Question

B. Testing for density of sudoriferous glands Complete the wing table with your obras Body Area Rite the relative densities of the spots: None A few Many Antero-medial surface of palm Posterior surface of the hand 2. Based on the observations, what can you say about the distribution of sudoriferous glands in • Thick vs. thin skin • Hirsute vs. non-hirsute skin 3. What would happen if you had performed this experiment after exercising? MAKE THE CONNECTION 1. Why are many injections given in the hypodermis? 2. Permanent tattoos are made by injecting pigment into the skin. Into which part of the skin is the pigment injected? 3. The epidermis is composed of many layers of keratinized epithelial cells that act as a barrier to infection and to absorption of water through the skin. Cortisone is a steroid that is applied to the skin to reduce inflammation and acts on the cells within the dermis. Explain how cortisone can pass through the epidermis to reach the dermis.

Answer 1

A. TESTING FOR DENSITY OF SUDORIFEROUS GLANDS.

1. None A few Many

●Antero medial surface + - +++

of palm

●Posterior surface - +++ -

of the hand

2. Thin skin has less eccrine gland and more apocrine gland, which is reverse in case of thick skin.

3. Hirsute skin is hairy skin having more of apocrine gland as compared to non hirsute skin with eccrine gland.

MAKE THE CONNECTION.

1. Many injections are given in hypodermis because of its high vascularity and therefore absobs the drugs quickly.

2. Dermis.,just below the epidermis.

3. Cortisone is a lipid soluble steroid and that's how it can easily diffuse through the cell membrane of the epidermis to dermis.
