Nervous System, Senses. Animal Behavior. Task No 1: Read the paragraphs in the boxes and
look at the diagram. Then answer the questions.
The nervous system gives directions to all the other systems in your body. It also gets
information from your senses, and keeps track of how well the different parts of your body
are working together. The nervous system is made up of two parts: the central nervous
system (CNS), and the peripheral nervous system (PNS). Peripheral just means “not central.”
Your brain and spinal cord make up your CNS, and send and receive messages through your
PNS.
Your senses allow you to perceive the world by seeing, hearing, feeling, tasting, and
smelling. Your sense organs collect information about the world and send it to your brain.
The brain decodes the signals and makes them meaningful.
Many drugs act to disrupt the normal functioning of the nervous system. Drugs can change
your mood, perception, and your brain’s ability to think and to control the rest of your body.

3. You may not think that caffeine is a drug, but it is. When you drink a soda that contains
caffeine, you may feel “jittery.” Why do you think this is? _____________________________

Nervous System, Senses. Animal Behavior. Task No 2: Read the paragraph in the box and
study the diagram. Then answer the questions.
The nervous system is like a very complicated computer. As in a computer, electrical signals
travel throughout the system. Instead of the wires you would see in a computer, the nervous
system is made up of nerve cells, or neurons. The neurons have gaps between them, called
synapses, which an electrical signal has to jump across in order to continue. Instead of
jumping across the gap as a spark, the impulse is passed across the gap by a chemical signal
called a neurotransmitter.

suddenly blocked? ____________________________________________________________

throughout all of your nervous system? ___________________________________________

Nervous System, Senses. Animal Behavior. Task No 3: The human brain is illustrated here.
Using the word list, identify the labeled parts. Cerebellum, brainstem: midbrain, pons,
medulla; hypothalamus, ventricles, thalamus, pituatiry gland, cerebrum, diencephalon.

Nervous System, Senses. Animal Behavior. Task No 4: The human nervous system. Read
the paragraph in the box. Then answer the questions.
The central nervous system (CNS) comprises the brain and spinal cord. The spinal cord is a
cylinder of nervous tissue extending from the base of the brain down the back , protected
by the spinal column. It transmits massages to and from the brain, and controls spinal
reflexes.
The peripheral nervous system, or PNS comprises all the nerves and sensory receptors
outside the central nervous system.
1. In the human nervous system, briefly explain the structure and role of each of the following:
a) The central nervous system_______________________________________________
________________________________________________________________________
b) The peripheral nervous system ____________________________________________

The PNS comprises sensory and motor divisions. Peripheral nerves all enter or leave the
CNS, either from the spinal cord (the spinal nerves) pr the brain (cranial nerves). They can be
sensory (from sensory receptors), motor (running to a muscle or gland) or mixed (containing
sensory and motor neurons).
The motor division comprises two parts:
Somatic nervous system: the
neuron that carry impulses to
voluntary (skeletal) muscles.
Autonomic nervous system: regulates visceral
function over which there is generally no conscious
control, e.g. heart rate, gut peristalsis involving
smooth muscle, pupil reflex, and sweating
2. Explain the significance of the separation of the motor division of the PNS into somatic
and autonomic divisions:
