There are 8 cervical nerves because the first 7 nerves exits on the upper part of the vertebrae making up 7 nerves but then on the 7th vertebrae there's another nerve that exits below the vertebrae thus making up 8 cervical nerves from 7 cervical vertebrae.
The phrenic nerve arises from the cervical plexus, specifically from nerve roots C3, C4, and C5. It travels down through the thorax to innervate the diaphragm, playing a crucial role in breathing.
The nerves that control the diaphragm exit the central nervous system from the cervical spinal cord, specifically from the C3 to C5 nerve roots. These nerve roots come together to form the phrenic nerve, which is the primary nerve responsible for controlling the movement of the diaphragm during breathing.
The nerve that control the larynx during breathing is the Vagus Nerve.
There are 31 pairs of spinal nerves because the first cervical nerve exits above the first cervical vertebra. The remaining spinal nerves exit below their corresponding vertebrae. Therefore, there is one more pair of spinal nerves than there are vertebrae in the spinal column.
The phrenic nerve arises from the cervical plexus (C3-C5) and supplies the diaphragm, which is the primary muscle involved in breathing.

Cervical stenosis is a condition in which the spinal canal is too small for the spinal cord and nerve roots. This can cause damage to the spinal cord.
Cervical plexus....

There are 31 pairs of spinal nerves because the first cervical nerve exits above the first cervical vertebra. The remaining spinal nerves exit below their corresponding vertebrae. Therefore, there is one more pair of spinal nerves than there are vertebrae in the spinal column.
There are more than 3 nerves in the cervical plexus. The most important nerve here is the phrenic nerve, which supplies the diaphragm, from roots C3-5. Other deep branches include the ansa cervicalis and segmental branches; the superficial branches are the lesser occipital, great auricular, transverse cervical and supraclavicular.
Compression of the left cervical nerve roots,supplying left hand. could be due to, cervical PID, LYSTHESIS, CANAL STENOSIS...CERVICAL SPONDYLOSIS.........etc. also due to -improper posture, improper ergonomics.
Yes, the spinal nerve C8 exits between the C7 and C8 vertebrae. In the cervical region, there are eight cervical spinal nerves (C1 to C8), but only seven cervical vertebrae. Therefore, the C8 nerve root exits below the C7 vertebra and above the C8 vertebra, which is why it is uniquely positioned.
Yes, you may still have a stretch reflex with a cervical nerve injury.
The phrenic nerve, which arises from the C3-C5 nerve roots in the cervical spine, innervates the diaphragm muscle and controls its function. Dysfunction of the phrenic nerve can impair breathing and lead to respiratory issues.
