Question

Ependyma is
A.Ciliated pseudostratified columnar epithelium
B.Ciliated columnar epithelium
C.Ciliated cuboidal epithelium
D.Non-ciliated columnar epithelium

Answer 1

Hint: The ependyma is organized of ependymal cells named ependymocytes, a kind of glial cell. These cells line the ventricles in the brain and the prominent duct of the spinal cord, which serve restored with cerebrospinal fluid.

Complete answer:
Before we discuss the correct options, let us know a little more about Ependyma. Ependymoma is a tumour of the ependymal cells most normally established in the fourth quarter of the ventricle.

Option B: Ependyma is the tiny epithelium lining in the ventricles of the brain and the main trench of the spinal cord. These are ciliated reasonable columnar epithelium cells. These are pertained to in the output of cerebrospinal fluid (CSF). Therefore, this is the correct option.

As option B is the correct answer, therefore option A, C and D is incorrect.

Ependymal cells line the ventricles of the brain, and at a particular configuration called the choroid plexus, one of which is establish in each ventricle, ependymal cells shape a secretory epithelium that generates the CSF that replenishes the ventricles and bathes the whole CNS.

Hence, the correct answer is option (B)

Note: The ependyma is the tiny neuroepithelial lining of the ventricular network of the brain and the central tube of the spinal cord. The ependyma is one of the four kinds of neuroglia in the central nervous strategy (CNS).
