Study Notes
Neuron Structure
- The cell body of a neuron, also known as perikaryon or soma, contains the nucleus and cytoplasm.
- The cell structure, including the cell body and cell processes (axon and dendrites), is considered the structural and functional unit of the nervous tissue.
Types of Nerve Cells
- Unipolar nerve cells have one short process that soon divides into two processes, central and peripheral.
- Multipolar nerve cells have multiple dendrites and one axon.
Neurotransmitter Transport
- Kinesin and dynein proteins are responsible for transporting neurotransmitters synthesized in the cell body to the axon terminals.
- Mutation in kinesin might be a target for motor neuron diseases related to transporting neurotransmitters.
Nervous Tissue
- The nervous tissue is anatomically divided into the central nervous system (brain and spinal cord) and peripheral nervous system (nerves and their associated ganglia).
- The nervous tissue is histologically formed by nerve cells and glial cells.
Alzheimer's Disease
- A prominent feature of Alzheimer's disease is the disintegration of microtubules, which is related to the breakdown of the cytoskeleton.
- Well-developed microtubules and intermediate filaments in the cell body are responsible for maintaining the structural integrity of neurons.
