Question

Are human vertebrates?

Answer 1

- Vertebrates are all animal types that belong to the Vertebrata subphylum, chordates with backbones.
- Vertebrates make up the vast majority of the Chordata phylum, with approximately 69,963 species currently recognized.

Complete answer:
- A vertebrate is an animal with a vertebral column (spine), a central column of bones called vertebrae that stretches from the base of the skull to the coccyx and is interconnected by ligaments, muscles, and tendons and divided by spongy discs.
- Various bones, such as ribs, pelvic bones, and the skull, are fused to the spine. When the body is in motion, the spine retains horizontal control of the body alignment of most species with such a complicated structure. The spine in humans is flexed outward from the base of the neck and backward under the ribs, with another outward flex as it reaches the pelvic girdle.
- Vertebrates share many characteristics with chordates, including a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. The vertebral column, which forms as the notochord develops into a column of bony vertebrae divided by discs, separates vertebrates from chordates.
- The ability of Homo sapiens to stand, walk, and run in an upright pose is largely due to this compound-complex flexure.

Thus from the above discussion humans are vertebrates.

Note:
- Human Skeleton is made of more than 200 bones.
- Babies are born with 300 bones.
- Warm-blooded and cold-blooded vertebrate animals exist. A cold-blooded animal can't keep its body temperature stable. The temperature of their bodies is affected by the climate.
- Cold-blooded animals switch between the shade and the sun during the day to warm up or cool down.
