FAQs

What is the largest danger associated with a blood clot that's lodged in a cerebral artery? ›

When an artery is blocked, the brain cells (neurons) are unable to create ample energy. After some time, these cells stop working. Blockage for more than a few minutes is hazardous because the brain cells may die due to lack of supply of blood. Instant medical treatment is critical under such situations.

People with choroid plexus tumors may have hydrocephalus—increased pressure within the skull due to the production of too much CSF or blockage of its normal flow.

The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons.

If a blood clot blocks the arteries leading to part of the heart muscle, it will cause a heart attack. If it blocks an artery in the brain, it will cause a stroke. Symptoms therefore depend on where the blood clot has formed.

The drug tissue plasminogen activator (TPA) also helps to break up any clots that may form in the brain. Ischemia and reperfusion treatments can help remove clots and reduce post-treatment complications substantially. Exercise regularly, but do not strain yourself.

The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body. The brain is what controls all the body's functions. The spinal cord runs from the brain down through the back.

The frontal lobe, located behind the forehead, does much of the work of complex thinking, like planning, imagining, making decisions, and reasoning.

Rebalancing your nervous system means getting back to a state where you feel calm and centered. You can try practicing deep breathing exercises, spending time in nature, or taking short breaks during the day. Regular sleep, a balanced diet, and talking to someone you trust can also help.

The simplest form of behavior, called a reflex, involves impulse conduction over a few neurons. This path is called a reflex arc. A. Sensory or afferent neurons transmit impulses from sensory receptors to the spinal cord or brain.

Answer: Sensory neurons carry nerve impulses from sense organs and internal organs to the central nervous system. Motor neurons carry nerve impulses from the central nervous system to organs, glands, and muscles - the opposite direction.

What do neurons send messages through? ›

When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.

A thrombotic stroke occurs when a blood clot, called a thrombus, blocks an artery to the brain and stops blood flow. An embolic stroke occurs when a piece of plaque or thrombus travels from its original site and blocks an artery downstream. The material that has moved is called an embolus.

When this happens, the brain can be deprived of oxygen as it is cut off. This can cause damage to the brain cells and even lead to death. While some people may experience a mild episode of this event without any symptoms, others may go on to have more serious complications, including seizures or death.

Causes of cerebrovascular disease may include: Blood clot that spontaneously forms in a blood vessel in your brain. This is “thrombosis” and usually happens in areas where your blood vessel is narrow or irregular. Blood clot that travels to your brain from elsewhere in your body (embolism).

In some cases, a deep clot in a leg vein can break free and stick in a vessel in the lung. This can cause a blockage in the vessel called a pulmonary embolism. Pulmonary embolism can cause severe shortness of breath and even sudden death.
