Lumber Spinal Cord

Front

What is the central canal in the spinal cord?

Back

The central canal is a small, fluid-filled channel that runs longitudinally through the center of the spinal cord, containing cerebrospinal fluid (CSF) that helps protect and nourish the spinal cord.

Front

What is the function of the lateral gray horn in the spinal cord?

Back

The lateral gray horn contains autonomic motor neurons that are involved in the regulation of involuntary functions, such as heart rate and digestion.

Front

What is found in the lateral white column of the spinal cord?

Back

The lateral white column contains ascending and descending nerve tracts that carry sensory and motor information to and from the brain.

Front

What is the role of the posterior gray horn in the spinal cord?

Back

The posterior gray horn contains sensory neurons that receive and process sensory information from the body, such as pain and temperature.

Front

What is the posterior white column responsible for?

Back

The posterior white column contains ascending sensory pathways that transmit information about touch, proprioception, and vibration to the brain.

Front

What are the main components of the spinal cord?

Back

The spinal cord is composed of gray matter (containing neuron cell bodies) and white matter (containing myelinated axons), organized into horns and columns.

Front

How does the structure of the spinal cord relate to its function?

Back

The organization of gray and white matter in the spinal cord allows for efficient processing and transmission of sensory and motor information between the body and the brain.

Front

What is the significance of myelination in the spinal cord?

Back

Myelination increases the speed of nerve impulse conduction along axons, allowing for faster communication between neurons.

Front

What types of neurons are found in the spinal cord?

Back

The spinal cord contains sensory neurons, motor neurons, and interneurons, each playing a distinct role in processing and transmitting information.

Front

What is the role of interneurons in the spinal cord?

Back

Interneurons facilitate communication between sensory and motor neurons, playing a crucial role in reflexes and processing information.
