Question

Denticulate ligaments are thickenings of _________ that extend and fuse with the ______ and inner surface of the _____a.arachnoid materb.dura materc.pia mater

Answer 1

Answer: The correct answer sequence is PIA MATER, ARACHNOID MATER AND DURA MATER.

Denticulate ligaments are thickenings of PIA MATER that extend and fuse with the ARACHNOID MATER and inner surface of the DURA MATER

Explanation: The pia mater, arachnoid mater and the dura mater are collectively known as the meninges,they are membranes that cover the brain and the spinal cord,they provide protection and support to the structures they cover.(the central nervous system)

THE PIA MATER; This is the innermost layer of the meninges,it is a thin delicate later and made up of connective tissues,it sits/adheres directly to the brain and the spinal cord and provides protection, support and metabolic needs for the central nervous system.

THE ARACHNOID MATER; This is the middle layer of the meninges,it has the appearance of a spider web,it is thin and transparent and covers the spinal cord and as well sits directly over the pia mater.there is a potential space between the pia mater and the arachnoid matter known as the the subarachnoid space,the subarachnoid space contains cerebrospinal fluid and large blood vessels which protects the brain and the spinal cord from any form of trauma and supplies nutrients to the nervous system and also removes waste products after cerebral metabolism.

DURA MATER; The dura mater is the outermost later of the meninges lying directly under the bone tissue, it is made up of irregular connective tissue,it is a thick membrane and it protects the central nervous system and the two inner laters of the meninges.the potential space between the dura mater and the arachnoid mater is know as the subdural space.

Answer 2

Answer:

* ARACHNOID MATER

*DURA MATER

*PIA MATER

Explanation:

denticulate ligaments are bilateral extensions of pia mater that thickening the component of collagen of pia mater.It anchors the spinal cord to the dura mater.They are produced by the pia mater of the spinal cord.They provide stability to the spinal cord within the vertebral canal.

Arachnoid mater helps protect the brain and spinal cord from sudden impact. It is connected to the dura mater at the side that is very close to the central nervous system.

Dura mater refers to the membrane that envelops the arachnoid mater. It surrounds the dural sinuses and also provide supports to it. Dura mater carries blood from the brain toward the heart.

The pia mater is part of pseudolymphatic system and it's referred to as the thin fibrous tissue that allows blood vessels to pass through the brain.
