Neurons & Neurotransmitters: Functions & Disorders MCQs are crucial for studying how the nervous system controls cognition, emotions, and behavior. In CSS Competitive Exams, this subject assesses the candidate’s familiarity with the neuron structure, the function of neurotransmitters, and their influence on psychological disorders. The human brain uses intricate neural networks to transmit signals, allowing processes such as learning, memory, emotions, and decision-making. Understanding this subject is most important for candidates preparing for CSS psychology MCQs, as it offers knowledge of biopsychology, neurophysiology, and neurological disorders.
Structure and Function of Neurons
Neurons are the fundamental building blocks of the nervous system, tasked with the transmission of electrical and chemical signals. They are made up of the cell body (soma), dendrites, axon, and synapses. Myelin sheath facilitates signal transmission, while action potentials allow for communication among neurons. The central nervous system (CNS) and peripheral nervous system (PNS) collaborate in controlling sensory and motor functions. In CSS Psychological Assessment MCQs, applicants can be questioned on types of neurons (sensory, motor, interneurons), neural communication, and the impact of damage to neural tracts.
Role of Neurotransmitters and Related Disorders
Neurotransmitters are chemical messengers that affect mood, cognition, and behavior. Dopamine controls motivation and pleasure, whereas serotonin impacts mood stability. Acetylcholine is vital for learning and memory, while GABA prevents excessive neural activity to minimize anxiety. Neurotransmitter imbalances can cause mental illnesses like depression (low serotonin), schizophrenia (too much dopamine), and Parkinson’s disease (lack of dopamine). In CSS Psychology MCQs, neurotransmitter functions, synaptic transmission, and the neurological underpinnings of mental diseases are questions that may be posed. Free flashcards and CSS psychology quizzes on neural functions help augment exam preparation and conceptual understanding in neuroscience and behavior.
