Question

multiple choice question
in the gate control theory of pain, specific receptors in the ______ activate to send pain messages to the brain.

• endocrine system
• spinal cord
• brain
• hippocampus

Explanation:

The gate control theory of pain proposes that the spinal cord contains a "gate" mechanism that regulates the transmission of pain signals to the brain. Specific receptors in the spinal cord activate to send these pain messages, while other signals can close the gate to reduce pain perception. The other options are incorrect: the endocrine system handles hormones, the brain receives pain signals rather than originating them here, and the hippocampus is linked to memory, not primary pain signal transmission.

Answer:

B. spinal cord
