PATHOPHYSIOLOGY FOR THE HEALTH
PROFESSIONS PRACTICE SOLUTION 2026
QUESTIONS WITH FULL SOLUTION GRADED
A+
◉ PNS. Answer: Cranial and spinal nerves, sensory neurons,
neuromuscular junctions
◉ Brain. Answer: control center of body, receives, processes,
evaluates info & initiates response
◉ Meninges. Answer: 3 connective tissue layers covering brain and
spinal cord
◉ Dura matter. Answer: Is the outermost tough double layered
membrane of the meninges
◉ Pia matter. Answer: Is a very thin membrane that adheres closely
to the brain and spinal cord (part of meninges)
◉ Cerebrospinal fluid. Answer: Shock absorbing fluid, provides
cushion for brain and spinal cord, formed in choroid plexus
, ◉ Arachnoid. Answer: 2nd of meninges, weblike thin delicate
membrane
◉ Subarachnoid space. Answer: Contain CSF
◉ Arachnoid villi. Answer: are projections of arachnoid into dural
sinuses where csf can be absorbed into venous blood
◉ Blood brain barrier. Answer: is a barrier that limits passage of
damaging materials into brain but allows lipid substances to pass,
controls balance of electrolytes, is poorly developed in neonates
◉ Blood CSF barrier. Answer: Located at choroid plexus, controls
constituents of CSF
◉ Cerebral hemispheres. Answer: Largest area of brain, longitudinal
fissure separates two hemispheres, covered by elevations called gyri
separated by grooves called sulci
◉ Subdural space. Answer: lies beneath the dura and is a potential
space
◉ Choroid Plexus. Answer: areas of highly vascularized tissue
located in each of 4 ventricles of brain
