What does the internal medullary lamina do?
The layer of white matter that divides the gray matter of the thalamus into three parts: anterior, medial, and lateral.
What is external medullary lamina?
External medullary lamina – a thin band of fibers that separates the internal capsule and reticular thalamic nuclei from the remainder of the thalamic nuclear regions.
What are intralaminar nuclei?
The intralaminar nuclei are collections of neurons in the thalamus that are generally divided in two groups as follows: anterior (rostral) group. central medial nucleus. paracentral nucleus.
Is the pituitary gland part of the diencephalon?
The diencephalon is the region of the embryonic vertebrate neural tube that gives rise to anterior forebrain structures including the thalamus, hypothalamus, posterior portion of the pituitary gland, and the pineal gland. The diencephalon encloses a cavity called the third ventricle.
What is reticular nucleus?
nucleus of the thalamus that forms a sheet-like structure and makes up the outer covering of the thalamus. The reticular nucleus is the only thalamic nucleus that does not project to the cerebral cortex. Instead it primarily modulates the activity of other thalamic nuclei.
What is the main function of diencephalon?
The diencephalon is involved in many crucial bodily functions including coordinating with the endocrine system to release hormones, relaying sensory and motor signals to the cerebral cortex, and regulating circadian rhythms (the sleep wake cycle).
What is supraoptic and paraventricular nuclei?
The supraoptic and paraventricular hypothalamic nuclei are the principal sources of the neurohypophysial hormones, oxytocin and vasopressin. A third group of neurons projects outside the hypothalamus, in large measure to preautonomic and related brainstem nuclei, and to the spinal cord.
What hormone does the hypothalamus produce?
The hormones produced in the hypothalamus are corticotrophin-releasing hormone, dopamine, growth hormone-releasing hormone, somatostatin, gonadotrophin-releasing hormone and thyrotrophin-releasing hormone.
