Lacunar stroke is the hemorrhage of the internal capsule.
Hemorrhage of the internal capsule is called stroke explain what the internal capsule is and why a patient with hypertension high blood pressure is more likely subjected to stroke?
A hemorrhage of the internal capsule is called a stroke. The internal capsule is the area of the brain where many nerves are threaded. People with hypertension or high blood pressure are more likely to be subjected to a stroke because of the pressure on the internal capsule and arteries.
What is internal capsule and why it is given that name?
It is a broad lamina of white matter made up of projection fibres which pass to and from the cerebral cortex.It's called as "internal capsule" simply because it forms an internal (inner) capsule to the lentiform nucleus.
How striatum is related to fibers of internal capsule?
The striatum is a structure in the brain that is closely connected to the fibers of the internal capsule. The internal capsule contains important motor and sensory pathways that carry information to and from the cerebral cortex and the brainstem. Fibers from the cortex travel through the internal capsule to reach the striatum, forming a crucial pathway for communication between different regions of the brain involved in movement and control.
Which portion of the lentiform nucleus is closer to the internal capsule?
globus pallidus
What is the right internal capsule of the brain?
The internal capsule is a white matter structure in the brain that carries signals between the cerebral cortex and the brainstem. It is divided into anterior and posterior limbs, with the posterior limb containing fibers that control movement and sensation. Damage to the internal capsule can result in motor and sensory deficits.
What is the corpus striatum and how is it related to the fibers of the internal capsule?
The corpus striatum is a collection of caudate nuclei and the putamen portion of the lentiform nucleus. The crossing of the internal capsules between the diencephalon and the basal ganglia gives the corpus striatum its stripped appearance, hence its name corpus striatum, or "stripped body." The corpus striatum consists of the basal ganglia and the internal capsule, and it is related to the internal capsule by separating it from the putamin.
How does heating a capsule make it break open?
Heating a capsule causes the material to expand, increasing internal pressure, which can rupture the capsule walls due to the build-up of pressure from the trapped gases or liquids inside. This pressure may exceed the structural integrity of the capsule, leading to it breaking open.
What is the function of the Internal Capsule?
The internal capsule is a white matter structure in the brain that serves as a major pathway for communication between different regions of the brain. It carries motor and sensory fibers to and from the cerebral cortex, facilitating voluntary movement, sensory perception, and other functions.
Why there is only superficial sensation loss not deep sensation loss in internal capsule hemorrhage?
In internal capsule hemorrhage, superficial sensation loss occurs because the fibers carrying pain and temperature sensations (spinothalamic tract) are located more laterally, while deep sensation fibers (proprioception and vibratory sense) are more medially positioned. The hemorrhage often affects the lateral portion of the internal capsule, leading to a loss of superficial sensory modalities while sparing the deeper sensations. Additionally, the organization of the internal capsule means that lesions typically disrupt the pathways for superficial sensations before impacting deep sensation pathways.
Why does a brain hemorrhage within a region of the right internal capsule results in paralysis?
Internal capsule contains all the nerve fibres coming from motor area of brain. So hemorrhage result in paralysis of the oposite side of the body. As there is crossing of nerve fibres to oposite side.
What is Internal radiation therapy used on?
Internal radiation therapy is used for some cancers of the head, neck, thyroid, breast, female reproductive system, and prostate
