- Birds have wings.
- Birds lay eggs [source: Britannica].
What are the 12 vertebrates?
There are seven cervical vertebrae, twelve thoracic vertebrae and five lumbar vertebrae….From top to bottom, the vertebrae are:
- Cervical spine: 7 vertebrae (C1–C7)
- Thoracic spine: 12 vertebrae (T1–T12)
- Lumbar spine: 5 vertebrae (L1–L5)
- Sacrum: 5 (fused) vertebrae (S1–S5)
- Coccyx: 4 (3–5) (fused) vertebrae (Tailbone)
How do you identify vertebrates and invertebrates?
Vertebrates have a skeletal structure with a spinal column or backbone. Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.
How can you tell if a vertebra is human?
There are generally three levels of identification that can be utilized to distinguish between human and non-human animal bones: 1) gross skeletal anatomy, 2) bone macrostructure, and 3) bone microstructure (histology).
Where is T4 and T5 in spine?
What are the T4-T8 Vertebrae? The T4-T8 vertebrae make up the rest thoracic vertebrae before the thoracic vertebrae T9 – T12. With the exception of T4, which affects both the chest and abdomen, these vertebrae primarily control abdominal muscles. The T4 and T5 vertebrae are the most commonly injured thoracic vertebrae.
What are the 33 vertebrae?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
What are 5 characteristics of vertebrates?
Like all chordates, vertebrates have a notochord, a dorsal, hollow nerve cord, pharyngeal slits, and a post-anal tail.
What are 4 things that differentiate vertebrates from invertebrates?
Differences Between Invertebrates And Vertebrates
| Invertebrates | Vertebrates |
|---|---|
| Invertebrates do not possess a backbone not an internal skeleton | Vertebrates possess a backbone and an internal skeleton. |
| Invertebrates have an exoskeleton | Vertebrates do not possess an exoskeleton. |
