Our gift of the gab is all due to a small horseshoe-shaped bone suspended in the muscles of our neck, like a piece of fruit trapped in Jell-O. The hyoid bone, which is the only bone in the body not connected to any other, is the foundation of speech and is found only in humans and Neanderthals.
5
Is the hyoid bone an irregular bone?
Irregular bones serve various purposes in the body, such as protection of nervous tissue (such as the vertebrae protect the spinal cord), affording multiple anchor points for skeletal muscle attachment (as with the sacrum), and maintaining pharynx and trachea support, and tongue attachment (such as the hyoid bone).
6
What is a hyoid bone fracture?

How many bones in your body when you are born?
Babies are born with about 300 bones, almost a third of which eventually fuse together to form the 206-bone skeleton of an adult. Further, some of the "bones" in a baby's body are not really bone at all, but instead cartilage, a soft and flexible material that eventually grows into a bone.

What is the only bone that doesn't have a joint?
9. One bone isn't connected to any other bones. The hyoid bone, which is in your throat, is the only bone that doesn't connect to a joint. The hyoid is responsible for holding your tongue in place.
12
What does the hyoid bone articulate with?
The hyoid bone is located between the chin and the thyroid cartilage. It is also at the base of the mandible, or lower jawbone. Unlike other bones within the skeleton, the hyoid does not feature any major points of articulation (joints) with other bones.
13
Is the hyoid bone axial or appendicular?
The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.
14
How many true ribs are in the human body?
In humans there are normally 12 pairs of ribs. The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs. The 8th, 9th, and 10th pairs—false ribs—do not join the sternum…

Which bones form the palm of your hand?
The carpals form many small gliding joints with each other to give extra flexibility to the wrist and hand. The five long, cylindrical metacarpals form the supporting bones of the palm of the hand.

18
What pierces the thyroid membrane?
The thinner, lateral (side) portions of the thyrohyoid membrane are pierced by the internal laryngeal artery and the internal laryngeal nerve, which is a branch of the superior laryngeal nerve. This nerve helps sense the presence of mucus in the larynx, or voice box, and is part of the coughing reflex.
19
What does the Sternohyoid do?
The sternohyoid muscle's main function is the depression of the hyoid bone. The hyoid bone is located below the mandible, or lower jaw, and is a 'U' shaped bone that is partially responsible for tongue movement and the action of swallowing. The sternohyoid is one of a pair of muscles responsible for this action.
