The regions of the spine for chiropractors are the cervical region, the thoracic region, lumbar region, sacrum region and the Coccyx region.
The cervical region of the spine is the neck region that contains 7 vertebrae (C1-C7).
The thoracic region of the spine is the upper and mid back which contains 12 vertebrae (T1-T12).
The Lumbar region of the spine is the lower back, which contains 5 vertebrae (L1-L5).
The sacrum region of the spine is made up of 5 used vertebrae (S1-S5 and connects your spine to your pelvis.
The Coccyx region of the spine is the tailbone and is made up of 4 fused vertebrae.
The L5 S1 column is the spinal segment that is located at the very bottom of your lower back and where the lumbar spine L5 vertebra meets up with the sacrum or S1 vertebra.
The L5 S1 column is also the transition point between your lumbar curve and your sacral curve and is vulnerable for potential back pain and disc herniation as a result of the high stress that it experiences.
The L4 and L5 spinal column are the 4th and the 5th vertebrae in your lumbar spine and is located in your lower back.
Your L4-L5 spinal motion segment and includes the soft tissues, joints, nerves, intervertebral disc and vertebrae and supports your upper body and allows the trunk to also move in many different direction.
Your L4 and L5 vertebrae are also larger than other vertebrae in your spine and are much more likely to develop pain and degenerative changes because of the weight bearing function and ability that they have.
The four columns of the spinal cord GREY matter are the ventral horn, dorsal horn, lateral horn and intermediate column.
The GREY matter when looking at a cross section of your spinal cord is divided into the 4 columns and each section contain different types of neurons that are responsible for specific functions.
The ventral horn contains motor neurons which send signals to your muscles.
The lateral horn is only present in certain spinal cord segments and are primarily involved in the autonomic nervous system.
The intermediate column contains various interneurons which connect different parts of your spinal cord.
And the dorsal horn mainly receives sensory information.
The spinal column is also called the vertebral column or the backbone.
The backbone, spinal column and vertebral column are all terms that mean the same thing and refer to a series of bones which run from the base of your skull to your tailbone and support your body and also protect your spinal cord.
Humans only have one spinal column although the one spinal column is made up of 33 individual bones called vertebrae that are stacked together.
But by adulthood, some of the vertebrae at the bottom of our spine fuse together and result in most people having 24 moveable vertebrae.
The columns in the spinal cord are the posterior column, middle column and the anterior column.
The posterior column is everything that is posterior to the PLL and the pedicles.
The middle column is the posterior one third of the vertebral body and the posterior one third of the intervertebral disc.
The anterior column is the anterior longitudinal ligament and the anterior two thirds of the vertebral body.
The difference between the spinal cord and the spinal column are the spinal column is a stack of bones which protects your spinal cord.
And the spinal cord is a bundle of nerves and tissues which run inside your spinal column.
The spinal cord is a tube shaped bundle of nerves and tissues which is part of your central nervous system and runs from the base of your brain stem to the lower back and is also surrounded by cerebrospinal fluid and covered by your meninges.
Your spinal column also protects your spinal cord with shock absorbing spinal disks between each vertebra and the spinal cord also sends signals to your brain through nerve tracts that carry different types of sensations in different pathways.
The function of the spinal column is to provide the body with structural support and allow movement while also protecting your spinal cord.
The spinal cord is a bundle of nerves that connect the brain to the rest of your body and acts as a central axis of your body and enables flexibility and movement as well as posture by transferring weight from the trunk to your legs.
The 5 columns of the spine are the cervical spine, thoracic spine, lumbar spine, sacral spine and the coccygeal spine.
The cervical spine are the 7 bones in your neck, with the first vertebra that supports the skull.
The Thoracic spine is the 12 bones in your back area.
The lumbar spine is the 5 bones in your lower back area.
The Sacral spine are the 5 sacral bones which fuse into one bone in adulthood.
The Coccygeal spine is the four coccygeal bones which fuse into one bone in adulthood, though the number can vary from 5 to 3.
A column in the spinal cord is a column of bones which protect your spinal cord.
Your spinal column also contains the ligaments which connect your vertebrae together.
