What are the Lentiform nuclei?
The lentiform nucleus, or lenticular nucleus, comprises the putamen and the globus pallidus within the basal ganglia. With the caudate nucleus, it forms the dorsal striatum. It is a large, lens-shaped mass of gray matter just lateral to the internal capsule.
What is the function of the basal nuclei?
Basal ganglia
| Definition | A group of subcortical nuclei that fine-tune the voluntary motor activity |
|---|---|
| Function | Planning and modulation of movement, memory, eye movements, reward processing, motivation |
What are the two types of brain aneurysms?
There are two types of brain aneurysms: saccular and fusiform.
What is the medical term for brain aneurysm?
The medical term for an aneurysm that develops inside the brain is an intracranial or cerebral aneurysm. Most brain aneurysms only cause noticeable symptoms if they burst (rupture).
What part of the brain is the lentiform nucleus in?
The lentiform nucleus is found lateral to the head of the caudate nucleus and thalamus. Anteriorly it is connected to the head of the caudate nucleus by gray matter. The lateral aspect of the lentiform nucleus is referred to as the putamen, and is closely related to the claustrum and the insula.
Who is prone to brain aneurysm?
Age. Your risk of developing a brain aneurysm increases as you get older, with most cases diagnosed in people over the age of 40. This may be because the walls of the blood vessels are weakened over time by the constant pressure of blood flowing through them.
What are the three common types of aneurysms?
There are three types of aneurysms: abdominal aortic, thoracic aortic, and cerebral. Abdominal aortic aneurysms, sometimes known as “Triple A,” are the most common aneurysms of the aorta – the large blood vessel that carries blood away from your heart and through your body.
Why is the caudate nucleus important?
These deep brain structures together largely control voluntary skeletal movement. The caudate nucleus functions not only in planning the execution of movement, but also in learning, memory, reward, motivation, emotion, and romantic interaction.
