What muscles border the anterior triangle of the neck?

What is your Sternocleidomastoid?

Sternocleidomastoid is the most superficial and largest muscle in the front portion of the neck. It is also known as SCM or Sternomastoid or Sterno muscle. The name has the origin of the Latin words: sternon = chest; cleido=clavicle and the Greek words: mastos= breast and eidos=shape, form.

Laterally, the anterior triangle is bounded by the anterior border of the sternocleidomastoid muscle.

What are the borders of the occipital triangle?

Boundaries

• anterior: posterior border of sternocleidomastoid.
• posterior: anterior border of trapezius.
• inferior: inferior belly of omohyoid.

What is palpated in the anterior triangle of the neck?

In the anterior neck, you can palpate the cartilages of the larynx and trachea. The thyroid gland is closely associated with the cricoid cartilage and the tracheal rings and should always be palpated in a general physical examination of the neck.
