What is metathalamus?
The metathalamus is a region of the thalamencephalon formed by the medial and lateral geniculate bodies bilaterally. It serves as an important relay nucleus in both the auditory and visual pathways.
What does the metathalamus consist of?
The metathalamus is composed of the medial and lateral geniculate bodies, or nuclei. Fibres of the optic nerve end in the lateral geniculate body, which consists of six cellular laminae, or layers, folded into a horseshoe configuration.
Where is the metathalamus located?
Metathalamus. The metathalamus consists of two oval eminences (the geniculate bodies) on the caudal surface of the diencephalon, just inferior to the caudal end of the dorsal thalamus. The lateral and medial geniculate bodies function as primary thalamic relay stations for the auditory and optic system, respectively.
Is also called Thalamencephalon?
Thalamencephalon (Latin: thalamencephalon), also called thalamic region (regio thalamica) or thalamic complex (complex thalamica) is a complex structure comprising thalamus (in the wider sense of the term thalamus, i.e. dorsal thalamus, or thalamus proper, plus subthalamus, or ventral thalamus) and several adjacent …
What does the word fornix mean?
arch
Definition of fornix : an anatomical arch or fold: such as. a : the junction where the conjunctiva lining the eyelid meets the conjunctiva overlying the sclera.
Do humans have fornix?
The fornix is part of the limbic system. While its exact function and importance in the physiology of the brain are still not entirely clear, it has been demonstrated in humans that surgical transection – the cutting of the fornix along its body – can cause memory loss.
Does the epithalamus produce CSF?
Caudal to the forebrain is the diencephalon, a region which contains the epithalamus, hypothalamus, thalamus and third ventricle. There are four cavities in the brain called ventricles; here cerebrospinal fluid (CSF) is produced and circulated by ependymal cells and the choroid plexuses.
