Nerve roots in the spine are the key component of intervertebral disks. a. true b. false

The correct answer is - false.

Explanation:

The nerve root is the beginning part of a nerve that leaves CNS and the spinal cord. It is the initial part of the nerve that is present in between the intervertebral disks and runs through spines which acts as a shock absorber and protects these nerves to any type of damage to these nerves.

The nerve root is not the component of the inter-vertebral disks but initial part of the nerves which are protected by these shock absorbers.

Thus, the correct answer is - false.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
