Term
Connective Tissue(Found+Functions 5)
Definition
 .Found everywhere in the body
 .Includes the most abundant and widely
distributed tissues
 Functions
 .Binds body tissues together
 .Supports the body
 .Provides protection
Term
Connective Tissue Charateristics(4)
Definition
 .Variations in blood supply
. Some tissue types are well vascularized
. Some have a poor blood supply or are
avascular
 .Extracellular matrix
 Non-living material that surrounds living cells
Term
Extracellular Matrix(main elements and types of fibers(3))
Definition
 Two main elements
 .Ground substance—mostly water along with
adhesion proteins and polysaccharide
molecules
 .Fibers
 Produced by the cells
 Three types
 Collagen (white) fibers
 Elastic (yellow) fibers
 Reticular fibers
Term
Bone(type,composed of, function)(5)
Definition
.a connective tissue
 Composed of
 .Bone cells in lacunae (cavities)
 .Hard matrix of calcium salts
 .Large numbers of collagen fibers
 Used to protect and support the body
Term
Hyaline cartilage (type, composed(2), locations(2))
Definition
.type of connective tissue
.Most common type of cartilage
 Composed of
 .Abundant collagen fibers
 .Rubbery matrix
 Locations
. Larynx
. Entire fetal skeleton prior to birth
Term
Elastic cartilage(3)
Definition
.type of connective tissue
.provides elasticity
.supports the external ear
Term
Fibrocartilage(2)
Definition
.type of connective tissue
.forms cushion like discs between vertebrae
Term
Dense connective tissue (dense fibrous tissue)(3)
Definition
.Main matrix element is collagen fiber
.Fibroblasts are cells that make fibers
.found in tendons, ligaments and dermis
Term
Tendons
Definition
attach skeletal muscle to bone
Term
Ligaments
Definition
attach bone to bone at joints
Term
Dermis
Definition
lower layers of the skin
Term
Areolar tissue(6)
Definition
.Loose connective tissue types
.Most widely distributed connective tissue
.Soft, pliable tissue like “cobwebs”
.Functions as a packing tissue
.Contains all fiber types
.Can soak up excess fluid (causes edema)
Term
Adipose tissue(6)
Definition
.Loose connective tissue types
.Matrix is an areolar tissue in which fat globules predominate
.Many cells contain large lipid deposits
.Insulates the body
.Protects some organs
.Serves as a site of fuel storage
Term
Reticular connective tissue (7)
Definition
.loose connective tissue
.Delicate network of interwoven fibers
.Forms stroma (internal supporting
network) of lymphoid organs
.Lymph nodes
.Spleen
.Bone marrow
Term
Blood (vascular tissue)(3)
Definition
.connective tissue
.Blood cells surrounded by fluid matrix called blood plasma
.Fibers are visible during clotting
.Functions as the transport vehicle for
materials
Term
Muscle tissue (function + types)
Definition
 Function is to produce movement
 Three types
 Skeletal muscle
 Cardiac muscle
 Smooth muscle
Term
Skeletal muscle(6)
Definition
.Under voluntary control
.Contracts to pull on bones or skin
.Produces gross body movements or facial
expressions
.Striated
.Multinucleate (more than one nucleus)
.Long, cylindrical
Term
Cardiac muscle(6)
Definition
.Under involuntary control
.Found only in the heart
.Function is to pump blood
.Cells are attached to other cardiac muscle cells at intercalated disks
.Striated
.One nucleus per cell
Term
Smooth Muscle(5)
Definition
.Under involuntary muscle
.Found in walls of hollow organs such as
stomach, uterus, and blood vessels
.No visible striations
.One nucleus per cell
.Spindle-shaped cells
Term
Nervous Tissue(4)
Definition
.Composed of neurons and nerve support cells
.Function is to send impulses to other areas of the
body
 Irritability
 Conductivity
Term
tissue regeneration
Definition
Replacement of destroyed tissue by the same kind of cells
Term
Fibrosis
Definition
Repair by dense (fibrous) connective tissue(scar tissue)
Term
Determination of method
Definition
Type of tissue damaged
 Severity of the injury
Term
Events in Tissue Repair
Definition
 Capillaries become very permeable
 Introduce clotting proteins
 A clot walls off the injured area
 Formation of granulation tissue
 Growth of new capillaries
 Rebuild collagen fibers
 Regeneration of surface epithelium
 Scab detaches
Term
Regeneration of Tissues
Definition
 Tissues that regenerate easily
 Epithelial tissue (skin and mucous
membranes)
 Fibrous connective tissues and bone
 Tissues that regenerate poorly
 Skeletal muscle
 Tissues that are replaced largely with scar tissue
 Cardiac muscle
 Nervous tissue within the brain and spinalcord
Term
Developmental Aspects of Tissue(4)
Definition
Epithelial tissue arises from all three primary germ layers
 Muscle and connective tissue arise from the mesoderm
 Nervous tissue arises from the ectoderm
 With old age, there is a decrease in mass and viability in most tissues
Term
Epithelial Tissues(locations (3), Functions (4))
Definition
Locations
 Body coverings
 Body linings
 Glandular tissue
Functions
 Protection
Absorption
Filtration
Secretion
Term
Epithelium Characteristics(4)
Definition
.Cells fit closely together and often form sheets
.One side is a free surface and the other rest on a basement membrane.
.Avascular (no blood supply)
.Regenerate easily if well nourished
Term
Simple
Definition
one layer
Term
Stratified
Definition
more
than one layer
Term
Simple squamous(4)
Definition
.Single layer of flat cells
.Usually forms membranes
.Lines body cavities
.Lines lungs and capillaries
Term
Simple cuboidal(4)
Definition
.Single layer of cube-like cells
.Common in glands and their ducts
.Forms walls of kidney tubules
.Covers the ovaries
Term
Simple columnar(3)
Definition
.Single layer of tall cells
.Often includes mucus-producing goblet cells
.Lines digestive tract
Term
Pseudostratified columnar(4)
Definition
.Single layer, but some cells are shorter than others
.Often looks like a double layer of cells
.Sometimes ciliated, such as in the respiratory tract
.May function in absorption or secretion
Term
