Epithelial Tissue

A type of tissue that covers body surfaces and lines cavities and organs, characterized by closely packed cells.

Simple Epithelial Tissue

Consists of a single layer of cells.

Stratified Epithelial Tissue

Consists of two or more layers of cells.

Cuboidal Cells

Epithelial cells that are as tall as they are wide, resembling cubes.

Columnar Cells

Epithelial cells that are taller than they are wide, resembling columns.

Squamous Cells

Flat, scale-like epithelial cells.

Glandular Epithelial Tissue

Type of epithelial tissue responsible for the secretion of hormones and other substances.

Pseudostratified Epithelial Tissue

Appears layered due to varying cell heights but is actually a single layer; all cells rest on the basement membrane.

Tight Junctions

Connections that prevent leakage between epithelial cells.

Desmosomes

Structures that anchor adjacent epithelial cells together.

Exocrine Glands

Glands that release their products through ducts to the outside of the body or into a cavity.

Endocrine Glands

Glands that release hormones directly into the bloodstream without using ducts.

Connective Tissue

The most abundant tissue type in the body, characterized by an extracellular matrix that supports and binds other tissues.

Collagen

A protein fiber that provides strength to connective tissues.

Elastic Fibers

Protein fibers that allow connective tissues to stretch and recoil.

Reticular Fibers

Thin, highly branched fibers that form a supportive network in connective tissues.

Areolar Tissue

A type of loose connective tissue that contains a variety of cells and fibers in a gel-like matrix.

Adipose Tissue

Connective tissue that stores fat and provides insulation and cushioning.

Dense Regular Connective Tissue

Connective tissue made up of parallel collagen fibers that provides strength in one direction.

Fibrocartilage

A type of cartilage that is thick and resilient, designed to absorb shock.

Hyaline Cartilage

The most common type of cartilage, acting as a precursor to bone and found in growth plates.

Compact Bone

The dense and strong outer layer of bone tissue.

Skeletal Muscle Tissue

Voluntary, striated muscle responsible for movement of the skeleton.

Cardiac Muscle Tissue

Involuntary, striated muscle found in the heart.

Smooth Muscle Tissue

Involuntary muscle that is non-striated, found in the walls of hollow organs.

Neurons

Excitable cells that transmit electrical signals in the nervous system.

Neuroglia

Supporting cells in the nervous system that assist and protect neurons.
