Questions and Answers

List the four kinds of tissue.

Epithelial, Muscle, Nervous, Connective

What is epithelial tissue and its function?

The cells that line the external and internal surfaces of the body. It's nonvascular, receiving no direct blood supply. It provides protection as well as areas of absorption and secretion.

What is the basement membrane?

Made up of two layers; the basal lamina which is superficial to the lamina reticularis.

Study Notes

Types of Tissue

Four main types of tissue: Epithelial, Muscle, Nervous, Connective.

Epithelial Tissue

Epithelial tissue lines external and internal body surfaces; is nonvascular and lacks direct blood supply.
Functions include protection, absorption, and secretion.

Basement Membrane

Composed of two layers: basal lamina (superficial) and lamina reticularis (deeper).

Simple Squamous Epithelium

Locations: Air sacs of lungs, inner lining of heart, and blood vessels.

Simple Columnar Epithelium

Locations: Lines digestive organs including stomach, small intestine, large intestine, and uterus.

Simple Cuboidal Epithelium

Location: Lines kidney tubules and small ducts of many glands.

Pseudostratified Columnar Epithelium

Ciliated variant found in the trachea and upper respiratory tract; non-ciliated in the membranous part of the male vas deferens.
Contains cilia and goblet cells.

Transitional Epithelium

Location: Mucosal lining of ureters, urethra, and urinary bladder; capable of stretching.

Stratified Squamous Epithelium

Keratinized variant found in the outer layer of skin.
Non-keratinized variant found in vagina and mouth.

Connective Tissue

Functions to provide support and connect different body parts.

Areolar Connective Tissue

Function: Holds organs in place and attaches epithelial tissue to underlying tissues.
Location: Underneath nearly all epithelial tissue; nutrient exchange for most cells occurs here.

Reticular Connective Tissue

Composed of abundant reticular fibers that support organs.
Locations: Kidneys, lymph nodes, red bone marrow, and spleen.

Adipose Connective Tissue

Functions in insulation, mechanical protection, and energy storage.
Location: Surrounds major organs and is found in the subcutaneous layer of skin.

Dense Regular Collagenous Connective Tissue

Provides strength in a single plane.
Location: Forms tendons and ligaments, covering around bones, cartilage, and muscles.

Dense Irregular Collagenous Connective Tissue

Provides strength in multiple planes.
Location: Forms capsules surrounding internal organs such as the pericardium and renal capsule.

Elastic Connective Tissue

Function: Allows for stretch and recoil.
Location: Found in large blood vessels like the aorta and certain ligaments.

Hyaline Cartilage

Provides smooth surfaces for tissue movement.
Locations: Ends of long bones, nose, and ends of ribs attaching to sternum.

Fibrocartilage

Resists deformation under stress.
Locations: Vertebral discs and certain bone-ligament junctions.

Elastic Cartilage

Provides structural support with flexibility.
Locations: External ear and tip of the nose.

Bone Tissue

Functions: Muscle attachment, movement, support, and blood cell production.
Structure includes lacunae (housing osteocytes), central canal, canaliculi, and lamella.

Blood Tissue

Primary function: Nutrient and waste transport throughout the body.
Components: Erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets).

Neuron

Specialized cell of the nervous system responsible for information transmission.
Key components: Cell body with nucleus, dendrites, and axon.
