|
what type of fibers do alpha motor neurons supply
|
extrafusal fibers of skeletal muscle
|
|
what type of fibers do gamma motorneurons supply
|
intrafusal fibers of neuromuscular spindles
|
|
what are interneurons
|
link one neuron to another may converge signal on one neuron or disperse signal to many neurons for control
|
|
what are renshaw interneurons
|
glycergenic interneurons that are excited by collateral processes of excited alpah motorneurons. They act as the off switch inhibiting the alph motorneuron which excited them
|
|
which tracts control the flexor motor system and fine movement
|
corticospinal (lateral and anterior)
rubrospinal tectospinal |
|
which tracts regulate antigravity muscles (extensors) posture and balance
|
reticulospinal tract
vestibulospinal tract (lateral and medial) |
|
what composes the upper motor system
|
nerves from the cerebral cortex to the junction with inter and peripheral nerves
|
|
what composes the lower motor system
|
the interneurons and alpha motor neurons
