Our spine protects, maintains our posture and even helps to distribute the gravity lines that travel through our bodies 🕴=♥️.
There are 7 cervical vertebrae (neck), 12 thoracic vertebrae (mid back), 5 lumbar vertebrae (low back), 5 sacral vertebrae fused (pelvis), and 4 coccygeal (coccyx) vertebrae (tail bone). These all together give us our entire spine that support, protect, provide posture and also give rise to different functions both anatomically, physiologically, and in biomechanics. Our cervical spine is responsible for movements/sensations of the upper extremities and also for breathing and communicate directly with our sympathetics and parasympathetics. The mid back is more related to digestion via the sympathetics called the greater splanchics (digestive communications) and house our ribs and joints; costo-vertebral joints, and costo-thoracic joints. The lumbar spine is involved with lower digestion through the lesser splanchics and where we receive motor and sensory functions for our lower extremities. The sacrum houses the gynological for males and females and makes up the sacroiliac joint and gives sensation to reproduction, and the coccyx is primarily involved with the attachements for our pelvic floor muscles. •
If there is an issue with the lumbar spine, then the cervical spine will be affected at either the same or opposite vertebrae. Meaning, L4 is in somatic pain, then C2/C3 will have a similar or same somatic issues as well. The relationships also include the embryological relationship that they all come from mesoderm (embryological cells for muscles, bones, ligaments..). What’s also interesting, is embryological law states that the veins, lymphatics, arteries develop before our skeletal structure, and that the spine actually grows after the heart and its vessels develop. The ascending and descending sorta actually are adhered to the vertebral column and becuase of this, you don’t have a spine per say, you have vessels that is actually the spine and the vertebrae act as a protection 🧠💥. Do you have back pain? Leave a comment and or if you have a questions send a DM.
