Descending (motor) pathways always involve at least two motor neuron(s). The correct option is B.

Descending tracts are the pathways by which motor signals are sent from the brain to the spinal cord. They are also called motor neuron tracts, due to their involvement in movement coordination.

Each descending tract is formed by 2 interconnecting neurons. Together these create a pathway from the upper neural structures in the brain to the target effector muscles. First-order neurons are upper motor neurons (UMN). They arise from the cerebral cortex and travel down the spinal cord to synapse in the anterior gray horn.

(1) To fill a 20-days supply is needed for HIV treatment regimen = 268 tablets.

(2) The patient will take 68200 mg in 22 days

(3) The drugs that comprise Truvada is tenofovir and emtricitabine.

Abacavir: 300 mg twice daily equals 600 mg per day over 20 days, 12,000 mg over 1 tab at 100 mg, and 120 tabs.

Lexiva: 1 morning dose of 700 mg equals 700 mg.

2 in evening of 700 mg equals 1400 mg.

Total = 2100 mg each day x 22 days, which comes to 46,200 mg in 22 days.

The recommended dosage for fosamprenavir (Lexiva) is one 700 mg tablet taken orally in the morning and two 700 mg tablets taken orally in the evening.

Take 4 tabs of 100 mg of the medication Isentress (raltegravir) orally 4 times per day.

Hence, to fill a 20-days supply is needed for HIV treatment regimen = 120 tabs + 60 tabs + 88 tabs) = 268 tablets

ANd in 22 days:

Abacavir (600 mg x 22) = 13200 mg

Lexiva (2100 mg x 22) = 46200 mg

Isentress (400 mg x 22) = 8800 mg

Total = 68200 mg

Tenofovir and emtricitabine, the two drugs that combine to form Truvada, block crucial pathways that viruses utilize to initiate infection.
