What are the entry and exit points for the gall bladder meridian?

The gall bladder meridian begins at GB-1, known as Tong Zi Liao, which is located at the outer canthus of the eye. This point is crucial as it marks the start of the gall bladder's pathway, influencing functions related to digestion and the liver's health.

The exit point for the gall bladder meridian is GB-41, referred to as Zu Lin Qi. This point is located on the dorsum of the foot, in the space between the fourth and fifth metatarsal bones. The travel of the gall bladder meridian from GB-1 to GB-41 signifies its entire pathway through the body, connecting to various organs and influencing the flow of Qi.

GB-41's role as the exit point indicates the culmination of the meridian's energy, highlighting its importance in TCM practice for treating disorders related to the gall bladder, such as those affecting digestion, bile flow, and emotional balance.

The other options do not correctly identify the exit point as GB-41, thereby failing to accurately represent the gall bladder meridian's pathway. This reinforces the significance of both entry and exit points in TCM meridian theory and their relevance to overall health.
