One important branch of the cervical plexus is the nerve, which is formed primarily from the nerve and some contributing axons from . this nerve travels through the cavity to innervate and is important for breathing.

The answers are: phrenic nerve, cervical spinal nerve, branches of the cervical plexus,  the thoracic, and the root of the lung to reach the diaphragm.

Explanation:

One important branch of the cervical plexus is the phrenic nerve, which is formed primarily from the   cervical spinal  nerve and some contributing axons from branches of the cervical plexus.

This nerve travels trhought the thoracic cavity to innervate the root of the lung to reach the diaphragm and its important for breathing.

This question is about the network of nerve fibres that supplies innervation to some of the structures in the neck and trunk.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

i think its the first one
