not work
properly. What problems are likely to arise?

becomes unconscious due to head injury. A pin is
pricked
on his
foot, withdraws his foot. Explain
why?
Section : Interpretation & Reasoning
Each question carries 1 mark:
19 A drunken person generally walks clumsily. Which part of the brain is affected by
alcohol

his respiratory system.
What could
be
the cause of
this
problem?
21 The beating of the heart and hearing sounds are both controlled by the brain. How do
these

has
met
with an accident after that
he lost the capacity
to
(i)walk in straight
line (ii)smell anything (iii)does
not feel full after eating
Which part of brain is damaged
in each case?
23 Draw a well labelled diagram of brain showing – meninges, CSF, cerebrum, pituitary,
cerebellum, pons, medulla oblongata, mid-brain.
24 What is the function
of receptors in
our body? Think of situation where receptors do
not work properly. What are the problems likely
to arise?
.
Section : Problem Solving

label the part: (i)
Where information
is acquired
(ii) Through which information
travels
as
an electrical
impulse-
