Pyramids

Paired white matter structures in the medulla oblongata containing the corticospinal tracts, crucial for voluntary motor control.

Key Functions:

• Contain the corticospinal tracts, mediating voluntary motor commands.
• Site of pyramidal decussation, where most motor fibers cross to the contralateral side.
• Involved in fine motor control and skilled movements.

Interacting Systems & Components:

• Medulla Oblongata (located in)
• Spinal Cord (descending tracts extend to)
• Primary Motor Area (originates from)
• Corticospinal Tract (constitutes)
