Spinal Nerve Anatomy Humans have 31 left–right pairs of spinal nerves, each roughly corresponding to a segment of the vertebral column: eight cervical spinal nerve pairs (C1–C8), 12 thoracic pairs (T1–T12), five lumbar pairs (L1–L5), five sacral pairs (S1–S5), and one coccygeal pair.
How many spinal nerves are present in human body?
31 pairs
In total, there are 31 pairs of spinal nerves, grouped regionally by spinal region. More specifically, there are eight cervical nerve pairs (C1-C8), twelve thoracic nerve pairs (T1-T12), five lumbar nerve pairs (L1-L5), and a single coccygeal nerve pair.
What are the 4 spinal nerves?
There are eight cervical, twelve thoracic, five lumbar, five sacral nerves and one coccygeal nerve (all in pairs), each one emerging out of their corresponding intervertebral foramina (bony openings) of the vertebral canal.
Why does the 33 vertebrae have 31 spinal nerves?
The low back bears the weight of the upper body and has the largest vertebrae. The sacral region has five vertebrae that are fused together and the coccygeal region is made up of four tiny fused vertebrae. The 31 pairs of spinal nerves are named after the vertebrae that they come out from.
What are the spinal nerves called?
There are eight pairs of cervical nerves, twelve pairs of thoracic nerves, five pairs of lumbar nerves, five pairs of sacral nerves, and one pair of coccygeal nerves. The spinal nerves are part of the peripheral nervous system.
What does C5 C6/C7 control?
Roots C5, C6, and C7 produce the long thoracic nerve, responsible for controlling the serratus anterior.
What nerve is between C4 and C5?
Branches of the C3, C4, and C5 spinal nerves form the phrenic nerve that innervates the diaphragm, enabling breathing. Within the spinal canal of each of these motion segments, the spinal cord is protected by the vertebral bodies in front and vertebral arches at the back.
