Test 2: Movement Flashcards
“Upper” motor neurons
The Brain and Frontal Lobe
“Lower” motor neurons
Spinal Chord (works independent of rest of brain)
Cerebellum
Contains 1/10 of nervous system, and the majority of neurons.
Ventral part of Spinal Chord
Motor Part
Dorsal part of Spinal Chord
Sensory Part
“Ventral Horn” part of Spinal Chord
Start of Motor Neurons
Neuromuscular Junction
space between neuron and muscle fibre
neurotransmitter responsible for movement
Actylcoline
Cerebellum functions:
Coordination, rhythm, magnitude, accuracy, and timing of movement
“Forward Model”
Cerebellum predicts future events/movements
Somatotopic
“body placement” cerebellum is broken up based on the body part it controls.
Purkinje Cells
adjust synaptic connection to associate actions with the context in which they’re performed
basic movements are give by the _____ of the prefrontal cortex
Front
complex movements are given by the _____ of the prefrontal cortex
Back
Frontopolar Cortex Role:
Long-term goals and multitasking with no sensory input
Prefrontal Cortex Role:
Forms needs, goals, strategies, tactics, and actions in combination with ongoing sensory information
Prefrontal Cortex areas each have a planning partner in the ______.
Parietal Lobe
Mirror Neurons partner is the ________.
superior temporal sulcus (detects others goals)
Medial Motor Systems
controls movements guided by internal states/motivations
Lateral Motor Systems
controls movements guided by external stimuli
