Nerve Impulses. Resting Potentials Electrical potential across plasma membrane of a cell Not conducting impulse.
Neurones & the Action Potential Neurones conduct impulses from one part of the body to another.
Outline Neuronal excitability Nature of neuronal electrical signals Convey information over distances Convey information to other cells via synapses Signals.
Passage of an action potential Aim: To understand how nerve impulses are propagated along a neurone.
Neuromuscular Adaptations to Conditioning Chapter 2.
Chapter 4 The Action Potential. Nernst Relation [ion] out [ion] in E = mV log 10.
Topic Nerves Overview of the Nervous System Three major functions: Sensory input – sensory receptors receive signal – peripheral nervous.
AIM: How does the Nervous System work and how does it help the body maintain homeostasis? DO NOW: What is the function of the nervous system? What are.
