Image Scheme body cavities en.svg thumb 300px Human body cavities Ventral bodycavity is to the right The ventral bodycavity is a human bodycavity that is in the anterior front aspect of the human body . It is made up of the thoracic cavity , and the abdominopelvic cavity. The abdominopelvic cavity is further separated into the abdominal cavity and pelvic cavity , but there is no physical barrier between the two. The abdominal cavity contains digestive organs, the pelvic cavity contains the urinary bladder, internal reproductive organs, and rectum. There are two methods for dividing the abdominopelvic cavity. The clinical method, used by physicians and nurses, utilizes four sections called quadrants. They are the Right Upper Quadrant, the Left Upper Quadrant, the Right Lower Quadrant, and the Left Lower quadrant. The directional terms refer to the model s right and left, not the viewer s. Clinicians use the quadrant method because in reality, organs are mobile and move around when the patient is in different positions. The second method for dividing the abdominopelvic cavity is preferred by anatomists. This method divides the cavity into nine regions. The regions are the left and right hypochondriac regions, so named because they lie under the ribs the epigastric region which is approximately where the stomach is located between the hypochondriac regions the right and left lumbar regions which flank the umbilical region which surrounds the umbilicus, or belly button , the right ... lies between the hips.

It is directed laterally and forward and articulates with the head of the humerus it is broader below than above and its vertical diameter is the longest. This cavity forms the glenohumeral joint along with the humerus . This type of joint is classified as a synovial , ball and socket joint . The cavity surface is covered with cartilage in the fresh state and its margins, slightly raised, give attachment to a Fibrocartilage fibrocartilaginous structure, the glenoid labrum , which deepens the cavity. Compared to the acetabulum hip joint the glenoid cavity is relatively shallow. This makes the shoulder joint prone to luxation . Strong glenohumeral ligaments ligaments and muscle s prevents luxation in most cases. By being so shallow the glenoid cavity allows the glenohumeral joint to have the greatest mobility of all joints in the body, allowing 120 degrees of unassisted flexion .

An Electromagnetism electromagnetic cavity is a cavity that acts as a container for electromagnetic field s such as photon s, in effect containing their wave function inside. The size of the cavity determines the maximum photon wave length that can be trapped. Additionally, it produces quantized energy level s for trapped charged particles like electrons and protons . The earth s magnetic field in effect places the earth in an electromagnetic cavity. Physical description of electromagnetic cavities Electromagnetic cavities are represented by potential well s, also called boxes , which can be of limited or unlimited depth V sub 0 sub . Quantum mechanic boxes are described by the time independent Schr dinger equation div align center math left frac hbar 2 2m nabla 2 V mathbf r right psi mathbf r E psi mathbf r math div with the additional boundary condition s the wave function is confined to the box infinite deep potential well or approaches zero as the distance from the wall increases to infinity, thus normalisable the wave function must be continuous function continuous the derivative of the wave function must be continuous which leads to real solutions for the wave functions if the net energy of the particle is negative., i.e. if the particle is in a bound state . Applications of electromagnetic cavities Electrons which are trapped in an electromagnetic cavity are in a bound state and thus organise themselves as they do in a regular atom , thus expressing chemical like behaviour. Several researchers have proposed to develop programmable matter by varying the number of trapped electrons in those cavities. http www.wired.com wired archive 9.10 atoms.html The discrete energy levels of electromagnetic cavities are exploited to produce photons of desired frequencies and thus are essential for nano or submicrometre scale laser devices.
