Anatomy Of The Thalamus

The thalamus translates neural impulses from various receptors to the cerebral cortex. Anatomy of the thalamus.

Thalamus

In the rostral part of the thalamus the internal medullary lamina splits to form a partial capsule around the anterior nuclear group.

Anatomy of the thalamus. The thalamus has four surfaces medial lateral superior and inferior surface and it has two ends or poles anterior and posterior. In addition to the tracts mentioned above. Nuclei in a given pole or surface regulate specific functions or processing of sensory information and maintain particular connections with parts of the nervous and limbic system.

The posterior end of the thalamus is expanded to form the pulvinar. The external lamina covers the lateral surface and the internal lamina divides the nuclei into anterior medial and lateral groups. The thalamus is a limbic system structure and it connects areas of the cerebral cortex that are involved in sensory perception and movement with other parts of the brain and spinal cord that also have a role in sensation and movement.

The anterior end of the thalamus is rounded and narrow which forms the posterior boundary. The thalamus separating it into medial and lateral nuclear masses. As a regulator of sensory information the thalamus also controls sleep and awake states of consciousness.

The lateral mass contains the lateral nuclear group and the ventral nuclear group. The medial mass consists of the medial nuclear group. Anatomy of the thalamus the thalamus has two ends the anterior and posterior poles and four surfaces.

The thalamus is made up of two symmetrical structures formed from the diencephalon. The medial surface. The thalamus lies at the core of the diencephalon.

Medial lateral superior and inferior. Thalamus anatomy the thalamus a paired structure walnut sized shaped of grey matter found in the forebrain that is superior to the midbrain roughly the middle of the brain. Thalamus plural thalami either of a pair of large ovoid organs that form most of the lateral walls of the third ventricle of the brain.

The inferior surface of the thalamus is continuous with the tegmentum of the midbrain. In addition to being divided into anterior. There are areas of white matter in the thalamus including the stratum zonale that covers the dorsal surface and the external and internal medullary laminae.
