Card Set Information
Contains granular cytoplasm, mitochondria, lysosomes, a golgi apparatus, and microtubles.
Fines threads that form a network that extend into the axon and supports it.
Nissl bodies, membrane packets scattered throughout the cytoplasm consisting mainly of rough endoplasmic reticulum.
Highly branched, provides receptive surfaces with which processes from other neurons communicate.
A cone-shaped thickening that the axon arises on from the cell body.
Branches off from axon.
Specialized ends of the fine extensions off of the axon.
Used by the axon terminal ends close to the receptive surface of another cell.
Tiny thorn-like spines on the surface of some dentrites used as contact points for other neurons.
When the axon conveys biochemicals produced in the neuron cell body which moves vesicles, mitochondria, ion, nutrients, and neurotransmitters to the ends of the axon.
Neuroglias (found in PNS) that encase the large axons of peripheral neurons in lipid-rich sheaths.
The myelin layer coating, made of lipids and proteins, that wraps around the axon.
Parts of Schwann cells that contain most of the cytoplasm and nuclei, found wrapped around outside the myelin sheath.
Narrow gaps in the myelin sheath between Schwann cells.
Nodes of Ranvier
Axons that lack a myelin sheath, but instead the axons lie partially or completely in a longitudinal groove of a Schwann cell.
Chromatophilic substances, membrane packets scattered throughout the cytoplasm.
