How many vertebrae do horses have?
Fifty four (54) vertebrae for the typical horse. Cervical vertebrae: 7: the neck Thoracic vertebrae: 18 : the back, above rib cage Lumbar vertebrae: 6: the back, just above and forward of rear hip bones Sacral vertebrae (5 fused together - sacrum): just above and behind rear hip bones Coccygeal vertebrae (average 18): the tail source: http://www.kersur.net/~santa/skeletalsystem.html source: http://www.allabouthorses.com/horse-health/injuries/horse-anatomy.html
What are the three other groups of vertebrae animals?

In what order did the five classes of vertebrates evolve?

5 animals with bones on the outside of the body?
* Some creatures, called arthropods, have skeletons outside their bodies. These are insects (like ants and bees), arachnids (spiders and scorpions), and crustaceans (sea creatures like crabs and lobsters). These creatures all have skeletons made of hard plates or shells. This kind of skeleton is called an exoskeleton. Arthropods (phylum Arthropoda) are a group of invertebrates, which means they don't have backbones (vertebrae). Insects, spiders, crabs, shrimp, millipedes, and centipedes are all arthropods.
What are the groups of vertebrae?
There are Five different types of Vertebrae in the Vertabral collumn (spine).1) Cervical Vertebrae (7)2) Thoracic Vertebrae (12)3) Lumbar Vertebrae (5)4) Sacral Vertebrae (5)5) Coccygeal Vertebrae (3)
Where is the vertebrae located in the lower back are the?
The lumbar vertebrae, there are 5 lumbar vertebrae.
What are the five categories of vertebrae in your vertebral column?
The five types of vertebra are the:cervical vertebrae (neck)thoracic vertebrae (chest)lumbar vertebrae (back)sacral (pelvis)coccyx (tailbone)
How many lumbar vertebrae are there in a typical adult skeleton?
There are 5 lumbar vertebrae.
How many bones does the human back have?
7 cervical vertebrae + 12 thoracic vertebrae + 5 lumbar verterbae + 5 sacral vertebrae + 4 caudal vertebrae = 33
How many vertebra do human have?
Almost all humans are born with 33 separate vertebrae. By adulthood, most have only 24. This is due to the fusion of the vertebrae in certain parts of the spine during normal development. Different textbooks give different answers to this question. The confusion comes from the fact that the two lowest vertebrae -- the sacrum and the coccyx -- are each one bone, but they are made up from smaller bones fused together. There are 24 separate vertebrae; then there is the sacrum, which is formed from 5 fused vertebrae; and finally the coccyx, which is formed from between 3-5 fused vertebrae. Therefore, if the coccyx and sacrum are each classed as one vertebra, then there are 26 vertebrae. If the fused vertebrae are all counted separately, then there are 32-34 vertebrae.
What is the top most vertebra of your spine called?
There are 33 Vertebrae, starting from the top (just under skull) there are: 7 cervical vertebrae 12 thoracic vertebrae 5 lumbar vertebrae 5 sacral vertebrae (fused together) 4 coccygeal vertebrae (fused together)
What are the bones in the spine?
The bones of the spine are called vertebrae. There are 33 total vertebrae in 5 regions: cervical (7), thoracic (12), lumbar (5), sacral (5), and coccygael (4). (The 5 bones of the sacral region are fused, as are the 4 bones of the coccygeal region.)
How many bones are in the adults back?
It usually consists of 33 vertebrae and is divided into 5 different types: cervical (7), thoracic (12) lumbar (5), sacral (5 - fused) and coccygeal (4 - fused) vertebrae. Your back bone consists of 7 cervical vertebrae (making the neck), then 12 thoracic vertebrae, and 5 lumbar vertebrae.
Can a human have 34 vertebrae?
Yes. The human spine is made up of three parts, the cervical spine(neck), the thoracic(middle), and the lumbar (lower back). The lumbar consists of 5 vertebrae in the average adult human, but may also only have 4 or 6 vertebrae depending on the individual, although this is not as common. There can be sacralization of the 5th lower lumbar resulting in only 4 lumber vertebrae, or a vertebrae of the sacrum where the individual has an extra 6th lumbar vertebrae. While all adults have 7 cervical vertebrae there is much more variation in the thoracic and lumbar vertebrae. The thoracic too may have a 13th vertebrae resulting in an extra rib. And as mentioned before the lumbar may have 4-6 vertebrae depending on the individual.
How many vertebrae are in a black person?
An African human is just like a human from any other part of the world. All humans have 33 Vertebrae split into 5 regions. The top 7 are called the Cervical Vertebrae, then Next 12 are called the Thoracic Vertebrae, then the 5 Lumbar Vertebrae. All the vertebrae mentioned so far are free individual bones that are joined at their Vertebral Bodies by special cartilagenous joints called Intervertebral Disks. The next region down is the Sacral region (or Sacrum) within which all 5 vertebrae are fused to form effectively one bone. And the final 4 vertebrae are also fused to oneanother to form a structure known as the Coccyx. This adds up to a total of 33 vertebrae, present in all healthy human being. In plainer terms, healthy babies are born with 33 vertebrae, and through fusion a healthy adult is left with 26.
How many vertebrae do lion have?
The Lion is a mammal and all mammalian animals have 33 vertebrae. The Giraffe, being mammalian, also has 33 vertebrae. The length of the Giraffe's neck obviously indicates each vertebrae bone would be considerably longer neck-wise than that of the Lion. Mammalian vertebrae are divided into 5 sub-groups and head down they are; Cervical 7, Thoracic 12, Lumbar 5, Sacral 5 and Coccyx 4.
