Question

The odd position of jackson's heart is related to a disorder with his cilia called primary ciliary dyskinesia (pcd). What are cilia

Answer 1

Answer and explanation;

-Cilia are numerous motile extensions of the plasma membrane that have an internal arrangement of nine pairs of microtubules surrounding a central microtubule pair (9+2 array).

-Motile cilia are found on cells lining the trachea. The cilia move together in a coordinated wave, helping to push contaminated mucus and fluids out of the respiratory tract. When the cilia have motility issues, these secretions are not cleared, and respiratory infections are the common result.

Answer 2

The cilia are the small filamentous structures having a brush like appearance, which help in the movement of the substances through the lumen in the body.

The cilia are present in various location of the body, such as lining of respiratiry tract, fallopian tube, ear etc.

Primary ciliary dyskinesia is a condition, which is also referred as the immotile ciliary disease. It is a genetic disorder, which causes the stiffness of cilia and do not allow the movement of the substances through the lumens.
