Connective tissue
What are
Areolar-glue
Adipose-fat
Fibrous-collagen
Bone- matrix calcified
cartilage- matrix is rubbery
blood- matrix is fluid?
Bladder, trachea, glands, kidneys, lungs, blood vessels, esophagus, skin surface, lines body cavities
Where is epithelial tissue found?
Cell division is complete
What is Telophase?
Chromatin becomes organized
What is Prophase?
Active-requires cell energy (to drink. Used to bring fluids and solutes into the cell.
What is Pinocytosis?
Active transport mechanisms because they require cell energy (to eat). Example... Helps to destroy bacteria white blood cells.
What is Phagocytosis?
Skeletal, cardiac, smooth
List 3 types of muscle cells.
Voluntary movement
What is skeletal muscle?
involuntary (heart)
What is cardiac muscle?
Visceral, involuntary (contractions of digestive tract)
What is Smooth muscle?
Neurons
What is a conducting unit?
glia
What is a connecting and supporting cell?
Neurons and glia
What are two types of nerve cells?
Rapid communication between body structures and control of body functions.
What is the function of the nervous tissue?
Intercellular material found between the cells.
liquid form is in the blood
In bone it is calcified hard and rigid like rubber
Where is matrix found?
Areolar, adipose, fibrous connective tissue, bone cartilage, blood, hematopoietic tissue
What are 7 types of connective tissue?
The clearage furrow begins to appear. Chromatids move away from the center of the cell.
What happens during Anaphase?
Chromosomes are aligned in the center of the cell and nuclear envelope and the nucleouls have disappeared.
What happens in Metaphase?
Epithelial
What type of tissue has the greatest ability to regenerate?
Like a waterfall=down
The movement of water and solutes thru a membrane as a result of a pushing force that is greater on one side than the other side by hydrostatic pressure.
Describe filtration
Dialysis for the kidneys
What is an example of filtration?
Smooth=makes new cell membrane
Rough= transports newly made proteins made by ribosomes
What are two kinds of Endoplasmic Reticulum (ER)?
Endoplasmic Reticulum (ER)
What is a network of connecting sacs and canals that carry substances thru the cytoplasm from the nucleus?
Cell nucleus
What contains the genetic code instructions for making proteins which, in turn determine the cell structure and function?
DNA
What does the cell nucleus contain?
Cytoplasm
What lies between the plasma membrane and the nucleus and it is the "living matter"
Only in cells
Where does cytoplasm exist?
1) Keeps the cell intact (like skin)
2) gateway between the fluid inside the cell and the fluid around it. Certain fluids are allowed to move thru the membrane and others are not.
3) It communicates with receptors
What are 3 functions of the plasma membrane?
Each cell in the body is surrounded by a thin membrane call the plasma membrane (not part of the cell.
What is the plasma membrane?
Ribosomes
Endoplasmic reticulum (ER)
golgi apparatus
mitochondria
lysosomes
centroiles
cilia
flagella
List the 8 organs (organelles)?
Organelles
What group of small structures make up much of the cytoplasm?
Protein factories (make enzymes and proteins)
What are Ribosomes?
Tissue fluid not in the cell, it surrounds the cell.
What is interstitial fluid?
Connective tissue
What type of tissue is the most abundant and widely distributed in the body?
Little organs
What is another name for organelles?
Cardiac and smooth muscle tissue
What type of muscle is involuntary?
Tissues repairing themselves by allowing phagocytosis
What is regeneration of tissue?
Power plants of the cell
What is mitochondria?
Cellular respiration
What happens in the mitochondria?
Digestive bags, They eat microbes (ex lice)
What are lysosomes?
nucleus
What structure controls every organelle in the cytoplasm?
finger like projections of the plasma membrane (increase the curface are of a cell) for absorption.
Why are microvilli important?
nucleouolus
What dense region of nuclear material programs the formation of ribosomes in the nucleus?
Golgi apparatus
What are tiny, flattened sacs stacked on one another near the nucleus?
Diffusion of water across a permeable membrane but not solutes (already disolved in water)
What is osmosis?
Inherited condition from damage to the ion pump (chlorides) abnormally thick secretions in the airways and digestive system
What is cystic fibrosis?
The process by which substances scatter evenly themselves thru all the available space
What is diffusion?
Passive Transport *does not take energy
Diffusion is an example of what type of transport process?
Chemical processing and packaging center from the ER- flattened sacs stacked on one another near the nucleus.
What is the function of the golgi apparatus?
Adenosine triphosphate (ATP)
What chemical substance is required for active transport?
In the nucleus
Where are the chromosomes and chromatin located?
Active- required energy by the cell
Passive-doesnt require energy
What is the difference between active and passive transport?
Chromatin
What are the thread-like hereditary molecules in the nucleus called?
Forms tubules in the kidneys
What is simple cuboidal epithelium?
Transport and absorption
What are the functions of simple squamous epithelium?
Protection
What are the functions of stratified squamous epithelium?
Absorption
What are the functions of columnar epithelium?
Can be 10 layers found in areas that stretch such as the bladder or stomach.
Where do you find stratified transitional epithelium?
Each cell touches the basemen membrane, it lines the trachea
What is Pseudostratified Epithelium?
squamous= flat
cuboital= cube
columnar= column
transitional= relaxed or stretched
What are 4 manes of different Epithelial cells?
