chapter 3 a&p
the presence of chondrocytes indicates that a tissue is
cartilage
the structural & functional unit of all the living things is the
cell
cellular material located outside the nucleus yet inside the plasma membrane is the
cytoplasm
the nucleoplasm & cytosol make up the ____ fluid
intracellular
what is the significance of granulation tissue?
it formed during tissue repair
structural components of the nucleus
nuclear pores, nucleolus, chromatin, nuclear envelope
responsible for making the majority of ATP in a cell is the mitochondrion
organelle
the specialized cellular compartments within the cytosol of the cell are collectively called
organelles
part of plasma membrane & is hydrophobic
phospholipid "tails"
is the main component of the cell membrane
phospholipids
muscle tissue has no visible striations & has spindle-shaped cells
smooth
the type of muscle found in the walls of hollows organs, such as the stomach, and in the walls of blood vessels
smooth muscle
which tissue performs peristaisis to move substances, such as food, through the hollow organs of the body?
smooth muscle tissue
many layers of flattened cells should be termed (squamous)
stratified epithelial tissue
groups of the cells that a similar in both structure & function are known as
tissues
allows ions to pass directly from the cytoplasm of one cell to the cytoplasm of the adjacent cell
Gap junctions
nutrients & ions can pass directly from cell to cell through special membrane junctions known as
Gap junctions
final processing of proteins "tagged" for secretion occurs in which cellular organelle
Golgi apparatus
is responsible for forming secretory vesicles
Golgi apparatus
tissue is commonly called fat
adipose
the type of tissue consisting of cells embedded in an extracellular matrix is _____ tissue
connective
is a large amount of extracellular material (a characteristic)
connective tissue
the _____ is a network of proteins that forms an internal framework for the cell
cytoskeleton
the three major components of the cytoplasm are the
cytosol, organelles, inclusions
glands, such as the thyroid, that secrete their products directly into the blood rather than through ducts are classified as
endocrine
is a typed of tissue that has cells that are tightly packed, sit on a basement membrane, is avascular, & is easily regenerated?
epithelium
looking into a microscope, you notice cells swimming, propelled by along tail. what cell structure must these cells have in order to be mobile?
flagella
major functions in the cell membrane
forming channels-acting as receptors, anchoring cells to other structures
in the DNA within the cells nucleus in a typical eukaryotic cell you would expect to find
genes
the phospholipid tails are __________ ; which make the plasma membrane impermeable to water.
hydrophobic
acts as the digestive system of the cell breaking down materials
lysosome
tissue conducts electrochemical impulses
nervous
neurons & neuroglia are components of
nervous tissue
the cell type found in nervous tissue is the
neuron
part of the cell membrane is usually in contact w/ the interstitial fluid
phosphate heads of phospholipids
damaged tissues that are repaired by the same kind of cells experience a replacement process known as
regeneration
are organelles & they are located within one of the major components of the cell
ribosomes
is a characteristic of the cell membrane bc something's can easily pass through it while others cannot
semipermeable
a tissue constructed of a single layer of flattened cell is known as
simple squamous epithelium
what tissue is specialized for the rapid diffusion of gases and nutrients across its cells?
simple squamous epithelium
prevents substances from passing between adjacent cells
tight junctions
the membrane connections that prevents the leaking of fluid between cells are called
tight junctions
