Overview of Giraffe

Giraffes spread in the open savannah areas, and in the forest pastures for Eastern and Southern Africa; Where these pastures is characterized by an abundance of acacia trees, and shrubs, and can be identified by these animals through the long legs and slender, and fur-covered spots; Where most of the giraffes are characterized by skin white color, or brown, or yellow topped with spots almost square structure shape, but for the scientific classification of the giraffe it belongs to the family Alzraviac that follow the rank of Hfieat fingers, which follow in turn to a variety of mammals, under the chordates Division, which belong in the end Animal Kingdom. [1] [2]

It should be noted that there is a study published in the journal (current biology) in 2016 showed that giraffes do not all belong to one species, but belong to the four sub-types, namely: North Giraffe (Giraffa camelopardalis), South Giraffe (Giraffa giraffa), giraffe retina (Giraffa reticulata), giraffe or Kilimanjaro Masai (Giraffa tippelskirchi). [3]

Neck Giraffe

Neck Giraffe length

The length of the giraffe's neck to 1.8 meters and can weigh up to about 272 kg; Where it is Giraffes longer wild animals, for example, it can look to a window located on the second floor with ease, and it is worth mentioning that the neck of the giraffe has only seven vertebrae as humans completely, but the length of each of which may exceed 25.4 cm. [4]

Adaptation of the neck of the giraffe

Arteries with thick walls in the neck containing giraffe additional valves to minimize the influence of gravity when the head of the giraffe is brought, [5] as giraffes have a big heart with a length when an adult male to 60 cm, which generates pressure bloody great is equal to twice the pressure generated by human heart, or other large mammals, and the face of this high pressure near the heart, the walls of the arteries is characterized by a high flexibility. [6]

Characterized by paragraphs that are found in the neck of the giraffe on the strap known as its proximity in Rabat nuchal (in English: Nuchal Ligament) extends from the back of the skull to the base of the tail, and the increasingly thick above the shoulders directly; This ligament helps to reduce the weight of the head of the giraffe and her neck, and works like a rubber band to flatten a huge giraffe's neck up, which reduces the amount of energy needed by the muscles to carry the head. [6]

When you lower the giraffe head to eat it is likely that the high blood rushes pressure down, causing blood vessels sensitive explosion in the brain and eyes, but there are many changes that occur in the arteries, which cause reduced blood flow to the brain and turn instead to a network of small blood vessels (in English: Rete Mirabile) located near the brain, which in turn expands to accommodate the increase in blood pressure, and the valves in the veins prevent blood back jugulo down during the low head. [6]

Characterized by the neck of the giraffe high flexibility, and the reason for this is that the existing paragraphs in the neck are linked together by a hinge-type spherical acetabular (in English: Ball and Socket Joint), which helps the giraffe to move her neck at an angle 360, and the first and second paragraphs of the thoracic spine of the giraffe ( English: Thoracic Vertebrae) linked by a hinge bearing my right as in the cervical vertebrae, which increases the flexibility of the neck also dramatically. [7]
