Simple Squamous Epithelium Major Functions: Diffusion and filtration Locations: Kidneys - filtration membrane lungs - alveolar (air sac) walls Capillary walls Endothelium - slick, friction reducing layer of simple squamous epithelium that lines the lymphatic vessels, blood vessels, and the heart. Mesothelium - the epithelium of serous membranes in the ventral body cavity |

Simple Squamous Epithelium |
|
|
Simple Cuboidal Epithelium Major Functions: secretion and absorption Location: Smallest ducts of glands and many kidney tubules |
|
|
Simple Cuboidal Epithelium |
|
|
Cancellous (Spongy) Bone Tissue - Bony plates called trabeculae. Lighter than compact bone, but still strong - Locations - in ends of long bones and inside all other bones |
|
|
Cancellous (Spongy) Bone Tissue |
|
|
Reticular Connective Tissue |
|
|
Reticular Connective Tissue - Loose connective tissue - Resembles areolar but fibers are reticular fibers - Provides a framework for organs - Found in lymph nodes, the spleen, the liver, and bone marrow |
|
|
Adipose Tissue - Lose connective tissue Functions: insulation, energy storage, and shock absorber - Similar to areolar in structure but greater nutrient storage - Adipocytes are filled with triglycerides (lipids) |
|
|
Adipose Tissue |
|
|
Nervous Tissue |
|
|
Nervous Tissue - Main component of nervous system Location: Brain, spinal cord, nerves Functions: regulates and controls body functions 2 Major Cell Types: Neurons - specialized nerve cells that generate and conduct nerve impulses Neuroglia - Supporting cells that support, insulate, and protect neurons |
|
|
Hyaline Cartilage - Flexible, yet rigid. Appears glassy - Lots of collagen fibers in the matrix, not visible because the optical density is the same as the matrix Location: ends of long bones, tracheal rings, larynx, costal (rib) cartilages, nose, most of the embryonic skeleton |
|
|
Hyaline Cartilage |
|
|
Transitional Epithelium - 3 to 6 layers of cells that have the ability to change shape - Cells appear cube shaped or columnar with domed shaped apical surfaces - When distended (bloated), cells appear flattened Major Function: Stretch Location: Urinary bladder, ureters, part of the urethra. Allows more urine to be stored in the urinary bladder |
|
|
Transitional Epithelium |
|
|
Elastic Cartilage |
|
|
Elastic Cartilage - Lots of elastin fibers. Strength and ability to stretch. Location: external ear and epiglottis (thing that hangs in back of throat) |
|
|
Blood - Is a fluid (Most atypical CT. No support or binding) - Consists of blood cells surrounded by a nonliving fluid matrix - Plasma - Red blood cells are most common cell type - Also contains white blood cells and platelets (cell fragments - pinched off portions of cell, initiate clot formation) Functions: in transport - O2, CO2, nutrients, wastes, hormones, etc...) |
|
|
Blood |
|
|
Cardiac Muscle - Found in the walls of heart, involuntary, one nucleus per cell, branching cells, striated, intercalated discs |
|
|
Cardiac Muscle |
|
|
Smooth Muscle - Nonstriated, involuntary, one nucleus per cell, tapered ends of cells - Location: mainly in walls of hollow organs such as the stomach and intestine |
|
|
Smooth Muscle |
|
|
Areolar Connective Tissue Loose connective tissue Functions: Supports and binds other tissues. The most widely distributed connective tissue |
|
|
Areolar Connective Tissue |
|
|
Stratified Squamous Epithelium |
|
|
Stratified Squamous Epithelium |
|
|
Stratified Squamous Epithelium - Most widespread of stratified epithelia - Free surface squamous; deeper layers cuboidal or columnar - Located in areas subject to wear and tear - Cells farthest from basal layer (and nutrients) are less viable Major Functions: Protect Location: External part of the skin and extends a short distance into every body opening that is directly continuous with the skin. |
|
|
Stratified Squamous Epithelium |
|
|
Dense Regular Connective Tissue |
|
|
Dense Regular Connective Tissue - Closely packed bundles of collagen fibers running parallel to the direction of pull - Location: tendons and ligaments |
|
|
Simple Columnar Epithelium Major Functions: absorption and secretion Location: Lines the digestive tract from the stomach through the rectum - May have microvilli, cilia, goblet cells, or tubular glands |
|
|
Simple Columnar Epithelium |
|
|
Elastic Connective Tissue |
|
|
Elastic Connective Tissue Dense connective tissue - Contains a high proportion of elastic fibers. Allows tissues to recoil after stretching - Location: walls of large arteries and bronchial tubes, certain ligaments |
|
|
Elastic Connective Tissue |
|
|
Skeletal Muscle - Contractible, little to no matrix, highly vascularized - Attached to bones of the skeleton, voluntary, striated. Multinucleate cells are called muscle fibers |
|
|
Skeletal Muscle |
|
|
Pseudostratified Columnar Epithelium - One layer but looks like many layers of columnar cells - Cells vary in height with cell nuclei at different levels - All cells reach the basement membrane, but not all reach the free surface - May have cilia and goblet cells Major Functions: Secretion and absorption Location: Upper respiratory tract, male's sperm carrying ducts |
|
|
Pseudostratified Ciliated Columnar Epithelium |
|
|
Compact Bone Tissue Also called osseous tissue. Very hard. Solid matrix. - Supports and protects body structures - Cavities in bone are the site of blood production and storage sites for fat. - Osteocytes are located in lacunae - Good blood supply - looks solid to the naked eye Location: in shafts of long bones and outside of all bones |
|
|
Compact Bone Tissue |
|
|
Dense Irregular Connective Tissue - Closely packed bundles of collagen fibers, but bundles are thicker and irregularly shaped - Location: in the dermis of the skin, sclera aka part of eye, joint capsules, and coverings around some organs |
|
|
Dense Irregular Connective Tissue |
|
|
Fibrocartilage - Alternating rows of chondrocytes and rows of collagen fibers - Compressible and resists tension - Location - intervertebral discs, pubic symphysis, menisci of knees |
|
