The olecranon bursa is a fluid filled sac-like structure that acts as a cushion, allowing the posterior skin of the elbow to glide past the olecranon process with minimal friction. 8 mm; proximal projection of olecranon process beyond proximal rim of semilunar notch, 0.
The nerve cell, being of an animal would contain various organelles, including the cell membrane,nucleus (which contains the nucleolus, the cytoplasm, mitochondria, lysosomes, â¦ cytoskeleton, chromatain Endoplasmic reticulum, Golgi Apparatus, and possibly flagella, cilia, centriols and ribosomes.
A neuron has many of the same organelles such as mitochondria, cytoplasm and a nucleus, as other cells in the body. 1  Nucleus-contains genetic material (chromosomes) including information for cell development and synthesis of proteins necessary for cell maintenance and survival.ells of the nervous system, called nerve cells or neurons, are specialized to carry messages through an electrochemical process. The human brain has approximately 100 billion neurons. To learn how neurons carry messages, read about the action potential.
