Basal Ganglia and Cerebellum is part of the Central Nervous System section of Physiology. Practise 24 exam-style MCQs for NEET PG, FMGE, INI-CET and NEET SS, each with the correct answer and a detailed explanation.
Granule cells as the cerebellum's only excitatory neurons, feed-forward inhibition onto Purkinje cells and the striatum as basal ganglia input headline these Basal Ganglia and Cerebellum MCQs, which test Parkinson, Huntington and Wilson disease as high-yield NEET PG material.
Granule cells Only excitatory cell of cerebellum Use glutamate as neurotr ans mitter Forms parallel fibers Reference: Ganong, 25th edition page no.248
Decerebrate rigidity is due to exaggerated alpha motor neuron discharge. It is because of this that decerebrate rigidity is also called alpha rigidity Reference: Ganong, 25th edition page no.242
Voluntary movements are initiated at motor cortex Reference: Ganong, 25th edition page no 237
Feed forward inhibition - seen in cerebellum Stellate, basket and Golgi cells inhibit purkinje cells by feed forward inhibition Reference: Ganong, 25 th edition page no.248
Caudate and Putamen Collectively called as striatum They are the major input nuclei of striatum The neurons seen here are called as medium spiny neurons which stores the neurotr ans mitter GABA which is inhibitory Caudate nucleus has got a role in cognition (learning and memory) Reference: Ganong, 25th edition page no.243
Three major diseases of basal ganglia are, Parkinson disease (PD) Huntington disease (HD) Wilson disease (WD) Reference: Ganong, 25th edition page no.243
Ans. A. Procedural memory Procedural memory is a type of implicit memory that enables us to carry out commonly leaned tasks without consciously thinking about them, e.g., riding a bike, tying a shoe or washing dishes. Procedural memory likely uses a different part of brain than episodic memory - with brain injury you can lose one’s ability without losing other. That's why a person who has experienced amnesia and forget much about his or her personal life often retains procedural memory i.e., how to drive a car or use a fork etc. Striatum (a part of basal ganglia) is responsible for procedure memory.
Ventral anterior and ventral lateral nuclei Concerned with motor functions Receive input from basal ganglia and cerebellum Project to the motor cortex Reference: Ganong, 25th edition page no.269
Granule cells as the cerebellum's only excitatory neurons, feed-forward inhibition onto Purkinje cells and the striatum as basal ganglia input headline these Basal Ganglia and Cerebellum MCQs, which test Parkinson, Huntington and Wilson disease as high-yield NEET PG material.
MedLadder includes 24 curated MCQs for Basal Ganglia and Cerebellum under Physiology (Central Nervous System), covering NEET PG, FMGE, INI-CET and NEET SS preparation.
