• Origin

Superior Oblique Portion: Anterior tubercles of transverse processes of C3–C5.

Vertical (Intermediate) Portion: Anterior surfaces of bodies of C5–T3.

Inferior Oblique Portion: Anterior surfaces of bodies of T1–T3.

• Insertion

Superior Oblique Portion: Anterior tubercle of the atlas (C1).

Vertical Portion: Anterior surfaces of bodies of C2–C4.

Inferior Oblique Portion: Transverse processes of C5–C6.

• Agonist(s)

- Longus capitis,

- Rectus capitis anterior,

- Sternocleidomastoid (in flexion),

- Scalenes (anterior and middle, in flexion).

• Antagonist(s)

- Cervical paraspinals (e.g., semispinalis cervicis, splenius cervicis),

- Upper trapezius (in extension),

- Levator scapulae.

• Function

Flexes the cervical vertebrae and neck.

Assists in lateral flexion and slight rotation.

Provides deep anterior cervical spine stability.

Crucial for postural support and coordination of head and neck movement.

TRIGGER POINT(S)

• Location

Trigger points are typically found deep within the anterior neck, along the anterior surfaces of the vertebral bodies from C2–T3.

Due to its depth, it is not easily palpable and is typically accessed through precise anterior cervical palpation by trained professionals.

• Pain Referral Pattern

Pain may present as deep, aching discomfort in the front of the neck or throat.

May mimic symptoms of a sore throat or difficulty swallowing.

Occasionally refers pain to the upper chest or anterior shoulder region.

Can contribute to feelings of cervical instability or weakness in head control.

💢

Potential Causes

• Whiplash injuries or hyperextension of the cervical spine.

• Poor posture, particularly with forward head and rounded shoulders.

• Weak deep neck flexors combined with overactive superficial neck muscles.

• Prolonged neck flexion (e.g., looking down at devices).

• Dysfunction of the deep cervical flexor system.

✅

Prevention Tips

• Strengthen deep neck flexors through targeted exercises like chin tucks.

• Maintain proper head and neck posture, especially during prolonged sitting.

• Limit excessive use of mobile devices in a head-forward position.

• Perform regular stretching and mobility exercises for the neck and upper thorax.

• Address breathing patterns—diaphragmatic breathing can reduce anterior neck overuse.

• Seek professional treatment after whiplash or neck trauma to restore function.
