The brainstem (or brain stem) is the stalk-like part of the brain that connects the forebrain (the cerebrum and diencephalon) with the spinal cord. [ 1] In the human brain, the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [ 1][ 2] The midbrain is continuous with the thalamus of the diencephalon through the ...
Medulla oblongata. The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem. [ 1] It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions, ranging from vomiting to sneezing. [ 2]
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.
Cortical areas: Limbic lobe. Orbitofrontal cortex: a region in the frontal lobe involved in the process of decision-making. Piriform cortex: part of the olfactory system. Entorhinal cortex: related to memory and associative components. Hippocampus and associated structures: play a central role in the consolidation of new memories.
Anatomical terms of neuroanatomy. [ edit on Wikidata] In neuroanatomy, the medullary pyramids are paired white matter structures of the brainstem 's medulla oblongata that contain motor fibers of the corticospinal and corticobulbar tracts – known together as the pyramidal tracts. The lower limit of the pyramids is marked when the fibers cross ...
The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...
The cerebrum is the largest part of the brain. Depending upon the position of the animal, it lies either in front or on top of the brainstem. In humans, the cerebrum is the largest and best-developed of the five major divisions of the brain. The cerebrum is made up of the two cerebral hemispheres and their cerebral cortices (the outer layers of ...
The cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci. In the human brain, it is between 2 and 3-4 mm. thick, [ 8] and makes up 40% of the brain's mass. [ 2] 90% of the cerebral cortex is the six-layered neocortex whilst the other 10% made up of three ...
