Histology

Simple Columnar Epithelium

single layer of tall cells

secretion and absorption

found in the small intestine

Transitional Epithelium Tissue

Resembles both stratified squamous and stratified cuboidal

Stretches readily permits stored urine to distend urinary organ

Found in the bladder

Psuedostratified Ciliated Colummar

Epithelium

Single layer of cells of differing heights with cilia

Secrete substances

Located in the trachea

Simple cuboidal epithelium

Single layer of cube like cells with large nuclei

Secretion and absorption

Found in the kidneys and glands

Loose (areolar) Connective tissue

Provides support and elasticity

Composed of a gel-like matrix with collagen and elastin fibers.

Serves as a binding tissue and wraps around organs, blood vessels, and nerves.

blood connective tissue

Composed of red and white blood cells suspended in plasma.

Fluid ECM

It plays a crucial role in transportation, immunity, and homeostasis.

Located in blood vessels

Fibrocartilage connective tissue

Cells sitting in holes

Wavy background “blue”

Strength

A tough, flexible type of cartilage that provides support and absorbs shock. It is found in intervertebral discs, pubic symphysis, and menisci in the knee.

Reticular connective tissue

A type of connective tissue that forms a supportive framework for organs, composed of a network of reticular fibers and cells. It is commonly found in lymphoid tissues, bone marrow, and the spleen.

Adipose Tissue

A type of connective tissue that stores fat, providing insulation and energy storage. It is located beneath the skin in breasts

Dense regular collagenous connective tissue

a type of connective tissue characterized by closely packed parallel collagen fibers, providing tensile strength in one direction. It is commonly found in tendons and ligaments.

Avascular (takes a long time to heal)

Dense irregular connective tissue

a type of connective tissue characterized by collagen fibers arranged irregularly, providing strength in multiple directions.

It is found in the dermis

Elastic cartillage connective tissue

Cells sitting in holes

Short black fibers in ECM

Flexibility

a type of connective tissue containing a high concentration of elastic fibers

found in structures such as the ear and epiglottis.

bone connective tissue

a type of connective tissue that provides structural support and protection for organs

Solid ECM

It plays a key role in the skeletal system and houses bone marrow.

Skeletal muscle

a type of muscle tissue that is striated (banding) and under voluntary control. It is responsible for the movement of the skeleton and is composed of long, multinucleated fibers.

cardiac muscle

Branching striated with intercalated discs

pumps blood through the body

located in the walls of the heart

Neuron Nervous tissue

neurons transmit electrical signals

located in brain spinal cord and nerves

Stratified squamous epithelium

several layers of

protects tissues

located in esophagus

Hyaline cartilage connective tissue

Cells sitting in holes

Glossy/hazy ECM

Strength and flexibility

located in the cartilage of the ribs

Simple squamous epithelium

single layer of flattened cells Allows

allows materials to pass through diffusion

located in lungs

Smooth muscle

spindle shaped with central nuclei

Non striated

propels substances

in the walls of hollow organs (digestive)
