 Leg Tai Yin: Spleen Sinew Channel

 ·  Begins at the medial side of the big toe at Yīnbài SP-1

·  Ascends the foot to bind at the medial malleolus at Shāngqiū SP-5

·  Ascends the medial aspect of the tibia to bind at the medial side of the knee at Yínlíngquán SP-9

·  Follows the medial face of the thigh to bind in the groin before converging at the external genitalia

Lower Body (Leg Deep Line)

Nerves:

1. Spinal Nerves:
• L1-L5 (Lumbar Plexus): Innervates the muscles of the lower abdomen and thigh, including the iliopsoas and adductors.
• S1-S4 (Sacral Plexus): Innervates the muscles of the pelvis and lower limbs, including the pelvic floor muscles and deep muscles of the leg.

Reflexes:

1. Babinski Reflex: Involves dorsiflexion of the big toe and fanning of the other toes when the sole of the foot is stroked.
2. Plantar Reflex: Involves flexion of the toes and foot in response to stimulation of the sole.
3. Leg Abduction Reflex: Involves the movement of the legs away from the midline of the body.
4. Tonic Labyrinthine Reflex (TLR): Involves changes in muscle tone in response to the position of the head, impacting the entire body.
