BIOS251 OL, Week 5 Lab
Name: Brooke Johnson
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
I. Microscopic anatomy of the skin. Complete the table using the image provided:
Structure Function
A Stratum Corneum Resists friction, protects rest of
skin from damage
B Stratum Granulosum Responsible for waterproof
properties of skin
C Stratum Spinosum Contains Langerhans cells,
epidermal dendritic cells and
melanin granules
D Stratum Basale New cells are produced here
E Basement Separates tissues and protects
Membrane from additional stress
F Sensory Nerve Touch receptors
G Dermis Elasticity and strength of the
skin
H Melanocyte Absorbes UV, partially
responsible for skin color
I Merkel Cell Slowly adapting touch receptor
J Keratinocyte Tough fibrous protein that
serves to protect the skin
K Langerhans Cell Recognizes foreign microbes
and destroys them
