The layer of the meninges that serves as the inner periosteum of the cranial bone is the?
Meninges are the membranes around the brain and spinal cord and there are three distinct layers.
1. Dura mater (tough mother): outermost membrane, tough, white fibrous CT which contains many blood vessels & nerves.
2. Arachnoid Mater (spider mother): a middle layer; thin net-like membrane.
Beneath the arachnoid mater lies a wide space called the sub-arachnoid space filled with cerebrospinal fluid (CSF) and serves as a cushion for the brain.
3. Pia Mater (delicate mother): the inner layer that clings to brain surface; dips into grooves & contours.

Function of the periosteum?
The periosteum serves as an attachment point for muscles and bones through tendons and ligaments.Periosteum: membrane lining outer surface of bones. Functions: [1] osteoblasts (increase bone width), [2] healing process (after break), [3] nerve endings (sensitive to manipulation), [4] provides nourishment (blood supply).
The what is the structure of the periosteum?
AnswerThe Periosteum serves as an attachment point for muscles and bones through tendons and ligaments. -----------------------------------------------------------------------------------------------------------Or, Inner layer can breakdown and build bone cells. Not necessarily its "function". It's a fibrous membrane covering (of bone), attached by fibers that happen to enter into bone, "Sharpey's fibers"; allowing nerves, and blood / lymphatic vessels to pass though it and then into bone through nutrient foramina. The periosteum covers bone and provides nourishment to the bone through the blood vessels and nerves contained within it.
What is the difference between the periosteum and the endosteum?
The periosteum a membrane with a fibrous outer layer and a cellular inner layer. The periosteum isolates the bound surrounding the tissue, provides a route for the circulatory and nervous supply and actively particiapates in bone growth and repair. The endosteum an incomplete cellular layer, lines the marrow cavity. This layer which is active during bone growth, repair, and remodeling, covers the trabeculae of spongy bone and lines the inner surfaces of the central canals.
Where can you find the periosteum?
The periosteum is a dense layer of connective tissue that covers the outer surface of bones. It can be found surrounding most bones in the body, providing support and protection to the underlying bone structure.
Difference between periosteum and endosteum?
The periosteum is a dense membrane of connective tissue that covers the outer surface of bones, while the endosteum is a thin layer of connective tissue that lines the inner surface of bones. The periosteum is involved in bone growth, repair, and nutrition, while the endosteum is involved in bone remodeling and repair.
How do the periosteum and endosteum differ in thickness?
The periosteum is typically thicker than the endosteum. The periosteum is the membrane that covers the outer surface of bones, while the endosteum lines the inner surface of bones.
What is the name of inner lining of ventral of brain?
The inner lining of the ventral (bottom) surface of the brain is called the meninges. It is made up of three layers - the dura mater, arachnoid mater, and pia mater - and serves to protect the brain and spinal cord.
What is the tough outermost layer of the meninges?
The outermost layer of meninges is called as Dura matter. It has got outer and inner layers in Dura matter. Together they form various venous sinuses in the meninges.
What is the job the three meninges (membranes) that cover the brain?
The meninges consist of three layers of tissue between the skull and the brain and the spinal cord. From outside to inside : dura mater, arachnoid mater and pia mater. The inner two layers are filled with cerebrospinal fluid.
Are large number of osteocytes found in the inner periosteum?
yes.

What is the Membrane that lines the inside of the skull?
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.

What covers the long bones?
The dense fibrous tissue that covers non articulating surfaces of bone is the periosteum.
What is the function of the internal auditory meatus?
The internal auditory meatus is a canal in the temporal bone of the skull that serves as a passageway for the facial nerve (cranial nerve VII) and the vestibulocochlear nerve (cranial nerve VIII), which are crucial for hearing and balance. It also allows for the entry of blood vessels and other structures supplying the inner ear. This anatomical feature plays a vital role in transmitting sensory information from the inner ear to the brain.
