Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.

This resource looks at several aspects of the immune system including:

The non-specific immune response
Specific immune response and antigen recognition
T cells and B cells
Autoimmune disease and allergic responses
Monoclonal antibodies
Long term immunity and vaccination

The term 'implantation' is often used to describe the attachment of the placental membranes to the endometrium in most animals. True implantation is a phenomenon in rodents and humans in which the conceptus 'buries' itself in the uterine endometrium. The conceptus temporarily disappears beneath the surface. In most other species, the conceptus does not truly implant, but attaches to the endometrial surface and remains in the luminal compartment.

Our second video on epithelial tissues. This video focuses on epithelial classification.

The concepts covered in this video include:
•Epithelial Classification
•Squamous Epithelial
•Cuboidal Epithelial
•Columnar Epithelial
•Simply and Stratified Epithelial
•Pseudostratified
•Transitional Epithelium

Anatomy and Physiology students must know some histology and there is no better place to start then by looking at the epithelial cells.

The integumentary system is an organ system that forms the protective covering of an animal and comprises the skin (including glands and their products), haircoat or feathers, scales, nails, hooves and horns. The integumentary system has a variety of functions; in animals, it serves to waterproof, cushion and protect the deeper tissues, excrete waste, regulate temperature and is the location of sensory receptors for pain, pressure and temperature. Generally mammalian skin is covered with hair and is termed hirsute skin. Where hair is absent, it is termed glabrous skin.

Anatomy & Physiology continues with a look at your biggest organ - your skin.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"The growing number of studies linking repetitive head trauma to abnormal brain function is concerning for today’s athletes and their families. Perhaps nowhere more so than in American football. But while researchers have explored the effects of head impacts from high school to the pros, they haven’t ventured as deeply into the effects for youth players—or how head impacts happen in the first place. That’s crucial, because players under the age of 14 account for more than 70% of the 5 million American athletes who play football. Now, a new study takes a close look at whether youth players intentionally lower their head when going for a hard hit. Broken down by session type, player position, and ball possession, the findings offer support for modifying rules and training in an effort to minimize head injuries among youth players. Using specially equipped helmets and video footage, the authors of the study collected data on more than 68 youth football players over 153 games and practices..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

These are interactive activities that are based on the OpenStax textbook on Anatomy and Physiology. The majority of definitions have been incorporated into dialogue cards. And the majority of diagrams have been made into interative drag and drop with MCQ and other question types.

Short Description:
This "textbook" is interactive, meaning that although each chapter has text, they also have interactive HTML5 content, such as quizzes, simulations, interactive videos, and images with clickable hotspots. Students receive instant feedback when they complete the interactive content, and therefore, can learn and check their understanding all in one place. The first unit introduces students to the nature of science, including scientific controversies, and information literacy, including how to analyze literature and identify stakeholders. Unit 2 is organismal biology, including carbon cycling and population growth, and unit 3 is molecular biology with a focus on gene expression.

Long Description:

Students receive instant feedback when they complete the interactive content, and therefore, can learn and check their understanding all in one place. I still consider this textbook to be fairly text-heavy and will continue to make it even more interactive content!

The image on the cover represents the creation of this book. I pulled most of the content from open resources, modified them, added questions, and now offer them for you to use!

I chose the content to align with two courses that I teach: environmental and organismal applications and biomedical applications. Unit 1 introduces students to science, which both courses use. Unit 2 covers content necessary for understanding conservation implications (the underlying theme of the course is de-extinction), and Unit 3 focuses on proteins so that students can understand the implications of modifying DNA (the underlying theme is CRISPR).

Please use this book as you see fit for your classes. I look forward to hearing how to make this book even more useful in the future!

The intermediate mesoderm exists as a strip of tissue between the lateral plate mesoderm and somites. It gives rise to the urinary system and some parts of the reproductive system. Kidney development includes three forms: Pronephros, Mesonephros, and Metanephros. Mammals develop all three, and continue to use the metanephros in adult life. More primitive animals have only the first one or two.

Sexual differentiaton by default follows a pathways for development of female internal and external genitalia, requiring no active intervention. Endocrine activity of the testes, production of Androgens by Leydig cells and Mullerian Inhibiting hormone (MIH) by Sertoli cells, is required for sexual differentiation to be diverted down the male genitalia development pathway.

This is a worksheet to accompany the "Introducing the Skeletal System" video, based on Chapter 6 of the OpenStax A&P textbook.
