Four major tissue types
Epithelial, connective, muscle and nervous
Tissue
Cells are arranged in groups and layers that provide specific functions for the body.
How are epithelial tissues categorized?
By Shape and Layer
General Characteristics of Epithelial Tissue
-anchored to a basement membrane
- made up of tightly packed cells containing little intercellular material
-lack blood vessels
-replaced frequently.
Where is Epithelial tissue found?
Covers body surface
Lines internal organs
Composes glands
Simple Squamous Epithelium is made up of?
Simple squamous epithelium is made up of a single layer of thin, flattened cells.
The Job: Simple Squamous Epithelium
DIFFUSION, Exchange of Gases
Location: Simple Squamous Epithelium
Lungs, lines blood, lymph vessels, and body cavities.
The Job: Simple Cuboidal Epithelium
functions in secretion and absorption
Nuclei of Simple Squamous Epi?
Broad and Thin
Nuclei of Simple cuboidal epi.?
Centrally Located Spherical Nuclei
The Location: Simple Cuboidal Epithelium
Kidneys, secretion in the glands, covers the ovaries
Which type of epi has cilia
Simple Columnar
The Location: Simple Columnar Epithelium
uterus, stomach, and intestines
The Job:Simple Columnar Epithelium
Secretion and Absorption; protects underlying tissues
Simple Columnar Epithelium in the intestine
cells possess microvilli that increase the surface area available for absorption
Microvilli
tiny cylindrical processes extending from the simple columnar cell
Goblet Cells
Found among columnar epithelium. Secrete a protective fluid=mucus onto the tissue
The Location: Pseudostratified Columnar Epithelium
trachea, respiratory system
Pseudostratified Columnar Epithelium Nuclei?
appear layered due to the varying positions of their nuclei within the row of cells
The Location: Stratified Squamous Epithelium
outer layer of skin, and lines the mouth, throat, vagina, and anal canal.
Cilia may be present, along with mucus-secreting globlet cells, that line and sweep debris from respiratory tubes?
Pseudostratified Columnar Epithelium
The Job: Stratified Squamous Epithelium
Protection.
The Location: Stratified Cuboidal Epithelium
mammary glands, sweat glands, salivary glands, and pancreas
How many layers of Stratified Cuboidal Epithelium are there?
2-3 layers
Stratified Columnar Epithelium: Location
ductus deferens, part of the male urethra, and parts of the pharynx.
Transitional Epithelium:JOB
designed to distend and return to its normal size
Transitional Epithelium:Location
Lining of the bladder
distensibility
Function that Transitional Epithelium has to prevent urine from coming back into the body.
Glandular Epithelium:JOB
produce and secrete substances into ducts or into body fluids.
Glands that secrete products into ducts are?
exocrine
Glands that secrete into body fluids and blood are called?
endocrine.
Glands that release fluid products by exocytosis (pancreas) and are grouped as serous which produce a watery fluid or mucus which produce a thicker, protective substance?
Merocrine.
glands lose portions of their cell bodies during secretion (mammary glands).
Apocrine.
glands release entire cells (sebaceous glands).
Holocrine
bind, support, protect, serve as frameworks, fill spaces, store fat, produce blood cells, protect against infection, and repair tissue damage.
Connective Tissue
Which tissue has an abundance of extra cellular matrix, and good blood supply?
Connective Tissue
the most common cell type, and is a fixed, star-shaped cell that secretes fibers and is large in size.
Fibroblast
function as scavenger cells and defend against infection.
Macrophages
large and are located near blood vessels where they release heparin (anticoagulant) and histamine (promotes inflammation)
Mast Cells
Three types of Connective Tissue Fibers
collagenous, Elastic, Reticular
Collagenous Fibers
made of collagen, holds body together
Elastic Fibers
Made of elastin, easily stretched....vocal cords
Reticular Fibers
thin collagenous fibers that form supportive networks
Type of connective tissue that forms delicate, thin membranes throughout the body that bind body parts together such as skin and underlying organs.
Areolar Tissue
Adipose Tissue
loose connective tissue designed to store fat
composed of thin, collagenous fibers in a 3-D network.
Reticular connective tissue
This tissue consists of densely packed collagenous fibers and is very strong but lacks a good blood supply.
Dense Connective Tissue
Connective Tissue found as part of tendons and ligaments?
Dense Connective Tissue
Rigid connective tissue that provides a supportive framework for various structures...?
Cartilage
Cartilage cells
(chondrocytes)
The common type of cartilage found at the ends of bones, and supports respiratory passages?
Hyaline Cartilage
provides a framework for the external ears and parts of the larynx
Elastic Cartilage
tough tissue that provides a shock- absorbing function in intervertebral discs and in the knees and pelvic girdle.
Fibrocartilage
Composed of cells (red and white) suspended in a liquid matrix called plasma?
Blood
good blood supply, enabling rapid recovery after an injury.
BONE
thin, sheetlike structures composed of epithelium and connective tissues, covering body surfaces and lining body cavities.
Epithelial membranes
four main types of membranes:
serous, mucous, cutaneous, and synovial.
voluntary movements of skeletal parts, striated
Skeletal Muscle tissue
Involuntary, walls of hollow internal organs, no striations
Smooth Muscle tissue
Heart Movements, heart muscles, striated
Cardiac Muscle
Sensory reception and conduction of electrical impulses
Nervous tissue
