IB Sports, Exercise & Health Science Unit 1 – 2025/2026 Q&A | Skeletal System | Joint Types | Muscle Function

This document provides a complete set of Unit 1 exam questions and correct answers for the IB Sports, Exercise and Health Science (SEHS) course, specifically designed for Year 1 students in the 2025/2026 academic year. It focuses on foundational anatomical and physiological knowledge required in the IB Diploma Programme, covering core content areas of the skeletal system, joints, muscles, and movement terminology. Topics include: Axial vs. appendicular skeleton functions Anatomical directional terms (e.g., proximal, distal, anterior, posterior) Types of joints (fibrous, cartilaginous, synovial) and their subtypes (hinge, pivot, ball and socket, etc.) Types of muscle tissue (smooth, cardiac, skeletal) and associated contractions (concentric, eccentric, isometric, isokinetic) Joint articulation and movement patterns Muscle origin and insertion definitions Muscle fiber types (slow twitch vs. fast twitch) and performance relevance Structure and classification of bones (e.g., long bones) Major muscle groups and their locations (deltoid, gastrocnemius, trapezius, etc.) Vertebral column composition (cervical, thoracic, lumbar, sacral, coccyx) This resource is ideal for: IB Year 1 students enrolled in SEHS DP Sports Science candidates preparing for internal tests, quizzes, or mock exams Teachers looking to create or supplement unit assessments and revision guides Students pursuing pre-university qualifications in sports medicine, physiotherapy, or kinesiology The document is structured in a Q&A format, ideal for flashcard-based study, group revision, or individual practice. All answers are clear, concise, and accurate, matching IB exam standards and expectations.
