Areas Of The Brain Involved In Motor Function Flashcards
What are Lower motor neurons called?
Pyramidal neurons
Where do lower motor neurons synapse?
With Skeletal muscles and form a single motor unit and when activated it causes skeletal muscle to contract
Where are the UMN located?
Various regions of foreboding responsible for planning coordination and executing motor commands

What are the 3 layers of the cerebellar cortex?
Molecular Layer
Purkinje Layer
Granule cell Layer
What is the Basal Ganglia known as?
Cerebral nuclei
What are the structures of the Basal ganglia?
Caudate nucleus
Lentiform nucleus(Lateral putamen and medial globes pallidus)
What are the 2 subdivisions of the Globus palladus?
GPEXT AND GPINT
What do the putamen and globes pallidus form?
Lentiform nucleus
What are the subdivisions of the Substantia nigra?
Pars compacta(dopamine)
Pars reticula(GABA)
What is the function of the Basal ganglia?
Eliminate unnecessary movements
Regulate attention and cognition
