Connective Tissue

What type of tissue:

Fills internal spaces

Supports other tissues

Transports material

Stores energe

Muscle Tissue

What type of tissue:

Specialized for contraction

Skeletal muscle, heart muscle, and walls of hollow organs

What type of Tissue

Carries electrical signals from one body part to another.

What type of Tissue:

Layers of cells covering internal or external surfaces.

Move Fluids over the epithelium (protection)

Move fluids through the epithelium (pereability)

Produce secreation (protection and messengers)

Intercelluar connextion

Attachment to the basil lamina

Epithelial Maintenance and repair

Cell Junctions

Form bonds with other cells or extracellular material

-occluding (tight)junctions

-gap junctions

-macula adherens (desmosomes)

Between two plasma membranes

Adhesion belt attaches to the terminal web

prevents passage of water and solutes

isolates wastes in the lumen

Gap Junctions

-allow rapid communication

-held together by channel proteins(junctional proteins, connexons)

-allow ions to pass

-Coordinate contractions in the heart muscle

-CAMs, dense areas, and intercellular cement

-tie cells together

-allow bending and twisting

Clear Layer (lamina lucida)

- Thin Layer

-Secreted by epithelia

-Barrier to proteins

-Thick Fibers

-Produced by connextive tissue

-Strength and filitration

Location:Mesothelia lining ventral body cavities, endothelia lining heart and bloodvessels; portions of kidney tublues( thin sections of nephron loops) inner lining of cornea; alveoli of lungs

Functions: Reduces friction; controls vessel permeability; performs absorption and secreation

Protects against attacks

Keratin protein adds strength and water resistance

Locations: Surface of skin, lining of mouth throat, esophagus, rectum, anus, and vagina

Functions: Provides physical protection against abrasion, pathogens, and chemical attack

Locations: Glands; ducts; portions of kidney tubules, thyroid gland

Functions: Limited protection, secreation, absorption

Location: Lining of some ducts(rare)

Functions: Protection, secreation, absorption

-Tolerates repeated cycles of stretching and recoiling and returns top its previous shape without damage

-Appreance changes as stretching occurs

-Situated in regions of the urninary system (e.g. urinary bladder)

Locations: Urinary bladder; renal pelvis, ureters.

Functions: Permits expansionand recoil after stretching

Release Horomones

-into interstitial fluid

-no ducts

Produce Secreations

-onto epithelial surfaces

-through ducts

Merocrine Secreation

Apocrine Secreation

Holocrine Secreation

-is produced in the golgi apparatus

-is released by vesicles ( exocytosis)

- For example, sweat glands

Is produced int he golgi apparatus

is released by shedding cytoplasm

for example, mammory gland

Is released by cells bursting, killing gland cells

gland cells replaved by stem cells

for example, sebaceous gland

Serous gland

mucous glands

mixed exocrine glands

connect epithelium to the rest of the body(basil lamina)

Provide structure (bone)

Store energy (Fat)

Transport material (blood)

Have no contact witht he outside enviroment.
