NS contains cells: neurons and neuroglia. Neurons transfer and process info. Neuroglia isolate neurons, provide framework, maintain intracellular environment, act as phagocytes
Neuron or nerve
Neuron. Neuron has a cell body, or soma
Neuron. Region around nucleus is perikaryon
Neuron. Cell body has branching dendrites
Neuron. Dendrites. Each branch has fine processes, dendritic spines, receive info from other neurons
Neuron. Dendrites. Dendritic spines. These spines are 80-90 percent of neuron surface area
Neuron. Cell body attached to elongated axon or nerve fiber ending at terminals
Neuron. Axon. Neuron communicates with another cell at axon terminals
Nervous tissue contains approximately 100 billionneuroglia or glial cells, five times number of neurons
Neuroglia smaller than neurons, unlike neurons they can divide
What are the two distinct cell types found within nervous tissue?
Neurons and neuroglia
Which of the two cell types found within nervous tissue has retained the ability to divide?
