FIGURE 12.4 | Hairy Thin Skin of Scalp: Hair

Follicles and Surrounding Structures

This low-power photomicrograph illustrates a section of the thin skin of the
scalp. In the epidermis (1), the stratum corneum (1a), stratum granulosum
(1b), and stratum spinosum (1c) layers are thinner than the same layers in the
thick skin. In the dense irregular connective tissue of the dermis (4) are hair

follicles (3) and sebaceous glands (2, 5). An arrector pili muscle (6) extends
from the deep connective tissue sheath around the hair follicle (3) to the
connective tissue of the dermal papillary layer beneath the epidermis.
