Anatomy Lec 3 Flashcards
3 Human cells in body
- Plasma membrane, cytoplasm & nucleus
Integral protein
◽️ both hydrophophilic & hydrophobic
◽️ Transport protein
Peripheral proteins
◽️Cell membrane support
◽️ support cell shape
Tight junctions
Keep cell together
-found in epithelial line
Desmosome
Button; zipper like
🔺Glue together & connect cells ; reduce tear
Gap Junction
Connect to connexon
🔻 Send signal to cells
Function of cell adhesion molecules (CAM)
Cells move across each other ; attract WBC to fight infections
Contact signal
Cells close together
Chemical signal
Interact w/ receptors & liagands ( change cell activity)
Mitochondria contain its own
🔶DNA, RNA & Ribosomes
🔶Use ATP
✖️Have fold call Cristae
Rough ER
🟠 sent Golgi for process
🟠 Protein secrets from cells
Smooth ER
🟣 Detox chemical ex: liver
Function of lysosome
-Garbage collector
- enzymes breaking down substance
Centrosome located
Near nucleus “ Cell Center”
Centrioles
From cilia & flagella
What’s in interphase
G0, G1, S phase , & G2
G1
Cell grows
S phase
DNA Replicate
G2
Cell prepare to ➗
Plasma membrane made of
Lipids
Glycocalyx determines
What belongs (self vs non-self)
Membrane receptors binding site for
Chemical signal
Gylcocalyx always involve
Cell adhension molecules & plasma membrane receptor
Ribosome made
Protein & RNA
Cells arise from
Pre existing cells
Smooth ER
Makes lipids & involve in detox
Golgi apparatus
Sort packages for delivery
Rough ER HAS
-Ribosome that make protein
-process through Golgi apparatus
