Muscle is a contractile form of tissue which animals use to effect movement. Muscle  are largely made up of actin and myosin filaments.

Vertebrae refers to any of the small bones which make up the backbone.

Larynx is an organ of the neck of mammals involved in breath control, protection of the trachea and sound production, housing the vocal cords, and that is situated at the point where the upper tract splits into the trachea and the oesophagus/esophagus.

A trachea is a thin-walled, cartilaginous tube connecting the larynx to the bronchi; the windpipe.

The Longus colli muscle (commonly referred to as the long muscle of the neck) is a muscle on anterior surface of the cervical vertebrae.

Infrahyoid position is one that is below the hyoid bone in the neck; applied to a group of four pairs of muscles in the anterior part of the neck.

The position of the longus coli muscles is on the anterior surface of the cervical vertebrae, while the infrahyoid muscles lie on the anterior surface of the larynx and trachea.
