Describes the apparent "jumping" of APs from one node to the next in myelinated neurons

Explains the relationship between conduction velocity and refractory periods

Describes the faster CV in myelinated neurons

Is the single most important factor causing the refractory period

Explains the relationship between axon diameter and conduction velocity

Most water is intracellular and next most is in the plasma.

Most water is extracellular and the next most is intracellular.

Most water is interstitial fluid and the least is in minor fluid compartments like the CSF and the eye

RER is involved in production of proteins and SER in production of ATP

RER is involved with protein synthesis and SER with the production of products for secretion from the cell

RER is linked to the nucleus and the Golgi apparatus and the SER is not.

RER is spotted with ribosomes and SER is smooth because of the absence of ribosomes.

RER uses enzymes for breakdown of waste material and SER uses enzymes and O2

To make the cell membrane more rigid by reducing phospholipid movement

To make the cell membrane more fluid, like olive oil

To organise phospholipids so that their hydrophilic head face the aqueous outside and the hydrophobic tails face inwards

To form kinks in the unstaurated hydrocarbon chains of the lipid bilayer

To increase the number of double bonds in the fatty acid chains of phospholipids

The set of membrane folds in mitochondria that make ATP

The way cells are organised to form the skeleton of the body

The intricate network of stacks of the Golgi apparatus

The intricate network of protein filaments that give the cell a well defined structure

The intricate inner fold of the mitochondrion where O₂ is used to produce ATP

The intermediate filaments made of keratins, laminin and neurofilaments.

The rough and smooth endoplasmic reticulum and the peroxisomes

The endoplasmic reticulum, the peroxisomes and the mitochondria

The microtubulues made of tubulin

The microfilaments made of actin and associated proteins
