Cells that can only divide under special conditions, like some nerve cells after injury.

Cells specialized in producing and secreting specific substances like hormones or enzymes.

The process of regulating gene expression to create diverse cell types from a single genome.

Star-shaped bone cells responsible for maintaining bone tissue.

Bone cells that synthesize new bone matrix, forming the structural framework.

Stem cells that differentiate into osteoblasts, found on the outer surface of bones.

Large, multinucleated cells responsible for breaking down bone tissue for remodeling.

Immune system cells that defend the body against pathogens, each subtype with a specific role.

White blood cells that engulf and destroy pathogens in tissues.

White blood cells that attack larger parasites and trigger allergic responses.

White blood cells that release histamines, involved in inflammation.

White blood cells that include B cells and T cells, responsible for immune responses.

White blood cells that produce antibodies against non-self-antigens, key for adaptive immunity.

White blood cells that destroy virus-infected cells and cancer cells, essential for cell-mediated immunity.

The most numerous white blood cells, responsible for phagocytizing bacteria and fungi in the blood.

Groups of connected cells that work together to carry out specific functions.

A type of tissue that provides support and structure to the body, holding cells together.

The non-cellular material that surrounds connective tissue cells, determining its characteristics.

Connective tissue that consists of various fibers embedded in a gel-like matrix, connecting skin to underlying tissues.

Connective tissue specialized for storing fat for energy and providing insulation.

Connective tissue composed of reticular fibers that form a supportive framework for organs, found in the lymphatic system.

Connective tissue with densely packed fibers arranged in parallel bundles, providing strength and support.

Connective tissue with fibers arranged in different directions, providing resistance to stress from multiple angles.

Connective tissue composed of elastic fibers that allow for stretching and recoil, found in the walls of arteries.

A type of connective tissue that provides support and flexibility, consisting of chondrocytes embedded in a matrix.

The most common type of cartilage, found in the nose, ribs, and trachea, providing flexibility and support.

Cartilage with elastic fibers in the matrix, allowing for bending and maintaining shape, found in the ears and larynx.

Tough cartilage containing many collagen fibers, found in the knee joint and vertebral discs, resisting compression.

Hard, mineralized connective tissue that forms the skeletal framework, providing support and protection.

Mature bone cells located in lacunae within the bone matrix, responsible for maintaining bone tissue.

Liquid connective tissue that transports oxygen, nutrients, and waste products throughout the body.

The liquid extracellular matrix of blood, composed of water, salts, and dissolved proteins.

Red blood cells that carry oxygen from the lungs to the body's tissues.

White blood cells responsible for defending the body against pathogens.

Cell fragments involved in blood clotting, forming a plug to stop bleeding.

Tissue that forms coverings or linings of organs and cavities, characterized by tightly joined cells.

Specialized junctions between epithelial cells that create a tight seal, preventing leakage and pathogen entry.

Muscle tissue that is striated, attaches to bones, and allows for voluntary movement.

Muscle tissue that is non-striated, found in blood vessels and internal organs, and responsible for involuntary movement.

Muscle tissue that is striated, found only in the heart, and responsible for pumping blood.

Tissue composed of neurons and glial cells, responsible for transmitting electrical impulses and supporting the nervous system.

Nervous tissue containing the cell bodies of neurons, found in the brain and spinal cord, responsible for information processing.

Nervous tissue containing myelinated axons of neurons, found in the brain and spinal cord, responsible for connecting and transmitting information.

Bundles of axons that transmit electrical impulses from the central nervous system to the rest of the body.

Clusters of neuron cell bodies located outside the central nervous system, acting as relay points for nerve impulses.

Plant tissue covering the outer surface of a plant, providing protection and mediating interactions with the environment.

Waxy substance secreted by epidermal cells that waterproofs and protects above-ground plant parts.

Tiny pores on the surface of leaves that control the exchange of gases and water vapor.

Cells that make up the majority of the epidermis, lacking chloroplasts.

Hair-like structures on the epidermal surface that help reduce water loss, reflect sunlight, and defend against herbivores.

Plant tissue that makes up the interior of a plant, performing basic metabolic functions like photosynthesis and food storage.

Specialized ground tissue in leaves that carries out photosynthesis.

Ground tissue in stems that provides support and may store food or water.

Ground tissue in roots that often stores energy-rich carbohydrates.

Plant tissue that transports water, minerals, and nutrients throughout the plant, consisting of xylem and phloem.

Vascular tissue that carries water and dissolved ions from the roots to the stems and leaves.

Vascular tissue that carries dissolved sugars from the leaves to other parts of the plant.
