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 ...
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.
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 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 ...
Scheme of the roof of the fourth ventricle. The hindbrain, rhombencephalon (shaped like a rhombus) or lower brain [1] is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla, pons, and cerebellum. Together they support vital bodily processes.
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 ...
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem ), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
7647. Anatomical terminology. [ edit on Wikidata] The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals. The center of the spinal cord is hollow and contains a structure called the central ...
