The disorder characterized by repetitive seizures due to abnormal brain electrical activity is: MCQ with Answer and Explanation

Explanation:
The cerebellum, meaning 'little brain', is a highly folded structure located at the posterior base of the skull, beneath the occipital lobes of the cerebrum and behind the brainstem. While it does not initiate movement, its primary functions are to coordinate voluntary motor movements, ensure muscle synergy, maintain posture, and regulate balance and equilibrium. It receives sensory input from the spinal cord, vestibular system, and cerebral cortex, and fine-tunes motor output to ensure smooth, accurate movements. Damage to the cerebellum results in ataxia (clumsy, uncoordinated movements).

Explanation:
The choroid plexus, located in the ventricles of the brain, is a network of capillaries and ependymal cells that secretes cerebrospinal fluid (CSF). CSF cushions the brain, removes waste, and maintains chemical environment. Meninges are protective coverings, corpus callosum connects hemispheres, pineal secretes melatonin.

Explanation:
The glomerulus is a tuft of fenestrated capillaries enclosed by the Bowman's capsule in the renal corpuscle. Blood is filtered under high pressure through the capillary walls into the Bowman's space. The filtrate then passes into the nephron tubules. Glomerular filtration is the first step in urine formation.
