Sectional Anatomy

Generally, muscles overlie the bone that they move.

The largest vessels in the region of the neck are usually the internal jugular veins.

The last laryngeal cartilage encountered on a series of axial CT images of the neck, arranged in descending order, is the cuneiform.

The muscle seen most anteriorly on axial CT images of the neck is the platysma.

One of the divided origins of a muscle is termed a head.

The laryngeal cartilage associated with the bifurcation of the pharynx into the trachea and esophagus is known as the cricoid.

The trachea is approximately 20 in. (50.8 cm.) long.

Contrast is administered when acquiring axial CT images of the neck for localization purposes, not to obtain diagnostic information about the vessels.

The trachea is approximately 10 in. (25.4 cm.) long.

The thyroid cartilage is seen at the level of the inferior mandible.

The insertion of a muscle is fixed.

Generally, the origin of a muscle is distal.

The first laryngeal cartilage encountered on a series of axial CT images of the neck, arranged in descending order, is the epiglottis.

Nine pieces of cartilage make up the larynx.

The largest vessels in the neck are usually the external jugular veins.

The portion of the larynx seen on axial CT images that completely encircles the laryngopharynx is the thyroid.

The outermost covering of an entire muscle is the

The larynx is approximately 1.5 in. (3.81 cm.) long.

The glands found lateral to the hyoid bone on axial CT images of the neck are the sublinguals.

The larynx is approximately 4 in. (10.16 cm.) long.
