Involuntary, non-striated muscle found in walls of hollow organs like the stomach and intestines; moves food along.
Voluntary, striated muscle attached to bones; allows conscious body movements.
Involuntary, striated muscle with branched fibers and intercalated discs; found only in the heart to pump blood.
Made of neurons (conduct electrical signals) and neuroglia (support cells); found in brain, spinal cord, and nerves.
Single layer of flat cells; ideal for rapid filtration and diffusion; found in lungs (alveoli) and blood vessels.
Single layer of cube-shaped cells; specializes in secretion and absorption; found in kidney tubules and glands.
Single layer of tall cells lining digestive tract; absorbs nutrients; often has microvilli or mucus-secreting goblet cells.
Multiple layers of flat cells; protects against friction; forms outer skin layer, mouth, and esophagus lining.
Two or more layers of cube-shaped cells; rare; protects and secretes in ducts of large glands like sweat glands.
Multiple layers of tall cells; very rare; functions in protection and secretion in parts of pharynx and male urethra.
Single layer of tall cells with nuclei at different levels; often ciliated; found lining upper respiratory tract (trachea).
Specialized stratified cells that stretch from round to flat; found lining urinary bladder to allow expansion.
Hard, calcified matrix with osteocytes; supports body, protects organs, and stores calcium.
Fluid matrix (plasma) with red and white blood cells and platelets; transports nutrients, gases, and wastes.
Flexible cartilage with elastic fibers; provides shape and flexibility; found in external ear and epiglottis.
Glassy, smooth cartilage with hidden collagen fibers; reduces friction at joints; found on ends of long bones, nose, and trachea rings.
Shock-absorbing cartilage with thick collagen rows; very tough; found in intervertebral discs and knee meniscus.
Loose, web-like tissue with all three fiber types; acts as universal glue holding organs in place; found under all epithelial tissues.
Delicate network of reticular fibers; forms soft internal skeleton supporting free blood cells in lymphoid organs like spleen and lymph nodes.
Fat tissue with large fat cells (adipocytes); stores energy, insulates against heat loss, and cushions organs.
Parallel rows of tightly packed collagen fibers; withstands pulling force in one direction; forms tendons and ligaments.
Randomly arranged collagen fibers; withstands tension from many directions; found in dermis of skin and joint capsules.
Dense tissue dominated by elastic fibers; allows recoil after stretching; found in walls of large arteries and bronchial tubes.
