Receptors + Reflex Arc Yr 10 – Human Biology 101 Do Now Activity + Draw a flow diagram of what we did in the last class. Ensure to include the following words + Central – Peripheral + Afferent – Efferent + Autonomic – Somatic + Sympathetic – Parasympathetic + Sensory - Motor  Learning Intention Success Criteria The reflex arc comprises I can be able to define what of specially structured a reflex and reflex arc is neurons, including Give 2 examples of a reflex sensory, interneuron and Identify and explain in a motor neurons, to flow diagram, the 5 transmit information from components of a reflex arc the receptor to the Understand the different effector to respond rapidly to stimuli types of sense receptors What are the different types of sense receptors? 1. Thermoreceptors (respond to changes in temperature) 2. Photoreceptors (reacts to light) 3. Chemoreceptors (responds to chemicals) 4. Mechanoreceptors (responds to pressure, touch and vibration) 5. Nociceptors (respond to indicate pain) These receptors will each connect to a sensory neuron and transmit that message towards the CNS. What is a reflex What is a reflex arc + Involuntary reaction in + A neural pathway that response to a controls a reflex action potentially damaging + Does not concern the brain stimulus by activating muscles or glands. + Purpose: Minimise damage to the body from potentially harmful conditions 5 components of a reflex arc + 1) Receptor + 2) Sensory Neuron / Afferent Neuron + 3) CNS (Spinal Cord) => Interneuron + 4) Motor Neuron + 5) Effector Scenario + A person holds an extra hot mug of coffee that was too hot to the touch. The person quickly takes her hand away as a reflex. Outline a nervous system flow diagram in response to this scenario. Complete the worksheets Early Finishers – Extra worksheets
