| Repolarization | is a stage of an action potential in which the cell experiences a decrease of voltage due to the efflux of potassium (K+) ions along its electrochemical gradient. |
| acetylcholine (ACh) | neurotransmitter that binds at a motor end-plate to trigger depolarisation. |
| actin | protein that makes up most of the thin myofilaments in a sarcomere muscle fibre. |
| action potential | change in voltage of a cell membrane in response to a stimulus that results in transmission of an electrical signal; unique to neurons and muscle fibres. |
| cartilage | semi-rigid connective tissue found on the skeleton in areas where flexibility and smooth surfaces support movement. |
| central nervous system (CNS) | anatomical division of the nervous system located within the cranial and vertebral cavities, namely the brain and spinal cord. |
