Central and Peripheral Nervous System Mr Koh Learning Intentions 1) I should be able to identify the two components of the CNS 2) I should be able to identify the 4 lobes of the Brain and their functions 3) Understand the diff erence between aff erent and efferent meaning 4) Be able to list the two divisions of the PNS 5) Be able to list the two divisions of the parasympathetic ANS.  Do Now Draw the 3 types of neurons Name each of the 3 types neurons Briefly describe their function No iPad or referring to your notes for this activity Purpose of the N.S 1) Coordinate all activity of the body 2) Enables the body to respond and adapt to changes both inside and out  There are two types of N.S 1) Central Nervous System 2 Major Structures 1) Brain 2) Spinal Cord  4 lobes of the Brain 1) Frontal Lobe 2) Parietal Lobe 3) Temporal Lobe 4) Occipital Lobe 4 lobes of the brain 1) Frontal = Reasoning & Thought 2) Parietal => Integrating sensory information 3) Temporal => Auditory inform from ears 4) Occipital => Visual info from eyes Spinal Cord It is the link between the brain and the nerves Sensory neurons send nerve impulse to the spinal cord => travels up to the brain Afferent Efferent Peripheral Nervous System All the nerves that branch off from the brain & spine There are two divisions 1) Somatic 2) Autonomic Somatic Peripheral Nervous System Nerves that connect to skin, sensory organs and skeletal muscles All voluntary muscle movement Responsible for processing information from external stimuli Autonomic Peripheral Nervous System 2 divisions Sympathetic Parasympathetic  Activity Act ivity 4 : Ce nt ral and Pe rip h eral N ervous S ys t ems (FLOW CHA RT ) 1.
