How Do You Spell ARACHNOID MEMBRANE?

Pronunciation: [ɐɹˈaknɔ͡ɪd mˈɛmbɹe͡ɪn] (IPA)

The spelling of the word "arachnoid membrane" can be tricky because of the silent letters in it. The correct pronunciation of this word is [əˈræk.nɔɪd ˈmɛm.breɪn], with the stress on the second syllable. The word "arachnoid" originates from the Greek word "aráchnē" which means spider, and the word "membrane" indicates a thin protective layer. Therefore, the "arachnoid membrane" refers to a thin layer that surrounds the brain and spinal cord, resembling a spider web.

ARACHNOID MEMBRANE Meaning and Definition

1. The arachnoid membrane is a delicate and transparent middle layer of the three meninges that protect and enclose the brain and spinal cord. It lies between the tough, outermost layer known as the dura mater, and the innermost layer called the pia mater. The term "arachnoid" is derived from its appearance, which resembles a delicate web-like structure when examined under a microscope.

   The arachnoid membrane is composed of a thin layer of connective tissue that contains a network of blood vessels. It forms a protective barrier between the dura mater and the pia mater, providing support and cushioning for the brain and spinal cord. It also helps to facilitate the flow of cerebrospinal fluid (CSF), a clear fluid that surrounds and nourishes the central nervous system.

   In certain areas of the brain, such as the cerebral hemispheres, the arachnoid membrane extends inward, creating projections known as arachnoid trabeculae, which connect it to the pia mater. These trabeculae help to maintain the position of the brain within the skull and assist in the circulation of cerebrospinal fluid.

   Disorders or conditions that affect the arachnoid membrane can lead to various neurological symptoms. For example, an arachnoid cyst, which is a fluid-filled sac that develops within the arachnoid membrane, may cause headaches, seizures, or issues with motor or sensory function. Understanding the anatomy and function of the arachnoid membrane is crucial for diagnosing and treating such conditions.
