What are the four types of tissue? - ANSWER: Epithelial, Connective, Muscle and
Nervous
A tissue type composed of epithelial cells and a thin basal layer of extracellular
matrix; functions to cover and line all body surfaces and hollow organs. It's
functions include protection, immune defence, secretion, transport into other
tissues and sensation. - ANSWER: Epithelial Tissue
A type of tissue characterized by extensive extracellular matrix; functions in
support, protection, and transport. - ANSWER: Connective Tissue
A tissue type composed of cells that can contract and generate force, with little
ECM between the cells. - ANSWER: Muscle tissue
A tissue type that makes up most of the brain, spinal cord, and peripheral nerves
that is composed of neurons, neuroglial cells, and a specialized extracellular
matrix. - ANSWER: Nervous Tissue

The substance in a tissue outside of the cells that consists of extracellular fluid,
ground substance, and protein fibers. - ANSWER: Extracellular matrix
An amorphous component of the extracellular matrix containing water,
proteoglycans, glycosaminoglycans, and other substances. - ANSWER: Ground
Substance
A carbohydrate attached by a covalent bond to a polypeptide or protein. -
ANSWER: Glycoprotein
Protein fibers in the extracellular matrix of a tissue that are composed of the
protein collagen and give a tissue tensile strength. - ANSWER: Collagen Fibres
Protein fibers in the extracellular matrix of a tissue that give a tissue distensibility
and elasticity. - ANSWER: Elastic Fibres
Thin protein fibers in the extracellular matrix of a tissue that form "nets" within
organs such as the spleen and lymph nodes and form supportive networks around
blood vessels and nerves. - ANSWER: Reticular Fibres
Two layers of extracellular matrix—the basal lamina and the reticular lamina—that
anchor an epithelial tissue to the underlying connective tissue. - ANSWER:
Basement membrane
, 3|Page
The extracellular matrix of epithelial tissue; composed primarily of ground
substance and collagen fibers. - ANSWER: Basal Lamina
What three basic shapes can epithelial cells take? - ANSWER: Squamous,
cuboidal and columnar
A type of epithelial tissue composed of a single layer of epithelial cells and the
underlying basal lamina. - ANSWER: Simple Epithelial
A type of epithelial tissue composed of two or more layers of epithelial cells and
the underlying basal lamina. - ANSWER: Stratified Epithelial
What are the four types of simple epithelial tissue? - ANSWER: Simple
squamous, simple cuboidal, simple columnar and pseudostratified columnar
A single layer of squamous epithelial cells and the underlying basal lamina;
provides a barrier that gases and fluids can be exchanged; found in locations such
as the alveoli of the lungs, the kidneys, and lining the inner surface of blood
vessels. - ANSWER: Simple Squamous Epithelium
A single layer of cuboidal epithelial cells and the underlying basal lamina;
Involved with absorption and secretion of mucus and other substances; found in
