What are the two connection structures? |
• cardiovascular system (blood vessels in the dermis) • Nervous syetem (sensory receptors for pain, touch, and temperature) |
|
|
|
What is the hypodermis? |
-Loose connective tissue -Below the dermis -Location of hypodermic injection -Separates integuemnt from the deep fascia |
|
|
|
What are the functions of the skin? |
Protection Excretion (glands) Maintenance of body temperature Production of melanin and keratin Sysnthese of vitamin D3 Storage of lipids Detection of touch, pain, pressure and temp |
