Cards

Term
List the processing levels of the CNS in order from top to bottom.
Definition
Cerebral Cortex
Diencephalon
Cerebellum
Brain Stem
Spinal Cord
Term
The spinal cord has a simple relationship between sensory and motor input. (3)
Definition
1. Organization of reflexes
2. Simple responses to sensory input
3. Flexion/extension patterns associated with leg movements
Term
Involved with postural control and locomotion
Definition
Brain stem
Term
Does the brainstem contain sensory and motor pathways (ascending and descending)?
Definition
Yes
Term
Reticular formation in the brain stem regulates what?
Definition
Arousal
Term
Gets input from the spinal cord: feedback regarding movement
Definition
Cerebellum
Term
Gets input from the cortex: information on planning movements
Definition
Cerebellum
Term
Coordinates motor responses and is involved in motor learning
Definition
Cerebellum
Term
Accepts and sifts all sensory information
Definition
Thalamus
Term
Processes information from the spinal cord, cerebellum, and brainstem
Definition
Thalamus
Term
Name 5 things in which the thalamus is involved in.
Definition
1. Memory
2. Learning
3. Arousal
4. Abstract Thinking
5. Long-term goal oriented behavior
Term
Links the nervous system to the endocrine system
Definition
Hypothalamus
Term
Provides hormonal control and regulates areas for thirst, hunger, body temperature, water balance, and blood pressure.
Definition
Hypothalamus
Term
The processing area for kinesthetic and touch sensations.
Definition
Somatosensory cortex
Term
Supplementary motor area
Definition
Internal Stimulus
Term
Pre motor cortex
Definition
External Stimulus
Term
2 areas of the cerebral cortex that are involved in planning and initation of movement
Definition
supplementary motor cortex
Pre motor cortex
Term
Interacts with sensory processing areas, basal ganglia, cerebellum, and primary motor cortex
Definition
Cerebral cortex
Term
Helps to plan movement
Definition
Basal Ganglia
Term
Receives input from multiple sources. Outputs to motor neurons. Controls force and speed of movement. Multiple parallel pathways.
Definition
Primary Motor Cortex
Term
Fast movements will __ spasticity
Definition
Increase
Term
Small catches between rigidity
Definition
Cogwheel
Term
No movement at all is what type of rigidity
Definition
Lead Pipe
Term
How fast motor units are recruited repetetively
Definition
Discharge Frequency
Term
L CVA injury results in __ body neglect
Definition
Right
Term
Being able to recognize an object by touching it and not looking at it
Definition
Sterognosis
