Cards in this deck (20)
- 1Cell Body / SomaContains the nucleus;
metabolic centre
maintains homeostasis - 2AxonsSend information to other structures
- 3DendritesReceive information
Located around cell body - 4Axon TerminalsSend efferent information to other neurons
- 5Sensory / Afferent NeuronsSend info to the CNS
- 6Motor / Efferent NeuronsCarry information away from CNS to effectors
- 7InterneuronsWithin the CNS;
Work as connections between motor and sensory neurons - 8Glial CellsProvide nutrition and support for neurons
- 9Cerebral Cortex - Frontal Lobe FunctionVoluntary movement control.
Contains Supplemental Motor Area (SMA);
Premotor Cortex;
Primary Motor Cortex - 10Cerebral Cortex - Parietal Lobe FunctionPerception of sensory info.
Contains primary somatosensory cortex;
sensory association areas. - 11Cerebral Cortex - Occipital Lobe FunctionPerception of visual info
- 12Cerebral Cortex - Temporal Lobe FunctionAreas important for memory
- 13Function of the Sensory CortexReceive sensory and motor information;
Learning of movement; - 14Associations Areas FunctionsDistributed throughout cortex;
Associating and piecing together information from different areas. - 15Motor Areas FunctionsPlanning, preparation and execution of movements
- 16Basal GangliaSubcortical; Contains 4 neuclei;
Receives info fron cerebral cortex and brainstem;
Critical in scaling and modifying parameters of movement (velocity, amplitude and direction) - 17ThalamusGroup of nuclei in diencephalon.
Receives and integrates sensory information;
Filters and gates irrelevant information - 18Cerebellum / "Small Brain"Located below and behind cerebrum.
Coordinates and monitors movement, mainly error detection and correction. - 19Alpha Motor NeuronsInnervate skeletal muscle
- 20Motor UnitAlpha neuron and all muscle fibres it innervates
