This is a highly detailed and engaging lesson that covers the detail of specification point 5.1.1 © of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the generation and transmission of nerve impulses in mammals. This topic is commonly assessed in the terminal exams so a lot of time has been taken to design this resource to include a wide range of activities that motivate the students whilst ensuring that the content is covered in the depth of detail that will allow them to have a real understanding. Interspersed within the activities are understanding checks and prior knowledge checks to enable the students to not only assess their progress against the current topic but also to challenge themselves on the links to earlier topics such as methods of movements across cell membranes and saltatory conduction. There are also a number of quiz competitions which are used to introduce key terms and values in a fun and memorable way and discussion points to encourage the students to consider why a particular process or mechanism occurs.
Over the course of the lesson, the students will learn and discover how the movement of ions across the membrane causes the membrane potential to change. They will see how the resting potential is maintained through the use of the sodium/potassium pump and potassium ion leakage. There is a real focus on depolarisation to allow students to understand how generator potentials can combine and if the resulting depolarisation then exceeds the threshold potential, a full depolarisation will occur. At this point in the lesson students will discover how the all or nothing response explains that action potentials have the same magnitude and that instead a stronger stimulus is linked to an increase in the frequency of the transmission. The rest of the lesson challenges the students to apply their knowledge to explain how repolarisation and hyperpolarisation result and to suggest advantages of the refractory period for nerve cells.
This lesson has been designed for students studying the OCR A-level Biology course and ties in nicely with other uploaded lessons on mammalian sensory receptors and the structures and functions of the neurones.

Homeostasis, Excretion, Neuronal and Hormonal communication (OCR A-level Biology A)
This bundle of 20 lessons covers the majority of the content that's included in modules 5.1.1 - 5.1.4 of the OCR A-level Biology A specification. All of the lessons are highly detailed and have been planned at length to ensure that they are filled with a wide range of tasks to engage and motivate the students whilst checking on their understanding. The following specification points are covered by the lessons in this bundle: 5.1.1: Communication and homeostasis * The communication between cells by cell signalling * The principle of homeostasis * The physiological and behavioural responses involved in temperature control in endotherms and ectotherms 5.1.2: Excretion as an example of homeostatic control * The functions of the mammalian liver * The gross structure and histology of the kidney * The processes of ultrafiltration and selective reabsorption * The control of the water potential of the blood * The effects of kidney failure and its potential treatments 5.1.3: Neuronal communication * The roles of mammalian sensory receptors in converting stimuli into nerve impulses * The structure and functions of sensory, relay and motor neurones * The generation and transmission of nerve impulses in mammals * The structures and roles of synapses in transmission 5.1.4: Hormonal communication * Endocrine communication by hormones * The structure and functions of the adrenal glands * The structure of the pancreas * The regulation of blood glucose concentration * The difference between diabetes mellitus type I and II * The potential treatments for diabetes mellitus It is estimated that it will take in excess of 2 months of allocated A-level teaching time to cover the detail included in these lessons If you would like to sample the quality of the lessons in this bundle, then download the following lessons as they have been shared for free: * The principles of homeostasis * Temperature control in ectotherms * The functions of the liver * The structure of the kidney * The generation and transmission of nerve impulses * Endocrine communication

Neuronal & hormonal communication (OCR A-level Biology)
This lesson bundle contains 10 lesson PowerPoints, which are highly detailed, and along with their accompanying resources have been designed to cover the content of modules 5.1.3 & 5.1.4 of the OCR A-level Biology A specification, titled neuronal communication and hormonal communication. Each lesson contains a wide range of tasks, that include exam-style questions with mark schemes written into the PowerPoint that students can use to assess their understanding of the current topic as well as previously covered topics. There are also differentiated tasks, discussion points and quick quiz competitions to introduce key values and terms in a fun and memorable way. This lesson bundle covers the following specification points in modules 5.1.3 & 5.1.4: * The roles of mammalian sensory receptors in converting different types of stimuli into nerve impulses * The structure and functions of sensory, motor and relay neurones * The generation and transmission of nerve impulses in mammals * The structure and roles of synapses in neurotransmission * Endocrine communication by hormones * The structure and functions of the adrenal glands * The histology of the pancreas * The regulation of blood glucose concentration * The differences between diabetes mellitus type I and II * The potential treatments for diabetes mellitus If you would like to sample the quality of the lessons in this bundle, then download the nerve impulse and endocrine communication lessons as these have been uploaded for free.
