The brain and spinal cord, responsible for processing information and controlling body functions.

The network of nerves that connect the CNS to the rest of the body, carrying signals to and from the brain and spinal cord.

A technique that uses a series of X-ray images to create a detailed image of the inside of the body, showing bone and soft tissue.

A technique that uses strong magnetic fields and radio waves to create detailed images of the inside of the body, showing soft tissues and organs in high resolution.

A technique that uses a radioactive tracer to measure brain activity and blood flow.

A technique that combines MRI with measuring blood flow changes in the brain, showing areas of increased activity.

Specialized cells that transmit information throughout the nervous system.

Cells that support and protect neurons, providing structural support and nourishment.

A type of neural imaging that uses magnetic fields and radio waves to create images of the brain and other tissues.

A type of CT scan that uses contrast material (iodine) to enhance the visibility of certain tissues.

A type of CT scan that uses contrast material (iodine) to enhance the visibility of the spinal canal.

A type of neural imaging that uses X-rays to create images of the spinal canal.

A measure of the time it takes for the transverse magnetization of a tissue to decay to 37% of its original value. T2 is affected by the local environment of water molecules, including the presence of other molecules and the rate of diffusion.

A measure of the time it takes for the longitudinal magnetization of a tissue to recover to 63% of its original value. T1 is affected by factors like the presence of fat and water.

The area in the brain that receives visual information from the eyes. The visual signals are then sent to the occipital lobe for processing.

The receiving end of a neuron where synaptic signals are integrated to determine if an action potential is generated.

A specialized region at the base of the axon where action potentials are initiated.

The transmitting end of a neuron where neurotransmitters are released to signal other neurons.

Specialized proteins embedded in the neuronal membrane that allow specific ions to pass through, playing a crucial role in electrical signaling.

Active transport mechanisms that maintain the concentration gradients of ions across the neuronal membrane, essential for electrical signaling.

The process of transporting molecules and organelles within neurons, essential for maintaining their structure and function.

The movement of molecules and organelles from the soma to the axon terminal.

The movement of molecules and organelles from the axon terminal towards the soma.

A type of neuron that transmits information from sensory receptors to the central nervous system.

A type of neuron that transmits information from the central nervous system to muscles and glands.

Long, slender projections of neurons that transmit signals away from the cell body.

Short, branched projections of neurons that receive signals from other neurons.

A specialized junction where neurons communicate with each other or with target cells.

Protein filaments that form the cytoskeleton of neurons, providing structural support and facilitating transport.

A type of glial cell that forms myelin sheaths around axons in the central nervous system.

A type of glial cell that forms myelin sheaths around axons in the peripheral nervous system.

The process of generating myelin sheaths around axons, which increases the speed of nerve impulse conduction.

A neurodegenerative disease that affects the central nervous system, characterized by the destruction of myelin sheaths.

Areas of demyelination (loss of myelin sheath) in the white matter of the brain and spinal cord, appearing as gray, gelatinous plaques.

The outermost layer of the brain, responsible for higher cognitive functions, sensory perception, and voluntary movement.

The white matter region surrounding the ventricles of the brain, often affected in MS.

The white matter of the spinal cord, containing tracts that carry signals to and from the brain.

Symptoms of MS can vary widely depending on the location and extent of demyelination, leading to diverse neurological impairments.

A decrease in strength and mobility, often affecting one side of the body due to nerve damage.

The ability to sense vibration and position of body parts (joints, muscles, etc.).
