Ribosomes
A process in which a cell engulfs extracellular material through an inward folding of its
plasma membrane. Includes pinocytosis (taking in small amounts of fluid) and
Phagocytosis (used by macrophages and neutrophils) to engulf and destroy foreign
substances

Endocytosis
,a neural impulse; a brief electrical charge that travels down an axon. The resting
membrane is rapidly changed from negative to positive. Na+ flows in, K+ flows out.
Depolarization occurs. Then K+ flows back in and the cell is repolarized

Action potential
Cells use gylcolytic pathway in cytosol and make 2 molecules of ATP from 1 glucose

Aneraboic Pathway
Most common tissue. Supports/connects tissues. Its cells produce extracellular
matrix. Make up organ capsules. 1. connective tissue proper=loose (areolar), adipose,
dense. 2. connective tissue specialized (blood, bone, cartilage
Give this one a try later!
Connective tissue
Increase in cell size or tissue mass. Results from an increased workload on an organ
or body part and is commonly seen in cardiac and skeletal muscle tissue. Common
cause of left Vent. hypertrophy=hypertension.
