The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body.
A 3D medical animation still shot showing different parts of the midbrain. 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.
Most famous parts of the brain highlighted in different colours The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate.
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]
The human cerebellum is located at the base of the brain, with the large mass of the cerebrum above it, and the portion of the brainstem called the pons in front of it. It is separated from the overlying cerebrum by a layer of tough dura mater called the cerebellar tentorium; all of its connections with other parts of the brain travel through the pons.
Proprioception – sense of the relative position of the parts of the body; Nociception – signals pain in response to nerve-damage or damage to tissue; Equilibrioception – sense of body movement, direction, acceleration, and balance Vestibular nerve (part of cranial nerve 8) – the main equilibrioception-related cranial nerve
The cerebral peduncles (In Latin, ped-means 'foot'.) are the two stalks that attach the cerebrum to the brainstem. [1] They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) tracts that run to and from the cerebrum from the pons.
