What is the significance of the spinal cord enlargement?
There are two the cervical and the lumbar. They are enlarged because the cervical gives rise to nerves in the upper limbs and lumbar in the lower limbs thus they have more nerves running to and from which accounts for the enlargements.
What is the significance of the cervical and the lumbar regions?
They are sections of the spine. They are used in medical terminology to distinguish between the four areas of the spine and back: the cervical region (neck), the thoracic region (upper torso/shoulder blade area), the lumbar region (waist/low back area) and the sacral/coccygeal region (lowest part of back and tail bone/coccyx).It is often in these two areas, the cervical and the lumbar, areas that people have injuries, strains, sprains, and chronic pain. The cervical area is where whiplash occurs and the lumbar and lumbo-sacral areas are the most common regions for low back injuries and pain.
Why are the cervical and lumbar regions enlarged in the human spine?
The cervical and lumbar regions of the human spine are enlarged to provide support and flexibility for the head and torso, as these areas bear the most weight and movement in the body.
What two regions is the spinal cord enlarged?
the spinal cord is enlarged at the region from where the plexus originate so it is enlarged at the cervical from where the roots for brachial plexus originates the and thoracolumbar level where the cauda equina originates
From what areas of the CNS does each division originate?
The parasympathetic originates from the brain and spinal cord. The sympathetic originates from the thoracic and lumbar spinal nerves.
What does lumbosacral junction is assumed l5 s1 mean?
Your spinal cord is made up of 5 different areas, based on how many vertebrae (pieces of spine) make it up. You have: 7 CERVICAL 12 THORACIC 5 LUMBAR 5 SACRAL 5 COCCYGEAL Therefore the lumbosacral junction (where lumbar meets sacral) is assumed to be at L5 (the 5th and last lumbar vertebrae) and S1 (the 1st sacral vertebrae).
Spina Bifida seen at level 1 noted. What does that mean?
Spina Bifida occurs on the spinal cord .The spinal cord is divided into different areas for labelling .The bottom is the sacral area, which is divided in sections S5-S1, then the next area is Lumbar L5-L1, the next section is Thoracic T-12-T1 and finally the last section cervical C8- C1. I would assume if it said L1 that it means Lumbar section 1 where the lesion or mark is on the back.
How many spinal vertebra does a human have?
There are 33 vertebrae in the spinal cord of a human being. They are broadly categorized into 5 areas. They are called the cervical, thoracic, lumbar, sacrum & coccyx vertebra. The upper 3 areas have a total of 24 vertebrae, which includes 7 cervical vertebrae, 12 thoracic vertebrae & 5 lumbar vertebrae. Sometimes the lumbar region, may have an additional vertebra, it does happen - but it is rare. 5 vertebrae are fused together to form the sacrum & 3 vertebrae form the end of the spinal column which is the coccyx.
How many different regions are found on the spinal column?
The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body – 24 separate vertebrae interspaced with cartilage plus the sacrum. The last is the coccyx which is not interspaced with cartilage. The spinal column is divided into 5 different areas grouped into seven cervical vertebrae in the neck, twelve thoracic vertebrae (corresponding to each pair of ribs), five sacral vertebrae which are fused together to form one bone called the sacrum.
Where does a disk herniation most often occur?
A disk herniation most often occurs in the lower back (lumbar spine) or the neck (cervical spine). These are the areas of the spine that experience the most movement and stress, making them more susceptible to injury.
What part of the body does Cervical 5 and 6 control?
Cervical 5 and 6 control the function of the muscles and sensations of the upper extremities, particularly the shoulders, arms, and hands. Damage or issues with these spinal levels can lead to weakness, numbness, or pain in these areas.
What part of the body is the spine?
Firstly, the spine is separated into three separate types of vertebrae: the first seven starting at the base of the skull are the cervical vertebrae (and the first specifically being the atlas and second the axis), the next twelve are the thoracic vertebrae, and the last five are the lumbar vertebrae. The spine ends with the large sacrum bone and then ends with the coccyx (tailbone). between these vertebrae are disks of hyaline cartilage. The vertebral column houses the spinal cord. The spinal cord branches out between each vertebrae with nerves that lead to different areas of the body.
