Which muscle inserts on the hyoid bone?

Which muscle inserts on the hyoid bone?

The digastric muscle passes through this opening as we’ll see. The stylohyoid arises from the lateral aspect of the styloid process. It’s inserted on the base of the greater horn of the hyoid bone.

Which nerves innervate the muscles of the hyoid apparatus?

The hypoglossal nerve innervates it, and its action is thought to move the hyoid bone rostrally.

Which of the following muscles does not directly attach to the hyoid?

The sternothyroid muscle originates from the dorsal surface of the manubrium and inserts on the oblique line of thyroid cartilage. That is why the sternothyroid is the only hyoid muscle that does not directly attach to the hyoid bone.

What muscles are attached to the hyoid bone quizlet?

Sternothyroid, sternohyoid, omohyoid, thyrohyoid.

Which are the infrahyoid muscles?

The four infrahyoid muscles are the sternohyoid, omohyoid, sternothyroid, and thyrohyoid muscles.

What are the 4 infrahyoid muscles?

infrahyoid muscles

• sternohyoid muscle.
• sternothyroid muscle.
• thyrohyoid muscle.
• omohyoid muscle.

What muscles depress the hyoid?

Infrahyoid muscles: Together, the infrahyoid muscles play an active role in swallowing through the movement of the larynx. The omohyoid, sternohyoid, and thyrohyoid act to depress the hyoid bone. The thyrohyoid elevates the larynx whereas the sternothyroid depress the larynx.

Which muscle attaches to the hyoid bone and retracts the tongue?

The hyoglossus muscle runs lateral to the genioglossus, arising from the greater cornu and anterior body of the hyoid bone and inserting in the lateral tongue between the styloglossus and palatoglossus laterally, and the inferior longitudinal muscle medially. It depresses and retracts the tongue.

What muscle is responsible for flexing the forearm?

biceps brachii
The biceps brachii, brachialis, and brachioradialis flex the forearm. The two-headed biceps brachii crosses the shoulder and elbow joints to flex the forearm, also taking part in supinating the forearm at the radioulnar joints and flexing the arm at the shoulder joint.

What are Prelaryngeal muscles?

The prelaryngeal musculature is divided in the midline from the hyoid bone to tracheostomy site and the anterior aspect the thyroid and cricoid cartilage dissected. The dissection at the posterolateral aspect of thyroid cartilage is minimal at this point (Figure 2).

What is the main function of the infrahyoid muscles?

Where is the transversus abdominis muscle located?

Transversus abdominis muscle (Musculus transversus abdominis) The t ransversus abdominis is a broad paired muscular sheet found on the lateral sides of the abdominal wall. Along with the external abdominal oblique and the internal abdominal oblique, it comprises the lateral abdominal muscles.

What are the characteristics of the transversus abdominis?

Transversus abdominis muscle 1 Origin and insertion. From their origin points, the transversus abdominis fibers course horizontally over the lateral abdominal wall towards the midline, oriented perpendicular to the linea alba. 2 Relations. 3 Innervation. 4 Blood supply. 5 Function.

What is the suprahyoid muscle?

The Suprahyoid Muscles. The suprahyoid muscles are a group of four muscles, located superiorly to the hyoid bone of the neck. They all act to elevate the hyoid bone – an action involved in swallowing.

What is the transversus abdominis aponeurosis?

The transversus abdominis aponeurosis makes up the posterior wall of the rectus sheath which covers the posterior upper three quarters of rectus abdominis, together with the aponeurosis of the internal abdominal oblique muscle.
