What is the spinal cord related to?

The spinal cord (in yellow) connects the brain to nerves throughout the body. The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

Information from the skin, skeletal muscle and joints is relayed to the spinal cord by sensory cells located in the dorsal root ganglia. The dorsal root fibers are the axons originated from the primary sensory dorsal root ganglion cells.

Does spinal cord have any other parts?

The spinal cord comprises three parts: the cervical (neck), thoracic (chest), and lumbar (lower back) regions. Three layers of tissue protect the spinal cord: the dura mater, arachnoid mater, and pia mater.

Why is the spinal cord so important?

The spinal cord and the brain together constitute the Central Nervous System. It is an incredibly complex and intricate mesh of nerves. Functioning as the body’s main relay station, the CNS is responsible for all the basic functions of the body, such as breathing, walking, talking, movement, and reflexes.

What parts of the body does the spine control?

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 does a spinal cord look like?

Like the brain, the spinal cord consists of gray and white matter. The butterfly-shaped center of the cord consists of gray matter. The front wings (usually called anterior or ventral horns) contain motor nerve cells (neurons), which transmit information from the brain or spinal cord to muscles, stimulating movement.

Can the spinal cord repair itself?

Unlike tissue in the peripheral nervous system, that in the central nervous system (the spinal cord and brain) does not repair itself effectively.

What are the two main functions of the spinal cord?

The spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the body, and from the afferent fibers of the sensory neurons to the sensory cortex.

What is the function of spinal cord Class 10?

The spinal cord’s major functions include: Electrochemical communication. Electrical currents travel up and down the spinal cord and across nerves, sending signals which allow different segments of the body to communicate with the brain. Walking.

What is the structure and function of spinal cord?

Spinal cord and nerves: The spinal cord is a column of nerves that travels through the spinal canal. The cord extends from the skull to the lower back. Thirty-one pairs of nerves branch out through vertebral openings (the neural foramen). These nerves carry messages between the brain and muscles.
