Stratum Papillare & Stratum Reticulare

A

Two Layers of the Dermis

20
Q

Stratum Papillare

A

Thin superficial layer interlocked with the epidermis

21
Q

22
Q

Stratum Reticulare

A

Thick layer of dense, irregular connective tissue

23
Q

Stratum Reticulare

A

24
Q

Dermis Extra Information

A

The dermis also contains vessels carrying blood and lymph, nerves and nerve endings, glands, and hair follicles. The dermis lies on the
subcutaneous (beneath the skin) tissue

25
Q

Subcutaneous Tissue (hypodermis)

A

not considered to be a layer of the skin, mostly composed of fatty or adipose tissue, plus some areolar tissue, the fibrous connective tissues referred to as superficial fascia is included in this layer

Q

Two Separate Structures of Hair

A

Follicle & Shaft

29
Q

Follicle Structure

A

the base is a bulb-like projection, called a papilla. Capillaries nourish the bulb. Inner and outer sheaths protect and mold the growing hair shaft surrounding the follicle. The inner sheath ends at the opening of the sebaceous gland, which secretes sebum that may pocket to cause benign lesions on the scalp. Muscles, called the arrector pili, attach to the outer sheath and cause the hair to stand up when they contract
