Skin
Appendages -- epidermal derivatives such as hair follicles,
glands, etc. whose distribution, arrangement, and structural details
vary greatly in skin on different parts of the body.
Examine several hair follicles cut
transversely on these two slides (sample
1 and sample 2).
 In
the hair shaft itself, identify if possible the following structures
(not all layers may be evident, depending on the plane of section).

Examine hair follicles cut
longitudinally on these slides (sample
1 and sample 2), and again,
identify as
many layers as possible. 
Next identify
- Sebaceous glands,
pictured to the right, and
- Arrector pili muscle
associated with hair follicles.
