The lowermost tapering extremity of the spinal cord is called the conus medullaris, which is around the first or second lumbar vertebra and can sometimes be lower.
What is tapered at the end of the spinal cord?
The most distal bulbous part of the spinal cord is called the conus medullaris, and its tapering end continues as the filum terminale. Distal to this end of the spinal cord is a collection of nerve roots, which are horsetail-like in appearance and hence called the cauda equina (Latin for horse’s tail).
What is the structure that anchors the lower end of the spinal cord to the first coccygeal vertebra?
Distally, the meninges form a strand of fibrous tissue, the filum terminale, which attaches to the vertebral bodies of the coccyx. It acts as an anchor for the spinal cord and meninges.
What is the conus medullaris in the spinal cord?
The conus medullaris is the terminal end of the spinal cord, which typically occurs at the L1 vertebral level in the average adult.  Conus medullaris syndrome (CMS) results when there is compressive damage to the spinal cord from T12-L2.
What part of the spinal cord represents an increase in cell body?
The cervical and lumbar regions of the spinal cord show a larger diameter compared to the rest of the regions. The cervical enlargement and lumbar enlargement represent an increased amount of neurons in the gray matter and axons in the white matter that serve the upper limbs and lower limbs, respectively.
What is the gray commissure of the spinal cord?
a bundle of nerve fibers that surrounds the central canal of the spinal cord and connects the anterior and dorsal horns of gray matter in each half of the cord.
What is the main function of the spinal cord?
The brain and spinal cord are your body’s central nervous system. The brain is the command center for your body, and the spinal cord is the pathway for messages sent by the brain to the body and from the body to the brain.
What part of the spine controls the heart?
Thoracic (mid back) – the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12.
What is the best treatment for cauda equina syndrome?
Cauda equina syndrome is best treated with decompression by a lumbar laminectomy, but a lumbar microdiscectomy may be used given a patient’s unique situation. The patient will likely be kept in the hospital for a few days following the surgery to monitor recovery of motor and sensory function.
How do I know if I have cauda equina syndrome?
Typical symptoms of cauda equina syndrome include: Neurological symptoms in the lower body. Weakness, tingling, or numbness in the legs, and/or feet on one or both sides of the body is a common symptom. Lower body weakness or numbness may make it difficult to walk or stand.
