The spinal cord itself has a protective myelin sheath that acts as insulation for individual nerves which increases nerve efficiency so signals from the brain can travel faster. Other portions of the spinal cord include white matter made up of nerve fibers (axons) surrounding a vaguely butterfly-...
What makes up the thoracic cavity? What is the parietal bone? What does the myelin sheath do in a nerve cell? Which cranial nerve connects with the optic disc? What does the pleural cavity do? What is the pleural cavity? Which cavities of the human body are lined with mucous membrane?
What makes up the peripheral nervous system?An Important Bodily System:Our nervous system as a whole is made up of nerves, the spinal cord and brain. The nervous system allows us to sense the world around us and process information, and helps our body to function properly....
A condition such as a stroke or spinal cord injury can damage nerves and muscles that make the rectum work. Rectal muscles may be too weak to hold your rectum in place. Pelvic surgery can damage the nerves, muscles or ligaments of the rectum.What are the signs and symptoms of a rectal ...
the body of each vertebra; this is theposterior longitudinal ligament. It also runs all the way down the spinal column. These spinal ligaments reinforce the stability of the spinal column, resist excessive flexion and extension of spinal segments, and protect the spinal cord from compression ...
Tethered spinal cord syndrome is a rare neurological disorder where the spinal cord is attached, or tethered, to the tissues around the spine. This tethering of the spinal cord restricts its movements and prevents it from keeping up with its ongoing growth as the body grows. This causes the ...
What makes them better or worse? Depending upon the circumstances, the patient may not have insight or may not remember the symptoms or complaints, and it may be up to a family member, caregiver, or friend to supply the appropriate information. ...
Permanent paralysis. Occurs from a hematoma when there’s a buildup of blood between the dura mater and the spinal cord. It’s important to remember that these long-term effects are uncommon. Most people experience no lasting issues after an epidural. If you have any concerns or notice unusu...
The brain is divided into many different areas that perform many different functions. The brainstem is an area that is located at the base of the brain on the side closest to thebackof the neck. It connects the brain to the spinal cord. ...
When activated, these receptors send signals along the nerve fibres to the spinal cord and up into the brain, where pain, as a perception, emerges. The nociceptors can be activated by a variety of triggers: thermal (heat), mechanical (like a knife cut or hammer blow) and chemical/...
