Explains proprioception as the sense of body-part position, movement and spatial orientation, and why it matters for balance and coordination. Notes its links with the motor system and with vision and touch. Lists two pathways: the dorsal column–medial lemniscus route, and the main sensory trigeminal pathway from the face, traced through its neurons from ganglion to cortex.

SYSTEM FOR PROPRIOCEPTION
Proprioception, often refferred to as the "six sense", is the ability to sense the position, movement, and sapital orientation of on's body part.
This sensory information is crucial for maintaining balance, coording movements.
The proprioceptive system involves several componants and pathways.
Proprioception is closely linked to the motor system, influencing motor planning, execution & coordination.
Proprioception is integrated with information from other sensory modalities, such as vision and touch, to provide a comprehensive understanding of oné's body in the environment
Pathways:
1. Dorsal column - medial lemniscus (DC-ML) (explained in 149)
↳ from the body.
2. Main Sensory trigeminal pathway: (from the face)
1° trigeminal ganglion → 2° main sensory trigeminal nucleus (in the pons) → X trigeminal lemniscus → 3° VPLN in the thalamus → 1° sensory cortex.
