Histology & Integument

passage of nerves

Function: binds epithelia ilia to deeper tissues, allows ________ and vessels through tissues.

Pseudo

________ stratified Columnar Epithelium: single layer of tall and short cells.

Simple Columnar Epithelium

________: Single layer of tall /narrow cells (may make goblet cells)

Cuboidal Epithelium

Simple ________: single layer of round cells.

collagen fibers

Dense: densely packed ________, wavy /shiny appearance, very little ground substance (not much open space)

Squamous Epithelium

Simple ________: single layer of flat cells.

Fibro cartilage

________: Lacunae often in rows; collagen fibers give shiny appearance.

Elastic cartilage

________: lacunae randomly arranged, stringy elastic fibers present.

Basement membrane

________: anchors epithelium to connective tissue and allows for exchange of nutrients and waste.

Pseudo

________ stratified: all cells touch basement membrane.

-pseudo stratified

all cells touch basement membrane

-basement membrane

anchors epithelium to connective tissue and allows for exchange of nutrients and waste

Squamous

flat

Cuboidal

cube shaped

Columnar

column or rectangle shape

Simple Squamous Epithelium

single layer of flat cells

Location

Alveoli and capillaries

Function

Allows for rapid diffusion

Simple Cuboidal Epithelium

single layer of round cells

Location

Kidneys and glands

Function

Absorption and secretion

Simple Columnar Epithelium

Single layer of tall/narrow cells (may make goblet cells)

Location

Gi tract and uterus

Function

Absorption and secretion

Pseudo stratified Columnar Epithelium

single layer of tall and short cells

Location

Respiratory tract

Function

Secrete and propel mucus

Stratified Squamous

many cell layers, basal cells appear round become increasingly flattened as they near apical surface, may be keritanized

Location

epidermis, mouth, anus, vagina

Function

resist abrasion, protection

Diverse set of tissues includes

fibrous, adipose, cartilage, bone, and blood

2 main functions

bind other tissues together and protect organs

Dense

densely packed collagen fibers, wavy/shiny appearance, very little ground substance (not much open space)

Location

tendons, ligaments, dermis

Function

resist stress

Loose

all 3 fiber types randomly arranges, lots of ground substance

Location

dermis, underlying all epithelia

Function

binds epithelia ilia to deeper tissues, allows passage of nerves and vessels through tissues

Adipose

lots of adipocytes (large, empty-looking cells)

Location

hypo-dermis, breast, surrounding organs

Function

energy storage, insulation, cushion

Hyaline cartilage

lacunae often appear in pairs; collagen fibers give shiny appearance

Location

nose, repiratory tract, articular cartilage (at sonovial joints), costal cartilage

Function

Structural support

Elastic cartilage

lacunae randomly arranged, stringy elastic fibers present

Location

ear, epiglotis

Function

Flexible elastic support

Fibro cartilage

Lacunae often in rows; collagen fibers give shiny appearance

Location

pubic symphysis; invertebrate discs; knee

Function

Shock absorption

Location

Skeleton

Function

Structural support, protection, calcium storage

Location

heart, blood vessels

**Function

**transport; immune defense
