Edexcel Igcse Biology Section B6 Pdf Nervous System Nerve The document outlines resources and learning objectives for a section on coordination for an edexcel igcse biology course. it includes specifications on understanding stimulus and response, the central nervous system, reflex arcs, and the eye. Study the human nervous system for igcse biology, including details on the central and peripheral nervous systems and neurone types with labelled diagrams.
Igcse The Nervous System 2.83 describe how responses can be controlled by nervous or by hormonal communication and understand the differences between the two systems. 2.84 understand that the central nervous system consists of the brain and spinal cord and is linked to sense organs by nerves. When exposed to a stimulus they generate an electrical impulse which passes along peripheral nerves to the cns, triggering a response. peripheral nerves contain sensory and motor neurones (nerve cells). (total for question = 3 marks) motor neurones are found in the nervous system. figure 16 shows a motor neurone.

This comprehensive igcse biology presentation explains the nervous system, focusing on how the body coordinates and responds to stimuli. learn about the central and peripheral nervous systems, reflex actions, neurons, synapses, and the role of neurotransmitters. Information is sent through the nervous system as electrical impulses – these are electrical signals that pass along nerve cells known as neurones a bundle of neurones is known as a nerve. In this lesson we will first study how the electrical impulses are carried along nerves, then the structure and mode of operation of the cns, and finally the eye and ear as two important receptors. Igcse biology section 2 lesson 8 * the conscious action 1. receptors in your foot detect a stone in your shoe 2. an impulse is sent along a sensory neurone 3. in the spinal cord another sensory neurone takes the impulse to the brain 4. the brain co oordinates the input and output 4 the conscious action 1.
