Which of the three spinal meninges is the most superficial?

The given question is not complete, the complete question is:

Which of the three spinal meninges is the most superficial?

A) Arachnoid mater

B) Dura mater

C) Meninx mater

D) Pia mater

E) Epi mater

The correct answer is option B, that is, dura mater.

Explanation:

The three of the membranes that envelopes the spinal cord are known as the spinal meninges. These are the arachnoid mater, dura mater, and the pia mater. These membranes comprise a cerebrospinal fluid, that helps in protecting and supporting the spinal cord.  

Of the three spinal meninges, the dura mater is the most superficial one. Of all the meninges, the most external one is the dura mater. It covers the space between the foramen magnum to the filum terminale and is distinguished from the boundaries of the vertebral canal via the epidural space.  

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
