A cup of lead pellets and cup of feathers both occupy 8 fl. oz. of volume. The lead will weigh a lot more than 8 ounces on a scale. The feathers will weigh a lot less than 8 ounces on a scale. 500 grams of mini marshmallows = 10 cups. 500 grams of flour = 4 cups.
The layer of the epineurium that extends within the nerve to define the fascicles is termed the internal epineurium. Together, these two layers form the epineurium, which varies in thickness along the course of a nerve. The epineurium is usually most abundant around joints, as its function is to protect the nerves from stretching and subsequent injury.
Capillaries are only found in the endoneurium and function as an extension of the bloodbrain barrier. Sunderland Type 2 injuries occur only to the axon, whereas Type 3 and 4 damage the endoneurium and perineurium, respectively. The endoneurium, a loose connective tissue, is the fourth layer surrounding the neurites. The myelin and endoneurium left behind are phagocytized by cells involved in the inflammatory response.
