Spinal nerves, cranial nerves and autonomic nervous system 1 of 45 What make up the components of the CNS? Brain and spinal cord 2 of 45 What is the ventral root of a nerve? motor, efferent fibres away from the CNS 3 of 45 What is the dorsal root of a nerve? sensory, afferent fibres toward the CNS 4 of 45 Name a sensory cranial nerve only optic 5 of 45 name a motor cranial nerve only hypoglossal 6 of 45 name a motor and sensory cranial nerve facial 7 of 45 is the autonomic nervous system part of the CNS or PNS? PNS 8 of 45 What is the sympathetic division of the autonomic nervous system for? fight or flight 9 of 45 what is the parasympathetic nervous system for? rest and digest 10 of 45 What are the gyri and sulci on the brain? gyri = bumps, sulci = folds 11 of 45 what does grey matter consist of? cortex, inner spinal cord and cell bodies 12 of 45 what does the white matter consist of? corpus callosum, outer part of spinal cord and axons 13 of 45 why are axons white? due to the presence of myelin 14 of 45 What is the frontal lobe specialised for? movement, judgement and behaviour 15 of 45 What is the parietal lobe specialised for? somatosensory perception and spatial attention 16 of 45 What is the temporal lobe specialised for? Object/face recognition, memory and emotion 17 of 45 What is the occipital lobe specialised for? visual processing only 18 of 45 what is the brainstem specialised for? unconscious movement 19 of 45 What is the cerebellum specialised for? balance, motor and eye movement 20 of 45 What is the hypothalamus specialised for? controls hunger and thirst (homeostasis) 21 of 45 What is the thalamus specialised for? directs sensory information to correct areas 22 of 45 What is the basal ganglia loop for? motor control and reward/value 23 of 45 What are the 3 meninges? dura mater, pia mater and arachnoid membrane 24 of 45 Why is arachnoid different to the other membranes? filled with cerebral spinal fluid 25 of 45 what are the 2 main functions of the ventricular system? acts as a shock absorber and provides exchange medium between blood and brain 26 of 45 What makes up the brain? Neurons and ... Glia 27 of 45 Neurons can communicate... electrically and chemically 28 of 45 What was Cajal's theory of neurons? All neurons are independent units 29 of 45 What was Cajal's theory called? Neuron Doctrine 30 of 45 What does the reticular theory state? all neurons link to each other by anastomosis 31 of 45 Who came up with the reticular theory? Golgi 32 of 45 what is the law of dynamic polarisation? Information flows in a predictable and consistent direction within each nerve cell 33 of 45 what is the principle of connectional specificity? There is no cytoplasmic continuity between nerve cells and these cells do not form random networks 34 of 45 what are 4 differences between axons and dendrites? many dendrites, smaller dendrites, dendrites dont have a hillock and dendrites have no myelin 35 of 45 what are functions of neurons? sensory, motor, relay and excitatory/inhibitory 36 of 45 what are the 3 shapes of neurons? multipolar, biopolar and unipolar 37 of 45 is the brain the same thickness everywhere? no 38 of 45 How many neuron to glial cells are there? 200:4 39 of 45 what is the function of schwann cells? provide myelin to the PNS 40 of 45 what is the function of oligodendrocytes? provide myelin to the CNS 41 of 45 what is the function of astrocytes? regulate adjacent capilaries +nourish 42 of 45 what is the function of microglia? break down debris forming after damage 43 of 45 What is multiple sclerosis? demylenation of CNS nerves 44 of 45 Why is Multiple sclerosis considered an autoimmune disease? immune system attacks myelin from oligodendrocytes 45 of 45
