Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.

BAHHHHHH! Did I scare you? What exactly happens when we get scared? How does our brain make our body react? Just what are Neurotransmitters? In this episode of Crash Course Psychology, Hank takes us to the simplest part of the complex system of our brains and nervous systems: the neuron.

During the last couple of decades two new remarkably successful principles for diabetes therapy have appeared and are now used worldwide. These are incretin based therapy and surgical therapy. These two are at some extent linked together and in this lecture we’ll provide an introduction to these two principles for diabetes therapy.

In this presentation we’ll talk about the effects of GLP-1 (Glucagon Like Peptide 1), GLP-1 has important actions on gastrointestinal secretion and motility, and it acts to inhibit appetite and food intake. In continuation of the effects of GLP-1, we’ll talk about GLP-1, GIP, lipids, proteins, and dipeptidyl peptidase-4.

This presentation talks about intravenously GLP-1 infusion to patients with type 2 diabetes. The GLP-1 infusion is capable of restoring fasting glucose concentrations during the night time and can nearly normalize the meal-induced glucose excursions after meal ingestion. GLP-1 has many attractive actions regarding diabetes type 2 treatment, which is the theme of this presentation.

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 physiological effects of melatonin are far reaching, from acting as an neuroprotective agent to regulating circadian rhythms and sleep cycles. An imbalance of this hormone has even been linked to neurodegenerative diseases such as Parkinson’s, Alzheimer’s, and Huntington’s. The precise molecular mechanism by which melatonin exerts these effects, however, remains a mystery. To shed light on this process, a team of researchers has developed a melatonin-like compound that is unable to penetrate the cell membrane and binds only to cell-surface receptors. Melatonin’s physiological effects on the brain are controlled by the lock-and-key-like properties of this hormone and its receptors. When melatonin binds to its corresponding receptor, a biochemical signal is sent into the cell. But recent data suggests that this interaction may also occur inside the cell, itself. Specifically, on mitochondria within brain cells..."

The Endocrine Sequence teaches the basic principles of hormone secretion and action and the clinical disorders which result from abnormalities of hormonal activity. Students are expected to be familiar with the functions of the endocrine glands, the structure, secretion and action of the important hormones, and the major clinical endocrine disorders. Emphasis will be placed on understanding pathophysiology and being able to use general principles in endocrine phsyiology (e.g. negative feedback) or in the management of endocrine disorders (e.g., insulin management) in consideration of specific circumstances and clinical cases.

In this activity, students are divided into a group of hormones and a group of receptors. The hormones have to find their matching receptors, and the pair, once matched, perform a given action. This activity helps students learn about the specificity of hormone-receptor interactions within the endocrine system.

This animation describes the formation of endocrine glands starting with the mitosis of mesenchymal tissues, eventually leading to the formation of the secretory portion of the gland by differentiation.

Comprised of a group of duct-less glands with limited or no anatomical contact with each other, the endocrine system integrates and controls metabolic activity through the secretion of hormones into the vascular system. These hormones may have their effects on tissues and organs far from where they were produced.

"The balance between hunger and satiety plays a key role in metabolic health. Specifically, disrupted appetite can lead to eating disorders or obesity. Appetite control is influenced by a complex web of factors - including our gut microbiota. Gut microbiota influence appetite through a variety of mechanisms, including regulating appetite-related hormones such as leptin, ghrelin, and insulin, influencing the immune system and acting directly on hypothalamic neurons. Recently, there has been interest in exploring the gut-microbiota-brain axis in several research fields. Some research has suggested that the gut microbiota can regulate host body weight and even psychiatric disorders, but the effects of gut microbiome interventions have been inconsistent and require more research. Overall, there are many links between gut microbiota and host appetite, but the interaction is complicated by many outside variables, and the precise mechanisms have yet to be fully deciphered..."

In this video we're going to learn about how the concentration of hormones in our blood is regulated. By Ryan Patton.

This text been designed for an undergraduate human anatomy and physiology course at a medium sized public university. This text has been modified from the original OpenStax text to encourage more active reading for an early undergraduate student taking the first semester of a year-long human anatomy and physiology course sequence. This text has been targeted to our student population, consisting primarily of first semester pre-nursing and kinesiology majors at a university with a high proportion of first generation and PELL-eligible students who benefit from lower barriers to entry into the field. Therefore, freely-available and differently presented text can be beneficial to this student population. This version was designed with the intention of distributing it section by section through a learning management system. If this mode of distribution is used, connection to an assessment tool could be utilized. Systems covered include skeletal, muscular, cardiovascular, respiratory, and nervous.

As this text reorganizes and modifies an OpenStax’s Anatomy and Physiology 2e (see related resources link below), chapter numbers and chapter section numbers from the original have been preserved in this document. Material supplemented from other sources is cited within the text.

Course connections: Undergraduate courses aimed towards freshmen or sophomore, including Anatomy and Physiology, Introduction to Anatomy and Physiology, Physiology, Introduction to Physiology, Human Biology or similar with a human focus.

The Your Changing Body Student Edition book is one of ten volumes making up the Human Biology curriculum, an interdisciplinary and inquiry-based approach to the study of life science.
