Study Notes
Nervous System Cells
- Neurons are considered the structural and functional unit of the nervous system.
Types of Neurons
- Motor neurons convey impulses from the central nervous system (CNS) or ganglia to effector cells.
Supporting Cells
- Glial cells are the supporting cells of the nervous tissue that provide insulation to axons.
Integration and Communication
- Interneurons form a communicating and integrating network between sensory and motor neurons.
Neuron Function
- Dendrites are the processes that convey impulses toward the neuron's cell body.
