Spinal Cord
The spinal cord is long, cylindrical rod present inside the neural canal of vertebral column. It is a part of central nervous system and controls reflex actions of the body.

The ventral rami of spinal nerves C5 to C1 contribute fiber to what plexus?
The ventral rami of spinal nerves C5 to T1 contribute fibers to the brachial plexus. This plexus is responsible for innervating the muscles and skin of the shoulder, arm, and parts of the hand. It plays a crucial role in motor and sensory functions of the upper limb.
Is spinal chord a reproductive organ?
No, the spinal cord is not a reproductive organ. It is a part of the central nervous system, responsible for transmitting signals between the brain and the rest of the body, as well as coordinating reflexes. Reproductive organs, such as the ovaries and testes, are specifically involved in the production of gametes and hormones related to reproduction.
What is the conduct function of the spinal cord?
The conduct function of the spinal cord refers to its role as a major pathway for transmitting nerve impulses between the brain and the rest of the body. It facilitates communication by relaying sensory information from peripheral receptors to the brain and motor commands from the brain to muscles and glands. Additionally, the spinal cord is involved in reflex actions, enabling quick responses to stimuli without direct involvement from the brain.
Are dorsal and ventral roots spinal nerves?
The ventral roots contains motor fibers, responsible for motion, whereas the dorsal sensory fibers, responsible for touch and feeling.
Cerebral spinal fluid serves what purpose?
== == CSF works as a cushion for your brain. Essentially your brain floats in it. It surrounds the brain and spinal chord to protect it, say from a sudden shock.
The longitudinal bundle of nerve fibers within the spinal cord that constitutes major nerve pathways is called the "white matter." It contains ascending and descending tracts that transmit sensory and motor information between the brain and the rest of the body. The major tracts include the corticospinal tract for motor control and the spinothalamic tract for pain and temperature sensation. These pathways are crucial for coordinating movement and processing sensory information.
Whether surgery is needed for an L5-S1 posterior disc extrusion depends on several factors, including the severity of symptoms, the duration of those symptoms, and the response to conservative treatments like physical therapy or medication. If the extrusion causes significant pain, neurological deficits, or if conservative treatments fail, surgical intervention may be recommended. A thorough evaluation by a healthcare professional is essential to determine the best course of action.
What are Spinal Specialists called?
That would be a neurosurgeon. They specialize in brain and spinal surgery.
Which neurons transmit information to the brain and spinal cord?
Sensory neurons gather information and send it to your spinal cord.
