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.
• Encouragement to subscribe and engage with the content for further learning.
