidal - -structure - single layer of cells blood vessels
about as tall as they are wide; spherical and centrally function - protects tissues and organs; binds skin and
located nucleus some epithelia to deeper tissue
function - absorption and secretion, forms glands and location - papillary layer of the dermis (skin);
small ducts subcutaneous layer (deep to skin); surrounds organs,
location - thyroid gland follicles; surface of ovary; kidney nerve cells, some muscle cells, and blood vessels
tubules; secretory regions and ducts of most glands
reticular connective tissue - -structure - viscous
simple columnar - -- contains one layer of uniformly ground substance; scattered arrangement of fibers,
shaped cells that are about as tall as they are wide with a leukocytes, and some fibroblasts
centrally located spherical nucleus function - provides stroma (supportive framework) to
- absorption and secretion lymphatic organs
- forms the follicles (spherical structures) of the thyroid location - spleen, lymph nodes, and red bone marrow
gland and covers each ovary; composes the walls of small
ducts (or tubules) including those of kidney tubules
epithelial tissue - -
stratified squamous - -- has multiple cell layers and
only the deepest layer of cells is in direct contact with the connective tissue - -they all originated from an
basement membrane embryonic _____ called mesenchyme (discussed in
- the cells in the basal layers have cuboidal or polyhedral section 5.2c). In addition, while almost all connective
shape, whereas the apical cells display a flattened, tissue is vascular, the different types of ... exhibit a range
squamous shape of vascularity, from very vascular to poorly vascular to
- protects the underlying tissues from damage caused by avascular.
abrasion and friction
- epidermis of the skin, oral cavity
muscle tissue - -
pseudostratified columnar - -- one layer of tall cells
that appear stratified nervous tissue - -
- appears to consist of multiple layers of cells
- epithelium is not really stratified because all of its cells
are in direct contact with the basement membrane adipose connective tissue - -structure - closely
- its cells always reach the apical surface and the shorter packed adipocytes; nucleus pushed to edge of cell by
cells are stem cells that give rise to the columnar cells large fat droplet; contains many blood vessels
function - stores energy; insulates, cushions and protects
