What else can I help you with?
What does this mean from an MRI L5 S1 disc space is mildly narrowed and the disc is desiccated reactive signal changes in the adjacent vertebral bone marrow?
If you had an MRI and have a mildly narrowed disc space between L5 S1, it sounds like you have a slightly herniated disc. Whenever your doctor gives you a diagnosis, it is best to ask as many questions as possible such as treatment options, pain management, etc.
Are the spaces between the three meninges in man filled with cerebrospinal fluid?
Yes. Cerebrospinal fluid is a clear liquid produced within spaces in the brain called ventricles. It is a filtrate of blood. It is also found inside the subarachnoid space of the meninges which surrounds both the brain and the spinal chord. In addition, a space inside the spinal chord called the central canal also contains cerebrospinal fluid. It acts as a cushion for the neuraxis, also bringing nutrients to the brain and spinal cord and removing waste from the system.
What is the diastema of a goat?
Diastema is a space or cleft eg the space in the dental arch between the incisors and canines and the cheek teeth which is also called the interdental space
Has a guinea pig been in space?
Yes, a guinea pig named Hector was launched into space in 1961 by the French Centre National d'Études Spatiales. The purpose was to study the effects of radiation and weightlessness on living organisms.
What is a forehead called on a horse?
It is simply called a forehead. But, the space between the ears is called the poll. The poll (this is the point directly between the ears).
What separates the Duran mater from the walls of the vertebral canal?
The dura mater is separated from the walls of the vertebral canal by an epidural space, which contains fat and blood vessels. This space provides cushioning and allows for flexibility within the spinal column. Additionally, the dura mater itself is a tough, outermost layer that protects the spinal cord and its surrounding structures.
What is the space in the meninges that is filled with adipose tissue?
The epidural space is the space in the meninges that is filled with adipose tissue. This space is located between the dura mater and the vertebral canal, providing cushioning and support for the spinal cord.
What is the difference between the vertebral canal and foramen in the spinal column?
The vertebral canal is the hollow space within the spinal column that houses the spinal cord, while the foramen are openings in the vertebrae through which nerves pass.
What are the protective layers around the brain and spinal cord?
Pia Mater, Subarachnoid Space, Arachnoid Mater, Dura Mater, Crainum/Vertebral Bodies.
What organs in vertebral cavity?
Organs in the vertebral cavity include the spinal cord, which runs through the vertebral canal of the spine, along with nerve roots and blood vessels. This cavity is also home to the spinal meninges, which protect and support the spinal cord.
Where is subarachnoid space located?
Between the Arachnoid mater and the Pia mater
What is the difference between meninges of the spinal cord and the brain?
The dura mater in the brain is fused to the periosteum vs in the spinal cord the epidural space is in between the dura mater and the intervertebral canal.Three fibrous membranes that surround the brain and spinal cord to protect the central nervous system. The pia mater, a very thin membrane, adheres to the surface of the brain and spinal cord. The subarachnoid space, containing cerebrospinal fluid, separates the pia mater from a second membrane, the arachnoid. Around the brain, fine filaments connect these two membranes, which are believed to be impermeable to fluid. The third membrane, the dura mater, is strong, thick, and dense. It envelops the arachnoid, covers the inside of the skull, and surrounds and supports the large venous channels carrying blood from the brain. Several septa divide it and support different parts of the brain. In the spine, the dura mater and the arachnoid mater are separated by the subdural space; the arachnoid and pia mater are separated by the subarachnoid space. The extradural space (between the dura mater and the wall of the vertebral canal) is the site of epidural anesthesia (see anesthesiology).
What are the 5 regions of space and meninges between the outer layer of meninges and the cerbral cortex?
The five regions of space between the outer layer of the meninges and the cerebral cortex are the epidural space, subdural space, arachnoid mater, subarachnoid space, and pia mater. The epidural space is located between the dura mater and the skull, while the subdural space lies between the dura mater and arachnoid mater. The arachnoid mater is a web-like structure, followed by the subarachnoid space filled with cerebrospinal fluid, and finally, the pia mater directly covers the cerebral cortex. These layers protect the brain and provide cushioning, nutrients, and waste removal.
What is the subarachnoid space?
The subarachnoid space is a space filled with cerebrospinal fluid located between the arachnoid mater and pia mater membranes that surround the brain and spinal cord. It serves as a protective cushion and helps with the circulation of cerebrospinal fluid.
What is on the outside of the spinal cord?
The outside of the spinal cord is protected by three layers of membranes called meninges: the dura mater (outermost), arachnoid mater (middle), and pia mater (innermost). Between the arachnoid and pia mater is the subarachnoid space, which contains cerebrospinal fluid that cushions the spinal cord. Additionally, the spinal cord is encased within the vertebral column, comprised of individual vertebrae that provide structural support and protection.
Where is the subarachnoid space located?
The subarachnoid space is located between the arachnoid mater and the pia mater, which are two of the layers that surround the brain and spinal cord. It is filled with cerebrospinal fluid, providing cushioning and support to the central nervous system.
What fluid is contained in the arachnoid and pia mater?
Well, technically between the arachnoid mater and the pia mater is the SUBARACHNOID space. This is where the cerebrospinal fluid (CSF) is located.
