Neurons of the lamina terminalis project to the supraoptic nucleus and paraventricular nucleus to regulate the activity of vasopressin-secreting neurons. [9] In a situation of lowered blood volume, secretion of renin by the kidneys results in the production of angiotensin II , which stimulates receptors in the VOLT and subfornical organ to ...
The lamina terminalis is a thin layer that forms the median portion of the wall of the forebrain. It stretches from the interventricular foramen (foramen of Monro) to the recess at the base of the optic stalk (optic nerve) and contains the vascular organ of the lamina terminalis , which regulates the osmotic concentration of the blood.
Lamina VII: intermediomedial nucleus, intermediolateral nucleus, posterior thoracic nucleus in the thoracic and upper lumbar region [6] Lamina X: an area of grey matter – the grey commissure surrounding the central canal. This region also serves to connect the anterior and posterior grey columns. [3] Rexed never described this as lamina X but ...
The marginal nucleus of spinal cord, posteromarginal nucleus, or spinal lamina 1 (Rexed lamina 1) is located at the most dorsal aspect of the posterior grey column of the spinal cord. The neurons located here receive input primarily from Lissauer's tract and relay information related to pain and temperature sensation.
The nervous system derives its name from nerves, which are cylindrical bundles of fibers (the axons of neurons), that emanate from the brain and spinal cord, and branch repeatedly to innervate every part of the body. [5]
The nuclear lamina: a dense fiber network inside the nucleus of cells. [6] The lamina affixa: a layer of epithelium growing on the surface of the thalamus. The lamina of Drosophila is the most peripheral neuropil of the insect visual system. Lamina cribrosa with two different meanings. Osseous spiral lamina, a feature of the bony canal of the ...
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
The peripheral nervous system is divided into the somatic nervous system, and the autonomic nervous system.The somatic nervous system is under voluntary control, and transmits signals from the brain to end organs such as muscles.
