Morfofisiologia Básica - Tecido Epitelial

A group of cells that share similar characteristics and work together to perform a specific function.

The four main types of tissues found in the body, each with a unique structure and function.

The largest organ in the human body, composed of three distinct layers.

The outermost layer of skin, responsible for protection and acting as a barrier against external threats.

The middle layer of skin, containing blood vessels, nerves, and glands.

The deepest layer of skin, composed mainly of fat cells and providing insulation and cushioning.

A type of tissue made up of closely packed cells with little space between them, forming a protective barrier.

The characteristic that describes epithelial cells as having many sides, resembling a polyhedron.

The limited presence of the material that fills the spaces between cells in epithelial tissue.

The lack of blood vessels within epithelial tissue, relying on diffusion from underlying tissues for nutrients.

The ability of epithelial tissue to regenerate quickly after injury, crucial for its protective function.

The type of epithelial tissue that covers surfaces, providing a protective barrier.

The type of epithelial tissue that is responsible for producing and secreting substances.

The vital role played by epithelial tissue in safeguarding the body from external threats.

The ability of epithelial tissue to absorb essential molecules from the environment, exemplified by the small intestine.

The role of epithelial tissue in facilitating the transport of molecules and perceiving external stimuli, evident in areas like taste buds.

The process by which epithelial cells, especially those in glandular epithelium, release substances.

Specialized epithelial cells that contract, aiding in the expulsion of secretions, found in glands.

A type of epithelium with a single layer of cells, providing a thin and delicate barrier.

A type of epithelium with multiple layers of cells, offering robust protection.

A type of epithelium that appears to have multiple layers due to varying cell heights, but is actually a single layer.

A type of epithelium that lines the urinary tract, with cells that change shape depending on bladder distension.

The exposed surface of epithelial cells, interacting with the external environment.

Special structures that connect epithelial cells, ensuring their integrity and communication.

A type of intercellular junction that provides strong adhesion between epithelial cells.

A type of intercellular junction that creates a tight seal between epithelial cells, preventing leakage.

Finger-like projections extending from epithelial cells, increasing surface area for absorption, found in the small intestine.

Hair-like structures extending from epithelial cells, aiding in the movement of molecules, found in the respiratory tract.

Glands that release their secretions outside the body or into cavities, like the stomach.

Glands that directly release their secretions into the bloodstream, like the thyroid.

Glands that perform both exocrine and endocrine functions, like the pancreas.

Glands that produce watery, protein-rich secretions, like digestive enzymes.

Glands that produce thick, viscous secretions, like mucus.
