  2. femoral plexus
  3. thoracic plexus

Sacral plexus

The spinal cord is considered an organ which is composed of the nervous tissues. The spinal cord passes through the vertebral column or foramen and based on these foramen is divided into 31 segments from which a bundle of nerves fiber exits.

The spinal cord is divided into the 5 lumbar and 5 sacral division in which the bundle of nerves which exit from the S1 to S4 which are also joined by the L4 and L5 are called the sacral plexus. The sacral plexus is formed of nerves which exit from the spinal cord to the pelvis and the lower limb.

Nezavi [6.7K]

Answer:

c) Nucleoside reverse transcriptase inhibitors may interfere with DNA replication by the host, not just by the virus.

Explanation:

A drug that targets the structures or processes specific to the pathogen or microbe has fewer side effects than the drugs that target the more general structures and processes exhibited by both the pathogen and host cells.

According to the given information, the nucleoside reverse transcriptase inhibitors resemble thymine and terminate the process of DNA replication. Thymine base is also one of the nitrogenous bases present in the human cells and other organisms. Therefore, the nucleoside reverse transcriptase inhibitors would terminate the process of DNA replication in both the virus and the host organism.

On the other hand, the non-nucleoside reverse transcriptase inhibitors specifically target the reverse transcriptase enzyme that is not present in host organisms. Therefore, the non-nucleoside reverse transcriptase inhibitors have fewer side effects than the nucleoside reverse transcriptase inhibitors.
