at high power of magnification focus on the layer of the epidermis that appears purple beneath the most superficial layer. what are the purple-stained apparent particles that occur in the cells of this layer examined on an h&e slide of thick skin
Functions of the Integument • Protection from the environment-the skin is the superficial surface of the body _-secretions from sweat glands in the skin cool the body down Storage of lipids- Vitamin D synthesis-stimulates bone growth Provides sensory info-sensory receptors located in the skin Layers of the epidermis-Stratified squamous epithelia Stratum basale (germinativum)-attached to contains stem cells & melanocytes Stratum spinosum-, stem melanocytes cells develop into keratinocytes, Stratum granulosum-keratinization begins, adding membrane proteins, cells thin, - die Stratum lucidum-only in...

Q46. Which organ system is responsible for fighting pathogens? A) Lymphatic B) Muscular C) Endocrine D) Urinary Q49. Bone is a type of: A) Connective tissue proper B) Fluid connective tissue C) Supporting connective tissue D) Non-calcified cartilage Q47. The stratum lucidum is found only in: A) Epidermis of thin skin B) Epidermis of thick skin C) Dermis of thin skin D) Dermis of thick skin Q50.

Dense Irregular Connective Tissue 1 Examine a slide of thick skin under low power. In Activity 5.1, you observed the epidermis. Locate this layer again and identify the type of epithelium. 2 Directly below the epidermis is the dermis of the skin. The deep region of the dermis is composed of dense irregular connective tissue. This type of connective tissue consists mostly of collagen fibers, although elastic and reticular fibers are also present. How does the arrangement of the fibers...
4. The avascular (no blood vessels) layer of the skin is a. Hypodermis b. Subcutaneous layer c. Dermis d. Epidermis e. Both A & B
How thick is the epidermis, in number of cells? Its thickness is not uniform so give a range from minimum to maximum. 12. What kind of epithelial cells does the epidermis contain? 13. What is different about the cells that make up the outermost layer of the skin when compared to these epidermal cells? 14. Compare the structure of the dermis to the epidermis. What structures are found in the dermis? 15. What is the structure of the hypodermis like...
The skin is the first line of defense against pathogenic invaders. Below give the pathogens which invade the epidermis layer, the hair follicle, sebaceous gland, and the fascia in the subcutaneous layer.
6. Name the specific sub-layer of the epidermis where mitosis occurs. 7. Describe functions of the dermal papillae: 8. Identify and label the photographs of the skin model to compare thin vs. thick skin: dermis, stratum corneum, stratum basale, dermal papillae, Meissner's corpuscle, duct of the sudoriferous gland, stratum spinosum, arrector pili, sebaceous gland, stratum granulosum, hair root, stratum lucidum 9. List the differences between thin and thick skin. Thick skin Thin skin Structure Epidermal thickness Layers of the epidermis...
