Study Notes
Nervous Tissue Overview
- Composed of specialized nerve cells known as neurons.
- Accompanied by neuroglial cells, which support neurons and ensure proper nervous system physiology.
Function of Nerve Cells
- Generate neuroglial cells.
- Conduct electrical signals essential for communication within the nervous system.
Role of Neuroglial Cells
- Provide structural support by binding neurons together.
- Perform diverse functions crucial for the normal operation of the nervous system.
- Unlike neurons, they do not conduct nerve impulses.
Neuron Structure
- Comprised of three main parts:
- Cell Body: Contains the nucleus, serving as the metabolic center.
- Dendrites: Highly branched extensions that receive signals from other neurons or receptor cells.
- Axon: A singular extension responsible for transmitting nerve impulses away from the cell body to other neurons or effector cells; can be several feet long.
Locations of Nervous Tissue
- Predominantly found in:
- Brain
- Spinal cord
- Nerves
Importance of the Cell Body
- Central location for the nucleus.
- Acts as the metabolic hub for the neuron, facilitating necessary biological processes.
