Sensory receptors are dendrites of sensory neurons specialized for receiving specific kinds of stimuli. Sensory receptors are classified by three methods Classification by receptor complexity: Free nerve endings are dendrites whose terminal ends have little or no physical specialization. A sensory receptor, or sense organ, is the Read More …

Cerebral Cortex – Anatomy, Types, Structure, Functions
The cerebral cortex is composed of a complex association of tightly packed neurons covering the outermost portion of the brain. It is the gray matter of the brain. Lying right under the meninges, the cerebral cortex divides into four lobes: Read More …
Cerebellum – Anatomy, Structure, Functions
The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements. It is also responsible for a number of functions including Read More …
Cerebellar Dysfunction – Causes, Symptoms, Treatment
Cerebellar dysfunction causes balance problems and gait disorders along with difficulties in coordination resulting in ataxia, uncoordinated movements, imbalance, speech problems(dysarthria), visual problems (nystagmus) and vertigo as a part of the vestibulocerebellar system. Cerebellar dysfunction causes balance problems and gait disorders along with difficulties Read More …
Cerebrum – Anatomy, Types, Structure, Functions
The cerebrum is the uppermost part of the brain. It contains two hemispheres split by a central fissure. The cerebrum itself contains the major lobes of the brain and is responsible for receiving and giving meaning to information from the sense organs, as well Read More …
Crossed Brainstem Syndromes – Causes, Symptoms, Treatment
Crossed Brainstem Syndromes/Brainstem stroke syndromes, also known as crossed brainstem syndromes, refer to a group of syndromes that occur secondary to lesions, most commonly infarcts, of the brainstem. A brainstem infarction (BSI) is a stroke that happens when blood cannot flow Read More …

Brainstem – Anatomy, Types, Tract, Functions
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain, the brainstem is composed of the midbrain, the pons, and the medulla oblongata. … Ten pairs of cranial nerves come from the brainstem. The brainstem (brain stem) is Read More …
Blood-Brain Barrier and Cerebrospinal Fluid
Blood-Brain Barrier and Cerebrospinal Fluid/The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces Read More …
