- 1. Tissues Epithelial, Connective , Nervous , Muscle , Credits Group of cells that are similar in structure and function. Study of tissues is known as Histology There are four basic types of tissues: Epithelial, Nervous, Connective, and Muscle
- 2. Epithelium Sheet of cells that cover body surface or lines body cavities Forms boundary between inner and outer environment Protects, absorbs, filtrates, and excretes Home , Simple , Stratified
- 3. Simple Epithelia Composed of a single layer of cells Functions include: absorption, secretion, and filtration Classified by shape: Squamous, Cuboidal, and Columnar Home , Stratified , Squamous Cuboidal , Columnar
- 4. Simple Squamous Epithelium Single thin layer of laterally flattened cells Simplest of the epithelial Found where filtration and exchange of substances is a priority Home , Simple , Cuboidal , Columnar
- 5. Endothelium inner covering of simple epithelium Located in capillaries Helps exchange nutrients and waste Home , Epithelium , Simple Squamous
- 6. Simple Cuboidal Consists of cube shaped single layer of cells Important for secretion and absorption Large spherical central nuclei Found in kidneys, ducts of small glands, and ovary surface Epithelium , Home , Simple ,
- 7. Simple Columnar Epithelium Single layer of column shaped cells with oval nuclei Function is to absorb and secrete Some have cilia which enables movement of particles Found in bronchi, uterine tubes, and uterus Home , Squamous , Cuboidal
- 8. Pseudostratified columnar Single layer of cells varying in height May give false impression of several layers Secretes and absorbs Lines the trachea of the respiratory tract Home , Simple , Stratified
- 9. Stratified Squamous Epithelium Several layers of flattened cells Thick and well-suited for protection Subjected to much abrasion Forms the epidermis of the skin Home , Simple , Cuboidal Columnar
- 10. Stratified Squamous Epithelium Several layers of flattened cells Thick and well-suited for protection Subjected to much abrasion Forms the epidermis of the skin Home , Simple , Cuboidal Columnar
- 11. Stratified Cuboidal Consists of two layers of cube shaped cells Rarely found in the body Found sometimes in glands
- 12. Stratified columnar epithelium Several layers of column shaped cells Limited distribtution throughout the body Found in some sweat and mammary glands Typically two cell layers thick Home , Cuboidal , Squamous
- 13. Transitional Epithelium Resembles stratified squamous Stretches with the organ it lines Found in urinary bladder, urethra, and uterus Home , Simple , Stratified
- 14. Glandular Epithelium One or more cells that secrete and make certain products Mostly classified by the site of release Either exocrine or endocrine Home, epithelial,
- 15. Endocrine Often called ductless glands Produce hormones Secretion produces amino acids, proteins and steroids Home, epithelium, glandular, exocrine
- 16. Exocrine Secretes their products onto body surface or into body cavities Transports secretion to epithelial surface Includes mucous, sweat, oil, and salivary glands Home, epithelium, glandular, endocrine
- 17. Unicellular and multicellular exocrine glands Produces mucin Contains goblet cells Structurally complex Supported by connective tissue Classified as simple or compound Home, epithelium, glandular, exocrine
- 18. Connective Tissue Consists of connective tissue proper, cartilage, blood, bone Binds, supports, protects, and insulates Have a common origin, a degree of vascularity, and an extracellular matrix Home, cartilage, bone, blood, tissue proper
- 19. Blood Fluid within the blood vessels Develops from mesenchyme Classified into red and white blood cells Transports nutrients Home, Connective tissue
- 20. Muscle Tissue Highly cellular tissues Responsible for most of the body's movements Contains myofilaments Three types: cardiac, skeletal, and smooth Home, Connective tissue, Smooth, Cardiac, Skeletal
- 21. Skeletal Muscle Long cylindrical cells with striations Controls and initiates voluntary movements Found attached to bone Home, Connective Tissue, Muscular Tissue, Smooth Muscle, Cardiac Muscle
- 22. Cardiac Muscle Found only among the walls of the heart Contracts and propels blood into the body Tissues are branched and striated Home, Connective tissue, Smooth, Skeletal Muscular
- 23. Smooth Muscle Has no visible striations Spindle shaped One central nuclei Found in hollow organs contracting and squeezing Home, Connective Tissue, Cardiac Muscle, Skeletal Muscle, Muscle Tissue
- 24. Nervous Tissue Main component of brain, spinal cord, and nerves contains neurons transmits electrical signals to effectors Home, Connective Tissue
- 25. Bone Also known as osseous tissue Able to support bodily structure Stores marrow, calcium, and minerals Home, Connective Tissue
- 26. Cartilage Tough but flexible Avascular and lacks nerves fibers Chondroblast produces new matrix until skeleton stops growing Home, Connective Tissue
- 27. Hyaline Cartilage Most abundant of all the cartilages Amorphous matrix, firm with imperceptible network of fibers Supports, reinforces, and cushions Home, Connective Tissue, Cartilage
- 28. Elastic Cartilage Identical to hyaline cartilage Has more elastic fibers Maintains structure and shape with flexibility Home, Connective tissue, Cartilage,
- 29. Fibrocartilage Similar to hyaline cartilage Found where support is most needed due to heavy pressure Contains rows of chondrocytes Home, Connective Tissue, Cartilage
- 30. Connective Tissue Proper Contains two substances: Loose and dense connective tissue Home, Connective Tissue, Loose, Dense
- 31. Connective tissue proper: Loose aerolar Wraps and cushions organs Holds and conveys tissue fluids Widely distributed Has a gel-like matrix Home, Connective Tissue, Adipose, reticular, Dense
- 32. Loose Connective Tissue: Adipose Similar matrix to aerolar with closely packed adipocytes Insulates, supports, and protects Found under the skin Home, Connective tissue, aerolar, reticular, dense
- 33. Loose connective tissue: reticular Loose ground substance Reticular fibers lying in the same network Supports other cell types Home, Connective Tissue, aerolar, dense, adipose, dense
- 34. Dense Connective Tissue: Regular Made of mostly fibers Contains fibrous connective tissue Attaches bone to muscle or muscle to bone Found in tendons Home, Connective Tissue, Loose, Irregular
- 35. Dense connective tissue: Irregular Contains thick bundles of collagen fibers Provides structural strength Able to withstand tension Home, Connective tissue, Dense regular, Loose
