BIOS 251 Week 5 Lab; Integumentary System Structure & Functions Overview

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 features to its functions. Identify the role of the skin in thermoregulation and wound healing. Part A: Anatomy of the skin Microscopic anatomy of the skin.

B Stratum Granulosum Prevents fluid loss. C Stratum Spinosum Strength and flexibility of the skin D Stratum Basale Generation of cells on the epidermis. E Basement Membrane Supports structure, separates tissues, and protect them. F Sensory Nerve Detect and transmit information to the Central Nervous System (CNS). G Dermis Support and protect the skin and the deeper layers. Aide in sensation and thermoregulation. H Langerhans Cell Fighting skin infections by taking up and processing microbial antigens. I Merkel Cell Touch receptors of the skin. J Keratinocyte Protects the body from injury, infection, and any other harmful factors. K Melanocyte Produces melanin and it’s a pigment that gives hair and skin their color. Protects skin from damage caused by UV radiation.

Structure Function A Hair Protective barrier, help regulate body temperature, and acting as a sensory antenna. B Cutaneous Blood Vessels Help regulates body temperature and provide nutrients to the skin. C Arrector Pili Muscle Creates goosebumps and helps in thermoregulation. D Sebaceous Gland Protects the skin from drying out by producing sebum. E Merocrine/Eccrine Sweat Gland Regulates body temperature. F Hair Follicle Produce and sustain hair growth. G Hypodermis Fat storage. Provides insulation to regulate body temperature, cushioning from impact and anchor the skin to muscle and bones. Acts as a protective layer and energy reserve. H Pacinian Corpuscle Sensory receptor detecting deep pressure and high frequency vibrations within the skin. I Epidermal Ridges Fingerprints, enhancing grip or sense of touch when touching objects. J Papillary Region Helps regulate temperature, supply nutrients, and waste removal or remove cellular waste from the skin. K Reticular Region Provides strength, elasticity, and support. L Dermis Support and protect the skin and deeper layers. Helps
