The skull is a bony skeleton, consisting of 23 bones.It protects the brain from various injuries.This frame has a 7 and 8 unpaired paired bones.

structure of the human skull

The structure of the skull are two main department - the brain and face.Human skull Departments affect virtually the entire body as they perform several functions.The facial skull department affects digestion, breathing and sensory organs.This department consists of unpaired (lower jaw, vomer, ethmoid and the hyoid bone) and doubles (nasal, lacrimal, palatine and zygomatic bones, the lower turbinate, upper jaw) bone.

unpaired bones of the skull have areas that are filled with air.By air cavity anatomists include maxilla, temporal, frontal, wedge-shaped, grid and steam bones.Upper flat bones of the skull.They consist of plates having bone substance, in which the cells are blood vessels and bone marrow.

Brain human skull is composed

of paired (temporal and parietal) and unpaired (frontal and sphenoid occipital) bone.This unit is considered to be a framework that protects the brain.It is located on the facial region.The parietal bones form the arches and occipital bone forms the base of the skull.Pneumatic temporal bone forms the cranial vault, as well as the capacity of the organs of hearing.Pneumatic frontal bone has a bow and two scales.With regard to pneumatic sphenoid, it consists of a body having the pituitary gland, located in the pituitary fossa.

human skull bones are connected by joints.

skull features

human skull bone is a complex organ that performs the following functions:

  • Serves strong framework for the senses and the brain.
  • His bones connect chewing, facial and neck muscles.
  • Participates in digestion.
  • takes part in the process of formation of speech and sounds.

Injury

skull skull injuries are serious pathological conditions that can lead to serious violations of the human organism: disruption of memory and speech, mental disorders, paralysis.The most common injuries of the skull are considered:

  • Traumatic brain injury.
  • fracture of the skull base.
  • Fracture vault open and closed.

fracture of the cranial vault is accompanied by respiratory failure and loss of memory.This change manifests itself in the form of hematoma scalp.A person with such an injury must be put on a flat surface and put a bandage on his head.If the person is unconscious, it must be put on a stretcher and into one side of the body to put a cushion or pillow.In case of violation of breathing performed artificial respiration, then the patient is urgently taken to the hospital for medical examination.

If we talk about the turn of the base of the skull, it is characterized by headache, dizziness, loss of consciousness and bleeding from the ears and nose.In such a situation, you should immediately release the oral cavity and respiratory tract from the blood and cerebrospinal fluid.In case of violation of breathing is necessary to carry out artificial respiration.

Traumatic brain injury leading to brain concussion.It is accompanied by headache, dizziness, loss of consciousness, rapid heart rate, nausea, vomiting, general weakness, paleness of the face, as well as a violation of the respiratory and cardiovascular systems.This patient is an urgent need to do artificial respiration and chest compressions.In addition, the surface of the wound bandage should be immediately followed by hospitalization implement.

As for intracranial structures, they require a craniotomy.Craniotomy is a surgical operation to form a hole in the skull.The main objective of craniotomy - to achieve the injured area in which there is a hematoma or other neoplasms.
