College 7 Flashcards
What does the movement hierarchy consist of?
- Reflexes
- Automated movemens
- Voluntary movements
What are reflexes?
Fixed, rapid, automatic movements triggered in response to a specific sensory stimulus
What is the difference between postural and rhythmic automated movements?
Postural: combi van relex en volition om overeind te blijven
Rhythmic: initiation en termination is voluntary, maar beweging zelf automatisch
What are lower motor neurons?
Project from the ventral horn of the spinal cord
Waar is de motor cortex?
In the frontal lobe, anterior to the central sulcus
When are mirror neurons active?
When performing an action or when observing another individual perdorm a similar action
What are the three cellular layers of the cerebellum?
- Granule cell layer
- Purkinje cell layer
- Molecular cell layer
What is somatosensation?
Tactile and nocicptive (pain) somatosensor feedback helps guide movements
What is proprioception?
Location of your body in a space
How to assess manual dexterity? (4)
Via muscle strength
Motor speed
Fine motor skill
Coordination
How to assess locomotion? (2)
- Gait
- Balance
What are the motor learning stages?
- Early/cognitive– declaritive, self talk
- Associative – detect and eliminate errors
- Autonomous – automatic, frees up working memory
What is the difference between sequence learning and sensorimotor adaptation?
Sequence learning: acquisition of a new motor pattern
Sensorimotor adaptation: ability to adjust movement to changing environment
What is Huntington’s Disease?
A neurodegenerative disease cause by a dominant genetic mutation
–> huntingtin produced, altered form is toxic to the caudate and putamen
What is ideation apraxia?
When you have no idea or concept of what to do with something (sokken over schoenen)
