cell bodies of visceral afferent fibers
dorsal root ganglia
fluid selectively permeable barrier consisting of ampipathic phospholipid bilayer contains integral proteins and peripheal proteins
Plasma membranes
site of cell synthesizing activity
cytoplasm
cytoplasmic inclusions; glycogen, pigment granules, secretory granules, lipid droplet
cytoplasmic inclusions
cytoplasm
cytoplasmic matrix with ground substance
RER
protein synthesis for export outside cell
studded with ribosomes
SER
steroid syntesis(adrenal cotex and testes)
sequesters Ca2+(skeletal and cardiac muscle)
lipid and glycogen metabolism(liver)
golgi app
posttrans. modification and package of proteins
lysosome production
(addds oligosacch. for glycoproteins and sulfate groups for proteoglycans)
ATP production via kreb cycle and ox phos
mitochondrion
inner and outer membrane
contain own cyclic DNA and not present in erythrocyte
Mitochondria
lysosome
hydroltic enzymes digest microorganism
produced by Golgi App
elimination of H2O2 by various ox enzymes
peroxisomes
vesicles formed as result of phagocytosis
endosome
provide structure support
intracell transport
cell movement
made of tubulin
microtubules
axonemes
specialized group of microtubule found in cilia and flagella arranged in “9+2 “ pattern
centriole
provide microtubule organization
form ends of mitoti spindleduring mitosis
important for muscle contraction and provide cellular movement or anchorage
microfilament
provide cytoskeletal support
int. filament

repressed X chromosome found in cells in females
appears as dense chromatin mass adjacent to nuc membrane
used for sex IDing
fingerlike structures of various lengths on apical surface of most ep cells

long microvilli located only in epididymis and sensory cels of inner ear
cilia
short hairlike structures used for locomotion or movement of substances along cell membrane
function in synchronous coordinated wave motion
require basal bodies for development

function in undulating snake like movement
in humans found in spermatozoa
