Thyrohyoid muscle - Made simple

Описание: Thyrohyoid muscle-Made simple
Thyrohyoid = Thyroid to Hyoid | C1 via XII | Elevates larynx.


Topics covered:
Introduction to infrahyoid (strap) muscles
Location and identification of thyrohyoid
Origin and insertion (attachments made simple)
Relations with sternohyoid & sternothyroid
Nerve supply – C1 via hypoglossal nerve
Actions explained with functional logic
Role in swallowing & phonation
Unique features & exceptions
Clinical correlations


Key Concepts :
🔹Deepest infrahyoid muscle
🔹Continuation of sternothyroid
🔹Thyroid cartilage → Hyoid bone connection
🔹Elevates larynx during deglutition
🔹 Only strap muscle supplied by C1 fibers via hypoglossal nerve
