The region of the spinal cord responsible for transmitting sensory information toward the brain is the:AVentral hornBDorsal hornCLateral hornDCentral canal

To identify the region of the spinal cord responsible for transmitting sensory information toward the brain, let's analyze the options provided:

1. Ventral Horn:

   • Primarily associated with the motor neurons that send signals to muscles.
   • Responsible for transmitting motor functions rather than sensory information.

2. Dorsal Horn:

   • Contains sensory neurons that receive incoming sensory information.
   • Plays a crucial role in relaying this information to the brain for processing.

3. Lateral Horn:

   • Associated with autonomic functions and contains neurons that are primarily linked to the sympathetic nervous system.
   • Does not primarily deal with sensory information.

4. Central Canal:

   • A space within the spinal cord that contains cerebrospinal fluid.
   • Does not play a role in transmitting sensory or motor information.

Final Answer

The region of the spinal cord responsible for transmitting sensory information toward the brain is the Dorsal Horn (B).
