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 Primary barrier between the
body and environment
B Stratum Granulosum Helps to form waterproof
barrier to prevent fluid loss
C Stratum Spinosum Partly responsible for skins
strength and flexibility
D Stratum Basale Proliferation and attachment of
epidermis to dermis
E Basement Membrane Form anatomical barrier, relay important
signals, and differentiation and
maintenance of tissue
F Sensory Neuron Transmits impulses from
receptor, eye, ear, spinal cord,
or brain
G Dermis Cushion the body from stress
and elasticity of skin
H Langerhans Cell Ability to migrate from
epidermis to lymph nodes
I Merkel Cell Proper neural encoding of light
touch stimuli
J Keratinocyte Produce keratin, arise stratum
absale, undergo continuous
mitosis
K Melanocyte Produce melanin

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 Transport oxygen and
Vessel 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 Sweat cools the surface of
gland 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
