Bone hyoid bone

Bone hyoid bone: A piece called the body located in the middle and has a pair of small horns lesser cornu, and a pair of horns large grater cornu. A thin bone in the neck breaks when strangulation. There ligament stylohyoid ligament bone mamillary styloid process to younger this century bone Middle constrictor muscle arises from the lower part of this bond + century younger + and the upper edge of the biggest century.
Muscle Tltkien from behind in the median line. Lower fibers cover the reduced muscle fiber lower inferior constrictor Supreme fibers covering part of the reduced muscle Supreme superior constrictor Any such three cups put one in the other.
Lower the reduced muscle inferior constrictor slash arise from the thyroid cartilage thyroid cartilage It cartilage cricoid cartilage Lower fibers are cross-sectional (the offer) and called cricopharyngeus
Lower the reduced muscle between transverse fibers and fibers that ascend to the top there is a weak area, such as vacuum named Killian's dehiscence is a poor place possible to come out of it is part of the dinner mucous that causes pharyngeal diverticulum, which is possible to press on the outside of the pharynx causing difficulty in swallowing. The beginning of the esophagus also be narrowed area....


Infrahyoid muscles:
Also called strap muscles, which is part of a group of muscles located in the front of the body and be a long strip, for example muscle rectus abdominis muscle
These muscles in the neck are: Arbahazoaj of the muscles and the meaning of its name it's located under Atm hyoid bone in the neck:

sternothyroid origin: sternum and stick thyroid cartilage
thyrohyoid origin: sternum and stick hyoid bone
sternohyoid origin: thyroid cartilage and hyoid bone stick
omohyoid origin: superior border of scapula and stick hyoid bone

Nerve provider of these muscles is: ansa cervicalis of neural network cervical cervical plexus C1-3 except thyrohyoid muscle they receive only the first spinal nerve C1.

Work these muscles:
Is that it proves the bone hyoid bone in order to work the muscles above the bone suprahyoid muscles.
Or that Tgerazm hyoid bone to the bottom is the larynx during speech and swallowing.

It is worth mentioning that this bone is inseparable any other bone so the medical students more often than they miss in the samples by studying bone is considered "pending" like scapula bone in the back that is to say it in place depends on the muscle-bound.
