Question 1 (4 marks)

What is the difference between the Central Nervous System (CNS)
and the Peripheral Nervous System (PNS)?

Answer:
The human nervous system is divided into two main parts: the Central
Nervous System (CNS) and the Peripheral Nervous System (PNS).
Both systems work together to control body functions, but they differ in
structure, protection, and role.

1. Components:
o The CNS is composed of the brain and spinal cord, which
serve as the primary control centers of the body.
o It processes information from all parts of the body and
coordinates responses.
o The PNS includes all the nerves that branch out from the
CNS to the rest of the body.
o These nerves transmit sensory information to the CNS and
motor commands back to muscles and glands.
o Essentially, the CNS is the “command center,” while the PNS
is the “communication network.”
2. Function:
o The CNS interprets incoming information and makes
decisions on how the body should respond.
o It is responsible for higher-order functions such as thought,
memory, and decision-making.
