Chapter 4: Tissues:The Fabric of Life Flashcards
Epithelial Tissue: flattened scale like
squamous
Epithelial Tissue: cube like
cuboidal
Epithelial Tissue: tall and column shaped
columnar
Simple epithelial is composed of a___ cell layer
single
Stratified epithelial is composed of ___ or more cell layers
2
Define: histology
study of tissues
Define: tissue
collections of cells that have a similar or common function
Stratified epithelial is usually found in
High abrasion areas such as skin and lining of the mouth
Simple epithelial is usually found
Passage or filtration occurs and little protection is needed
4 main types of tissues
connective, epithelium, muscle, nervous
Tissues come together collectively to form___
organs
This tissue forms boundaries between different environments; protects, secrets, absorbs, filters
epithelial tissue
This tissue contracts to cause movement
muscle tissue
This tissue is responsible for internal communication and is located in the brain, spinal cord, and nerves
nervous tissue
This tissue supports, protects, binds other tissues together
connective tissue
This is the most abundant tissue in the body
Connective
Characteristics of epithelial tissue
Polarity, cells are closely packed, avascular but innervated, regenerative, supported by connective tissue
Define: Polarity
always can tell what the superficial and basal surface is
Apical surface is always ___ and not connected to any other____
free; tissues
Basal surface is the _____ membrane and is attached to other ___
basement; tissue
Epithelial Tissue: 1 layer; flat cells; this tissue(not used for protection)
simple squamous
Epithelial Tissue: allows the passage of materials by diffusion and filtration; secrets lubricating substances in serosae
Simple squamous
Epithelial Tissue: located in kidney glomeruli and air sacs of lungs; lining of heart, blood vessels, and lymphatic vessels, and ventral body cavity
simple squamous
Epithelial Tissue 1 later; cube like cells; thicker than simple squamous
simple cuboidal
Epithelial Tissue: absorption and secretion
simple cuboidal
Muscle Tissue: contracts, propels blood into circulation; involuntary control
cardiac
Muscle Tissue: located of heart walls
cardiac
Muscle Tissue: branching striated; uninucleated cells; intercalated discs
cardiac
3 types of muscle tissues
skeletal, cardiac, smooth
Muscle Tissue: striated; multinucleated; cells perfectly parallel
skeletal
Muscle Tissue: located- muscles attached to bones and skin
skeletal
Muscle Tissue: function- voluntary movement; locomotion
skeletal
Muscle Tissue: NOT striated
smooth
4 types of connective tissue
connective tissue proper, blood, bone, cartilage
Structural Elements of Connective tissue
Ground substance, fibers, cell type
Connective tissue cell type: fibroblast
connective tissue proper
Connective tissue cell type: chondroblast or chondrocyte
cartilage
Connective tissue cell type: osteoblast or osteocytes
bone
Connective tissue fibers: 3 types
collagen, elastin, reticular
Characteristics of Collagen Fibers
think, pink, straight
Characteristics of elastic fibers
thin, darker in color, squiggly
Characteristics of reticular fibers
tree branches
Subcategories of connective tissue proper
loose connective tissue and dense connective tissue
Types of Loose Connective tissue
areolar, adipose, reitcular
Types of dense connective tissue
dense irregular, dense regular, elastic
Difference between loose and dense connective tissue
fibers that bind cells are not packed together and there is more ground substance in loose
