INTRODUCTORY MEDICAL SURGICAL
NURSING LORETTA ACTUAL TEST 2026
SOLVED QUESTIONS ANSWERS VERIFIED A+
◉ 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). Answer: A subdivision of the
autonomic nervous system that activates nerves, glands and visceral
muscles in times of stress or threat (prepares the body for action)
◉ Synapses. Answer: Special junctions where neurons communicate
with other neurons and cells
◉ Ventricles. Answer: Interconnected cavities within the cerebral
hemispheres and brain stem
