Corticospinal Tract

What is the descending tract called

corticospinal

What do descending tracts innervate

skeletal muscles

Where do descending tract motor functions start

primary motor cortex

Where is the primary motor cortex located

frontal lobe

What are the neurons in the descending tract called

upper and lower

In the brain the axons of descending tracts move through a structure of the cerebrum known as the

internal capsule

Which tracts are associated with the internal capsule

descending tracts

Location of the cell body of the upper motor neuron in descending tract

primary motor cortex

Bump on the medulla oblongata

pyramid lateral

Tracts that decussate at the level of the medulla oblongata will now be referred to as

lateral corticospinal tract

Tracts that remain ipsilateral past the level of the medulla oblongata will be referred to as

anterior corticospinal tract

Where will most fibers decussate

medulla oblongata

What tract will 75% of upper motor neurons decussate to

lateral corticospinal tract

Location of the cell body of the lower motor neuron of the lateral corticospinal tract

contralateral ventral gray wing

Location of lateral corticospinal tract decussation

medulla oblongata

Which neuron will decussate for lateral corticospinal tract

upper motor neuron

Which neuron will decussate for anterior corticospinal tract

upper motor neuron

Location of both cell body neurons are found

controlateral ventral gray horn

Where do both neurons exit out of

ventral gray horn

Location of the cell body of the lower motor neuron of the anterior corticospinal tract

contralateral ventral gray horn

Location of anterior corticospinal tract decussation

medulla oblongata

Location of decussation for anterior corticospinal tract

at the level where the lower motor neuron exits the spinal cord

How many locations of decussation
