|
Hyaloplasm |
Basic structureless cytoplasm |
|
|
Cell inclusions or 'paraplasm' includes: |
secretory granules, glycogen, lipid droplets, crystaloids, pigments |
|
|
Contains genetic information of the cell; most conspicuous organelle |
Nucleus (Chromatin is BASOPHILIC) |
|
|
There are two types of chromatin (BASOPHILIC): |
Heterochromatic (inactive) and Euchromatin (active) |
|
|
allows for the passage of RNA, proteins into the cytoplasm |
Nuclear pores |
|
|
produces rRNA |
Nucleolus |
|
|
Connects to the R.E.R |
nuclear envelope |
|
|
4 most euchromatic cell types: |
Neurons, Hepatoycytes, pancreatic acinar cells, sertoli cells |
|
|
the mitochondria have little opportunity for genetic recombination between different lineages because: |
uniparental inheritance |
|
|
The mitochondria is a double membrane enclosed organelle with: |
cristae |
|
|
The mitochondria are involved with initiation of apoptosis by releasing: |
cytochrome C |
|
|
3 functions of the smooth endoplasmic reticulum: |
lipid biosynthesis, detoxification, sequestration of calcium ions |
|
|
4 functions of the rough endoplasmic reticulum: |
segregate proteins not destined to the cytoplasm, glycosylation of glycoproteins, synthesis of phospholipids, assembly of multichain proteins |
|
|
Modifies and packages proteins, best developed in secretory cells |
golgi body- requires special stain to see |
|
|
3 functions of lysosomes: |
phagocytosis, pinocytosis and intracellular digestion (contains hydrolytic enzymes) |
|
|
Small enzymatic complexes for intracellular digestion that require ubiquitin; primary function is recycling amino acids from endogenous proteins |
Proteasomes |
|
|
small globular protein present in ALL eukaryotic cells |
Ubiquitin |
|
|
contain the enzyme catalase which can degrade intracellular hydrogen peroxide; can degrade toxic molecules and some prescription drugs |
Peroxisomes |
|
|
Cytoskeleton is made up of: 3 |
microfilaments (actin & myosin), intermediate filaments (keratin), microtubules |
|
|
Detection of intermediate filaments help with: |
the identification of cancer cells |
|
|
INCLUSIONS include: 3 |
pigments, glycogen, lipid droplets |
|
|
Glycogen inclusions are found in what 3 cell types |
muscle, liver and neurons |
|
|
4 pigment inclusions |
melanin (black), lipofuscin (brown), lutein (yellow), hemosiderin |
|
|
Self-repicating organelle; double membrane with cristae; not visible under LM in ordinary staining |
MITOCHONDRIA |
|
|
3 endogenous pigments |
melanin; hemosiderin; lipofuscin |
|
|
3 types of intercellular junctions: |
tight, anchoring and communicating |
