|
Cilia
|
locomotor structure similar to flagella but smaller and more numerous. Function in motility, feeding and filtering
|
|
|
Flagella
|
locomotor structure that consists of a long, sheathed cylinder containing microtubules in a 9+2 arrangement. Function in motility
|
|
|
Glycocalyx
|
the outermost boundary that comes into direct contact with environment. Functions in adherence, protection and signal reception
|
|
|
Cell Wall
|
Beneath the glycocalyx and provides structural support & shape
|
|
|
Cell Membrane
|
a biayer of phospholipids and proteins specializing as selectively permeable barriers in transport
|
|
|
cytoplasmic matrix
|
provides the complex environment required for many cellular activities. Contains the cytoskeleton
|
|
|
Microfilaments
|
Scattered or organized into networks and arrays and play a major role in cell motion and cell shape changes
|
|
|
Microtubules
|
hollow cylinders that help maintain cell shape and are involved in cellular cellular movement, intracellular transport of substances and participate in organelle movement. Also form mitotic spindle and are found in flagella and cilia
|
|
|
Intermediate filaments
|
major components of the cytoskeleton that helps maintain cell shape and cellular movement
|
|
|
cytoskeleton
|
an intricate network of interconnected filaments that helps maintain cell shape and cellular movement
|
|
|
Nuclei
|
membrane-bound structures that house most of the genetic material of the cell
|
|
|
Chromatin
|
dense fibrous material seen within the nucleoplasm of the nucleus. Also the DNA containing part of the nucleus
|
|
|
chromosomes
|
long linear DNA molecules bound to histone proteins
|
|
|
nucleolus
|
region in the nucleus that is the site rRNA synthesis and a collection area for ribosomal subunits
|
|
|
nuclear envelope
|
a double membrane structure penetrated by nuclear pores that allow materials to be transported into or out of the nucleus
|
|
|
Hyponatremia
Causes? |
H2O retention (hemodilution or dilutional hyponatremia) common, loss of Na+ through skin, GI tract, kidneys, low intake
deficits of Na+ cause plasma hypoosmolality adn cellular swelling |
