Study Notes
Proprioception
- Proprioception is mediated by mechanoreceptors, specifically proprioceptor neurons.
- Proprioceptors detect changes in joint angle, muscle length, and muscle tension, providing information about body position and movement.
- In the central nervous system, proprioceptive signals are integrated with sensory information from visual, vestibular, and auditory systems.
Motor Control
- Proprioceptive feedback plays a critical role in many animals, enabling them to make precise movements and maintaining posture.
- In vertebrates, limb movement and velocity are influenced by proprioceptive feedback, which helps to regulate motor control and prevent oscillations.
