histo

Simple Squamous Epithelium

A single layer of thin, flat cells; allows easy diffusion and filtering.

Cuboidal Cell

Cell shape resembling a cube; often found in glandular tissues, involved in secretion and absorption.

Columnar Cell

Tall, column-like cells that may have cilia or microvilli, aiding in absorption and movement.

Pseudostratified Epithelium

Appears layered due to nuclei at different levels but is a single layer, often ciliated.

Stratified Squamous Epithelium

Multiple layers of flat cells, providing protection against abrasion and pathogens.

Stratified Cuboidal Epithelium

Two or more layers of cube-shaped cells; found in sweat and salivary glands.

Transitional Epithelium

Multiple layers of cells that can change shape; allows stretching in the urinary bladder.

Loose Areolar Connective Tissue

Loose arrangement of fibers, provides support and elasticity to tissues.

Dense Regular Connective Tissue

Densely packed collagen fibers arranged in parallel; provides tensile strength.

Reticular Connective Tissue

Network of reticular fibers that supports the structure of soft organs.

Elastic Connective Tissue

Connective tissue rich in elastic fibers, allows for stretching and recoiling.

Red Blood Cells (Erythrocytes)

Biconcave, anucleated cells that transport oxygen and carbon dioxide.

White Blood Cells (Leukocytes)

Cells of the immune system that defend the body against infections.

Platelets (Thrombocytes)

Cell fragments involved in blood clotting and wound healing.

Astrocytes

Star-shaped glial cells that support neurons and maintain the blood-brain barrier.

Oligodendrocytes

Glial cells that produce myelin sheaths in the central nervous system.

Microglia

Immune cells in the CNS that act as macrophages to remove debris.

Ependymal Cells

Ciliated cells that produce and circulate cerebrospinal fluid.

Gray Matter

Regions of the CNS with neuron cell bodies; processes information.

White Matter

Regions of the CNS with myelinated axons that transmit signals.

Hyaline Cartilage

Smooth, glassy cartilage providing support and reducing friction.

Elastic Cartilage

Cartilage containing elastic fibers, providing strength and elasticity.

Fibrocartilage

Cartilage with thick collagen fibers, providing strong support and shock absorption.

Osseous Tissue (Bone)

Hard bone tissue providing structural support and mineral storage.
