Study Notes
Organization of the Central Nervous System: Telencephalon and the Meninges
- Telencephalon is superior to the diencephalon and comprises the cerebral hemispheres, components of the basal ganglia, and the limbic system.
- The cerebral hemispheres are divided into lobes, including the frontal, parietal, temporal, and occipital lobes.
- The cerebral cortex is the outer layer of the cerebral hemispheres and is highly folded, with gyri and sulci.
- The cortex of each lobe has different sensory or motor functions, such as the primary motor cortex, somatosensory cortex, visual cortex, and motor speech area of Broca.
- The corpus callosum is a white matter tract that links the cerebral hemispheres.
- Subcortical structures within the telencephalon include brain nuclei and white matter tracts, which form important neural pathways like the basal ganglia and limbic system.
- The basal ganglia is involved in the control of posture and movement and is composed of interconnected nuclei, including the lentiform nucleus, putamen, globus pallidus, corpus striatum, and caudate nucleus.
- The limbic system is involved in emotional processing, autonomic functions, learning, and memory, and includes structures like the cingulate cortex, fornix, thalamus, hippocampal formation, mammillary bodies, amygdala, and entorhinal cortex.
- The hippocampus is a major part of the hippocampal formation and is involved in spatial memory.
- The meninges surround the central nervous system and consist of three layers: dura mater, arachnoid mater, and pia mater.
- The dura mater is a dense fibrous membrane with two layers: the endosteal layer that lines the inside of the cranium and the meningeal layer that lines the brain and spinal cord.
- The dural venous sinuses are spaces formed between the endosteal and meningeal layers of the dura, which drain blood and cerebrospinal fluid from the brain.
