Osteonecrosis of the jaw fatty degeneration and/or necrosis, often with pooled fat from destroyed adipose cells (oil cysts) and with marrow fibrosis (reticular fatty degeneration)"" are seen. These changes are present even if ""most bony trabeculae appear at first glance viable, mature and otherwise normal, but closer inspection demonstrates focal loss of osteocytes and variable micro cracking (splitting along natural cleavage planes). The microscopic features are similar to those of ischaemic or aseptic osteonecrosis of long bones, corticosteroid-induced osteonecrosis, and the osteomyelitis of caisson (deep-sea diver's) disease"". In the cancellous portion of femoral head it is not uncommon to find trabeculae with apparently intact
Nerve tissue protein Nerve tissue protein Nerve tissue is a biological molecule related to the function and maintenance of normal nervous tissue. An example would include, for example, the generation of myelin which insulates and protects nerves. These are typically calcium-binding proteins. There are two types of myelin the first is ogliodendrocyte- Myelin which can be found in the mammalian Central Nervous System (CNS) and the second is Schwann cells which are found in the Peripheral Nervous System (PNS). Myelination of axons by these Schwann cells are essential for normal nerve function. Peripheral nerves rely on communication between axons and Schwaan cells. Prion
