21.How does bone grow and develop? ( Interstitial vs Appositional growth)
How does bone grow and develop? The chondrocytes, in the region next to the diaphysis, age and degenerate. Osteoblasts move in and ossify the matrix to form bone. This process continues throughout childhood and the adolescent years until the cartilage growth slows and finally stops. When cartilage growth ceases, usually in the early twenties, the epiphyseal plate completely ossifies so that only a thin epiphyseal line remains and the bones can no longer grow in length. Bone growth is under the influence of growth hormone from the anterior pituitary gland and sex hormones from the ovaries and testes. Whats the difference between Interstitial vs Appositional growth? Interstitial growth is the increase in the length of bones by the cartilage lengthening and is replacing by bone tissue while appositional growth is the increase in the diameter of bones by the addition of bony tissue at the surface of the pre-existing bone. So, this is the key difference between interstitial and appositional growth. Interstitial growth allows bones to grow in length, while appositional growth allows bones to grow in diameter. Moreover, interstitial growth occurs within lacunae while appositional growth happens on the surface of pre-existing cartilage.
I found this topic extremly fascinating mainly because i never knew the proper name of this process or how it worked im actually glad that I took this particular discussion. its also a lot more things that could have been added to this discussion but these are the main key points that were needed to explain how it works. I wanted to know more aboutthis topic because when I was younger i use to wake up in the middle of the night and my legs would hurt so bad. My mother reffered to the pains as growing pains but I never found anything that made any of that factual. I also never found anything that the denied these allegations either so that will just remain a mystery for now.

#8: Importance of the Functions of Integumentary System
Claimed Topic: Importance of the Functions of integumentary system
The Integumentary System is broken down into different layers Epidermis, Dermis, and Subcutaneous. Each layer plays a domino effect within the integumentary system, as far as protecting and when damaged it may affect each layer. The glands within the integumentary system also play a vital role in learning the system. Cleveland Clinic goes into further depth “Your integumentary system helps you absorb vitamin D, which acts as a hormone is crucial to your bone health because it affects calcium absorption.” Our skin helps captivate vital vitamins we need in order to remain healthy and strong. However, too much exposure to these vitamins can cause negative effects to the integumentary system. This system also is what makes up our nails and hair. These glands work to protect scalp infection and injury.
Disorders can happen when the integumentary system is exposed or injured in any way. The following illness/ disorders can occur: “skin cancer, skin rashes, wounds, poison ivy.” These are just listed within the Cleveland Clinic article that helps us understand what can happen when the skin is harmed. Which is why specialists try to implement sun screen as well as creams to keep our skin protected since it is at the forefront.
The basic foundation of what the Integumentary System is would be skin. Without even realizing skin is one of the primary things we notice about a person, not as far as color. However if someone walked up to you with no skin at all you’d probably scream. Skin is a vital protection for our organs on the inside, the various layers are created to resist from burns, cuts, or blisters that may happen on a day to day basis. Our skin is what keeps us alert as far as if something maybe crawling on us, climate temperature, and even if we are feeling ill. This system acts as a primary alert if something is going wrong with our body. As I stated in my research portion, our skin absorbs vitamin D. Personally I don’t prefer to be outside too long, however when I am in direct sunlight I do try to stay within shaded areas and put on the proper protection. Hats have become a big part of my wardrobe due to the fact that my face gets extremely sensitive especially around the summertime. From the extreme dry heat and the weather change. South Florida is typically hot however when summer begins the heat becomes unbearable.
