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:Describe the symptoms, potential causes, and treatment of several examples of nervous system disorders
Students are introduced to the circulatory system with an emphasis on the blood clotting process, including coagulation and the formation and degradation of polymers through their underlying atomic properties. They learn about the medical emergency of strokes the loss of brain function commonly due to blood clots including various causes and the different effects depending on the brain location, as well as blood clot removal devices designed by biomedical engineers.
When a pregnant woman doesn't take care of herself, you might expect her baby to suffer from birth defects or childhood illnesses. But what happens when her baby grows up? In this Science Update, you'll hear about a recent study that suggests that malnutrition in the womb can come back to haunt you well into adulthood.
What does the brain look like? As engineers, how can we look at neural networks without invasive surgery? In this activity, students design and build neuron models based on observations made while viewing neurons through a microscope. The models are used to explain how each structure of the neuron contributes to the overall function. Students share their models with younger students and explain what a neuron is, its function, and how engineers use their understanding of the neuron to make devices to activate neurons.
Following the steps of the engineering design process and acting as biomedical engineers, student teams use everyday materials to design and develop devices and approaches to unclog blood vessels. Through this open-ended design project, they learn about the circulatory system, biomedical engineering, and conditions that lead to heart attacks and strokes.
In this lesson on the brain's neural networks, students investigate the structure and function of the neuron. They discover ways in which engineers apply this knowledge to the development of devices that can activate neurons. After a review of the nervous system specifically its organs, tissue, and specialized cells, called neurons students learn about the parts of the neuron. They explore the cell body, dendrites, axon and axon terminal, and learn how these structures enable neurons to send messages. They learn about the connections between engineering and other fields of study, and the importance of research, as they complete the lesson tasks.
Students work as biomedical engineers to find liquid solutions that can clear away polyvinyl acetate polymer "blood clots" in model arteries (made of clear, flexible tubing). Teams create samples of the "blood clot" polymer with different concentrations to discover the concentration of the model clot and then test a variety of liquids to determine which most effectively breaks down the model blood clot. Students learn the importance of the testing phase in the engineering design process, because they are only given one chance to present the team's solution and apply it to the model blood clot.
This patient education program explains the rehabilitation options available for people who have had a stroke. Rehabilitation through physical therapy, speech therapy, and occupational therapy may be necessary to improve the functions of the body after a stroke. This is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.
Stroke is the third largest cause of death in the UK after heart disease and cancer. It is also the single leading cause of severe disability in the UK. Classification of stroke is crucial in planning treatment and is a good indication of prognosis
This Learning Object helps individuals understand how to make the diagnosis of stroke using the Oxford Stroke classification. It is suitable for any health care professionals involved in the management of stroke but especially doctors and medical students
* To develop an understanding of the different symptoms and signs seen in stroke
* To be able to classify the type of stroke using the Oxford Stroke classification
* To relate the clinical diagnosis to the likely anatomical lesion and pathology
* To understand the importance of the clinical classification in estimating prognosis
