• Tissues are group of cells that are similar structures and perform specific functions.
• Histology is the study of tissues and organs at a microscopic level.
• Epithelial tissues coating the body surface, lining the body cavities, and forming glands
• Squamous cells are flat cells that are found in the epidermis.
• Simple Squamous cells are found in lung alveoli and are the most common type of cell in the body
• Stratified squamous cells are found in skin, mouth and vagina.
• Cuboidal epithelium has cube-shaped cells with rounded edges and is found in ducts of salivary gland, kidney tubules, and ovarian follicles.
• Columnar epithelium has tall column-like cells with pointed tops and is found in stomach, intestines, uterus, and fallopian tube.
• Transitional epithelium is found in the lining of the urinary bladder and the lining of the small intestine
• Connective tissue provides support to other organs and structures within the body.
• The ground substance is made of an organic matrix and a water-soluble matrix
• The ground substance is made of an organic substance (usually protein) and an inorganic substance (usually water or mineral).
• Principal cell of connective tissue is the fibroblast, which is a type of cell that produces collagen and elastin.
• Macrophages, lymphocytes and other leukocytes are all white blood cells and can be fpund in some tisssues.
• The matrix in connective tissues give the tissue its density and strength.
• Collagen Fibers provide strength to the tissue and prevents it from tearing apart.
• Collagen Fibers can be found in tendons, ligaments, and bones.
• Elastic Fibers are made of the protein elastin and are found in the walls of blood vessels and the walls of the heart
• Elastic fibers can stretch to one and one half times their original length and then return to their original length
• Reticular Fibers are thin and fine and form a network that supports organs such as the liver and spleen
• Reticular fibers are wound healing and helps in scar tissue formation
• Loose or Areolar cells are fibroblasts, macrophages, some lymphocytes, and some neutrophils.
• Areolar connective tissue is found beneath the skin (dermis) and around internal organs
• Fibers in Loose or Areolar tissues are collagen, elastin, and reticular.
• Dense Fibruous Connective tissue cells are fibroblasts, macrophages, and fibrocytes
• Dense Fibrous connective tissue is found in tendons, ligaments, and aponeuroses
• Fibers in Dense Fibrous Tissue are Collagen
• Cells in the cartilage are specialised for the production of chondrocytes
• Hyaline Cartilage are most common
• Hyaline Cartilage lines your joints and caps the end of your bones.
• Hyaline Cartilage is slippery and smooth it helps your bones move over each other
• Hyaline Cartilage is usually found in the nose, trachea, and bronchi
• Fibrocartilage is tough cartilage made of thick fibers of collagen.
• Fibrocartilage is the strongest and least flexible type of cartilage.
• Firocartilage holds parts of the body together and is found in the joints
• The location of fibrocartilage is the joints, tendons, and ligaments
• Elastic Cartilage is found in the ear canal and epiglottis
• Elastic cartilage has elastin fibers that allow it to stretch and return to its original shape
• Elastic Cartilage supports parts that need to bend or move to function properly.
• Bone cells are called osteoblasts and osteoclasts
