Lecture Test 3

Regions where there are gaps in the myelin sheath (2 words)

Neurofibril nodes

Store neurotransmitters within axon terminal (2 words)

Synaptic vesicles

Sends signals away from cell body

Axon

Structural classification of somatic sensory neurons

Unipolar

Chemical released by a neuron to stimulate another cell

Neurotransmitter

Neuron that sends a signal to another neuron

Presynaptic

Phagocytic cells within the CNS

Microglia

Connective tissue that bundles axons into fascicles

Perineurium

Thousands of interneurons concerned with a particular function (2 words)

Neural pool

Connective tissue that surrounds an axon and its neurolemmocytes

Endoneurium

Dense connective tissue thst bundles fascicles into a nerve

Epineurium

Effector for somatic nervous system (2 words)

Skeletal muscle

Part of neuron that receives, integrates and sends nerve impulses

Soma

Surround neuronal cell bodies within ganglia (2 words)

Satellite cells

Structural classification of motor neurons

Multipolar

Specialized junction between a neuron and any other cell

Synapse

Receive and send input towards cell body for processing

Dendrites

Form myelin sheath in CNS

Oligodendrocytes

Neurons found entirely within CNS that connect neurons in circuits or pathways

Interneurons

Concentric layers of membrane that insulate regions of an axon (2 words)

Myelin sheath

Interconnections between many neurons (2 words)

Neural circuit

Type of conduction that occurs in myelinated fibers

Saltatory

Structural classification of neurons associated with special senses

Bipolar

Neuron that receives a signal from another neuron

Postsynaptic

Stimulate formation of blood-brain barrier

Astrocytes
