Rückenmarkshäute und Nervenwurzeln

The video tutorial provides an in-depth look at the spinal cord, its structure, and its role in the central nervous system. It covers the anatomy of the spinal cord, including the gray and white matter, and explains the function of the spinal cord membranes. The tutorial also discusses the spinal nerves, their roots, and the rami communicantes, as well as the blood supply to the spinal cord through the anterior and posterior spinal arteries.

What is the primary function of the white matter in the spinal cord?

• To store nutrients

• To protect the spinal cord

• To produce cerebrospinal fluid

• To transmit information within the nervous system

Which structure is responsible for the fast transmission of information in the white matter?

• Cerebrospinal fluid

• Myelin

• Central canal

• Gray matter

What is the dura mater spinalis primarily responsible for?

• Connecting to the brain

• Transmitting sensory information

• Protecting the spinal cord

• Producing cerebrospinal fluid

What is the clinical significance of the subarachnoid space?

• It produces myelin

• It stores nutrients

• It connects to the brain

• It is used for lumbar puncture

What is the role of the pia mater spinalis?

• To transmit motor signals

• To supply blood to the spinal cord

• To produce cerebrospinal fluid

• To protect the spinal cord

How do sensory signals reach the spinal cord?

• Via the posterior root

• Via the central canal

• Via the dura mater

• Via the anterior root

What is the function of the anterior ramus of a spinal nerve?

• To protect the spinal cord

• To transmit only sensory information

• To transmit only motor information

• To transmit both motor and sensory information

What is the role of the rami communicantes?

• To connect the spinal nerve with the sympathetic trunk

• To transmit sensory information

• To produce cerebrospinal fluid

• To protect the spinal cord

Where does the anterior spinal artery originate?

• From the carotid arteries

• From the bralic arteries

• From the aorta

• From the vertebral arteries

What does the posterior spinal artery supply?

• The anterior third of the spinal cord

• The entire spinal cord

• The posterior third of the spinal cord

• The central canal
