The term for a collection of blood trapped in the tissue of the brain is "hematoma." Specifically, when this occurs within the brain tissue, it is often referred to as a "cerebral hematoma." This condition can result from trauma or injury and may lead to increased pressure in the brain, potentially causing serious complications.

What is formed by a tight network of capillaries that protect the delicate tissue of the CNS?
The blood-brain barrier is formed by a tight network of capillaries that protect the delicate tissue of the central nervous system (CNS). This barrier regulates the entry of substances from the blood into the brain, helping to maintain the brain's microenvironment and protect it from potentially harmful substances.
What acts as a gatekeeper to certain substances from entering brain tissue?
The blood-brain barrier acts as a gatekeeper to certain substances from entering brain tissue. It is a protective membrane that separates the blood vessels in the brain from the surrounding fluid, preventing the passage of many harmful substances while allowing essential nutrients and oxygen to reach the brain. This barrier helps maintain the delicate balance required for optimal brain functioning.
Where is brain parenchyma?
Brain parenchyma refers to the functional tissue of the brain, which includes the neurons, glial cells, and blood vessels. It is found throughout the brain, including the cerebral cortex, cerebellum, and brainstem.
Which tissue has the most blood supply?
A vascular organ is one relating to, affecting, or consisting of a vessel or vessels, especially those that carry blood. The spleen is the most vascular organ in the human body.
What protects the CNS from harmful substances and pathogens by preventing passage of these substances from blood into the interstitial fluid of brain tissue?
The blood-brain barrier is a protective mechanism that regulates the passage of substances from the blood into the interstitial fluid of the brain tissue. It consists of specialized endothelial cells that line the capillaries in the brain, tight junctions between these cells, and other supporting cells like astrocytes. This barrier helps protect the central nervous system (CNS) from harmful substances and pathogens.
What is the medical term meaning a mass of blood in a tissue?
hematomaA mass of blood is called a HematomaHematomaHematoma
What dangers does the blood-brain barrier protect the brain from?
The blood-brain barrier prevents various substances that could be poisonous to brain tissue (toxins), as well as many agents of infection, from crossing from the blood stream into the brain tissue.
What is the medical term meaning the protective mechanism that blocks chemicals from entering brain tissue?
The blood brain barrier blocks chemicals from entering brain tissue.
What is the difference between a stroke and a subdural hematoma?
A stroke occurs when blood flow to the brain is disrupted, leading to cell death. A subdural hematoma, on the other hand, is a collection of blood between the brain and its outermost covering (the dura mater), often caused by head trauma. Both can lead to neurological symptoms, but a stroke is due to a blood vessel blockage or rupture in the brain, while a subdural hematoma is blood collecting outside the brain tissue.
How can inflammation of the brain cause the blood-brain barrier to malfunction?
Inflammation may cause the blood-brain barrier to become less effective at preventing the passage of toxic substances into brain tissue.
What is the medical term meaning death of brain tissue from loss of blood supply?
Avascular is the medical term meaning without blood vessels.
Which of these conditions can be defined as an area of swollen brain tissue mixed with blood from broken blood vessels?
contusion
Which of the meninges connects to the brain and supplies blood to the nerve tissue?
Pia Mater
How do Barbiturates affect the brain?
Barbiturates reduce the metabolic rate of brain tissue, as well as the cerebral blood flow
How does blood differ from tissue fluid?
the blood contains proteins as tissue is a plasmid for h2O for photsynethis in the carribean weather for red blood cells and thrush in the head of the brain plamid content.
What is the definition of brain tissue?
Brain tissue refers to the mass of nerve cells and supporting structures that make up the brain. It is composed of neurons, glial cells, blood vessels, and connective tissue, all working together to facilitate brain function. Brain tissue is responsible for processing information, controlling bodily functions, and regulating emotions and behavior.
What is formed by a tight network of capillaries that protect the delicate tissue of the CNS?
The blood-brain barrier is formed by a tight network of capillaries that protect the delicate tissue of the central nervous system (CNS). This barrier regulates the entry of substances from the blood into the brain, helping to maintain the brain's microenvironment and protect it from potentially harmful substances.
