INTEGUMENTARY SYSTEM
Cards (44)
- It is the body's outer protective covering.
- It plays a crucial role in regulating body temperature (homeostasis).
- This organ system is vital for safeguarding the body and maintaining its health.
- What Latin word is the term "Integument" derived from?
- It means covering or garment.
- This layer is located at the outermost layer of the skin and provides the first barrier of protection from the invasion of substances into the body; keeps your body hydrated; and produces new skin cells that produce melanin.
- What does the Ancient Greek word "Epi" mean?
- What does the Ancient Greek word "Derma" mean?
- It is the middle layer of your skin. This layer is the thickest. It contains sweat and oil glands and hair follicles.
- It is the bottom layer of your skin. It’s the fatty layer of your skin that helps insulate your body.
- The top layer of your skin. This is the part of your skin that you can see and touch. It’s made up of three types of cells: melanocytes, keratinocytes and Langerhans. It gives your skin its color and provides a waterproof barrier.
- Where does Keratinocytes originate?
- This type of cell in the epidermis is located at the basal layer; it produces melanin which is a brown pigment responsible for the skin color, hair, and eyes. It also absorbs and scatters UV radiation from the sun.
- This type of cell in the epidermis is located in stratum spinosum. These cells prevent pathogens from getting to the skin.
- Where are the langerhans cells located?
- This type of cell in the epidermis is found in basal layer. It focuses on skin areas associated with touch sensation.
- It is the outermost layer of epidermis, which consists of 20 to 30 sheets of cornified cells. They continuously shed and are replaced by newer dead cells coming from below. Its function is to protect us from basic environmental harms, such as abrasions, UV rays, and pathogens.
- It is a layer of epidermis which is also called as "clear layer." It can only be found in thick areas of our skin. It consists of 2 to 3 layers of almost dead cells that are becoming less round and have a flatter shape. It carries a protein called "eleidin."
- What protein is being carried by Stratum Lucidum?
- It is a layer of epidermis which is also known as the "prickle cell layer." It consists of 8 to 10 cell layers located just below the stratum granulosum. It contains polyhedral-shaped keratinocytes connected by desmosomes which are abundant in this layer compared to others.
- It is a layer of epidermis consisting of 3 to 5 cell layers. This is where the process of keratinization begins. Keratonicytes that go here become flatter and hardnes as they receive granules from this layer.
- This layer of epidermis is also known as Stratum Germinativum. It consists of a single layer of cube-shaped Keratinocytes called as Basal Cells. It also contains melanocytes and merkel cells.
- Stratum Basale is also known as...
- It is the second and the thickest layer located between the epidermis and hypodermis. It is divided into two layers, and it houses hair follicles, blood capillaries, sweat glands, sebaceous glands, and nerve endings.
- It is the thin top layer of the dermis. It comprises collagen fibers, fibroblast cells, fat cells, nerve fibers, blood vessels, Meissner corpuscles, and phagocytes. It contains finger-like projections called dermal papillae.
- It is a finger-like projections found in the Papillary Dermis.
- It is the thick bottom layer of the dermis. It is composed of densely-packed collagen fibers. It has dense irregular connective tissue.
- It is also known as the subticus or subcutaneous tissue. It is the innermost layer of the integumentary system, and is primarily composed of adipose tissue, connective tissue, and blood vessels. It provides insulation, anchorage, and shock absorption.
- The hair is made up of a protein called...
- It is a filamentous structure that is made up of a protein called keratin. It serves as mechanical protection for the skin; increases sensory function; and aids in regulating body temperature.
- It is the part of your hair you can see, touch and style.
- It is the tube-like structure that keeps your hair in your skin.
- It is located under your skin and responsible for hair growth.
- Just like hair, this organ is also made up of a protein called keratin. It protects the fingers and toes while increasing the precision of movements and enhancing sensation.
- This organ can be found throughout your skin. They release materials like water, salt or oil from under your skin to the surface of your skin.
