Muscle Spindle Nuclear Bag Cell

Specialized intrafusal muscle fibers within the muscle spindle, characterized by a cluster of nuclei in a central 'bag' region, contributing to proprioception.

Key Functions:

• Detects changes in muscle length and rate of stretch.
• Innervated by both sensory and motor neurons.
• Essential for proprioception and motor control.

Interacting Systems & Components:

• Muscle Spindle (component of)
• Neuron (innervated by)
• Musculoskeletal System (part of)
• Nervous System (provides sensory feedback to)
