What does telencephalon mean in anatomy?
telencephalon. / (ˌtɛlɛnˈsɛfəˌlɒn) / noun. the cerebrum together with related parts of the hypothalamus and the third ventricle.
Which part of the brain is called telencephalon?
The cerebrum, telencephalon or endbrain, is the largest part of the brain containing the cerebral cortex (of the two cerebral hemispheres), as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb.
Why is it called the telencephalon?
The word telencephalon comes from two Greek roots: telos, meaning ‘end,’ and enkephalos, meaning ‘brain. ‘ So, telencephalon literally means the ‘endbrain,’ and in two ways, it is.
What does Telencephalic mean?
tel·en·ceph·a·lon (tĕl′ĕn-sĕf′ə-lŏn′, -lən) The anterior portion of the forebrain, constituting the cerebral hemispheres and related parts. Also called endbrain.
Is the basal ganglia in the telencephalon?
The basal ganglia comprise a distributed set of brain structures in the telencephalon, diencephalon, and mesencephalon (Figure 4.1 and Table 1). The forebrain structures include the caudate nucleus, the putamen, the nucleus accumbens (or ventral striatum) and the globus pallidus.
What is telencephalon and diencephalon?
forebrain, also called prosencephalon, region of the developing vertebrate brain; it includes the telencephalon, which contains the cerebral hemispheres, and, under these, the diencephalon, which contains the thalamus, hypothalamus, epithalamus, and subthalamus.
What does the telencephalon turn into?
The swelling that forms at the farthest end of the neural tube is called the telencephalon (telencephalon is Greek for “far brain”). The telencephalon begins to expand into two symmetrical structures that sit alongside one another at the very end of the neural tube; these will become the cerebral hemispheres.
Is the frontal lobe in the telencephalon?
Parts of the telencephalon Frontal lobe – The frontal lobe is associated with personality, conscience (right/wrong/consequences), planning and is the source of inhibitions. Temporal lobe – Auditory and language processing occurs in the temporal lobe; about 90\% on the left side.
What develops from the telencephalon?
From the telencephalon derive the cerebral cortex, basal ganglia, hippocampal formation, amygdala and olfactory bulb. From the diencephalon the thalamus and surrounding nuclei, hypothalamus, retina and optic nerve. The mesencephalon gives rise to the midbrain structures, and the metencephalon the pons and cerebellum.
Why is the telencephalon important?
The telencephalon is too large an area of the brain to try to link it with a function or short list of functions. It plays a role in most of our brain activity and thus is more analogous to an entire division of the nervous system than to a particular delimited brain structure.
What does the telencephalon gives rise to?
The telencephalon gives rise to the cerebral hemispheres; the diencephalon gives rise to the thalamus and hypothalamus.
Is the medulla in the telencephalon?
The metencephalon includes the pons and the cerebellum. The myelencephalon (spinal cord-like) includes the open and closed medulla, sensory and motor nuclei, projection of sensory and motor pathways, and some cranial nerve nuclei.
What is telencephalon in anatomy?
Definition of telencephalon. : the anterior subdivision of the embryonic forebrain or the corresponding part of the adult forebrain that includes the cerebral hemispheres and associated structures.
What is the meaning of telelon?
tel·en·ceph·a·lon | ˌte-len-ˈse-fə-ˌlän , -lən. : the anterior subdivision of the embryonic forebrain or the corresponding part of the adult forebrain that includes the cerebral hemispheres and associated structures.
What is the meaning of prosencephalic?
1. one of the two divisions of the prosencephalon, consisting of the cerebrum. 2. the anterior of the two vesicles formed by specialization of the prosencephalon in embryonic development. Called also endbrain. adj., adj telencephal´ic.
What is the anterior division of the prosencephalon?
The anterior division of the prosencephalon, which develops into the olfactory lobes, the cortex of the cerebral hemispheres, and the subcortical telencephalic nuclei, and the basal nuclei (ganglia), particularly the striatum and the amygdala. n. The anterior portion of the forebrain, constituting the cerebral hemispheres and related parts.
