This lesson describes how communication occurs between cells by cell signalling. The PowerPoint and accompanying resource have been designed to cover point 5.1.1 (b) of the OCR A-level Biology A specification and focuses on the use of the nervous system for communication between the CNS and effectors and the release of hormones to bring about responses.
As this is one of the first lessons to be delivered in module 5, this lesson has been specifically planned to prepare students for the upcoming topics of neuronal and hormonal communication. Students begin by learning that cell signalling governs the basic activities of cells and coordinates multiple cell actions. Moving forwards, the next part of the lesson focuses on the nervous system and students will learn that an electrical impulse will be conducted on a somatic or an autonomic motor neurone depending upon the type of muscle to be stimulated. This provides some introductory information for modules 5.1.3 and 5.1.5. The remainder of the lesson describes how the hormones that are secreted by the cells of endocrine glands allow communication with target cells and the different actions of peptide and steroid hormones is considered.

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

Module 5.1.1: Communication and homeostasis (OCR A-level Biology A)
This bundle of 4 lessons covers the content of module 5.1.1 of the OCR A-level Biology A specification, titled communication and homeostasis. As this module tends to be one of the first to be taught in the second year of the course, it's extremely important that links are made to upcoming topics as well as challenging the students on their prior knowledge of modules 2 - 4. This is achieved through a wide range of tasks, that include exam-style questions, differentiated tasks and guided discussion periods. Quick quiz competitions are also used to introduce key terms and values in a fun and memorable way. The following specification points are covered by the 4 lesson PowerPoints and accompanying resources included in this bundle: * The communication between cells by cell signalling * The principles of homeostasis * The differences between negative and positive feedback * The physiological and behavioural responses involved in temperature control in endotherms and ectotherms As detailed above, these lessons have been specifically planned to tie in with the other parts of module 5, including neuronal communication, hormonal communication and animal and plant responses. If you would like to sample the quality of the lessons in this bundle, then download the principles of homeostasis and temperature control in ectotherms lessons as these have been uploaded for free

Really informative for a topic which is small on the syllabus but growing I importance due to the number of questions asked in recent exam seasons.
