INTRODUCTORY MEDICAL SURGICAL
NURSING TIMBY SMITH PRACTICE QUESTIONS
AND DETAILED SOLUTIONS
◉ Decorticate Posturing.
Answer: characterized by upper extremities flexed at the elbows and
held closely to the body and lower extremities that are externally
rotated and extended. occurs when the brainstem is not inhibited by
the motor function of the cerebral cortex.
◉ Dendrites.
Answer: Branchlike parts of a neuron that are specialized to receive
information.
◉ Dopamine.
Answer: A neurotransmitter associated with movement, attention
and learning and the brain's pleasure and reward system.
◉ Dura Matter.
Answer: Thick outermost layer of the meninges surrounding and
protecting the brain.
,◉ Epinephrine.
Answer: A catecholamine secreted by the adrenal medulla in
response to stress preparing the body for "flight or fight" (trade
name Adrenalin)
◉ Extrapyramidal.
Answer: are involuntary movements that result mainly from taking
first-generation antipsychotic drugs
◉ Flaccidity.
Answer: Low muscle tone
◉ Medulla Oblongata.
Answer: A portion of the brainstem that regulates vital functions,
including breathing, heart rate, and blood pressure.
◉ Meninges.
Answer: three layers of connective tissue in which the brain and
spinal cord are wrapped
◉ Midbrain.
Answer: A small part of the brain above the pons that integrates
sensory information and relays it upward.
,◉ Myelin.
Answer: A layer of fatty tissue segmentally encasing the fibers of
many neurons; enables vastly greater transmission speed of neural
impulses as the impulse hops from one node to the next.
◉ Neurilemma.
Answer: membranous covering that protects the myelin sheath
◉ Neuron.
Answer: Nerve cell
◉ Neurotransmitters.
Answer: Chemical messengers that cross the synaptic gaps between
neurons. When released by the sending neuron, neurotransmitters
travel across the synapse and bind to receptor sites on the receiving
neuron, thereby influencing whether that neuron will generate a
neural impulse.
◉ Norepinephrine.
Answer: A precursor of epinephrine that is secreted by the adrenal
medulla and also released at synapses.
◉ Parasympathetic Nervous System.
, Answer: A subdivision of the autonomic nervous system that calms
the body after action and also retains the body functioning at is
normal state (homeostasis)
◉ Peripheral Nervous System (PNS).
Answer: sensory and motor neurons that connect the CNS to the rest
of the body
◉ Pia Mater.
Answer: Inner layer of meninges; intimately attached to brain
following contours; carries small blood vessels to nourish
underlying nervous tissue;
◉ Pons.
Answer: A hindbrain structure that connects the medulla to the two
sides of the cerebellum; helps coordinate and integrate movements
on each side of the body
◉ Subarachnoid Space.
Answer: a space in the meninges beneath the arachnoid membrane
and above the pia mater that contains the cerebrospinal fluid
◉ Sympathetic Nervous System (SNS).
