BIOLOGY 2300 – Unit 1 Exam Review (2025/2026) | 250+ Verified Q&A | Anatomy Basics, Tissues, Integument, Muscles, Nervous System, Circulation

This all-in-one BIOLOGY 2300 Unit 1 exam review contains over 250 verified and exam-accurate questions and answers, covering foundational content critical for success in the 2025/2026 academic year. Presented in a high-yield, question-and-answer format, this guide provides thorough coverage of multiple core systems and is ideal for mastering terminology, understanding structural relationships, and preparing for both lab practicals and lecture-based exams. Key topics include: Anatomy Fundamentals: Microscopic vs. macroscopic anatomy, body planes, anatomical positions, directional terms, organ systems Tissue Types: Epithelial, connective, muscle, and nervous tissues—including structure, classification, and real-world examples Integumentary System: Layers of the skin (epidermis, dermis, hypodermis), burns (1st to 4th degree), glands, pigmentation, and sensory receptors Muscular System: Muscle types (skeletal, cardiac, smooth), layers of connective tissue (epimysium, perimysium, endomysium), neuromuscular junctions, and movement terminology (flexion, abduction, rotation, etc.) Nervous System: Central vs. peripheral nervous system, neuron structure, neuroglia (e.g., astrocytes, Schwann cells), and nerve signal transmission Cardiovascular & Lymphatic Systems: Blood vessels (arteries, veins, capillaries), circulation routes, blood components, and immune transport Imaging Techniques: CT, MRI (T1/T2), and ultrasound fundamentals Lab Prep: Histological image references (e.g., stratum layers, connective tissues, blood vessels) to support both theoretical and visual learning Perfect for students in fast-paced allied health, nursing, and pre-med tracks, this review document is ideal for both in-class exams and standardized assessments (TEAS, HESI, etc.). Relevant for: Courses: BIOLOGY 2300, Anatomy & Physiology I, Human Biology, Pre-Nursing Fundamentals, Health Science Core Students: Nursing students, Pre-med students, Biology majors, Physical Therapy and Occupational Therapy students, Allied Health students Keywords: anatomy, histology, epithelial tissue, connective tissue, muscle tissue, nervous tissue, skin layers, stratum basale, dermis, burns, glands, hair follicle, afferent receptors, skeletal muscle, cardiac muscle, smooth muscle, neuromuscular junction, anatomical position, body planes, directional terms, nervous system, neurons, Schwann cells, astrocytes, veins, arteries, blood vessels, capillaries, circulation, lymphatic system, MRI, CT, ultrasound, BIOLOGY 2300
