The cartilage makes it possible for the diaphysis to grow in length, thus the epiphyseal plate is also known as the growth plate. Once growing stops the plate calcifies and is now called the epiphyseal line in adults. 4) Spongy bone tissue is very vascular and contains red bone marrow. Trabecular bone is another name for spongy bone tissue. The functional and anatomical unit of the spongy bone is the trabecula.

The epiphysis is filled with red bone marrow, which produces erythrocytes, or red blood cells. The epiphysial plate, also known as the growth plate, is located where the epiphysis meets the metaphysis. • Metaphysis is the portion of a long bone between the epiphyses and the diaphysis. In a growing bone, the metaphyses are regiouns that include "epiphyseal plate" (growth plate) at the point where cartilage is replaced by bone. This plate is a layer of hyaline cartilage that allows the diaphysis of the bone to grow in length but not in width.
Stroke Awareness Health Assessment The self-risk assessment I chose to complete was about strokes. A stroke occurs when blood supply to the brain is temporarily interrupted or disturbed. Being that the brain requires a constant flow of oxygen any interruptions could prove to be fatal. The two types of strokes are Ischemic or hemorrhagic. An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically.
Alcohol has a biphasic effect on the human body which means that its effects change over time. First, alcohol typically produces feelings of relaxation and cheerfulness then once you drink more and more it can lead to dehydration, coordination problems, blurred vision and even death. One of the worse things I think it causes to your body is dehydration, you need water to stay alive and basically alcohol just sucks it all up. Dehydration can lead to electrolyte an imbalance which is why you get headaches and feel dizzy afterwards. This is also why you get a headache in the morning because your brain swells up from lack of water.
If you take in more than the recommended amount of fluoride you can develop fluorosis, “a condition in which tooth enamel becomes toughened, mottled and discolored.” (pg. 1 Brown) Prescription fluoride drops are available if you live in an area where the water has a small amount of fluoride or none at all. A good practice to have and that will be a factor to good dental health is “brushing after meals and snacks.” (pg. 1 Brown) This will eliminate “sugars and food particles from the tooth surfaces.” (pg. 1 Brown) Decay starts “when the bacteria that are always present in the mouth break down components of saliva.” (pg.
Iron, fluoride, selenium, manganese, zinc, iodine, cobalt, and copper are trace minerals. Trace minerals and macrominerals perform various functions. The most plentiful mineral in the body is Calcium. Calcium helps build strong teeth and bones. Calcium rich sources are dairy products and leafy green vegetables.
Bone tissue structure Bone is hierarchically organized. Zooming in the bone structure (Fig. 4a), we find the osteons or Haversian systems, which are the basic unit of structure of compact bone. Osteons consist of concentrically arranged layers, or lamellae, of compact bone tissue, that surround a central canal, the Haversian canal, where bone’s blood supplies and nerves can be found (Fig. 4b).
The process begins in the second month of embryotic development and uses hyaline cartilage that has already formed as models for bone construction. According to Al-Arabi, Cherif, Jedlicka and Aron (2006) Long bone development begins in the center of the hyalline cartilage shaft at a region called the primary ossification center. First, the perichondrium coering the hyaline cartilage is infiltrated with blood vessels and converts it to a vascularized periosteum. As a result, the underlying cells specialize into osteoblasts. Now ossification can begin.
“A balanced diet is important because your body’s organs and tissues need proper nutrition to work effectively. Without good nutrition, your body is more prone to disease, infection, fatigue, and poor performance.” (Balanced Diet) It is important that you get a sufficient amount of each nutrient, but you don't want to ingest an amount of nutrients either. Norman Hord said: "Excesses of all nutrients, from water, to iron, to water-soluble B vitamins, can potentially cause toxicities." GERD is a medical condition that typically affects the esophagus. It stands for Gastroesophageal Reflux Disease.
