| miniature end plate potential | <physiology> Small fluctuations (typically 0.5 mV) in the resting potential of postsynaptic cells. They are the same shape as, but much smaller than, the end plate potentials caused by stimulation of the presynaptic cell. Miniature end plate potentials are considered as evidence for the quantal release of neurotransmitters at chemical synapses, a single miniature end plate potential resulting from the release of the contents of a single synaptic vesicle. (12 Jan 1998) |

| water potential | <plant biology> The chemical potential (i.e. Free energy per mole) of water in plants. Water moves within plants from regions of high water potential to regions of lower water potential, i.e. Down gradient. (18 Nov 1997) |
| congenital giant pigmented nevus | These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (27 Sep 1997) |
| myogenic potential | Action potential of muscle. (05 Mar 2000) |
| postsynaptic potential | In a synapse, a change in the resting potential of a postsynaptic cell following stimulation of the presynaptic cell. For example: in a cholinergic synapse, the release of acetylcholine from the presynaptic cell causes channels to open in the postsynaptic cell. Each channel opening causes a small depolarisation, known as a miniature end plate potential (mepp), these sum to produce an excitatory postsynaptic potential. (18 Nov 1997) |
| potential | Existing and ready for action but not yet active. (18 Nov 1997) |
| potential energy | <chemistry> Energy due to position, it is stored energy which can be used to do work. (09 Jan 1998) |
| site potential tree | A tree that has attained the average maximum height possible given site conditions where it occurs. (05 Dec 1998) |
| somatosensory evoked potential | The computer-averaged cortical and subcortical responses to repetitive stimulation of peripheral nerve sensory fibres. (05 Mar 2000) |
| spike potential | The main wave in the action potential of a nerve; it is followed by negative and positive afterpotentials. (05 Mar 2000) |
| S potential | Prolonged, slow, depolarising or hyperpolarising responses to illumination; initiated between the photoreceptor and ganglion cell layers of the retina. (05 Mar 2000) |
| squid giant axon | <physiology> Large axons, up to 1mm in diameter, that innervate the mantle of the squid. Because of their large size, many of the pioneering investigations of the mechanisms underlying resting and action potentials in excitable cells were done on these fibres. (10 Mar 1998) |
| Nernst potential | See: Nernst equation and ion selective electrodes. (18 Nov 1997) |
| subependymal giant cell astrocytoma | <tumour> A rare astrocytoma, frequently located in the wall of the lateral ventricle, comprised of large glial cells with abundant eosinophilic cytoplasm and intermixed elongated astrocytes, associated with tuberous sclerosis. (05 Mar 2000) |
| surface potential | <cell biology, physiology> The electrostatic potential due to surface charged groups and adsorbed ions at a surface. It is usually measured as the zeta potential at the Helmholtz slipping plane outside the surface. (19 Jan 1998) |
