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