BIO 251 Lab 6 – Muscle Identification & Actions of Head, Neck, Trunk – 2025 Q&A (BIO251)

This illustrated exam preparation document for BIO 251 Lab 6: Human Anatomy & Physiology (2025/2026) contains a complete set of muscle names, locations, and functions relevant to lab exams on the head, neck, thorax, abdomen, and pelvic floor musculature. The content is formatted in an accurate Q&A style with visual pairings (illustrations not shown here), making it an effective tool for both memorization and practical identification. Topics include all major facial expression muscles (frontalis, orbicularis oculi/oris, zygomaticus major/minor, buccinator, risorius), mastication muscles (masseter, temporalis), neck and hyoid muscles (sternocleidomastoid, digastric, stylohyoid, thyrohyoid, omohyoid), and tongue movers (genioglossus, hyoglossus, styloglossus). It also covers thoracic and abdominal wall muscles such as the pectoralis major/minor, intercostals, diaphragm, rectus abdominis, obliques, and pelvic floor muscles like the levator ani and coccygeus. Ideal for students pursuing Biology, Pre-Med, Nursing, Kinesiology, or Allied Health Sciences, this lab resource aligns with human muscle system learning objectives and is well-suited for practical identification and functional understanding.
