The Nervous System

Master the nervous system! Label neurons & match neuroglia functions with our science worksheet.

Neuron Labeling: Label this neuron by using the following terms: Axon, Dendrite, Cell body, Nucleus, Schwann cell, Node of Ranvier Axon Dendrite Cell body Nucleus Node of Ranvier Schwann cell Which of the following is NOT a function of the nervous system? Coordinating all body functions Responding to stimuli Maintaining homeostasis All of these are functions of the nervous system Neuroglia Matching: Match each type of neuroglia with its correct function below. Microglia Carries out phagocytosis of bacteria and other cell debris Oligodendrocyte Provides the insulating layers of myelin around axons Astrocyte Lies between neurons and blood vessels; regulates nutrient and ion concentrations within tissues Ependymal cell Forms an epithelial-like membrane that covers specialized brain parts and encloses spaces Which type of neuroglia cell helps to form scar tissue that fills in spaces of the CNS following an injury? Astrocyte Oligodendrocyte Ependymal cell Microglia Which type of neuron has two processes (one from each end) arising off the main cell body? Unipolar Bipolar Multipolar Motor Which type of neuron is found within specialized parts of the eyes, nose, and ears? Unipolar Multipolar Bipolar Motor What are specialized masses of unipolar neuron cell bodies that sit outside the brain and spinal cord? Action potentials Interneurons Nissl bodies Ganglia Neuron Matching: Match each part of a neuron with its correct function below. Dendrite Receives electrochemical messages Axon Sends information away from the neuron Cell body Contains the nucleus and Nissl bodies Neurilemma Cell membrane of a neuron Node of Ranvier Narrow gap in the myelin sheath between Schwann cells Schwann cell Composed of myelin and wound tightly around the axon; increases impulse speed Which type of neuron would stimulate muscles to contract or glands to secrete? Sensory Motor Interneuron On which type of axon is a nerve impulse the fastest? Myelinated Unmyelinated The two main types of cells in the nervous system are _ (the nerve cells) and _ (the supporting cells). neurons, neuroglia What are the components of the Central Nervous System and Peripheral Nervous System? Main Types of Nervous System Central Nervous System brain spinal cord Peripheral Nervous System nerves Label the functions of the Nervous System on this picture. Sensory Input Motor Output Integration Somatic Nervous System Autonomic Nervous System Voluntary Control Involuntary Control Skeletal Muscles Smooth Muscles and glands Which of the following statements about the neuron is FALSE? Neurons can live and function for a very long time. Neurons has a high metabolic rate which requires oxygen and glucose. Neurons undergo mitosis in order to divide.
