Please feel free to use this PowerPoint presentation in the classroom. It is intended to support the KS3 & KS4 curriculum and the Scottish S3-S4 curriculum. . KEY LEARNING: . Introduces students to a range of different neurotoxins, from . Following a stimulus, explain how the opening of sodium ion channels affects the potential difference across a neurone cell membrane. . Describe and explain the movement of sodium ions if the potential difference across a neurone cell membrane reaches the threshold level. . Ben . Allin. bsa04@ic.ac.uk. Cells of the nervous . system.

Node of Ranvier. Motor neurones transmit impulses from the central nervous system to effector (muscle or gland). . The myelin sheath is formed by . Schwann Cells . wrapping themselves around the axon along its length. The enclosing sheath is made of lipids and proteins. The sheath increases the speed of conduction of nerve impulses. .
