What 4 tissues can be found in the integument?
The integumentary system consists of the skin, hair, nails, the subcutaneous tissue below the skin, and assorted glands.
What are integumentary sensations?
Through sensory receptors in the skin, we are able to detect temperature, pain, touch, and pressure. Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.
Where are the sensory structures found in the skin located?
The skin possesses many sensory receptors in the epidermis, dermis, and hypodermis, which allows for discrimination of touch such as pressure differences (light vs. deep). Other qualities of the external world assessed by skin sensory receptors includes temperature, pain, and itch.
What are the three structures of the integumentary system?
Your integumentary system is an organ that consists of a few main structures: skin, nails, hair and glands, along with the nerves and blood vessels that support them….Skin
- Epidermis: The top layer of your skin.
- Dermis: The middle layer of your skin.
- Hypodermis: The bottom layer of your skin.
What are the accessory structures of the integument and what are their functions?
Key points
- Accessory structures of the skin include the hair, nails, sweat and sebaceous glands.
- Hair’s primary functions are protection, warmth and sensory reception.
- Nails protect the tips of the fingers and toes.
- The two main types of sweat gland –eccrine and apocrine – are responsible for regulating body temperature.
What are the structures of the integumentary system?
Your integumentary system is an organ that consists of a few main structures: skin, nails, hair and glands, along with the nerves and blood vessels that support them.
What are the structures of the integumentary system appendages?
The skin appendages include sweat glands, nails, and the pilosebaceous unit of the skin, comprised of the hair shaft, hair follicle, sebaceous gland, and arrector pili muscle — these appendages derive from a down growth of the epidermis beginning in the third month of fetal life.
Which of the following are sensory structures in the skin?
The skin acts as a sense organ because the epidermis, dermis, and the hypodermis contain specialized sensory nerve structures that detect touch, surface temperature, and pain.
What are the two types of sensory receptors in the integumentary system?
Sensory receptors in the skin include those for pain, pressure (touch), and temperature. Deeper within the skin are Meissner’s corpuscles, which are especially common in the tips of the fingers and lips, and are very sensitive to touch. Pacinian corpuscles respond to pressure.
What are the structures of the skin?
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
What are the 4 accessory structures of the skin?
Accessory structures of the skin include the hair, nails, sweat glands and sebaceous glands.
Which is are accessory structures of the integumentary system quizlet?

What are the 4 main functions of the skin?
Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances. Prevents loss of moisture. Reduces harmful effects of UV radiation. Acts as a sensory organ (touch, detects temperature).
What is the integumentary system structure?
Your integumentary system is your body’s outer layer. It consists of your skin, hair, nails and glands. These organs and structures are your first line of defense against bacteria and help protect you from injury and sunlight.
What are the appendages of the integumentary system and their functions?
The skin appendages, such as hair follicles, sweat glands, and sebaceous glands, make the skin function well in touch, temperature sensation, excretion, perspiration, and thermoregulation.
What are four functions of the skin quizlet?
Protection, maintenence of body temperature, excretion, perception of stimuli. The skin covers the body and acts as a physical barrier that protects underlying tissues from physical damage, ultraviolet rays, and pathogenic invasion.
