What is the striatum?

What is the striatum?

The striatum is the input module to the basal ganglia, a neuronal circuit necessary for voluntary movement control (Hikosaka et al., 2000). The striatum is composed of three nuclei: caudate, putamen, and ventral striatum. The latter contains the nucleus accumbens (NAcc).

What is Lentiform?

lentiform – convex on both sides; shaped like a lentil. biconvex, convexo-convex, lenticular. bulging, convex – curving or bulging outward.

What are the basal ganglia anatomy?

The term basal ganglia in the strictest sense refers to nuclei embedded deep in the brain hemispheres (striatum or caudate-putamen and globus pallidus), whereas related nuclei consist of structures located in the diencephalon (subthalamic nucleus), mesencephalon (substantia nigra), and pons (pedunculopontine nucleus).

What is right Lentiform?

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.

Is the basal ganglia in the telencephalon?

The basal ganglia comprise a distributed set of brain structures in the telencephalon, diencephalon, and mesencephalon (Figure 4.1 and Table 1). The forebrain structures include the caudate nucleus, the putamen, the nucleus accumbens (or ventral striatum) and the globus pallidus.

What is neostriatum and striatum?

Neostriatum is the name given to the caudate nucleus and the putamen (the putamen is the outer layer of the lentiform nucleus). The term is sometimes abbreviated to striatum, however, this should be distinguished from corpus striatum (which is the caudate nucleus in addition to the entirety of the lentiform nucleus).

What is the anatomy of the lung?

Anatomy of the Lung. The lungs are the major organs of the respiratory system, and are divided into sections, or lobes. The right lung has three lobes and is slightly larger than the left lung, which has two lobes. The lungs are separated by the mediastinum.

What is the costal surface of the lung?

The costal surface of the lung borders the ribs. The mediastinal surface faces the midline. Figure 22.2.1 Gross Anatomy of the Lungs. Each lung is composed of smaller units called lobes. Fissures separate these lobes from each other. The right lung consists of three lobes: the superior, middle, and inferior lobes.

What is the root of the lung?

HILUM It is a large depressed area that lies near the centre of the medial surface. Various structures enter and leave the lung via its root. ROOT OF THE LUNG The root is enclosed in a short tubular sheet of pleura that joins the pulmonary and mediastinal parts of pleura . It extends inferiorly as a narrow fold -The pulmonary ligament.
