2. Simple (= single layer)
Cuboidal
• Description: Single
layer of cube-
shaped cells.
• Location: small
ducts of
glands, kidney Cell is as wide as it is high. One
central nucleus
tubules, surface of
ovary.
• Function: secretion
& absorption
3. Simple
Cuboidal Lumen:
Inside space of
• Cells closely packed Tubular structure
together and touching
one another
• Has a basal surface Nucleus
Apical
Surface
and apical surface Basal
Surface
• Avascular
• Sits on a basement
membrane (difficult to
see on slide)
4. Non- Ciliated Simple Columnar
• Description: Single
layer of non-ciliated
rectangular cells;
contain goblet cells
and sometimes
microvilli.
• Location: GI
tract, ducts, gallbladd
er
• Function: secretion
and absorption
5. • Nuclei lie near base of cell
Simple Columnar Cells
• Goblets secrete mucous at
apical surface to lubricate Goblet Cell
lining of Nucleus
GI, respiratory, reproductiv
e and urinary systems.
• Microvilli increase surface
area for absorption.
Goblet Cell
6. Pseudostratified Ciliated Columnar
Epithelium
• Appears stratified
because nuclei are at
varying levels.
• Ciliated lines airways
of upper respiratory
tract.
• Mucus from Goblets Goblet Cells
traps foreign
particles and are
swept away by cilia.
10. Teased Dense Regular Connective Tissue
• Forms tendons and
ligaments and
aponeuroses.
• Matrix looks white
and shiny.
• Mostly collagen
fibers with
fibroblasts between
rows.
• Strong attachment!
12. Reticular
Connective Tissue Reticular Cells
• Network of interlacing
reticular fibers & Blue staining
reticular cells Reticular fibers
• Found in stroma
(framework) of
liver, spleen, lymph
nodes, red bone
marrow
• Acts as a filter in spleen
and lymph nodes.
13. Reticular Connective Tissue
• Remember that
connective tissue is
vascular. (Avascular
epithelial tissue
depends on diffusion
of nutrients and
waste through blood Blood vessel:
Single layer of
vessels in CT. Epithelial cells
forms vessel tube.
15. Hyaline
Cartilage
• Often called gristle
• Bluish white smokey chondrocytes
looking ground
substance
• Numerous chondrocytes
• Location: ends of long Ground S
bones, ribs, nose, trache
a, larynx, bronchi
• For flexibility and
support
• Most abundant type of
cartilage in body
16. Elastic Cartilage
• Chondrocytes are
located within
threadlike network
of elastic fibers
• Location: Epiglottis
of larynx, external
ear, Eustachian
tubes
• For support and
shape

18. Adipose
Tissue
• Adipocytes, “signet
ring” cells with
peripheral nuclei.
• For storage of
triglycerides, to
reduce heat loss, and
serve as an energy nucleus
reserve.
• Location: under
skin, around heart &
kidneys, yellow “signet ring”
marrow, behind adipocyte
eyeball
19. Osseous Tissue (Bone)
• Compact bone consists of
osteons (haversion
systems) that contain:
– Lamellae
– Lacuna
– Osteocytes
– Canaliculi
– Central (haversion)canals
• Spongy bone consists of
thin plates called
trabeculae filled with red
marrow
