The cranial and spinal cavities protect the brain and spinal cord.
yes. true
Spinal cord passes through the vertebral foramen of vertebrae C1-C7, T1-T12 and L1 (sometimes L2). Cauda equina (nerve roots of lower spinal cord) pass through the vertebral foramen of vertebrae L3-L5 and the sacral canal. Spinal nerve roots pass through all of the intervertebral foramen and the sacral foramen.
Contemporary craniosacral therapists practice manipulation not only of the skull, but of the meningeal membranes that cover the brain and the spinal cord, and sometimes of the facial bones.
The spinal cord terminates inferiorly as the medullary cone at approximately vertebra L1 and is attached to the coccyx by a continuation of the pia mater. This is known as the terminal filum.
There are meningeal fluids that flow through the brain, and there is a complex webbing of blood vessels known as the blood-brain barrier. The fluids help cushion the brain.
peripheral nervous system
Not much information here in context to efficiently answer the question but I will try. The spinal cord generally ends (terminates) around the L1 vertebral level in the lumbar spinal column give or take a level or so in normal humans. After this, small spinal nerves continue down in a sac and exit the lumbar and sacral spine to innervate the pelvis and lower extremities.
It's called 'cerebro-spinal fluid', and it's found around the cerebrum and spine.
Peripheral: Beyond (in this case, beyond the brain and the spinal cord.) Neuro-: Related to the nerves -pathy: Disease Put these concepts together and this is what peripheral neuropathy means: It refers to the conditions that result when nerves that connect to the brain and spinal cord from the rest of the body are damaged or diseased.
The inflammation of the meninges, brain and the spinal cord is meningoencephalomyelitis. Mening/o-meninges encephal/o-brain; Myel/o-spinal cord/ bone marrow; itis-inflammtion. Meningitis is inflammation of the only the meninges, which are the covering of the brain and spinal cord. Meningitis does not encompass the spinal cord and brain.
