Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Classify the different types of joints on the basis of structureExplain the role of joints in skeletal movement

This design course targets the solution of clinical problems by use of implants and other medical devices. Topics include the systematic use of cell-matrix control volumes; the role of stress analysis in the design process; anatomic fit, shape and size of implants; selection of biomaterials; instrumentation for surgical implantation procedures; preclinical testing for safety and efficacy, including risk/benefit ratio assessment evaluation of clinical performance and design of clinical trials. Student project materials are drawn from orthopedic devices, soft tissue implants, artificial organs, and dental implants.

The applet in this section allows you see how probabilities are determined from the exponential distribution. The user determines the mean of the distribution and the limits of probability. Three different probability expressions are available.

Students design and build a mechanical arm that lifts and moves an empty 12-ounce soda can using hydraulics for power. Small design teams (1-2 students each) design and build a single axis for use in the completed mechanical arm. One team designs and builds the grasping hand, another team the lifting arm, and a third team the rotation base. The three groups must work to communicate effectively through written and verbal communication and sketches.

"Synovitis is one of the most common and serious musculoskeletal diseases in horses, causing osteoarthritis and lameness. While available pharmaceutical treatments can reduce joint pain and inflammation, they are expensive and unable to prevent disease progression. Recently, researchers have started looking toward fibroblast-like synoviocytes (FLS) for the development of new treatment options. FLS are cells that produce lubricating proteins to protect cartilage from injury, But they lose their protective features and begin to produce inflammatory chemicals in horses with synovitis and ultimately cause the failure of the FLS mitochondrial machinery, cell death, and joint degeneration. A team of researchers thus transferred healthy mitochondria from immune cells into FLS to determine whether doing so could restore FLS function. They found decreases in cell proliferation and death after mitochondrial transfer as well as a reduction in the production of inflammatory proteins..."

The applets in this section allow users to see how probabilities and quantiles are determined from a Normal distribution. For calculating probabilities, set the mean, variance, and limits; for calculating quantiles, set the mean, variance, and probability.

"Tears to the anterior cruciate ligament typically require surgical reconstruction But the operation can cause muscle weakness and doesn’t always restore proprioception or joint kinematics A new biologic augmentation technique may overcome these limitations The technique employs intra-ligamentous and intra-articular infiltration of bone marrow aspirate and platelet-rich plasma to regenerate ACL tears When used in athletes with symptomatic partial ACL injuries the treatment restored both the structure and function of the ligament with fewer complications and a faster recovery than traditional surgery Although a larger cohort must still be tested the results show the potential of biologic augmentation for ACL repair Dallo, et al.

Students generally do not know the complexity that goes into building and programming a robotic arm. In actuality, creating such an arm comes from a design that involves mechanical, electrical, and computer science engineers. This activity allows students to control a robotic arm from both a machine's and a computer science engineer's perspective by letting them perform a simple task with a few entertaining instructions and constraints.
