Humoral vs. Cell-mediated

Humoral immunity

Antibody specificity – epitopes

Ectotherm

Temperature control

Osmoregulation

Action potential Depolarize – inside of

axon more positive

Hyperpolarize – inside of axon less negative

Refractory period – “recovery” period to reestablish resting potential

Synapse - neurotransmitters
