Classification of Tissues
Smooth muscle
Active during birth In wall of bladder & stomach One nucleus Spindle-shaped cells Involuntary Arranged in sheets
Insulates against heat loss; provides reserve fuel
Adipose connective
How does the special structure of a neuron relate to its function?
Allows a single neuron to conduct an impulse over relatively long distances
Composes basement membranes; a soft packaging tissue with a jellylike matrix
Areolar connective tissue
On what bases are epithelial tissues classified?
Arrangement ( relative number of layers); cell shape (squamous, cuboidal, columnar)
Abundant nonliving extracellular matrix
Connective Type
Anchors and packages body organs
Connective Type
The most durable tissue type
Connective Type
Attaches bone to bones & muscles to bones
Dense fibrous connective
Where is ciliated epithelium found?
Lines trachea, most of the upper respiratory tract
Lines much of the respiratory tract
Pseudostratified ciliated columnar
Propels substances across its surface
Pseudostratified ciliated columnar
Lines the small and large intestines
Simple columnar epithelium
Tubules of the kidney
Simple cuboidal
Most suited for rapid diffusion
Simple squamous
How are they different?
Their cytoplasm is drawn out into long extensions (cell processes)
Best suited for areas subject to friction
Stratified squamous epithelium
Stretches
Transitional
How are the functions of connective tissue reflected in its structure?
The functions of connective tissue are protection, support, & binding other tissues together - reflected in matrix for strength & fibers for support.
Cells may absorb, protect, or form a filtering membrane
Epithelium Type
Lines body cavities & covers the body's external surface
Epithelium Type
Cardiac muscle
Forms heart walls Striated Branching cells One nucleus Intecalated discs Involuntary Active during birth Cylindrical cells
How is the function of an epithelium reflected in its arrangement?
Function of epithelial cells is to form linings or covering membranes - reflected in the arrangement of fitting closely together to form intact sheets of cells.
Tissue
Groups of cells that are similar in structure & function
How does this reflect is function in body?
Has the ability to slide over one another to allow the organ to be stretched
Firm matrix heavily invaded with fibers; appears glassy & smooth
Hyaline cartilage
Forms the larynx & the costal cartilages of the ribs
Hyaline cartilage
Transitional epithelium is actually stratified squamous epithelia?
It differs from other stratified squamous epi's by being rounded
What role does it play?
Motile cell projections that help to move substances along the cell surface
Major function is to contract
Muscular Type
Pumps blood, flushes urine out of the body, allows one to swing a bat
Muscular Type
Forms nerves
Nervous Type
Most involved in regulating body functions quickly
Nervous Type
Transmits waves of excitation
Nervous Type
What is the makeup of the matrix in connective tissues?
Nonliving material composed of ground substances- (glycoproteins & large polysaccharide molecules) & fibers
In what ways are nerve cells similar to others cells?
Nucleus-containing cell with cytoplasm
Forms your hip bone
Osseous tissue
Matrix hard; provides levers for muscles to act on
Osseous tissue
Skeletal muscle
Voluntary Cylindrical cells Many nuclei Striated Moves limbs, produces smiles Attached to bones
