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.

the structure and functions of sensory, relay and motor neurones

To include differences between the structure and function of myelinated and non-myelinated neurones.

the generation and transmission of nerve impulses in mammals

To include how the resting potential is established and maintained and how an action potential is generated (including reference to positive feedback) and transmitted in a myelinated neurone AND the significance of the frequency of impulse transmission.

the structure and roles of synapses in neurotransmission

To include the structure of a cholinergic synapse AND the action of neurotransmitters at the synapse and the importance of synapses in summation and control, including inhibitory and excitatory synapses.
