ASU BIO 201- Practical GUIDE| Questions with
100% Correct Solutions
Neuron (appearance) - ANSWER round bodies with fibrous processes (axon and
dendrites) extending from the neurosoma; surrounded by smaller glial cells which lack
axons and dendrites
Neuron (functions) - ANSWER internal communication
Neuron (locations) - ANSWER brain, spinal cord, nerves, ganglia
Neuron Body - ANSWER - Soma
- houses the organelles and acts as a control center for the neuron
Neuron Dendrites - ANSWER branched projections which receive signals from other
neurons
Neuron Axon - ANSWER carries signals away from the soma
Myelin Sheath - ANSWER lipid-rich insulation enveloping the axon
Node of Ranvier - ANSWER gaps in the myelination which allow for passage of ions
Oligodendrocyte - ANSWER - Neuroglia (Glial Cells)
- bulbous body with as many as 15 arms which envelop nerve fibers
Oligodendrocyte (locations) - ANSWER brain and spinal cord (central nervous system)
, Schwann Cell - ANSWER - Neuroglia (Glial Cells)
- envelop a single nerve fibers in the peripheral nervous system (PNS)
Schwann Cell (locations) - ANSWER all nerves except the brain and spinal cord
(peripheral nervous system)
Gray Matter - ANSWER superficial in brain, deep in spinal cord
White Matter - ANSWER - superficial in spinal cord, deep in brain
- myelin rich and contains tracts that connect parts of the brain and spinal cord
Central Nervous System (CNS) - ANSWER composed of the brain and spinal cord
Peripheral Nervous System (PNS) - ANSWER composed of any nerve or ganglia outside
of the CNS
Sensory (Afferent) Division - ANSWER carries signals from various receptors (sense
organs and nerve endings) to the CNS
Visceral Sensory Division - ANSWER carries signals from thoracic and abdominal viscera
Motor (Efferent) Division - ANSWER carries signals from the CNS to glands and muscle
cells
Visceral Motor Division (Autonomic Nervous System, ANS) - ANSWER carries signals to
glands, cardiac muscle, and smooth muscle; responsible for visceral reflexes
