BIOS 251 Week 5 Case Study Assignment: Integumentary System (RATED A)

OL Lab 5: Integumentary system Learning Objectives: • Identify the tissue and cellular features of the skin. • Identify the structures associated with the skin. • Correlate the anatomical fe atures to its functions. • Identify the role of the skin in thermoregulation and wound healing. Part A: Anatomy of the skin I. Microscopic anatomy of the skin. Complete the table using the image provided: II. Gross anatomy of the skin. Complete the table using the image provided. Structure Function A Hair Protection, regulation of body temp, and facilitation of evaporation B Cutaneous Blood Vessel Transport oxygen and nutrients to skin while removing wastes C Arrector pili muscle Muscles contract all at once causing hair to stand up on skin D Sebaceous gland Produce and secrete sebum which lubricates skin to protect against friction E Merocrine Sweat gland Sweat cools the surface of skin and reduces body temp F Hair follicle Cavity or sav from hair origination G Hypodermis Made of connective tissue; for support, thermoregulation, and stored energy H Pancinian corpuscle End of sensory nerve that acts as a receptor for pressure and vibration I Epidermis Provides waterproof barrier and creates skin tone and regulates body temp J Papillary region Provides nutrients to produce keratinocytes K Reticular region Serves skin with strength and elasticity 00084L DfroemrmCoisurseH on 11-0 4C-2u0s2h2i0o9n:1s9:b28odGyMTfr-o0m5:00stress and strain Part B: Thermoregulation Use the diagram provided, to answer the questions. 1. Homeostatic regulatory mechanism involves atleast 3 independent components.Identify these components labeled as A, B, C in the diagram. A. Receptor B. Control Center C. Effectors 2. Describe in your own words the physiological events that would occur during this feedback mechanism. Thermoregulation is a form of negative feedback in maintaining homeostasis. When the body is cold then it will cause shivering, but with this you would only shiver due to muscles contracting to cause heat to warm you back up again. 3. Identify the condition that would occur due to increase in body temperature. The condition to occur is due to the increase in body temperature to hyperthermia. Hyperthermia happens when the bodys heat regulation becomes too much and gets overwhelmed causing ones internal temperature to increase. Part C: Skin Wound Healing- Anatomy TV Instructions: For this part of the lab, you will use Anatomy TV to watch an animation on skin wound healing. Please read the instructions before you begin. 1.
