which spinal nerve innervates the main important muscle for our respiration and to which plexus of the peripheral nervous system does it belong to
Homework Answers
The phrenic nerve innervates the diaphragm,which is the most important muscle responsible for breathing.The phrenic nerve originates from the C3-C5 of the neck.The nerve enters the thoracic cavity and travels between the lungs and the side of the heart to finally reach the diaphragm.The phrenic nerve belongs to the cervical plexus of the peripheral nervous system.It provide motor innervation to the diaphragm.

Which statement best describes the function of the nervous system? The nervous system senses stimuli via efferent pathways and sends response signals. The nervous system senses stimuli, integrates information, and generates a response. The nervous system consists of the brain and spinal cord, which are linked to each other by peripheral nerves. The nervous system signals muscle contraction but does not control gland secretion.
