To collect, process, and respond to our environment + To coordinate the workings of different organs and cells. 2 of 28 What is the PNS and the CNS? Peripheral Nervous System + Central Nervous System. 3 of 28 What two components make up the Central Nervous System? The Brain and the Spinal Cord. 4 of 28 What's the responsibility of the Central Nervous System? To control behaviour and physiological processes. 5 of 28 What's the cerebrum? The Brain. 6 of 28 What's the brain the center of? All conscious awareness. 7 of 28 What's the brains outer layer called? The cerebal cortex. 8 of 28 How many hemispheres does the brain have? Two. 9 of 28 What's the spinal cord responsible for? Reflex actions. 10 of 28 What are the names of the four lobes of the brain? Frontal, Temporal, Occipital, Parietal 11 of 28 What is the frontal lobe responsible for? High functioning orders, e.g. planning, reasoning, logic 12 of 28 What is the temporal lobe responsible for? Processing auditory information 13 of 28 What is the parietal lobe responsible for? Integrating information from the different senses 14 of 28 What is the occipital lobe responsible for? Processing visual information 15 of 28 What does the cerebellum control? Motor control/Movement 16 of 28 What does the brain stem control? Involuntary processes, e.g. breathing 17 of 28 What are the 3 parts of the brain stem? Midbrain, Pons, Medula 18 of 28 What is the responsibility of the Peripheral Nervous System? Transmitting messages via millions of neurons to and from the CNS. 19 of 28 What are the two sub divisions of the PNS? Autonomic Nervous System + Somatic Nervous System 20 of 28 What is the Somatic Nervous System responsible for? Carrying sensory and motor information to and from the CNS. 21 of 28 What is the Autonomic Nervous System responsible for? Controlling involuntary bodily functions. 22 of 28 What are the two sub divisions of the ANS? Sympathetic Nervous System + Parasympathetic Nervous System. 23 of 28 True or False: Are the SNS and PSNS antagonistic? True - they work in opposite pairs, e.g. one contracts, the other relaxes 24 of 28 What does the PSNS do? Calm, Restore, Digest. 25 of 28 What does the SNS do? Emergency Response, e.g. Fight or Flight. 26 of 28 What does the SNS do to the heart rate, blood pressure, and lungs? Increases heart rate, increases blood pressure, dilates bronchi. 27 of 28 What does the PSNS do to the heart rate, blood pressure, and lungs? Decreases heart rate, decreases blood pressure, constricts bronchi. 28 of 28
