This fully-resourced lesson covers the content of the first part of specification point 5.1.3 (d) of the OCR A-level Biology A specification that states that students should be able to demonstrate and apply an understanding of the structures and roles of synapses in nervous transmission. The majority of the lesson uses the cholinergic synapse as the example but other neurotransmitters are considered to provide the students with a wider view of this topic.
The lesson begins by using a version of the WALL (as shown in the cover image) which asks the students to group 12 words into three groups of 4. Not only will this challenge their prior knowledge from topics earlier in this module but it will also lead to the discovery of four of the structures that are found in a synapse. Moving forwards, students are introduced to aectylcholine as the neurotransmitter involved at cholinergic synapses and they will start to add labels to the structures found in the pre-synaptic bulb. Time is taken to focus on certain structures such as the voltage gated channels as these types of channel were met previously when looking at the depolarisation of a neurone. There is plenty of challenge and discovery as students are pushed to explain why organelles like mitochondria would be found in large numbers in the bulb. With this process being a cascade of events, a bullet point format is used to ensure that the key content is taken in by the students and again key points like exocytosis and the action of acetylcholinesterase are discussed further. The final part of the lesson challenges the application aspect of the specification as students are introduced to unfamiliar situations in terms of synapses with new drugs like MDMA and are asked to work out and explain how these affect the nervous transmission.
Understanding checks and prior knowledge checks are included throughout the lesson so that students can not only assess their progress against the current topic but also see whether they can make links to earlier topics.
This lesson has been designed for students studying the OCR A-level Biology A course but could be used with very able GCSE students who are keen to develop their understanding of synapses over and above the small detail that is provided at that level. This lesson also ties in nicely with the other uploaded lessons from module 5.1.3 (neuronal communication) which are sensory receptors, neurones, nerve impulses and summation.

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.

Module 5.1.3: Neuronal communication (OCR A-level Biology A)
All of the lessons that are included in this bundle have been designed to ensure that all of the content in module 5.1.3 (neuronal communication) of the OCR A-level Biology A specification is covered. The wide range of activities and differentiated resources will motivate the students whilst the regular understanding and prior knowledge checks will allow them to assess their progress against the current topic as well as challenging them to make links to earlier topics. All of the specification points in module 5.1.3 have been covered by the following lessons: (a) The roles of mammalian sensory receptors (b) Sensory, relay and motor neurones and saltatory conduction (c)The generation and transmission of nerve impulses (d) The structure of cholinergic synapses (d) The role of synapses in summation and control
