Question

Identify the specific function and location (plexus of origin) of the phrenic nerve and the sciatic nerve.

a. Phrenic Nerve - Motor control of facial μscles, Sciatic Nerve - Upper limb sensation
b. Phrenic Nerve - Diaphragm movement, Sciatic Nerve - Vision and eye control
c. Phrenic Nerve - Breathing control, Sciatic Nerve - Lower limb sensation
d. Phrenic Nerve - Digestive system control, Sciatic Nerve - Hearing and auditory function

Answer 1

The phrenic nerve controls diaphragm movement and is located in the cervical plexus. The sciatic nerve is responsible for lower limb sensation and comes from the sacral plexus.

Step-by-step explanation:

The phrenic nerve is responsible for diaphragm movement, which controls breathing. It is a systemic nerve located in the cervical plexus. On the other hand, the sciatic nerve is primarily associated with lower limb sensation. It is a combination of the tibial nerve and the fibular nerve and originates from the sacral plexus.
