The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. [1] In the human brain the brainstem is composed of the midbrain , the pons , and the medulla oblongata . [ 1 ]
The brainstem includes the midbrain, the pons, and the medulla oblongata. Behind the brainstem is the cerebellum (Latin: little brain). [7] The cerebrum, brainstem, cerebellum, and spinal cord are covered by three membranes called meninges. The membranes are the tough dura mater; the middle arachnoid mater and the more delicate inner pia mater.
Neurophilosophy – some observations on this type of approach and localization of function; Receptor cell – cells that sense external stimuli and conducted that information to the brain; Multisensory integration – organization of sensation from one's own body and the environment into usable functional outputs; Lateralization of brain function
Brainstem (dorsal view) A:Thalamus B:Midbrain C:Pons D:Medulla oblongata 7 and 8 are the four colliculi. The midbrain is the shortest segment of the brainstem, measuring less than 2cm in length. It is situated mostly in the posterior cranial fossa, with its superior part extending above the tentorial notch. [2]
Pontine nuclei; Pontine cranial nerve nuclei. Chief or pontine nucleus of the trigeminal nerve sensory nucleus (V); Motor nucleus for the trigeminal nerve (V); Abducens nucleus (VI) ...
It is the part of the brainstem situated between the midbrain and the medulla oblongata. [3] [4] The horizontal medullopontine sulcus demarcates the boundary between the pons and medulla oblongata on the ventral aspect of the brainstem, and the roots of cranial nerves VI/VII/VIII emerge from the brainstem along this groove. [5]
The reticular formation is a set of interconnected nuclei in the brainstem that spans from the lower end of the medulla oblongata to the upper end of the midbrain. [2] The neurons of the reticular formation make up a complex set of neural networks in the core of the brainstem. [3]
The parafacial zone receives inputs mainly from three areas: the hypothalamus, the midbrain, and the pons and medulla. [9]From the hypothalamus, the PZ receives inputs from the hypothalamic area, zona incerta, and the parasubthalamic nucleus; while the zona incerta and parasubthalamic nucleus functions remain largely unknown, several of their functions have been proposed to deal with action ...
