BIO 251 – Lab 3 Skeletal System (120 Questions) | Bone Markings, Appendicular & Axial Anatomy – 2025

This comprehensive and expert-verified lab document includes 120 labeled practice questions and answers for BIO 251 – Human Anatomy & Physiology Lab 3, focusing on the skeletal system. Covering both axial and appendicular bones, this guide is ideal for students preparing for lab practicals, bone model exams, or detailed anatomical identification tasks. The first portion begins with microscopic bone structure, including elements such as: Osteon Central canal Lacunae Canaliculi Osteocytes It then transitions into macroscopic bone identification and markings of both the upper and lower limbs. Key bones include: Clavicle, scapula, humerus, radius, ulna, carpals, metacarpals, phalanges Pelvic bones (ilium, ischium, pubis, sacrum, coccyx) Femur, tibia, fibula, patella, tarsals, metatarsals, phalanges Each bone is broken down into distinct anatomical landmarks, such as tubercles, condyles, processes, notches, and fossae. This is particularly useful for students who need to recognize bones on physical lab models, exams, or virtual anatomy platforms. Recommended for: Students in Anatomy & Physiology, Pre-Med, Nursing, Kinesiology, Physiotherapy, and Allied Health programs Learners who need strong foundational knowledge of the skeletal system Individuals preparing for lab tests, bone identification quizzes, or clinical anatomy assessments With precise terminology and structured formatting, this document ensures efficient memorization and mastery of human skeletal anatomy.
