Reactive, or postprandial, hypoglycemia: The pancreas produces too much insulin after a meal. Tumors: Tumors in parts of the body other than the pancreas can cause hypoglycemia. This is very rare. Severe illness: During times of critical illness, many different organs can be affected, including the pancreas. This can lead to hypoglycemia. Diagnosis
The inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system. The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph). The Organ of Corti is the sensory receptor inside the cochlea which holds the hair cells, the nerve receptors for hearing. The mechanical energy from movement of the middle ear bones pushes in a membrane (the oval window) in the cochlea. This force moves the cochlea's fluids that, in turn, stimulate tiny hair cells.
The middle ear is an air-filled cavity about the size of a pea. It turns sound waves into vibrations and delivers them to the inner ear. The middle ear is separated from the outer ear by the eardrum, or tympanic membrane, a thin, cone-shaped piece of tissue stretched tight across the ear canal.
