Motor Control Flashcards
Motor Control
subdiscipline of human movement studies concerned with understanding the processes that are responsible for the acquisition, performance, and retention of motor skills
stages of learning a task
- > cognitive
- > associative
- > autonomous
What are the subcategories of motor control
- > Motor performance
- > motor learning
- > motor development
What are motor skills
- > a learned skill that you are able to do in a variety of scenarios
- > must be voluntary and goal oriented
Components of the nervous system
- > CNS and PNS
- > Efferent and Afferent signals
- > action potential
Sensory systems involved in human movement
- > visual system
- > kinesthetic system
- > vestibular system
Role of visual system in human movement
- Determining location of objects in the external environment (Exteroception)
- Determining the position/orientation of the body relative to the external environment
Role of kinesthetic system
- Determine orientation of body segments relative to each other (proprioception)
- Determine movement of individual body segments
- Determine orientation of the body relative to the external environment
What is the kinesthetic system
- > The kinesthetic system is that part of human physiology that provides each person with. sensory awareness of the position and movements of her or his body
Receptors in the kinesthetic system; what do they do
- Muscle spindles (stretch receptors) - > primarily detect changes in the length of the muscle - > one role: stretch reflex
- Golgi Tendon Organs - > proprioceptive sensory receptor organ that senses changes in muscle tension tells us our muscle is pulling and generating force
- Joint receptors - > tells your brain how your joints are oriented in space (i.e. your knee is bent)
- Touch Receptors - > sensory neuron that are located in the skin and possess specialized endings that respond to mechanical stimulation
Explain the stretch reflex in relation to the patellar nerve
- > when the patellar tendon of the quadricep muscles is stretched, the stretch is detected by the golgi tendon organ which is then detected by stretch receptors (muscle spindles)
- > muscle spindle then stimulates sensory neurons which tells quads to contract
Motor control areas of the brain
* primary motor cortex and primary somatosensory cortex *
Homunculus
grooves of the brain that control a certain body part
Enhanced information processing model
