what are the 4 basic connective tissues
Epithelial tissue
Connective tissue
Nervous tissue
Muscle tissue
what is epithilial tissue
Epithelial tissue (includes epithelia and glands) covers surfaces, lines cavities, and forms
secretory glands.
The cells in epithelial tissue are usually arranged in one or more layers, very
close together, and with very little extracellular matrix.
What are three examples of epithelial tissue in the human body?
Skin, passageways in the kidneys, inside the eye, at the gas exchange surfaces (alveloi) of
the lungs + MANY OTHERS!
(Epithelium)
what is the name of a single layer of cells
simple epithelium
(Epithelium)
what is the name of a multi layer cells
stratified epithelium
(Epithelium)
what cells are thin and flat
Squamous
(Epithelium)
what cells appear like boxes or cube-like shapes
cuboidal
what cells are taller and
relatively slender rectangles.
columnar
what is and the function of connective tissue
it supports the body and varies widely in appearance and function. Connective tissue holds parts together, transports substances, and protects the body from foreign invaders.
what kind of tissue is a bond?
connective tissue
what kind of tissue is the blood
connective tissue
what is Adipose tissue
its specilised connective tissue primarily composed of fat cells that store energy in the form of triglycerides
What type of sensation do Pacinian Corpuscles detect, and why might they be present in the
finger?
These receptors sense pressure and vibration - which you can imagine is important for the
“touch” sensation necessary for a finger to have. It allows you to know how hard or soft a
surface that you’re touching might be, or how much pressure you’re applying to something.
what is, and the function of nervous tissue
it’s the most complex tissue of the body and provides communication between
various parts of the body, and integrates activities between them. The brain and spinal cord
are the control centers of the nervous system and account for most of the nervous tissue in
the body (>95%).
List three examples of nervous tissue in the human body
Brain
spinal cord
nerves
what is the function of the muscle tissue
Movement is produced by muscle tissue, which is specialised for contraction.
what are the 3 types of muscle tissue
Skeletal muscle
Cardiac muscle
Smooth muscle
