nounlarge egg-shaped structures of grey matter that form the dorsal subdivision of the diencephalontype of:
Definition that contains thalamus
- fillet a bundle of sensory nerve fibers going to the thalamus
- amygdala an almond-shaped neural structure in the anterior part of the temporal lobe of the cerebrum; intimately connected with the hypothalamus and the hippocampus and the cingulate gyrus; as part of the limbic system it plays an important role in motivation and emotional behavior
- rh any of several hormones produced in the hypothalamus and carried by a vein to the anterior pituitary gland where they stimulate the release of anterior pituitary hormones; each of these hormones causes the anterior pituitary to secrete a specific hormone
- rf a substance produced by the hypothalamus that is capable of accelerating the secretion of a given hormone by the anterior pituitary gland
- brainstem the part of the brain continuous with the spinal cord and comprising the medulla oblongata and pons and midbrain and parts of the hypothalamus
- vasopressin hormone secreted by the posterior pituitary gland (trade name Pitressin) and also by nerve endings in the hypothalamus; affects blood pressure by stimulating capillary muscles and reduces urine flow by affecting reabsorption of water by kidney tubules
- striatum a striped mass of white and grey matter located in front of the thalamus in each cerebral hemisphere; consists of the caudate nucleus and the lenticular nucleus
- hypothalamic of or relating to the hypothalamus
- hypophyseal stalk the funnel-shaped stalk connecting the pituitary gland to the hypothalamus
- amygdaloid nucleus an almond-shaped neural structure in the anterior part of the temporal lobe of the cerebrum; intimately connected with the hypothalamus and the hippocampus and the cingulate gyrus; as part of the limbic system it plays an important role in motivation and emotional behavior
