Health Science 1 Exam ACTUAL
QUESTIONS AND CORRECT ANSWERS
- Synapse - CORRECT ANSWERS space between neurons; it
permits the neutrons pass messages to and from the brain to other
parts of the body
Function of the Cerebrum - CORRECT ANSWERS
responsible for reasoning, thought, memory, speech, sensation,
sight, hearing, and voluntary movement
Cerebellum - CORRECT ANSWERS The section below the
back of the cerebrum. It is responsible for muscle coordination;
balance and posture; and muscle tone.
Midbrain - CORRECT ANSWERS The section located below
the cerebrum at the top of the brain stem. It is responsible for
conducting impulses between brain parts and for certain eye and
auditory reflexes.
Pons - CORRECT ANSWERS The section located below the
midbrain and in the brain stem. It is responsible for conducting
messages to other parts of the brain; for certain reflex actions
including chewing, tasting, and saliva production; and for assisting
with respiration.
Medulla Oblongata - CORRECT ANSWERS It is the lowest
part of the brain stem. It connects with the spinal cord and it is
,responsible for regulating heartbeat, respiration, swallowing,
coughing, and blood pressure.
Ventricles - CORRECT ANSWERS The ventricles are hollow
spaces that connect with each other and with the space under the
arachnoid membrane (the subarachnoid space); below the atria.
Meninges - CORRECT ANSWERS The meninges are three
membranes that cover and protect the brain and the spinal cord.
Describe and name the three layers of the meninges. - CORRECT
ANSWERS The dura mater is the thick, tough, outer layer. The
middle layer is delicate and weblike and called the arachnoid
membrane. The innermost layer, the pia mater, is closely attached to
the brain and spinal cord and contains blood vessels that nourish the
nerve tissue.
Discuss the cranial nerves and spinal nerves of the somatic nervous
system. - CORRECT ANSWERS Cranial nerves are nerves
that emerge directly from the brain while spinal nerves emerge
directly from segments of the spinal cord.
What is the function of the sympathetic and parasympathetic system?
- CORRECT ANSWERS The sympathetic and
parasympathetic system work together to maintain a balanced state
called homeostasis.
, Describe paraplegia. - CORRECT ANSWERS Paralysis in the
lower extremities or lower part of the body, caused by an injury to the
spinal cord.
Quadriplegia - CORRECT ANSWERS involves paralysis of
both arms and both legs.
Hemiplegia - CORRECT ANSWERS is the paralysis of the
muscles of the lower face, arm, and leg on one side of the body.
Describe what the parasympathetic system does to VS and the
digestive system. - CORRECT ANSWERS The
parasympathetic tries to bring the VS (vital signs) back to normal
(homeostasis) and promotes digestion of food in the digestive system
(it stimulates digestive activity).
Causes of a cerebrovascular accident (CVA) also known as stroke -
CORRECT ANSWERS • When blood flow to the brain is
impaired.
• Cerebral haemorrhage resulting from hypertension.
• By an occlusion, or blockage caused by atherosclerosis or a
thrombus (blood clot).
Emergency treatment for CVA. - CORRECT ANSWERS
Thrombolytic or "clot-busting" drugs such as TPA (tissue
plasminogen activator) or angioplasty of the cerebral arteries can
dissolve a blood clot and restore blood flow to the brain. Immediate
care is necessary in the first 3 hours in order to reduce the chances of
damage to the brain.
