From the integration centre to the effector |
|
|
Name the two sub sections of the PNS |
Sensory and motor |
|
|
Name the 3 sub sections of the motor and their roles |
Entric - gut, somatic - skeletal musc (voluntary), autonomic - smooth musc (involuntary ) |
|
|
Name the two subsections of the autonomic NS and their catch phrase |

|
Name the 6 major areas of the brain |

|
|
Name the 7 main parts of a neurone |
Dendrites, soma, nucleus, axon, Myelin, node of Ranvier and axon terminals |
|
|
Name the 4 (5) stages of action potential w deets |
Resting - Na / k closed (-70 ) Depolarisation - Na opens and enters cell if it reaches (-55) it will trigger action potential RePolarisation - Na closes. K opens and flows out of cell (more neg) Hyperpolerisation - K continues to outflow below -70 Return to rest |
|
|
Name the two types of synapses |
Electrical and chemical |
|
|
What is the chemical synapse process |
Ca into cell Ca signals vessicals to dock Once vessicals have docked they release neurotransmitters via exocytosis Neurotransmitters diffuse and bind to receptors |
|
|
Electrical synapse process |
Gap junction connects two cells and lets direct message flow via electrical currents |
|
|
Name the 5 types of receptors and their purpose |
Mechanoreceptors - mechanical stimuli (stretching, bending ect) Thermoreceptors - temp Noicereceptors - pain Photoreceptors- light Chemoreceptors - chemicals |
