Epithelial Tissue
microscopic extensions of the apical cell membrane that are supported by microtubules. They beat in unison and move fluids as well as trapped particles.
What are cilia
What is one function of connective tissue?
What is protection, support, connect other tissues, transport materials, store surplus energy
40% of your body mass is made up of this type of muscle tissue
What is skeletal muscle tissue
an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells
what is a Stem Cell
Programmed cell death is known as this. Cancer cells do not undergo this process.
What is apoptosis
These epithelial cells look stratified but are really just one layer of overlapping columnar cells
What is pseudostratified
The main example of fluid connective tissue is this
What is Blood
due to the regular alternation of the contractile proteins actin and myosin, along with the structural proteins that couple the contractile proteins to connective tissues, skeletal muscles cells appear to be this
Striated (striation)
they have the potential to differentiate into any of the cells needed to enable an organism to grow and develop.
What are totipotent stem cells
When cancer cells spread to parts of the body different from where they originated this is known as
These epithelial cells are found in the air sacs and lining of blood vessels. They allow materials to pass through by diffusion
Which cells store fat, and have a slower metabolic rate than their brown counter parts
What are White Adipose Cells
they contract on their own intrinsic rhythms without any external stimulation.
What is cardiac muscle
has the potential to differentiate into any type of human tissue but cannot support the full development of an organism
What is pluripotent
A normal cell undergoes this mechanism, which means when a cell comes in contact with a neighbor, it will stop dividing.
What is contact inhibition
These glands release their contents through a duct that leads to the epithelial surface.
Mucous, sweat, saliva, and breast milk are all examples of secretions from these glands
What is Exocrine Gland
What is the most abundant type of cartilage in the body
What is hyaline cartilage
responsible for involuntary movements in the internal organs.
It forms the contractile component of the digestive, urinary, and reproductive systems as well as the airways and arteries.
What is smooth muscle tissue
stem cell is limited to becoming one of a few different cell types.
What is Oligopotent
In order to supply the growing tumors with nutrients cancer cells promote this process of directing the growth of new blood vessels to the tumor
What is angiogenesis
Epithelium cells are described by two things
Number of Layers and Shape (of cells)
What is the most abundant cell type in connective tissue proper?
Hint: the second most abundant cell type is the fibrocyte
What are fibroblasts
A long “tail,” the axon, extends from the neuron body and can be wrapped in an insulating layer known as
Myelin, Myelin sheath
What is one source of stem cells that can be used in a lab experimentally
Human embryonic Stem Cells (HeSCs)
Adult Stem Cells (from bone marrow or skin)
Stem cells from umbilical cord blood
Stem cells from deciduous teeth (baby teeth)
Mutations that are cancer causing are known as
What are carcinogens
