- May 6, 2026The superior belly connects the intermediate tendon to the hyoid bone. The ansa cervicalis innervates this belly, reflecting its infrahyoid…
- May 6, 2026The inferior belly runs from the scapula to the intermediate tendon, crossing the posterior triangle. The right angle between the…
- May 6, 2026The vertical part is the central and largest component of longus colli, providing pure cervical flexion. Its attachment to multiple…
- May 6, 2026The superior oblique fibres of longus colli connect the mid-cervical transverse processes to the atlas, producing ipsilateral upper cervical flexion-rotation.
- May 6, 2026The inferior oblique fibres connect the upper thoracic vertebral bodies to the lower cervical transverse processes, producing lower cervical rotation-extension.
- May 6, 2026The sternohyoid is the most superficial infrahyoid (strap) muscle, overlying the thyroid gland and larynx. It is routinely divided in…
- May 6, 2026The sternothyroid is the deeper strap muscle, attaching directly to the thyroid cartilage. It is the key muscle for laryngeal…
- May 6, 2026The thyrohyoid has the unique distinction of being innervated by C1 fibres that travel with the hypoglossal nerve (CN XII).…
