Description
Magnified more than 2500 times and fully three-dimensional, this neuron model is depicted in its natural setting. With the membranous envelope cut away, the cytological ultrastructure, organelles and inclusions within the cell body are depicted in contrasting colors.
A section of the axon lifts off to expose the enveloping myelin sheath and neuro-lemma, as well as the Schwann cell that formed them. Dendrites of the neuron extend into the background, and synaptic vesicles carrying neurotransmitters can be seen via a cutaway view. 54 features are identified in an illustrated key.
- Nucleus
- Nucleolus
- Cytoplasm
- Lysosome
- Vesicles (emerge from Golgi & ER)
- Golgi apparatus of Golgi complex
- Mitochondria
- Endoplasmic reticulum (ER) Nissl body (rough ER has polyribosomes on it)
- Nerve bers
- Axon hillock (cone-shaped base of axon)
- Axon
- Dendrite
- Schwann cell cytoplasm
- Node of Ranvier
- Cytoplasm of axon (axoplasm) includes: neuro laments, microtubules, vesicles and mitochondria
- Axolemma
- Schwann cell nucleus
