Anatomy slings refer to specific groups of muscles and connective tissues that work together to produce and control movement, particularly dynamic and cross-body actions. These slings are especially relevant in sports medicine and physical therapy as they highlight how different parts of the body cooperate to maintain stability and facilitate movement.
Key Anatomy Slings
Anterior Oblique Sling
Primitive Reflexes: Asymmetrical Tonic Neck Reflex (ATNR),, Rooting Reflex
- Movement Patterns: Rotation of the head to one side, causing extension of the arm and leg on that side and flexion of the opposite arm and leg
- Movement Patterns: Turning the head towards a stimulus near the mouth, involving facial and neck muscles
- Components: Latissimus dorsi, thoracolumbar
fascia, multifidus, and contralateral gluteus maximus
- Function: Facilitates powerful extension
and rotational movements, stabilizing the pelvis and lower back
- Primitive Reflexes:
- Spinal Galant Reflex
- Movement Patterns: Stimulation of the skin along
the side of the spine, causing lateral flexion of the trunk
- Moro Reflex
- Movement Patterns: Sudden extension and then
flexion of the arms and legs in response to a perceived threat
- TCM Channels:
- Tai Yang Channels (Bladder)
- Bladder Sinew Channel
- Small Intestine Sinew Channel

- Components: Latissimus dorsi,
thoracolumbar fascia, and contralateral gluteus maximus
- Function: Facilitates powerful extension
and rotational movements, stabilizing the pelvis and lower back.
Lateral Sling
- Components: Gluteus medius, gluteus
minimus, tensor fasciae latae, and ipsilateral adductors
- Function: Supports lateral stability,
particularly during single-leg stance and side-to-side movements
- Primitive Reflexes:
- Asymmetrical Tonic Neck Reflex
(ATNR)
- Movement Patterns: Rotation of the head to one
side, causing extension of the arm and leg on that side and flexion of
the opposite arm and leg
- Landau Reflex
- Movement Patterns: Extension of the head, trunk, and legs when
held in a horizontal position
- TCM Channels:
- Shao Yang Channels (Gall
Bladder)
- Gall Bladder Sinew Channel
- San Jiao (Triple Burner) Sinew
Channel
Deep Longitudinal Sling
- Components: Erector spinae, multifidus,
sacrotuberous ligament, biceps femoris, and peroneus longus
- Function: Provides support for upright
posture and aids in forward propulsion during walking and running
- Primitive Reflexes:
- Tonic Labyrinthine Reflex (TLR)
- Movement Patterns: Changes in muscle tone in
response to head position changes relative to gravity, involving
postural adjustments
- Palmar Grasp Reflex
- Movement Patterns: Flexion of the fingers when
the palm is stimulated
- TCM Channels:
- Tai Yin Channels (Lung, Spleen)
- Lung Sinew Channel
- Spleen Sinew Channel
- Shao Yin Channels (Heart,
Kidney)
- Heart Sinew Channel
- Kidney Sinew Channel
Coordination of Sinew Channels in TCM
In TCM, the sinew
channels (tendinomuscular meridians) describe pathways of connective tissue,
muscles, and tendons that facilitate movement and maintain structural
integrity. When considering the coordination of movement, sinew channels can be
understood similarly to anatomy slings, as they describe how different parts of
the body work together.
- Cross-Body Movements:
- Anatomy Slings: Anterior and Posterior Oblique
Slings work across the body to facilitate rotational and stabilizing
movements.
- Sinew Channels: Channels such as the Yang Ming
(Stomach) and Tai Yang (Bladder) integrate to support rotational actions
and stability.
- Top-Bottom Movements:
- Anatomy Slings: Deep Longitudinal Sling
supports vertical stability and forward propulsion.
- Sinew Channels: The Deep Front Line (DFL) and
corresponding Tai Yin and Shao Yin channels (Lung, Spleen, Heart, Kidney)
support core stabilization and balance.
TCM Channels and Corresponding Anatomy
Slings
- Yang Ming Channels (Stomach) and Superficial Front Line (SFL): Facilitate flexion and forward movements.
- Tai Yang Channels (Bladder) and
Superficial Back Line (SBL): Support extension and upright posture.
- Shao Yang Channels (Gall Bladder)
and Lateral Line (LL): Aid in lateral and rotational stability.
- Jue Yin Channels (Pericardium and
Liver) and Spiral Line (SL): Integrate spiral and rotational movements for overall stability.
Anatomy slings
describe the functional cooperation of muscles and fascia to coordinate complex
movements, much like how sinew channels in TCM describe interconnected pathways
facilitating movement and structural integrity. Both systems highlight the importance
of cross-body and top-bottom interactions for maintaining stability and
facilitating dynamic actions. This understanding bridges traditional Chinese
medicine concepts with modern anatomical insights, providing a comprehensive
framework for movement and therapy.
