INSECT NERVOUS SYSTEM

De-centralized

= behavior is integrated and controlled by segmental ganglia (dense cluster of interconnected neurons that process sensory information or control motor outputs; nerve cell bundle) instead of the brain

ganglia (ganglion)

Nerve cells are typically found grouped in bundles called _____________

nerve

is simply a bundle of dendrites or axons that serve the same part of the body

neurons

generate electrical impulses (action potentials) that travel as waves of depolarization along the cell’s membrane

action potentials

The neurons generate electrical impulses (_________________) that travel as waves of depolarization along the cell’s membrane

SOMA / nerve cell body

where the nucleus is found

DENDRITES

filamentous arborescent (branching) process, conduct impulses toward the cell body

AXONS

axis-cylinder process of a nerve cell, usually carry impulses away from cells

COLLATERALS

a part connected with or derived from a main branch
