NEW OCR Biology A 5.3.2. Structure and Function of Neurones

This lesson begins with a fun, recap crossword on 5.3.1 (sensory receptors and generating nerve impulses) to test what students can remember from last lesson.

There is a detailed presentation explaining the structure and function of each type of neurone (sensory, relay and motor), accompanied with diagrams that students can annotate. This power point also describes the difference between myelinated and unmyelinated neurones, the structure of the myelin sheath and schwann cells, and the effect that this has on speed of conduction.

There is also a series of practice exam questions for students to apply the knowledge they have gained from the presentation, and a plenary word fill activity.

(a) to understand the roles of mammalian sensory receptors in
converting different types of stimuli into nerve
impulses to include an outline of the roles of sensory
receptors (e.g. Pacinian corpuscle) in responding
to specific types of stimuli and their roles as
transducers.
(b) to know the structure and functions of sensory, relay and
motor neurones and the differences between the structure
and function of myelinated and non-myelinated
neurones.
