pia mater
The membrane between the scalp and the skull is called the periosteum. This membrane is a dense layer of connective tissue that covers and protects the outer surface of the skull bones while also providing attachment for muscles and blood vessels.
The inner surface of the skull is lined with dura mater, which is the tough outermost layer of the three meninges that surround the brain and spinal cord. The pia mater is the innermost layer that is directly attached to the surface of the brain and spinal cord.
Tooth enamel (calcium phosphate) is the hardest substance found naturally in the human body. Unless you're wolverine, who contains adamantium. Or unless you swallow a diamond by accident.
Parietal- Either of two large, irregularly quadrilateral bones between the frontal and occipital bones that together form the sides and top of the skull * American Heritage Dictionary
The outer layer of the meninges is called as Dura matter. It has got the outer or parietal layer. The inner one is called as visceral layer. This layer is very tough in nature. The outer layer is attached to the skull bones. The inner one get along with the folds of the brain tissue. It creates many partitions in the brain. The gaps between the two gives you the various venous sinuses in the meninges.
its the dura mater, the layer is called the periosteal layer.

Periosteum is a membrane that lines the outer surface of all bones, except at the joints of long bones.Endosteum lines the inner surface of all bones.Periosteum consists of dense irregular connective tissue. Periosteum is divided into an outer "fibrous layer" and inner "cambium layer" (or "osteogenic layer"). The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts. These osteoblasts are responsible for increasing the width of a long bone and the overall size of the other bone types. After a bone fracture the progenitor cells develop into osteoblasts and chondroblasts, which are essential to the healing process.
Peri means around and osteum means bone. So periosteum means the structure that surrounds the bone. This fallows that you have endosteum inside the long bones. Also that you have two layers of periosteum for flat bones of the skull bones and no endosteum there. (This layer acts as barrier between the bone and other tissues that is attached to bones.)
The pericranium is the outer layer of a human skull, "James had a small tear in his pericranium when he fell off his motorbike, but fortunately, he did not fracture his skull".
Axial, skull, backbone, bony thorax, appendicular skeleton, upper appendages, periosteum, compact bone, spongy bone.
The inner surface of the skull is lined with dura mater, which is the tough outermost layer of the three meninges that surround the brain and spinal cord. The pia mater is the innermost layer that is directly attached to the surface of the brain and spinal cord.
The outer layer of the dura mater, which is the layer that protects the spinal cord, is a tough fiberous sheath. This sheath also lines the cranial cavity and serves as the periostium to the inner surface.

The skull is not highly porous like some other bones in the body; it has a dense outer layer called the cortical bone, which provides strength and protection. However, the inner layer, known as trabecular or cancellous bone, contains small spaces that can be considered porous. While the skull does have some degree of porosity, it is primarily designed to protect the brain and maintain structural integrity. Overall, the porosity of the skull is relatively low compared to other bones.
Between your skull and your skin lies several layers of tissue, including the meninges, which are protective membranes covering the brain, and the scalp, which consists of skin, connective tissue, and blood vessels. The layers include the periosteum, a dense layer of connective tissue that adheres to the skull, followed by the loose areolar tissue and the skin itself. This complex structure provides protection and support to the brain while facilitating blood circulation and sensation in the scalp.
