Hair follicle: The tube-like structure that keeps your hair in your skin. 5.3 Functions of the Integumentary System - Anatomy and Physiology 2e | OpenStax. What is the function of sebaceous glands? The apical cells appear squamous, whereas the basal layer contains either columnar or cuboidal cells. Mucous, sweat, saliva, and breast milk are all examples of secretions released by exocrine glands. Stratified cuboidal epithelium and stratified columnar epithelium can also be found in certain glands and ducts, but are relatively rare in the human body. In contrast, the skin houses various exocrine glands that have ducts to allow them to secrete substances to the epithelial surface.

The direct cutaneous are derived directly from the main arterial trunks and drain into the main venous vessels. Describe the structural characteristics of the various epithelial tissues and how these characteristics enable their functions. The liver converts cholecalciferol to calcidiol, which is then converted to calcitriol (the active chemical form of the vitamin) in the kidneys. It also sends white blood cells to injuries to begin the healing process. Multicellular exocrine glands are composed of two or more cells which either secrete their contents directly into an inner body cavity (e. Kaplan chapter 2 cells tissues and integument. g., serous glands), or release their contents into a duct. Further subdivides into two layers. What do the sudoiferous glands do? What are subcutaneous tissues? Eumelanin is the dominant pigment in brown hair and black hair, and pheomelanin is the dominant pigment in red hair. Pathophysiology and Injury eg. Resident immune cells, both myeloid and lymphoid cells are present in the skin, and some, eg Langerhans cells or dermal dendritic cells, can travel to the periphery and activate the greater immune system [1].

Eccrine sweat glands: These simple, coiled, tube-like glands reside throughout the body. The epidermis and dermis are the two distinct layers of the skin. Pathophysiology eg Seborrheic dermatitis, Hyperhidrosis. Explain why waxing or tweezing body hair — which typically removes hair down to the root — generally keeps the skin hair-free for a longer period of time than shaving, which cuts hair off at the surface of the skin. Martini FH, Nath, JL. The bulb consists of two parts: germinal matrix and the upper bulb. For any form of armor, a breach in the protective barrier poses a danger. The Integumentary System (Skin, Hair, Nails): Anatomy and Function. The vast blood supply in the skin can help regulate temperature; as the blood vessels dilate, it allows for heat loss. Digestive System The skin synthesizes vitamin D (from exposure to the sun) therefore providing this vital nutrient to the digestive system. Glands The integumentary system has four types of exocrine glands, which secrete some type of substance outside the cells and body.

Ciliated columnar epithelium is composed of simple columnar epithelial cells that display cilia on their apical surfaces. Identify three main functions of the integumentary system. Sample answer: Keratinocytes are found in the epidermis and produce keratin to provide a waterproof, protective layer. 2019;9(3):127-143. doi:10.

Kaplan Chapter 2 Cells Tissues And Integument

Mastering the diverse knowledge within a field such as anatomy is a formidable task. Sample answer: Several examples of how nails are related to health are: the colour of the nail bed can be used to quickly assess a patient's oxygen and blood flow; how the nail plate grows out can reflect recent health problems; and nails can absorb several harmful substances that can cause health problems. Despite the risk, the practice of piercing the skin for decorative purposes has become increasingly popular. Skin cancer is more common than all other cancers combined.

Skin rashes and dry skin. Ceruminous glands: These are the glands in your ear that secrete ear wax. It's also known as seborrheic dermatitis. The cells responsible for the transmission of the nerve impulse are ________. It also contains numerous sensory nerve endings, such as Merkel endings and Meissner's corpuscles. They include distal subungual, proximal subungual, white superficial and candidal. Describe their functions. Striations, cylindrical cells, and multiple nuclei are observed in ________. Commonly referred to as subcutaneous tissue. Describe hair follicles. Vitamin D Synthesis. A gland is a structure made up of one or more cells modified to synthesize and secrete chemical substances. Vitamin D is required to absorb calcium and the skin works with the digestive system to ensure that calcium can be properly absorbed.

This article will discuss all of these components in detail together with some clinical notes about them and the integumentary system as a whole. Mucocutaneous junctions. Transitional epithelium is found only in the urinary system, specifically the ureters and urinary bladder. Metabolism Skin metabolism is the rate at which new skin cells turn over; this occurs between the epidermal and dermal cells that work together to regulate collagen production and repair UV light damage, aging, and other damage caused to the skin. In epithelial tissue, cells are closely packed with little or no extracellular matrix except for the basal lamina that separates the epithelium from underlying tissue. Compare and contrast the hair root and hair shaft. The cells are long and narrow. The nail bed: The skin that lies beneath the nail plate. The sudoiferous glands, also called sweat glands, exist to keep the body cool. What do nails consist of? Hair bulb: Located under your skin and responsible for hair growth.

What are two ways in which the integumentary system protects the body against UV radiation? Exocrine glands are classified by the arrangement of ducts emptying the gland and the shape of the secretory region. Basal cell carcinoma and melanoma both start in the stratum basale layer of the epidermis.

In addition to the number of ducts present, multicellular glands are also classified based on the shape of the secretory portion of the gland. Recall that sweat glands, accessory structures to the skin, secrete water, salt, and other substances to cool the body when it becomes warm. The hair root plexus surrounding the base of the hair follicle senses a disturbance, and then transmits the information to the central nervous system (brain and spinal cord), which can then respond by activating the skeletal muscles of your eyes to see the ant and the skeletal muscles of the body to act against the ant. Your integumentary system consists of the following glands: - Sudoriferous glands: These are the glands that secrete sweat through your skin. The layer after that is the stratum granulosum, in which cells are nearly filled with keratin and starting to die. Respiratory system: The tiny hairs lining the nasal passages remove harmful particles before the lungs inhale them. Sample answer: Since UV radiation causes the vast majority of cases of skin cancer, the risk of skin cancer can be reduced by avoiding exposure to UV light.
