400868 Human Anatomy and Physiology 1 Practical 2: The Integumentary System, Tissues and Histology Introduction For this activity you will be using charts, posters, models and cadaveric specimens in the anatomy lab. You may want to bring your textbook, lecture slides and atlas for reference. These practicals will be most beneficial to you if you read through these notes prior to class and attempt the short answer questions. Topics covered: 1. Tissue Structure and Function 2. The Integumentary System 3. Histology Objectives - Recognise epithelial tissues from histological slides using the naming conventions (simple, stratified, cuboidal, squamous, columnar) and give examples of their body locations - Recognise different types of connective tissue and give examples of their body locations - Understand the different types of muscular tissue and give examples of their body locations - Understand the different types of nervous tissue and components of a neuron - Name the layers, cell types and functions of the integumentary system Complete before practical: - Read or listen to The Integumentary System, Tissues and Histology lecture (week 3) - Read these practical notes and attempt the short answer questions Blended learning activity: When available (on vUWS), OPAL 2 and PHIZ 2 will complement this practical. The Mastering A&P website has a great collection of images of cadaveric specimens and models on PAL 3.0 . 2017- 400868 Human Anatomy and Physiology 1 | Practical 2 1

1. Tissue Structure and Function There are four main tissue types in the body. Each tissue type has various specific cell types within it. The human body has around 200 different cell types that perform specific functions such as homeostasis, communication, protection, movement, etc. 1.a. Epithelial Tissue Epithelial tissues line the external body and the cavities and surfaces of blood vessels and organs throughout the body. Compare the epithelium on your forearm (keratinized stratified squamous epithelium with hair appendages) with the epithelium inside your lips (non- keratinized stratified squamous epithelium). Though they are both epithelia, they are very different because they serve different functions. Complete the following table: 1.b Connective Tissue 2017- 400868 Human Anatomy and Physiology 1 | Practical 2 3 Epithelial tissue Looks like Found in Functions to Simple cuboidal square Kidney tubules Ovary Exocrine glands Secrete Absorb Simple columnar Tall, thin GI tract Secrete mucus/acid Absorb nutrients Simple squamous pavement-like “fried egg” Kidneys Lungs, Blood vessels Filtration Secretion Absorption Stratified squamous Several layers, squamous; surface cells, flattened, deep cells metabolically active Non keratinized: tongue, oral mucosa, pharynx, , vagina, anus (rarer)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
