Organs of the Integumentary System (structure and functions) The integumentary system is composed of skin and its appendages, subcutaneous tissue, deep fascia, mucocutaneous junctions, and breasts. Unlike the other bodily systems throughout the body, the integumentary system is not localized to one area or region of the body; instead, the integumentary system covers the entire body. The hypodermis is the “connection” layer. Hair skin and nails c. Lamellated corpuscles, tactile corpuscles, and blood vessels d. Glands, Hair, and Nails 5. Image Source: Wikipedia. The integumentary system is composed of skin, hair, nails, and glands. This layer also contains specialized cells called Langerhans cells that signal to the immune system when there is an infection. Areas of the body in which the hypodermis is thick include the buttocks, palms, and soles of the feet. The epidermis is composed of five sublayers: The epidermis includes two distinct types of skin: thick skin and thin skin. The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. The inner layer is the _____ layer. (2020, August 27). https://oli.cmu.edu/jcourse/workbook/activity/page?context=4348901080020ca601df22a6f50e5f55, CC BY-NC-SA: Attribution-NonCommercial-ShareAlike. Within the basal layer are melanin-producing cells known as melanocytes. Skin. Which of the following is NOT an accessory structure in the integumentary system? ThoughtCo. Other components of the hypodermis include blood vessels, lymph vessels, nerves, hair follicles, and white blood cells known as mast cells. There is no direct blood supply to the epidermis and therefore, the cells of this stratified squamous tissue obtain nutrients and oxygen through diffusion. Skin is the largest organ in our body. Skin, which is the largest organ of the body is the main organ of the integumentary system as well.

List six functions your skin performs while it is "just lying there". List six functions your skin performs while it is "just lying there". The skin is made up of two mutually dependent layers that are distinguished based on their structure and location. It also helps maintain homeostasis within the body by assisting with the regulation of body temperature and water balance. The epidermis consists mainly of epithelial cells called keratinocytes, which produce keratin. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. The bilayered … An example is it using epithelial tissue as the outer layer of the skin. It contains epithelial, connective, muscular, and nervous tissues. These layers – the epidermis and the dermis – contain a variety of structures, including blood vessels, hair follicles, and sweat glands. Module 5.1: The integumentary system consists of the skin and various accessory structures Integumentary systemoverview Most accessible organ system Can be referred to as skin or integument 16 percent of total body weight 1.5–2 m2in surface area Body’s first line of defense against environment Has two major components 1. The Structure of the Integumentary System. The hypodermis also connects the skin to underlying tissues through collagen, elastin, and reticular fibers that extend from the dermis. This extraordinary organ system protects the internal structures of the body from damage, prevents dehydration, stores fat, and produces vitamins and hormones. All these structures together provide protection to the inner tissues of the body. 1. Skin may be one of the most underestimated organs in the body. Skin — together with hair, nails, and glands — composes the integumentary system. A major component of the hypodermis is a type of specialized connective tissue called adipose tissue that stores excess energy as fat. The integumentary system, better known to laypeople as “the skin,” is the largest of the body's organ systems and one of the most important. Beneath the dermis lies the hypodermis (subcutis). Breast growth and appearance in male and female children are virtually identical prior to puberty. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature. The epidermis is an avascular region of the body, meaning that it does not contain any blood or blood vessels. 2. Postnatally at puberty, female mammary glands under the influence of mainly sex hormone signaling, undergo a series of growth changes that can be defined anatomically by a series of "Tanner Stages". Beneath these two layers lies the hypodermis, composed of loose connective tissue (adipose and areolar). Learn vocabulary, terms, and more with flashcards, games, and other study tools. The integumentary system consists of the skin, hair, nails, glands, and nerves. What structures are included in the integumentary system? The integumentary system or integument is a focus topic of the event Anatomy.It came into rotation for the 2014, 2015, and 2016 seasons. What structures are included in the integumentary system? The outermost layer of the skin, composed of epithelial tissue, is known as the epidermis. It has a variety of additional functions; it may serve to waterproof, and protect the deeper tissues, excrete wastes, and regulate body temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. These layers – the epidermis and the dermis – contain a variety of structures, including blood vessels, hair follicles, and sweat glands. Gross Anatomy of the Integumentary System The skin is made up of two mutually dependent layers that are distinguished based on their structure and location. Split End c. Shaft d. Cuticle 6. Retrieved from https://www.thoughtco.com/integumentary-system-373580. Its main function is to act as a barrier to protect the body from the outside world. This layer contains adipose tissue and connective tissue as well as blood vessels, nerves and immune cells. Your skin (the body’s largest organ), glands, nails, and hair — also known as the integumentary system — serve as the “public face” of your body. The layer beneath the epidermis is the dermis, the thickest layer of the skin. Or as a barrier between the environment and human organs to prevent excessive fluid loss that will enter environments such … Define the integumentary system and name its accessory structures Describe the structure of hair and identify its components, both above and below the skin Summarize the functions of hair Carotene. Also found in the basal layer of the skin are touch receptor cells called Merkel cells. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature. Keratin is a major component of skin, hair, and nails. This aids in the development of antigen immunity. The integumentary system forms a protective barrier between the external environment and the inner tissues. Both layers of the dermis contain connective tissue components (collagen, elastin, fibroblasts), plus blood vessels, sensory receptors and lymphatics. The innermost layer of the epidermis contains keratinocytes called basal cells. Composed of fat and loose connective tissue, this layer of the skin insulates the body and cushions and protects internal organs and bones from injury. Epidermis. Keratinocytes on the surface of the epidermis are dead and are continually shed and replaced by cells from beneath. list six functions your skin performs while it is "just lying there" The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses.

The storage of fat helps insulate the body and the burning of fat helps generate heat. Skin may be one of the most underestimated organs in the body. What structures are included in the integumentary system? It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The integumentary system consists of the skin, hair, nails, glands, and nerves. The dermis might be considered the “core” of the integumentary system (derma- = “skin”), as distinct from the epidermis (epi- = “upon” or “over”) and hypodermis (hypo- = “below”).
