Histology is the study of the microscopic structure of tissues.
epithelial, connective, muscle, and nervous tissues.
Epithelial tissue covers body surfaces, lines cavities, has closely packed cells, and functions in protection, absorption, secretion, and filtration.
Connective tissue supports and binds other tissues, has cells scattered in an extracellular matrix of fibers and ground substance.
Muscle tissue is specialized for contraction, enabling movement; it includes skeletal, cardiac, and smooth muscle types.
Nervous tissue transmits electrical impulses and consists of neurons and neuroglial cells for support.
Single layer of flat cells; allows diffusion and filtration; found in lungs and blood vessels.
Multiple layers of flat cells; protects against abrasion; found in skin and mouth lining.
Single layer of cube-shaped cells; functions in secretion and absorption; found in kidney tubules and glands.
Single layer of tall cells with cilia; moves mucus; found in respiratory tract and fallopian tubes.
Single layer of tall cells with microvilli and goblet cells; absorbs nutrients and secretes mucus; found in digestive tract.
Single layer of cells appearing stratified, with cilia; traps and moves particles; found in respiratory tract.
Multiple layers of cells that stretch; found in urinary bladder to allow expansion.
Collagen fibers provide strength, elastin fibers provide elasticity, and reticular fibers form supportive networks.
A cell in connective tissue that produces fibers and ground substance of the extracellular matrix.
Loose areolar, adipose, and reticular tissues; they provide support, store fat, and form a soft internal skeleton.
Dense irregular and dense regular connective tissues; provide strong attachment and resist tension.
Contains chondrocytes in lacunae; provides smooth surfaces for joints; found in nose, trachea, and ends of long bones.
Contains elastin fibers; provides flexible support; found in ear and epiglottis.
Contains thick collagen fibers; resists compression; found in intervertebral discs and knee menisci.
Contains osteocytes in lacunae, arranged in lamellae around central canals; provides structural support and protection.
Blood has cells suspended in a liquid extracellular matrix (plasma) and connects body systems by transporting substances.
Erythrocytes (red blood cells) carry oxygen, leukocytes (white blood cells) fight infection, and thrombocytes (platelets) aid clotting.
Neurons transmit signals; neuroglial cells support and protect neurons.
Striated, multinucleated, voluntary muscle attached to bones for movement.
Striated, involuntary muscle with intercalated discs; found only in the heart.
Non-striated, involuntary muscle found in walls of hollow organs like intestines and blood vessels.
