A+P 1 module 7- Integumentary Sysem 2023//2024 Identify the region and the layer of skin that is highlighted in blue. (Also indicated by the arrow, below) *NOTE: To receive full credit you must label two regions. Stratum granulosum; Epidermis *A- Identify the sensory cell receptor highlighted in blue, below, also indicated by the arrow. B- What sensory information is detected by this type of receptor? A) Pacinian corpuscle B) Detects pressure (mechanoreceptor) The layers of the epidermis, from superficial to deep are: Stratum corneum, stratum granulosum, stratum spinosum, stratum basale. Stratum basale, stratum spinosum, stratum granulosum, stratum corneum Stratum spinosum, stratum granulosum, stratum corneum, Stratum basale Stratum corneum, stratum spinosum, stratum granulosum, stratum basale. Stratum corneum, stratum granulosum, stratum spinosum, stratum basale. Endocrine glands secrete ______; Exocrine glands secrete ____. A. for body-wide distribution, into an epithelial lining B. into an epithelial lining, for body-wide distribution C. through a duct, into the bloodstream D. into the bloodstream, through a duct E. A&D F. B&C E. A&D Which of the following is true regarding the epidermis: It is highly vascular. It is comprised of five distinct layers. The basement membrane contains its blood supply. Epidermal ridges change throughout a person's lifetime. The basement membrane contains its blood supply. 1. Fibroblasts 2. Keratinocytes 3. Langerhans 5. Melanocytes 1. Produces collagen 2. Produces a protein to protect the skin 3. cells Assists in immune responses 4. Produces a pigment that absorbs UV rays A person senses pain from a sharp tack. What type of sensory organ detects this information? Nociceptor Main blood supply for the skin is found in what layer? Dermis (reticular region) In your own words, how can the skin be used to determine if a person is dehydrated? When a person is dehydrated he/she can test his/her skin by pinching the back of the hand and the hand doesn't recoil back to normal or it remains wrinkled or pinched. *What is the name and function of the structure below? (Highlighted in blue, also indicated by the arrow) it is the arrector pili muscle which is a smooth muscle that contracts when the body is cold or experiences emotional responses. *What is the name and function of the structure below? (Highlighted in blue, also indicated by the arrow) It is a sweat gland which produces sweat to most of the body and helps regulate the body's temperature via perspiration. All of the following are functions of skin except: Absorb UV rays Produce vitamin C Thermoregulation Protection for underlying tissues Produce vitamin C The most superficial region of the dermis is the: Reticular Papillary Stratum corneum Subcutaneous None of the above are layers o
