Lecture Notes: Platysma Muscle and Its Importance

Introduction

  • Discussion of platysma muscle, often overlooked.
  • Importance of maintaining stability in the cervical spine and head/neck.
  • Interconnectedness of body parts.

Anatomy and Function of the Platysma Muscle

  • Located below the collarbone, runs along the side of the neck, attaches under the jawline.
  • Involved in facial expressions, such as frowning and jaw movements.
  • Innervated by the facial nerve (cranial nerve VII).

Importance of the Platysma Muscle

  • Aids in stabilizing the head and neck.
  • Dysfunction can lead to pain, often experienced after whiplash, concussions, etc.
  • Working the platysma can improve the parasympathetic nervous system, aiding relaxation and reducing 'fight or flight' mode.

Autonomic Nervous System Overview

  • Two parts: Sympathetic (fight or flight) and Parasympathetic (rest and digest).
  • Cannot operate simultaneously.
  • Importance of cranial nerves, especially facial nerve (VII) for stimulating parasympathetic system.

Connection to Other Systems

  • Effects of head posture on body mechanics and respiratory function.
  • Forward head posture increases stress on spine.
  • Platysma exercises can aid in correcting posture, improving breathing.

Platysma Muscle Exercises

Basic Exercise

  • Move chin towards collarbone and lift chin upward.
  • Engage the platysma by frowning and moving jaw.
  • Perform 3-5 repetitions.

Advanced Exercise

  • Chin movements combined with jaw deviations.
  • Caution advised, especially with TMJ issues.

Importance of Head Position

  • Forward head posture can lead to increased stress and potential pain.
  • Correct head alignment improves overall body function.

Additional Tips

  • Engage with exercises slowly; avoid pain.
  • Community and laughter enhance healing.
  • Persistent exercise over a month may show significant improvements.

Closing Remarks

  • Importance of educating oneself to overcome chronic pain.
