Question

Describe the T. S. of Spinal cord.

Answer 1

Hint: The spinal cord is a long, slight, rounded structure composed of sensory tissue, which reaches out from the medulla oblongata in the brainstem to the lumbar area of the vertebral section. It encases the focal channel of the spinal rope, which contains cerebrospinal liquid.

Complete answer:

A segment of nerve tissue, that runs down from the base of the skull to the center point of the back. It is covered by three meager layers of defensive tissue called films. The spinal rope and films are encircled by the vertebrae (spines). The spinal rope and the mind make up the focal sensory system (CNS).

The crossover part of the spinal line shows the accompanying subtleties:
• It is encircled by three meninges-external dura mater, center arachnoid mater, and internal pia mater.
• White issue is external and the dim issue is inward.
• Dim issue is H-molded because of two dorsal horns and two ventral horns. The dorsal horns reach to the dorsal base of spinal nerves and the ventral horns reach to the ventral foundation of the spinal nerves.
• Dark issue consists of cell assemblages of neurons, hand-off neurons, and the glial cells.
• White tissue is composed of myelinated axons.
• 31 sets of nerves emerge from the spinal line.
• In the center, there is a focal trench that contains the cerebrospinal liquid.

Note: The spinal cord works essentially in the transmission of nerve signals from the engine cortex to the body, and from the afferent strands of the tangible neurons to the tactile cortex. It is additionally a center for planning numerous reflexes and contains reflex bends that can freely control reflexes.
