Integumentary System

The integumentary system is made up of the skin, hair, and nails. Its main functions are protection, regulation, and sensation. The skin is the largest organ in the human body, and it contains a variety of receptors that sense touch, temperature, pressure, and pain. The Integumentary System infographic provides a colorful representation of the system that’s easy for students to read and understand.

Sensory receptors in the skin are important for perceiving the external environment. The density of these receptors depends heavily on the location on the body. Use Carolina® 2-Point Discriminators to help students explore varying pressure receptor densities at different points. The activity “Cutaneous 2-Point Discrimination” provides a quick, easy procedure to help students learn about some of the functions of their own integumentary systems.

Skin models provide greatly enlarged cross sections that make it easy to visualize the layers of the skin as well as the placement of sebaceous glands and sensory receptors. Prepared microscope slides of skin cross sections are also valuable in the study of the integumentary system. Pressure receptors aren’t the only kind of sensory receptor you can examine. The Carolina® Cutaneous Sensations Kit allows students to test for touch and temperature receptor density. As you wrap up your integumentary system unit, use this review as a study guide.

It Takes Guts to Teach A&P

Anatomy and physiology (A&P) is such a high-stakes endeavor for your students. All of them will be challenged some will excel, and many will struggle to master it– even though career goals and dreams are on the line.

Anatomy and Physiology: Human Organs

Take a deeper dive into the anatomy and physiology of specific organs and structures within the human body. Use our student-ready infographics to introduce each key body part. Encourage students to apply their knowledge of each system by investigating health-focused case studies related to each structure.

Selecting and Caring for Anatomical Models

Models are among the most traditional and useful items in a science educator’s toolbox. Whether your subject of study is leaf morphology, invertebrate zoology, general biology, or human anatomy, models are the perfect adjunct to texts and diagrams. They enable students to examine the finest structural details of an organism or its components in 3-dimensonal […]
