BIOL124 CASE STUDY ANALYSIS 2021 (35 MARKS)
CASE STUDY ONE: NERVOUS SYSTEM (9 marks)
Question 1 (3 marks)
Q1).The space between the arachnoid layer and the underlying pia mate
CSF gives the brain protection by acting as soft barrier against impact.
CSF supplies sustenance to the nervous system and removes waste. It flows
through the four interconnected ventricles of the brain and through the
spinal cord’s narrow central canal’s also escapes through small openings
from the fourth ventricle at the base of the brain to enter the subarachnoid
space. CSF is reabsorbed from the subarachnoid space into the venous
blood through the arachnoid villi
Question 2 (3 marks)
Q2). Subarachnoid stroke
After the surgery, the Glasgow Coma Scale (GCS) showed poor verbal
and motor scores. Thomas could hear but could not initiate speech.
Further, he had severe muscle weakness on the right side of his body.
Gathered blood will bring about high BP. Extreme headache, vomiting is
another sign of high BP
Question 3 (3 marks)
.
Q3). Left side of the brain effected. Frontal lobe (Broca), causing motor
weakness. Dialogue issues and mobility of the right half of body is

which control dialogue and mobility of the right appendage are effected.
