BIOL Exam 2 Final

QUESTIONS 14-15: For each diagram, color the structures with the indicated colors. 15. 14. Epidermis and dermis of skin Stratum basale = green Reticular layer=red Papillary layer=blue Stratum corneum = yellow Hypodermis - gray Dermis = purple Epidermis - blue Hair follicle green Sebaceous gland = red Sweat gland - brown Skin from the scalp Arrector pili muscle = orange Lamellated corpuscle = yellow Tactile corpuscle - black Hair root = pink Hair shaft = tan

DIRECTIONS: Match the letter of the description and/or function to the epidermal layer that defines it. A. Outermost layer of dead keratinocytes that protect the skin 6. Stratum basale B. Layer of skin composed of areolar and dense irregular connective tissues 7. Stratum spinosum C. Layer of keratinocytes that undergo apoptosis via keratinization 8. Stratum granulosum D. Single layer of active stem cells that undergo somatic cell division 9. Stratum lucidum E. Layer of skin composed of adipose and areolar connective tissue 10. Stratum corneum F. Layer of keratinocytes with intermediate filaments to resist tension G. Layer of clear, flat, dead keratinocytes found only in thick skin

How should a paramedic handle skin medication?(name at least 4 factors).

Identification of Skin Structures:   1. Epidermis Layers (from superficial to deep) Tissue type:   Stratum Corneum Types of cells? Functions?   Stratum Lucidum Types of cells? Only fouond where?   Stratum Granulosum Types of cells? What do they produce?   Stratum Spinosum Types of cells? What protective cells are found in this layer?   Stratum Basale 3 types of cells? a. b. c. What processes occur here?   2. Dermis Layers   Papillary layer Type of tissue? Sensory cell type found here?   Reticular Layer Main tissue type? 2 gland types? a. b. Pressure receptor type? Blood vessels present or absent? Hair follicles and arrector pili present or absent?   3. Hypodermis (subcutaneous tissue under the skin) 2 tissue types: a. b. Blood vessels present or absent?

Answer the following questions. What is keratin?   Describe the process of keratinization.     Identify the 2 layers of the dermis. Describe their locations and the specific type of connective tissue that they are made of.   In which layer are melanocytes located? What is their function?     Identify all accessory structures located within the dermis. a) List the 2 types of sweat glands found in skin.     b) Explain the differences between the 2 types of sweat glands.     What type of tissue makes the ducts of the sweat glands?     What is the arrector pili muscle? What is its function?

Please answer this following questions in your own words:  Describe the layers of the skin and the functions of each layer, and describe the changes that occur in the integumentary system during the aging process?

Can someone help me with the following questions?

Briefly answer the following questions:1. Cells of the epidermis are derived from stem cells of the stratum basale. Describe how the cells change as they become integrated into the different layers of the epidermis.2. What structures are produced from keratinization of the epidermis?

Clinical Case Study, Integumentary System: 1. What protective mechanisms are impaired or deficient in the abraded areas? 2. Assuming that bacteria are penetrating the dermis in these areas, what remaining skin defenses might act to prevent further bacterial invasion? 3. What benefit is conferred by suturing the lacerations? 4. Mrs. DeStephano’s cyanotic skin may hint at what additional problem (and impairment of what body systems or functions)?

Hello, good day! I'm having a problem answering this question and I need your help with this. Hoping for a response and thank you so much.   The answer must be in 2 paragraphs and each paragraph much have 4 sentences. Question: Do keratinocytes produce melanin?

Answer the following questions about the integumentary system. Name each of the five sublayers of the epidermis in order from superficial to deep. For each layer, describe one unique characteristic and name the type of cells found there. Next, make a sentence to help you remember the order of the layers. Use the first letter of the second part of each layer (for example use the letter G for stratum granulosum) since they all start with "stratum." Put together a sentence with 5 words that start with the letters. For example I think "Please Make A Taco" to help me remember prophase, metaphase, anaphase and telophase.

Please answer together  1. Patient A and Patient B suffered different degrees of burn during an accident. Patient A had only the epidermis layer destroyed, while Patient B had both the epidermis and the dermis layers destroyed. Without skin grafting, will body hair grow back on Patient A?
