The traditional darkroom processing sequence for radiographs is as follows:

1. Developing: This step involves immersing the film in a developing solution to reveal the latent image captured on the film.
2. Rinsing: This step is crucial to halt the development process, preventing further exposure to the chemical in the developer.
3. Fixing: The film is then placed in the fixer solution to stabilize the image and make it insensitive to light.
4. Washing: The film must be washed to remove any residual chemicals before drying.
5. Drying: Finally, the film is dried for use.

White sponge nevus is inherited as an autosomal dominant trait.

The chemical compound acetylcholine (ACh) is a neurotransmitter in both the peripheral nervous system (PNS)and central nervous system (CNS) in many organisms including humans. Acetylcholine is one of many neurotransmitters in the autonomic nervous system (ANS) and the only neurotransmiter used in the somatic nervous system. 

Constitutional delay of growth is characterized by a positive family history of late maturation, while growth hormone deficiency typically is not associated with such a family pattern.

Prions are infectious agents composed solely of protein. They do not have nucleic acids like DNA or RNA and are responsible for several neurodegenerative diseases. The primary reservoir for prions is thus the proteinaceous particles themselves.
