Study Notes
Structural and Functional Units
- Neurons are the primary structural and functional units of the nervous system.
- Neuroglia, or glial cells, primarily serve supportive roles in nervous tissue.
Types of Neurons
- Afferent neurons carry information toward the central nervous system.
Neuron Anatomy
- The cell body of a neuron, known as the perikaryon, contains the nucleus and organelles.
- Nissl bodies, composed of rough endoplasmic reticulum, are basophilic cytoplasmic materials present in the cell bodies of neurons.
Cell Division and Supportive Cells
- Neurons typically do not divide due to the lack of centrioles, which are necessary for cell division.
- Schwann cells provide support for peripheral nerves, while oligodendrocytes support the central nervous system.
