The major collagen component of the basal lamina is
A. Type IV
B. Type XI
C. Type VII
D. Type VIII
All are true of the basement membrane zone (BMZ) except
A. A porous semipermeable filter
B. Provides structural support for the epidermis and holds the epidermis and dermis together
C. BMZ also helps to regulate growth, adhesion and apoptosis
D. Restricts movement of keratinocytes and fibroblasts
Acrosyringium is
A. Intradermal spiral duct of sweat gland
B. Composed of small polygonal cells with a central round nucleus
C. It is derived from dermal duct cells through mitosis
D. Cells with ample pink cytoplasm
Which is also called as sudoriferous glands
A. Apocrine glands
B. Sweat glands
C. Sebaceous gland
D. Meibomian glands
All are TRUE about Fordyce spots EXCEPT
A. Benign
B. Visible
C. Sweat glands
D. Found commonly on the lips
If the auriculotemporal nerve is damaged excess sweat can be produced in the rear of the cheek area just below the ear in response to stimuli that cause salivation. This is seen in
A. Fox-Fordyce disease
B. Frey’s Syndrome
C. Hidradenitis suppurativa
D. Bromhidrosis

| Conditions of SKIN | Pathology | Description | |
| 1 | Fox-Fordyce disease | Apocrine sweat glands become inflamed | Persistent, itchy rash |
| 2 | Frey’s Syndrome | Auriculotemporal nerve is damaged | Excess sweat in response to stimuli that cause salivation |
| 3 | Hidradenitis suppurativa | Skin and sweat glands become inflamed | Swollen lumps Most commonly affected- – Underarms – Under the breasts – Groin |
| 4 | Sudorrhea | – Hyperhidrosis – Polyhidrosis | Excessive sweating – pathological |
| 5 | Milaria rubra | Called as -Prickly heat. Milaria rubra is the rupture of sweat glands and migration of sweat to other tissues. | Hot environments – skin’s horny layer expand due to sweat retention, blocking the ducts of eccrine sweat glands. |
| 6 | Osmidrosis | Called as -Bromhidrosis. Osmohidrosis is excessive odor from apocrine sweat glands | Caused by changes in the apocrine gland structure rather than changes in the bacteria that acts on sweat. |
