Anatomy Week2

Cytoskeleton
- Interconnected network of fibers inside the cell
- Determines cell shape
- Organization and transport within the cell
Centrioles

Bundle of microtubules-direct movement of chromosomes during cell division
Microvilli

finger like extension of cell membrane
Cilia
- short hair like structure
- Movement of material
Flagellum
- long extensions
- propels sperm
Membranous Organelles

seperate reactions within time and the space
mitochondria
- double membrane structure
- synthesize most atp during cellular respiration
- "powerhouses of cell"
Golgi Apparatus
- Packaging center of the cell
- Secretory, transport, storage vesicles
lysosome
- contains digestive enzymes
- lysosomal storage-not active & accumulates
- tay sachs-inability to break glycolipids
peroxisome
- smaller than ribosomes
- endagarates fatty acids & toxins
Smooth ER

Synthesize fat & steroid
Rough ER

Putting modifications in proteins
Nucleoli
- Subunits of ribosomes are manufactured
- Synthesizes rRna
Chromosomes

DNA & associated proteins
Nucleoplasm

Semifluid inside nucleus
Filtration
- passage of solute through membrane or filter
- kidney
active transport

movement of particles against a concentration gradient
