Tissue Types

Nervous (Spinal Cord)

Location: In peripheral nerves and in organs of the central nervous system, brain, and spinal cord.

Function: Receives stimuli and sends impulses to the spinal cord and Brain.

Appearance: Consists of neurons, dendrites, and axons that form a long line of connectivity.

Muscle

Skeletal Muscle

Location: Attached to the Skeleton.

Function: Moves the body.

Appearance: Is striated and conatins long, thin, multi nucleated fibres that are crossed with a regular pattern of fine red and white lines.

Cardiac Muscle

Location: Walls of the heart.

Function: Controls the contraction and relaxation of the heart.

Appearance: Contains bundles that are branched like a tree but is connected at both ends.

Smooth Muscle

Location: In the walls of hollow visceral organs.

Function: Controls involuntary movements.

Appearance: Contains small smooth muscle cells that our spindle shaped and have no striations but have bundles of thin and thick filaments.

Connective

Bone Tissue

Location: Throughout the body.

Function: Locomotion, support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow.

Appearance: Concentric rings of matrix that surround central canals that contain blood vessels that inside contain lacunae that are connected to each other through canalicula.

Blood Tissue

Location: Around every blood vessel.

Function: Transports Oxygen and Carbon Dioxide.

Appearance: Contains a fluid matrix and no fibers.

Fibrocartilage

Location: Between Vertebrae

Function: Shock absorber

Appearance: Tough, dense, and fibrous material.

Elastic Cartilage

Location: External Ear and Larynx.

Function: Greatly flexible to efficiently channel sound waves to the inner ear.

Appearance: Contains many yellow elastic fibers with chondrocytes that lie between them that appear dark.

Hyaline Cartilage

Location: Ends of joints, nose and respiratory passages.

Function: Shock absorber and reduces friction by serving as a padding between bones where they meet at joints.

Appearance: Glass-like but translucent with a pearl-grey color and a considerable amount of collagen with a firm consistency.

Fibrous

Location: Dermis of skin, tendons, and ligaments.

Function: Support

Appearance: Large amounts of collagen fibers and few cells or matrix material.

Adipose

Location: Subcutaneous fat, visceral fat, bone marrow, and breasts.

Function: Serves as a protective cushion, insulation to preserve body heat, and stores energy.

Appearance: Loose connective tissue composed of adipocytes.

Loose Connective or Areolar Tissue

Location: Skin, around mucous membranes, around blood vessels, nerves, and organs of the body.

Function: Binds underlying organs to skin and to each other and also forms delicate thin membranes throughout the body.

Appearance: Loose arrangement of collagenous and elastic fibers, scattered cells of various types; abundant ground substance; numerous blood vessels

Epithelial

Stratified Columnar

Location: Parts of the Eye, Pharynx, Anus, Uterus, Male Urethra, and Vas Deferens

Function: Protection and Secretion

Appearance: Column Shaped in Multiple Layers

Stratified Cuboidal

Location: Pancreatic Ducts and Salivary Glands

Function: Secretion and Protection

Appearance: Multiple Layers of Cubes

Glandular Epithelium

Endocrine and Exocrine Glands

Function: Secretion

Appearance: Stratified with Goblet Cells

Transitional Epithelium

Location: Urinary Bladder

Function: Blocks Diffusion

Appearance: Stretchable

Pseudostratified Columnar

Location: Air passages and Reproductive Tubes

Function: Secretion and Cilia-aided Movement

Appearance: Stratified Single Layer

Stratified Squamous

Location: Skin and Mouth

Function: Protection

Appearance: Tall and Flattened

Simple Columnar

Location: Digestive Tract and Uterus

Appearance: Column Shaped

Simple Cuboidal

Location: Kidneys, Tubules, Ducts, Ovaries

Function: Secretion and Absorption

Appearance: Cubed Shaped

Simple Squamous

Location: Air Sacs in Lungs, Capillaries

Function: Diffusion and Filtration

Appearance: Flat and Thin
