You asked: What anchors spinal cord laterally?

What structure anchors the spinal cord laterally to the vertebrae?

The denticulate ligaments are fibrous structures that help to anchor the spinal cord in place. The posterior spinal arteries supply the dorsal spinal cord with blood and run just medial to the dorsal root entry zone.

What extends laterally from the spinal cord?

The cord is stabilized within the dura mater by the connecting denticulate ligaments, which extend from the enveloping pia mater laterally between the dorsal and ventral roots. The dural sac ends at the vertebral level of the second sacral vertebra.

What holds spinal cord in place?

The spinal cord is held in place by the filum terminale, a slender extension of dural linings that run from the conus medullaris (end of the spinal cord) to the coccyx. In addition, 21 pairs of denticulate ligaments attach the spinal cord to the arachnoid mater and dura mater. These ligaments are formed from pia mater.

What extends laterally from the spinal cord and attaches to the dura mater?

The pia mater has paired specializations called denticulate ligaments, which extend laterally from the surface of the spinal cord and pierce the arachnoid to attach to the inner aspect of the dura mater at 21 pairs of denticulations (dentate means tooth-like – these are tooth-like lateral projections).

Which spinal nerves affect which parts of the body?

The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.

What happens if your spinal cord hurts?

Emergency signs and symptoms of a spinal cord injury after an accident include: Extreme back pain or pressure in your neck, head or back. Weakness, incoordination or paralysis in any part of your body. Numbness, tingling or loss of sensation in your hands, fingers, feet or toes.

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 does the ventral root of a spinal nerve contain?

The Ventral Root of the spinal nerve contains outgoing, efferent (meaning to “bear away from”) fibers that carry information destined to control motor or glandular function. The cell bodies of these motor neurons are located in the ventral horns of the spinal cord’s central grey region.

Which area of the spine is most impacted when moving and handling?

The most vulnerable areas of the spine are the lumbar (lower back), and the cervical (neck) regions. They are the most mobile, and susceptible to injury. The lower back is also the main weight bearing part of the spine.
