Sternocleidomastoid Muscle | Anatomy, Relations, Nerve Supply & Clinical Importance

In this detailed anatomy lecture, we study the Sternocleidomastoid Muscle (SCM) — one of the most important muscles of the neck and a key landmark in head and neck surgery. This video covers: • Why SCM is clinically important • Boundaries of the posterior triangle • Demonstration of SCM on self (clinical examination) • Parts of sternocleidomastoid muscle • Developmental aspect and its relation to spinal accessory nerve • Arterial supply and detailed nerve supply • Unilateral and bilateral actions (tabular format) • Relations of SCM – superficial and deep • External carotid artery and its branches • Deep cervical lymph nodes (upper, middle, lower lateral groups) • Clinical anatomy – torticollis, branchial cyst, branchial fistula, clavicle fracture, SCM flaps • Important MCQs for exam preparation This lecture is especially useful for MBBS, BDS, BPTh, BAMS, BHMA students, NEET PG aspirants, postgraduate surgical students, and anyone preparing short notes on the Sternocleidomastoid muscle. Learn anatomy in a clinically integrated and exam-oriented manner.
