Epithelial, Connective, Muscle and Nervous answ✔️💜💜✔-What are the four types of tissue?
Epithelial Tissue answ✔️💜💜✔-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.
Connective Tissue answ✔️💜💜✔-A type of tissue characterized by extensive extracellular matrix;
functions in support, protection, and transport.
Muscle tissue answ✔️💜💜✔-A tissue type composed of cells that can contract and generate force,
with little ECM between the cells.
Nervous Tissue answ✔️💜💜✔-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.
,Extracellular matrix answ✔️💜💜✔-The substance in a tissue outside of the cells that consists of
extracellular fluid, ground substance, and protein fibers.
Ground Substance answ✔️💜💜✔-An amorphous component of the extracellular matrix containing
water, proteoglycans, glycosaminoglycans, and other substances.
Glycoprotein answ✔️💜💜✔-A carbohydrate attached by a covalent bond to a polypeptide or protein.
Collagen Fibres answ✔️💜💜✔-Protein fibers in the extracellular matrix of a tissue that are composed
of the protein collagen and give a tissue tensile strength.
Elastic Fibres answ✔️💜💜✔-Protein fibers in the extracellular matrix of a tissue that give a tissue
distensibility and elasticity.
Reticular Fibres answ✔️💜💜✔-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.
Basement membrane answ✔️💜💜✔-Two layers of extracellular matrix—the basal lamina and the
reticular lamina—that anchor an epithelial tissue to the underlying connective tissue.
Basal Lamina answ✔️💜💜✔-The extracellular matrix of epithelial tissue; composed primarily of ground
substance and collagen fibers.
Squamous, cuboidal and columnar answ✔️💜💜✔-What three basic shapes can epithelial cells take?
Simple Epithelial answ✔️💜💜✔-A type of epithelial tissue composed of a single layer of epithelial cells
and the underlying basal lamina.
Stratified Epithelial answ✔️💜💜✔-A type of epithelial tissue composed of two or more layers of
epithelial cells and the underlying basal lamina.
, Simple squamous, simple cuboidal, simple columnar and pseudostratified columnar answ✔️💜💜✔-
What are the four types of simple epithelial tissue?
Simple Squamous Epithelium answ✔️💜💜✔-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.
Simple cuboidal epithelium answ✔️💜💜✔-A single layer of cuboidal epithelial cells and the underlying
basal lamina; Involved with absorption and secretion of mucus and other substances; found in locations
such as the kidney tubules, many endocrine glands, and the ducts of many exocrine glands.
Simple Columnar Epithelium answ✔️💜💜✔-A single layer of columnar epithelial cells and the
underlying basal lamina; Involved in absorption and secretion of mucus and other substances; found in
locations such as lining the digestive tract and many other hollow organs.
Pseudostratified columnar epithelium answ✔️💜💜✔-A single layer of columnar epithelial cells and the
underlying basal lamina; the nuclei of the cells are uneven; secretes mucus and propels it with ciliary
motion; found in locations such as the lining of the nasal cavity and much of the respiratory tract.
Stratified squamous epithelium answ✔️💜💜✔-Several layers of squamous epithelial cells and the
underlying basal lamina; located in the oral cavity and esophagus, the anus, and vagina; involved in
protection from mechanical stresses and microorganisms.
Fibroblasts answ✔️💜💜✔-A cell type within connective tissue proper that produces components of
the extracellular matrix.
Adipocytes answ✔️💜💜✔-The main cell type in adipose tissue; each cell contains a large lipid droplet
in its cytoplasm.
Phagocytes answ✔️💜💜✔-A cell that ingests foreign cells, dead cells, and other cellular debris by
phagocytosis.
