forms of Leprosy is nerve infection. Nerve damage appears to result from the multiplication of bacilli within Schwann cells and damage to the perineurium. Most of the deformities occurring from Leprosy are in fact due to trauma or a secondary infection. In a Leprosy infection one of the first symptoms are anesthesia to heat and cold. Leprosy affects the peripheral nervous system by attacking the myelin sheath surrounding the axons which affects the reliability and speed of nerve impulses. In other

The Structure of Inner Ear The inner ear is the essential part of the organ of hearing‚ receiving the ultimate distribution of the auditory nerve. It also called the labyrinth. Inner ear consists of two parts: the osseous labyrinth‚ a series of cavities within the petrous part of the temporal bone‚ and the membranous labyrinth‚ a series of communicating membranous sacs and ducts‚ contained within the bony cavities. The osseous (or bony) labyrinth: Bony labyrinth is the rigid outer wall of

consists of the brain‚ spinal cord‚ nerves‚ ganglia‚ and parts of the receptor and effector organs. Your nervous system is composed of the central nervous system‚ the cranial nerves‚ and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves that branch from the cervical‚ thoracic‚ lumbar‚ and sacral regions of the spinal cord are called the peripheral nerves.
