Description
| Question | Answer |
| Cell Body / Soma | Contains the nucleus; metabolic centre maintains homeostasis |
| Axons | Send information to other structures |
| Dendrites | Receive information Located around cell body |
| Axon Terminals | Send efferent information to other neurons |
| Sensory / Afferent Neurons | Send info to the CNS |
| Motor / Efferent Neurons | Carry information away from CNS to effectors |
| Interneurons | Within the CNS; Work as connections between motor and sensory neurons |
| Glial Cells | Provide nutrition and support for neurons |
| Cerebral Cortex - Frontal Lobe Function | Voluntary movement control. Contains Supplemental Motor Area (SMA); Premotor Cortex; Primary Motor Cortex |
| Cerebral Cortex - Parietal Lobe Function | Perception of sensory info. Contains primary somatosensory cortex; sensory association areas. |
| Cerebral Cortex - Occipital Lobe Function | Perception of visual info |
| Cerebral Cortex - Temporal Lobe Function | Areas important for memory |
| Function of the Sensory Cortex | Receive sensory and motor information; Learning of movement; |
| Associations Areas Functions | Distributed throughout cortex; Associating and piecing together information from different areas. |
| Motor Areas Functions | Planning, preparation and execution of movements |
| Basal Ganglia | Subcortical; Contains 4 neuclei; Receives info fron cerebral cortex and brainstem; Critical in scaling and modifying parameters of movement (velocity, amplitude and direction) |
| Thalamus | Group of nuclei in diencephalon. Receives and integrates sensory information; Filters and gates irrelevant information |
| Cerebellum / "Small Brain" | Located below and behind cerebrum. Coordinates and monitors movement, mainly error detection and correction. |
| Alpha Motor Neurons | Innervate skeletal muscle |
| Motor Unit | Alpha neuron and all muscle fibres it innervates |
