Coordination And Response
Akopọ
Touch something hot and your hand pulls away before you even feel the pain. That split-second response is your nervous system at work, sending electrical signals faster than you can think. It is the system that keeps all the parts of your body working together.
In this lesson you will learn how the nervous system is organised into a central and a peripheral part, meet the three kinds of neurone, and trace a reflex arc from stimulus to response. You will also discover how signals jump the gap between neurones at a junction called a synapse.
Awọn Afojusun
- State that electrical impulses travel along neurones
- Describe the mammalian nervous system in terms of: (a) the central nervous system (CNS) consisting of the brain and the spinal cord (b) the peripheral nervous system (PNS) consisting of the nerves outside of the brain and spinal cord
- Describe the role of the nervous system as coordination and regulation of body functions
- Identify in diagrams and images sensory, relay and motor neurones
- Describe a simple reflex arc in terms of: receptor, sensory neurone, relay neurone, motor neurone and effector
- Describe a reflex action as a means of automatically and rapidly integrating and coordinating stimuli with the responses of effectors (muscles and glands)
- Describe a synapse as a junction between two neurones
- [Supplement] Describe the structure of a synapse, including the presence of vesicles containing neurotransmitter molecules, the synaptic gap and receptor proteins
- [Supplement] Describe the events at a synapse as: (a) an impulse stimulates the release of neurotransmitter molecules from vesicles into the synaptic gap (b) t he neurotransmitter molecules diffuse across the gap (c) n eurotransmitter molecules bind with receptor proteins on the next neurone (d) an impulse is then stimulated in the next neurone
- [Supplement] State that synapses ensure that impulses travel in one direction only
