What does the omohyoid muscle attach to?

| Origin | Inferior belly: superior border of scapula near the suprascapular notch Superior belly: intermediate tendon |
|---|---|
| Insertion | Inferior belly: intermediate tendon Superior belly: body of hyoid bone |
| Action | Depresses and retracts hyoid and larynx Tenses carotid sheath |
Where does the omohyoid connect?
The omohyoid muscle is proximally attached to the scapula and distally attached to the hyoid bone, stabilising it. Its superior belly serves as the most lateral member of the infrahyoid muscles, located lateral to both the sternothyroid muscles and the thyrohyoid muscles.
What does the omohyoid do?
The main function of the omohyoid muscle is to depress or lower the hyoid bone, as well as the larynx. This depression of the hyoid bone and larynx occurs when a person speaks and at the end part of a swallow.
Does omohyoid attach to clavicle?
The Omohyoid attaches from the scapula to the clavicle to the hyoid bone.
Is the omohyoid muscle a laryngeal depressor?
The depressors of the larynx are the sternohyoid, sternothyroid, omohyoid, and are collectively known as the “strap”, or “infrahyoid”, muscles. This group of muscles receives innervation from C1-C3. The elevators of the larynx are the geniohyoid, digastric, thyrohyoid, mylohyoid, and stylohyoid muscles.
Does the omohyoid attach to the clavicle?
What is the function of the omohyoid and sternohyoid muscles?
This group of muscles contains four main muscles: the omohyoid muscle, the sternohyoid muscle, the sternothyroid muscle, and the thyrohyoid muscle. The primary function of this group of muscles is to depress the hyoid bone during speech and swallowing.
Does omohyoid elevate the hyoid bone?
These muscles attach to the superior aspect of the hyoid bone, and their main combined function is to elevate the hyoid and larynx and move them superiorly and anteriorly. The thyrohyoid, sternohyoid, sternothyroid, and omohyoid muscles, also referred to as strap muscles, are part of the infrahyoid musculature.
How do you release omohyoid muscle?
Gently bring your left ear towards your left shoulder. Once you reach your full range of motion, hold this position for 30 to 45 seconds. Slowly release the stretch, bringing your head upright. Repeat on the opposite side to stretch the left omohyoid muscle.
Why does my omohyoid hurt?
Injury to the omohyoid muscle is particularly common among bodybuilders and those involved in weight bearing exercise. Pain is often referred to the omohyoid when there is damage to the surrounding structures such as neck whiplash injury following an automotive accident.
Is omohyoid a strap muscle?
Gross anatomy There are four strap muscles: thyrohyoid: deep and lateral. omohyoid: superficial and lateral. sternohyoid: superficial and medial.
Why is it called strap muscles?
History and etymology The name “strap muscles” comes from their long and flat shape, similar to a belt or strap 3.
Which is the smallest cartilage in larynx?
