Voltage-gated potassium (Kv) channels regulate the flow of potassium ions across the cell membrane of nerves and muscles. Proper functioning of these and other voltage-gated ion channels is critical for an animal to sense the environment and respond quickly to stimuli. Dysfunctional Kv channels,...

Tompkins MacDonald, Gabrielle Jean
Sponges are filter feeders that lack nerves and muscle but are nonetheless able to respond to changes in the ambient environment to control their feeding current. Cellular sponges undergo coordinated contractions that effectively expel debris. Syncytial sponges propagate action potentials through...
