Questions Answered Correctly (Qs) 2026
update
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.
