Wise, Eddie Johnson, Brandon Poe, Dean H. Kruse, Oksana Korol, Jody E. Johnson, Mark Womble, Peter DeSaix. Think about lobes, nuclei, ganglia, tracts, etc. Skeletal muscles generate heat as a byproduct of their contraction and thus participate in thermal homeostasis. Constriction of smooth muscle occurs under involuntary, autonomic nervous control in response to local conditions in the tissues. It transports O2, waste product. Skeletal muscles control voluntary movements which can be consciously controlled. Skeletal muscles generate heat as a byproduct of their contraction and thus participate in thermal homeostasis.
