SPECIAL
Giraffes are the tallest living land animals.
Adults females can grow 14 feet and adults mail
can reach 18 feet Exceptional hight allows giraffes
to eat leaves from trees
Giraffes have exceptionally strong heart Its about 2
feet long and weight approximately 25 pounds equal
to 50 Human Heart

Giraffes heart has evolved thick muscular wall
Giraffes are the most iconic feature in Africa
Baby Giraffe are called calves and may grow 1inch
everyday
Giraffes have the same number of neck bones as
Humans
Giraffes neck is equal to 6 feet

The Role of the
Neck in the
Movements of
the Giraffe
The role of the neck in the movement of the
giraffe was studied by examining motion
picture sequences of wild giraffe.
Unlike in the horse, the forequarters in the
giraffe are stronger than the hindquarters.
When beginning a galloping or a walking
stride, the neck moves forward in line with the
power stroke of the forelegs, thus decreasing
the weight on the hind legs and moving the
centre of gravity of the animal forward.
At the end of each stride, when the hoofs again touch the
ground, the neck moves backward in order to decrease the
forward momentum of the giraffe and enable him to keep his
balance.
When the angle of the neck on the back is plotted against time,
the graph is like a sine curve.
The movements of a giraffe climbing a fence, getting up from
lying down and raising himself from the drinking position are
considered briefly.
How do Giraffes walk
Giraffes move both legs on one side and then both legs
on the other side. In some cases, the hind leg starts
first so there is a slight lag.
This is also called ‘Pacing’ .
The trot is the same gait as the dog walk, but faster –
so that there is a moment in each stride when all four
legs are off the ground.
Locomotion of Giraffe

When giraffes walk, they move
both legs on one side of their body
and then both legs on the other
side, which is unusual.
However, they run in a similar
style to other mammals, swinging
their rear legs and front legs in
unison.
They can reach 55 km/h (35 mph)
at full speed but only in brief
spurts
A Giraffes skinny legs look like tgey
could collapse at any second under the
animal immense weight
But their legs are enough to support at
2200 lb body
Having elongated legs Giraffes are
equipped with pieces of connective tissue ,
called SUSPENSORY LIGAMENTS
SUSPENSORY LIGAMENTS : Which is made of elastic tissue not
muscle tissue
Allows Giraffes to conserve energy.
They don’t have to engage as much muscle to support their weight
Researchers also think the ligments prevent the foot joints from
overextending and collapsing

LOCOMOTION IN SLOW MOTION
The total time between stimulus onset and
force production (response time) incorporate
delay due to sensing the stimulus.
Responsiveness may depends upon animal
size.
Delay association with nerve conduction ,
electromechanical processes and force
generation have the potential to
substantially increses in larger animals
calculated the onset of muscle
activity as the time at which the EMG
signal crossed a threshold of 20% Of
the magnitude of its first peak.
This represented muscle activity
caused by impulses in the motor
axons stimulated by the stimulating
electrodes.
