The pia mater is the innermost protective layer and is tightly associated with the surface of the spinal cord. The space between the arachnoid and pia maters is called the subarachnoid space and is where the CSF is located.
Is there connective tissue in the spinal cord?
Like the brain, the spinal cord is covered by three connective-tissue envelopes called the meninges . The space between the outer and middle envelopes is filled with cerebrospinal fluid, a clear, colourless fluid that cushions the spinal cord.
Which space associated with the spinal cord meninges contains Areolar connective tissue?
Each spinal nerve is mixed, in that it contains some sensory axons and some motor axons. Which space associated with the spinal cord meninges contains areolar connective tissue, blood vessels, and adipose connective tissue? The subdural space is the region between the arachnoid mater and the dura mater.
What is the space within the meninges of the spinal cord that contains the cerebrospinal fluid quizlet?
The subarachnoid space within the meninges contains cerebrospinal fluid.
What are the connective tissue layers surrounding the brain and spinal cord?
The meninges are three protective membrane layers surrounding the brain and spinal cord. They are composed of the pia (closest to the CNS), arachnoid, and dura (outermost layer), and contain blood vessels and enclose the cerebrospinal fluid.
Which spinal nerves affect which parts of the body?
The nerves of the cervical spine go to the upper chest and arms . The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
How do the meninges cover the spinal cord?
The spinal meninges are three membranes that surround the spinal cord – the dura mater, arachnoid mater, and pia mater . They contain cerebrospinal fluid, acting to support and protect the spinal cord.
What protects spinal cord?
The spinal cord is protected by bones, discs, ligaments, and muscles . The spine is made of 33 bones called vertebrae. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine.
What are the three layers of the spinal cord?
The meninges refer to the membranous coverings of the brain and spinal cord. There are three layers of meninges, known as the dura mater, arachnoid mater and pia mater . These coverings have two major functions: Provide a supportive framework for the cerebral and cranial vasculature.
What is the tissue in the spinal cord called?
The spinal cord is composed of nervous tissue . The interior of the spinal cord consists of neurons, nervous system support cells called glia, and blood vessels. Neurons are the basic unit of nervous tissue.
Which infection causes inflammation of the gray matter of the spinal cord?
Poliomyelitis , or gray matter myelitis, is usually caused by infection of anterior horn of the spinal cord by the enteroviruses (polioviruses, enteroviruses (EV) 70 and 71, echoviruses, coxsackieviruses A and B) and the flaviviruses (West Nile, Japanese encephalitis, tick-borne encephalitis).
Which inflammatory disease affects the coverings of the brain and or spinal cord?
Meningitis – An infection or inflammation of the membranes covering the brain and spinal cord.
Which of the following is incorrect about the number of spinal nerves?
| Question Answer | Which of the following is INCORRECT about the numbers of spinal nerves? 7 pairs of cervical spinal nerves | Which of the following parts of a spinal nerve carries sensory information only? posterior (dorsal) root | The anterior root and posterior root fuse to form a(n): spinal nerves |
|---|
What are the functions of spinal nerve?
The spinal nerves receive sensory messages from tiny nerves located in areas such as the skin, internal organs, and bones. The spinal nerves send sensory messages to the sensory roots, then to sensory fibers in the posterior (back or dorsal) part of the spinal cord.
What part of the brain is the transition between the brain and spinal cord?
The medulla oblongata sits at the transition zone between the brain and the spinal cord. It is the first region that formally belongs to the brain (rather than the spinal cord). It is the control center for respiratory, cardiovascular, and digestive functions.
Which Meninge is closest to the brain?
The middle layer of the meninges is called the arachnoid. The inner layer, the one closest to the brain, is called the pia mater or just the pia .
