The stratum basale, also called the stratum germinativum, is the basal (base) layer of the epidermis. True: The outermost sheath of a hair follicle is … A. Dermal papillae . The Merkel cell is a fourth, less visible, epidermal cell. Integumentary System Quizlet CHAPTER 5: The Integumentary System Skin The skin and hairs and other structures such as nails constitute the integumentary system. The epidermis forms an undulating appearance, with intermittent regular protrusions of the epidermis layer ( rete ridges or pegs) into the upper layers of the underlying dermis. Rete Ridges and epidermal ridges are interchangeable terms and refer to the epidermis, not the dermis. C. Dermis . Which of the following do NOT derive from epidermal tissue? The epidermis is the outermost of three main skin layers.The outermost one is called the epidermis. The principal parts of the skin are the superficial epidermis and deeper dermis. Outer most layer . ... Found in the upper dermis, looks like parallel rows. They are genetically determined, therefore unique to each person. The stratum basale is the deepest layer, while the stratum corneum is the outermost layer of epidermis. It is the layer that’s closest to the blood supply lying underneath the epidermis. Bodytomy takes a closer look at these layers along with their functions. B. The pale stained regions indicated by the arrows are projections of the papillary dermis known as dermal papillae. Stratum Basale. Which of the following cells would one NOT expect to find in the dermis? The dermis overlies and attaches to the subcutaneous (subQ) layer. C. Cyanosis . Skin — together with hair, nails, and glands — composes the integumentary system. The epidermis, which contains no blood vessels, is made up of layers of closely packed epithelial cells. epidermal ridges: [TA] surface ridges of the epidermis of the palms and soles, where the sweat pores open. Which of the following statements is true regarding these prints or ridges? False: The dense fibrous connective tissue potion of the skin is located in the reticular region of the dermis. Epidermal Page 12/27 Credit: Illustration by Kathryn Born, MA From the outside in, these layers are the following: Stratum corneum (literally the “horny layer”) is about 20 layers […] Skin surface markings that reflect points of tight dermal attachmetn to underlying tissues are called epidermal ridges. Human skin: This image details the parts of the integumentary system. Which is the correct sequence of epidermal layers of thick skin, from deep to superficial? You get new skin every 15-30 days . 15. Which of the following epidermis components possesses a waterproofing glycolipid that functions in preventing water loss? The design of a person's epidermal ridges is determined by the manner in which the papillae rest upon the dermal ridges to produce the specific pattern known as handprints, footprints, and fingerprints. A. Synonym(s): cristae cutis [TA], papillary ridges ☆ , epidermal ridges , skin ridges B. Epidermis layer . The epidermis, which is the topmost layer, actually has 5 sub-layers. They contain blood vessels and are the site of sensory neurons (meissener’s corpuscles). D. Clear layer that covers granulosum. It’s thin but durable and acts as a protective barrier … True. It binds skin layers together and forms ridges and grooves of fingerprints . BIOL 223 - Chapter 5-2 - Study Cards for Chapter 5 BIOL 223 CSN Dermal-Epidermal layer . B.
