Bio 400 Exam Questions and Answers||A+ Solution guide(Verified) Study of external features and superficial anatomical markings related to deeper structures. - Answer- Surface Anatomy Study of superficial and internal features in a specific area (e.g., head, neck, trunk). - Answer- Regional Anatomy Study of anatomy based on the body's organ systems. - Answer- Systemic Anatomy Study of changes from conception to physical maturity. - Answer- Developmental Anatomy Histology - Answer- The study of tissues using microscopic techniques. The study of body functions carried out by anatomical structures. - Answer- Physiology The study of abnormal conditions in anatomical structures that may result in clinical diseases. - Answer- Pathology The study of structures visible to the naked eye. - Answer- Gross (Macroscopic) Anatomy The study of structures that require magnification to be seen. - Answer- Microscopic Anatomy Study of the internal structure of cells. - Answer- Cytology Study of tissues (groups of cells). - Answer- Histology Tissue Preparation - Answer- Involves removal, preservation (fixation), embedding, sectioning, and staining for microscopic examination. Epithelial Tissue - Answer- Sheets of cells that cover exposed surfaces and line internal cavities. Epithelia - Answer- Outer covering (e.g., skin surface). Glands - Answer- Secretory structures (e.g., salivary glands). Cellularity - Answer- Cells bound tightly with little intercellular space. Polarity - Answer- Has an apical (external) and basal (attachment) surface. Attachment - Answer- Bound to a basement membrane. Avascularity - Answer- No blood vessels; nutrients diffuse from underlying tissues. Layered Structure - Answer- Can be one or multiple layers. Regeneration - Answer- Continuously replaced by stem cell division. Protection - Answer- Shields surfaces from damage, dehydration, and pathogens. Permeability Control - Answer- Selective absorption and secretion. Sensation - Answer- Contains sensory receptors. Specialized Secretions - Answer- Includes hormones, mucus, and digestive enzymes. Simple Epithelium - Answer- One layer, for absorption/secretion. Stratified Epithelium - Answer- Multiple layers, for protection. Pseudostratified Ciliated Columnar - Answer- Appears layered but is not (e.g., respiratory tract). Transitional Epithelium - Answer- Stretches (e.g., bladder). Endocrine Glands - Answer- Release hormones into the bloodstream. Exocrine Glands - Answer- Release secretions through ducts onto epithelial surfaces. Connective Tissue - Answer- Provides structure, transport, and defense. Matrix - Answer- Combination of fibers and ground substance. Skeletal Muscle - Answer- Voluntary, striated, multinucleated. Cardiac Muscle - Answer- Involuntary, striated, single nucleus. Smooth Muscle - Answer- Involuntary, non-striated, single nucleus. Nervous Tissue - Answer- Conducts electrical impulses. Neurons - Answer- Transmit electrical signals. Neuroglia - Answer- Support and protect neurons.
