USMLE Step 1 ON-LINE PreTest: Anatomy, Histology and Cell Biology

If you are planning to prepare for the United States Medical Licensing Examination (USMLE) Step 1, then this On-line PreTest  is designed for you. Here, in one space, is a comprehensive review resource with over 600 examination type anatomy multiple-choice questions with referenced explanations of each answer.
This introduction provides specific information on the USMLE Step 1, information on question types, question-answering strategies, and various ways to use this On-line PreTest  .

Anatomy, Histology and Cell Biology: On-line PreTest  allows medical students to comprehensively and conveniently assess and review their knowledge of anatomy, histology, embryology, and cell biology. The 500 questions provided here in have been written with the goal to parallel the topics, format, and degree of difficulty of the questions found in the United States Medical Licensing Examination (USMLE) Step 1. Although the main emphasis of this on-line PreTest is preparation for Step 1, the On-line PreTest   will be very beneficial for medical students during their preclinical courses whether they are enrolled in a medical school with a problem-based, traditional, or integrated curriculum. This On-line PreTest   focuses on an interdisciplinary approach incorporating numerous clinical scenarios so it will also be extremely valuable for students preparing for USMLE Step 2 who need to review their anatomical knowledge. Practicing physicians who want to hone their basic science skills and supplement their knowledge base before USMLE Step 3 or recertification will also find this On-line PreTest   to be an outstanding resource for their review of the anatomical disciplines.

This On-line PreTest   is a comprehensive review of early embryology, cell biology, histology (tissue and organ biology), and human (gross) anatomy with some neuroanatomical topics reviewed in the High-Yield facts section. In keeping with the latest curricular changes in medical schools, as much as possible, questions integrate macroscopic and microscopic anatomy with cell biology, embryology, and neuroscience as well as physiology, biochemistry, and pathology This On-line PreTest   begins with early embryology, including gametogenesis, fertilization, implantation, the formation of the bilaminar and trilaminar embryo, and overviews of the embryonic and fetal periods. This first section is followed by a review of basic cell biology, with separate chapters on membranes, cytoplasm, intracellular trafficking, and the nucleus. There are questions included to review the basics of mitosis and meiosis as well as regulation of cell cycle events. Tissue biology is the third section of the On-line PreTest  , and it encompasses the tissues of the body: epithelium, connective tissue, specialized connective tissues (cartilage and bone), muscle, and nerve. Organ biology includes separate chapters on respiratory, integumentary (skin), digestive (tract and associated glands), endocrine, urinary, and male and female reproductive systems, as well as the eye and the ear. The topics in tissue and organ histology and cell biology include light and electron micrographs of appropriate structures that students should be able to identify The last section of the On-line PreTest   contains questions reviewing the basic concepts of regional anatomy of the head and neck, thorax, abdomen, pelvis, and extremities. For each section, appropriate x-rays, including MRIs, are included to assist the student in reviewing pertinent radiological aspects of the anatomy Where possible, information is integrated with development and histology of the organ system.

Each question in the On-line PreTest   is followed by five or more answer options to choose from. In each case, select the one best response to the question. Each answer is accompanied by a specific page reference to a text that provides background to the answer, and a short discussion of issues raised by the question and answer. A bibliography listing all the sources can be found following the last chapter.
