Control Mechanisms in Locomotion Flashcards
the ability to move from one place to another
locomotion
what are the 3 requirements for locomotion
progression
postural control
adaptation
ability to coordinate and sequence rhythmic patterns and muscle activation of arms, legs, and trunk to successfully mobilize to a desired location
progression
organization of multiple systems to stabilize and orient the body
postural control
ability to adapt locomotion, maintain postural control, and change task based on environmental demands
adaptation
connections within the spinal cord that produce rhythmic alternating flexor and extensor activity in spinal locomotion without surpraspinal input
central pattern generators (CPG’s)
control from higher level brain centers helps coordinate and adapt locomotion
central control
how does the cerebellum receive input from body
spinocerebellar tract
cerebellum sends modulating signals to the brainstem and are relayed to the spinal cord via
brainstem nuclei
lies at based of cerebral cortex in which it receives information from the cortex and sends output to the motor cortex via thalamus; helps with planning and motor strategies with movement
basal ganglia
integrates sensory signals, perception, memory and conscious will
cerebral cortex
integrates with posterior partietal and inferotemporal cortex and integrates visual information into recognizable objects and have meaning to person
visual cortex
both of these use sensory feedback and direct appropriate spatially directed locomotor movements that have meaning for the person
frontal cortex and basal ganglion
cortical blindness
visual cortex
difficulty with planned movements, spatial reasoning, attention
posterior parietal
