🧠 Topics Covered:
Carotid Sheath: Explore the carotid sheath, a fibrous connective tissue structure in the neck that encloses the common carotid artery, internal carotid artery, internal jugular vein, and vagus nerve (CN X). Investigate its anatomical relationships and clinical significance in surgical approaches to the neck, as well as its role in protecting and providing support to the vital structures within.
Axillary Sheath: Delve into the axillary sheath, a fascial sleeve that surrounds the axillary vessels and brachial plexus as they traverse the axilla. Explore its anatomical boundaries, contents, and clinical implications in surgical procedures and traumatic injuries involving the axillary region. Understand its role in providing protection and facilitating the passage of neurovascular structures through the axilla.
Posterior Triangle of the Neck: Investigate the posterior triangle of the neck, a region bounded by the sternocleidomastoid muscle, trapezius muscle, and clavicle. Explore its anatomical contents, including the scalene muscles, brachial plexus, external jugular vein, and accessory nerve (CN XI), as well as its clinical relevance in surgical approaches, lymphatic drainage, and the diagnosis of cervical lymphadenopathy. Understand its importance in the context of head and neck anatomy and pathology.
