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.
