Micro Anatomy Flashcards
The structural unit of epithelium is the
cell
The structural units of connective tissue are
cells, fibres, matrix
The structural unit of muscle tissue is
the muscle cell
The structural unit of nervous tissue is the
neuron
How do you define the term “tissues?”
A group of cells that have a similar structure and that function together as a unit
What is the key function of epithelium?
Protective linings, secretion, and absorption
What are some of the key function of connective tissue? (4)
Connects/anchors, provides support, locomotion, repair
What is the key function of muscle tissue?
Movement
What is the key function of nervous tissue?
Generates, conducts impulses
What is the embryonic origin of epithelium? (Outer linings and skin?)
Ectoderm
What is the embryonic origin of the body’s inner linings?
Endoderm
What is the embryonic origin of connective tissue?
Mesoderm
What is the embryonic origin of muscle tissue?
Mesoderm
What is the embryonic origin of nervous tissue?
Ectoderm
The inner epithelial lining of blood and lymphatic vessels is known as
Endothelium
What are the functions of adipose tissue in the human body?
Insulation, protection, padding/support
What is the function of cartilage in the body?
Flexible support to skeleton, framework
Why is bone referred to as “modified connective tissue?”
The matrix is modified due to mineralisation
Which main body system is derived from ectoderm germ layer?
Nervous system (also integumentary system?)
Name the surface modifications of epithelium
Cilia, microvilli, cell junctions, glands
Define the term “gland”
A cell or group of cells modified to secrete chemical substances that are either released into its surroundings (exocrine glands) or directly into the bloodstream (endocrine glands)
