Epithelium

Simple Squamous Epithelium

A single layer of flat cells that facilitates diffusion and filtration.

Stratified Squamous Epithelium

Multiple layers of flat cells that protect underlying tissues in areas subject to abrasion.

Simple Cuboidal Epithelium

A single layer of cube-shaped cells, ideal for secretion and absorption.

Stratified Cuboidal Epithelium

Multiple layers of cube-shaped cells found in some glands.

Simple Columnar Epithelium

A single layer of tall, column-like cells that absorb nutrients and secrete mucus.

Stratified Columnar Epithelium

Multiple layers of column-like cells; rare, found in male urethra.

Pseudo-stratified Ciliated Columnar Epithelium

Appears to have multiple layers, contains cilia; found in the respiratory tract.

Transitional Epithelium

A stratified epithelium that can stretch, found in the bladder.

Mesenchyme Connective Tissue

Embryonic connective tissue that gives rise to all other connective tissues.

Areolar Connective Tissue

Loose connective tissue that cushions organs and provides support.

Reticular Connective Tissue

Connective tissue that supports organs and lymphatic structures with a network of reticular fibers.

Adipose Connective Tissue

Specialized connective tissue that stores fat and insulates the body.

Dense Regular Connective Tissue

Connective tissue with parallel collagen fibers, found in tendons and ligaments.

Dense Irregular Connective Tissue

Connective tissue with irregularly arranged collagen fibers, providing strength in multiple directions.

Elastic Connective Tissue

Connective tissue containing a high proportion of elastic fibers, allowing for stretch and recoil.

Hyaline Cartilage Connective Tissue

The most common type of cartilage, providing support and flexibility.

Elastic Cartilage Connective Tissue

Cartilage containing elastic fibers; maintains shape while allowing flexibility.

Fibrocartilage Connective Tissue

Strong cartilage containing dense collagen fibers, found in intervertebral discs.

Bone Connective Tissue

Hard, dense connective tissue forming the skeleton.

Blood Connective Tissue

Fluid connective tissue that transports nutrients, gases, and wastes.

Skeletal Muscle Tissue

Striated muscle under voluntary control, responsible for movement.

Smooth Muscle Tissue

Involuntary muscle found in walls of hollow organs, not striated.

Cardiac Muscle Tissue

Striated muscle found only in the heart, involuntary and responsible for pumping blood.

Nervous Tissue

Tissue composed of neurons and supporting glial cells, for communication and signaling.

Neural Tissue

Tissue that makes up the brain, spinal cord, and nerves, responsible for transmitting impulses.
