Posterior Triangle Of Neck | Anatomy | MBBS 1st Year Anatomy | INICET/FMGE/NEET PG | Dr. Pradeep Pawar Sir Check Out the PW MedEd One Plan: https://meded.onelink.me/5aR9/ogdp7ihj One Shot Series Annotated Notes: https://t.me/neet_pg_notes_by_meded In this high-yield Anatomy one-shot session, Dr. Pradeep Pawar Sir decodes the Posterior Triangle of the Neck. This is a critical topic for MBBS 1st-year professional exams and a favorite for examiners in NEET PG, INICET, and FMGE. Understanding the boundaries, floor, and neurovascular contents of this region is essential for clinical practice and surgical safety. Dr. Pradeep Pawar Sir simplifies the complex muscular floor and the subdivisions created by the Omohyoid muscle. The lecture places a strong emphasis on clinical correlation, particularly the Spinal Accessory Nerve (CN XI). You will learn why a lymph node biopsy in the neck can lead to the inability to shrug shoulders or perform overhead abduction, and why the Sternocleidomastoid remains intact even when the nerve is damaged within the triangle. Key Concepts Covered: Boundaries & Subdivisions: Sternocleidomastoid, Trapezius, and Clavicle; Occipital and Supraclavicular triangles. The Floor: Detailed study of muscles from above downwards (Semispinalis capitis to Scalenus medius). The Fascia: Role of the Prevertebral layer of deep cervical fascia. High-Yield Contents: Brachial plexus, 3rd part of Subclavian artery, Spinal accessory nerve, and Cervical plexus branches. Clinical Anatomy: Nerve injuries during cervical biopsies, Trapezius paralysis, and "shrugging" test.
