Study Notes
Organisation of the Central Nervous System: Telencephalon and the Meninges
- The 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, consisting of gyri and sulci.
- Each lobe of the cortex 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 linking the cerebral hemispheres.
- The telencephalon also contains subcortical structures, including the basal ganglia, which are involved in the control of posture and movement.
- The basal ganglia consist of interconnected nuclei, including the caudate nucleus, putamen, and globus pallidus.
- The limbic system, which is involved in emotional processing, autonomic functions, learning, and memory, spans the telencephalon and diencephalon.
- Key components of the limbic system include the cingulate cortex, fornix, thalamus, hippocampal formation, mammillary bodies, amygdala, and entorhinal cortex.
- The meninges surround the central nervous system and consist of three layers: the dura mater, arachnoid mater, and pia mater.
- The dura mater is a dense fibrous membrane that has its own blood supply and sensory innervation.
- The arachnoid mater is a thin avascular translucent layer that forms the subarachnoid space, which contains cerebrospinal fluid and cerebral vessels.
