Quick Answer
This page provides solved notes, multiple-choice questions (MCQs), short-answer questions, and detailed long-answer questions for 10th Class Biology Chapter 5: Nervous System under the Federal Board (FBISE) curriculum. All material is aligned with the latest National Book Foundation (NBF) textbook for the 2026-2027 academic session, emphasizing Student Learning Outcomes (SLO) such as the central nervous system, neurons, nerve impulses, reflex actions, and the endocrine glands.
Chapter Overview
Chapter 5, 'Nervous System', covers the physiology of nervous and chemical coordination in humans. Students explore the role of coordination and the structural components of the human nervous system. This includes the Central Nervous System (comprising the brain's subdivisions—forebrain, midbrain, and hindbrain—and the spinal cord) and the Peripheral Nervous System, which connects the body organs to the coordinator.
The chapter discusses the structure of a neuron and its types (sensory, relay, and motor neurons). It details how coordination works: starting with a stimulus, the generation of nerve impulses (explaining resting potential and action potential), transmission across synapses via neurotransmitters, and the rapid path of reflex actions.
Additionally, the chapter covers the human Endocrine System as the chemical coordinator. Students will study major endocrine glands, such as the pituitary, thyroid, parathyroid, pancreas, and adrenal glands, along with their hormone secretions and functions. Conceptual clarity on impulse transmission and chemical feedbacks is critical for scoring high in the FBISE board exams.
