Question

In humans, the coccyx is formed by the fusion of which of the following number of vertebrae?
A. 3
B. 4
C. 5
D. 6

Answer 1

Hint: The spine of an individual has 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 3 to 5 coccygeal vertebrae. The human, the coccyx is three-sided framed boned.It is a rest of a lacking tail. The coccyx bone is ordinarily joined to the sacrum.

Complete answer:
The coccyx is a three-sided coccyx, added to the sacrum by an intervertebral plate (3 to 5 consolidated bones). It is routinely laid out by the blend of 4 vertebrae under the sacrum. The tailbone, commonly proposed as the tailbone, is masterminded under the sacrum. Just, the sacrum and coccyx are associated with more inconspicuous bones that weave (change into strong bone mass) together in their 30s. The sacrum includes 5 joined vertebrae (S1-S5) and 3 to 5 little bones consolidated to make the tailbone.

Additional information:
Despite how it is substantially more unassuming than the sacrum, it additionally expects a basic part in weight-bearing. The tailbone keeps up your weight while sitting. In the event that you recline while sitting, for instance reclining in a seat, the tension on your tailbone increments.

So, the correct answer is ‘4 vertebrae’.

Note:
The sacrum is found as a crazy bone. The restriction of the tailbone is to disperse weight between the lower part of the hip bones (or ischium) and the tailbone, giving concordance and security when the individual is organized. The tailbone is the alliance point for specific muscles in the pelvic floor. The messed up tailbone causes all things considered, solid dull hurt in the low back ridiculous, which is all the more horrendous when sitting and ascending from a sitting position, creating around the tailbone.
