WebThe smooth muscles function by stimulating the contractility of the digestive, urinary, reproductive systems, blood vessels, and airways. These smooth muscles are spindle-shaped with a single nucleus. They are under involuntary control, therefore you cannot move these muscles with conscious thought. Structure of smooth muscles WebThis system is mainly concerned with producing movement through muscle contraction. This section explores the different types of muscles in our body and their involvement in …
WebJul 8, 2024 · These voluntary movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message … WebTo summarize, upper motor neurons initiate movement by sending impulses to lower motor neurons which then relay that information to the skeletal muscle. Thus you can say that voluntary movement comes from the top down and reflexes come from the bottom up.
