What structures input into the alpha motorneuron?
These either input directly or indirectly (via interneurons)
- Cerebral cortex
- Basal Ganglia
- Brainstem Nuclei
- Cerebellum
- Spinal motor neurons
Explain the differences in these pathways
- Note:
- crossing over
- location of pathway
- don’t need to know exact route
What 3 neurones usually comprise the pathway from the periphery to the CNS?
- Primary afferent (Receptor > spinal cord)
- Cord > thalamus
- Thalamus > cerebral cortex
Describe the pathway used by the cerebral cortex to communicate with muscles
- The corticospinal pathway
What are the two types of pathway and what impluses travel along these?
- Dorsal column pathway
- Tactile sensation
- Proprioception
- Spinothalamic pathway
- Crude tactile sensation
- Pain
What is the vision pathway?
What is the hearing pathway?
Which is the only concious level of processing?
- The cerebral cortex level
What is the somatic sensation pathway?
What is the generic sensory pathway?
What process causes humans movement?
these all input into…
- Cerebral cortex
- Basal Ganglia
- Brainstem Nuclei
- Cerebellum
- Spinal motor neurons
What structures input into the alpha motorneuron?
These either input directly or indirectly (via interneurons)
What 3 classes of information does the somatosensory system carry?
- Exteroceptive - exernal environment (pain,touch,temp)
- Proprioceptive - body position
- Interoceptive - internal (internal pain,unconscious sensation)
