The posterior ramus of a typical spinal nerve innervates the

Deep muscles of the back and the skin of the back.

Explanation:

Spinal nerves are the nerves which originate from the spinal cord of the central nervous system and are involved in the locomotion of the limbs and the trunk of the body.

Each spinal nerve is formed of the axons of the motor neurons (dorsal) and the sensory neurons (ventral root). These root structures unite and split into the dorsal or posterior ramus and the ventral or anterior ramus.

The dorsal ramus supplies the nerves to the dorsal part of the body that is the muscles of the back, dorsal muscles and the skin of the dorsal muscles.

Thus, Deep muscles of the back and the skin of the back is correct.

The posterior ramus of a typical spinal nerve innervates the: deep muscles of the back and the skin of the back. The anterior ramus of a typical spinal nerve innervates the: anterior and lateral trunk and the limbs.

Explanation:

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
