in the context of pathways in the nervous system, afferent nerves carry information:
○ out of the brain and spinal cord to other areas of the body.
○ out of the endocrine system to muscles and glands in the body.
○ to the brain and spinal cord via sensory receptors.
○ to the heart and lungs from the muscles and glands.

Explanation:

To solve this, we recall the definition of afferent nerves (sensory nerves) in the nervous system. Afferent nerves transmit sensory information from sensory receptors (like in skin, eyes, etc.) to the central nervous system (brain and spinal cord).

• The first option describes efferent (motor) nerves.
• The second option is incorrect as afferent nerves are part of the nervous system, not endocrine, and don't carry info from endocrine to muscles/glands.
• The fourth option is incorrect as afferent nerves don't target heart/lungs from muscles/glands.
• The third option matches the function of afferent nerves (carrying info to brain/spinal cord via sensory receptors).

Answer:

C. to the brain and spinal cord via sensory receptors.
