What is the function of the Uncalcified Genicula?
Non-calcified “genicula” serve as “knees” or hinges between the calcified intergenicula. The geniculate or non-geniculate form of algae was used to classify them; however either form has been convergently derived many times. The genuculae sometimes contain lignin.
What is the importance of coralline red algae?
Some red algae, like the coralline algae, deposit calcium carbonate in their cell walls. This prevents them from being eaten and gives them strength and support. These algae make an important contribution to the growth of coral reefs.
What eats red coralline?
Coralline algae play an important role in the ecology of coral reefs. Sea urchins, parrot fish, and limpets and chitons (both mollusks) feed on coralline algae.
What are 2 types of coralline algae?
Coralline algae take two different forms. Articulated species grow upright and have “branches” with flexible, uncalcified joints that withstand strong water motion. Crustose species encrust mostly on rocks, although they may also grow on plants or animals.
What is Genicular nerve?
The word “genicular” refers to the various arteries (femoral and popliteal) and nerves that feed into the knee. For people with knee osteoarthritis, the pain signals delivered by these nerves can become unbearable. A genicular nerve block temporarily blocks the nerve signals in the knee.
What does red algae do to humans?
Can I swim in the ocean when there’s a Florida red tide bloom? Swimming is safe for most people. However, the Florida red tide can cause some people to suffer skin irritation and burning eyes. People with respiratory illness may also experience respiratory irritation in the water.
What is coralline algae and what does it do for reefs?
Coralline Algae is a crustose type algae due to its hard calcareous deposits contained within its cell walls. It acts as the cement which binds the reef materials into a sturdy structure which will protect the reef and corals from breaking up or dislodging during intense wave action.
What is Coraline in saltwater tank?
Coralline Algae is a type of red Algae in the order Corallinales. It is a desirable algae to have in a saltwater aquarium and its growth is an indication of a properly matured marine fish tank. It is commonly introduced into an aquarium by placing live rock into the aquarium.
Why is live rock purple?
Coralline algae is a hard crust-like algae that is purple in color and grows over live rock. Another method is to seed your tank with coralline algae and/or use a booster to help accelerate growth.
What is Genitofemoral nerve block?
Genitofemoral nerve blocks are minimally invasive injections intended to relieve chronic pain in the groin or pelvic region. These nerve blocks can help in the diagnosis of chronic groin, testicular, penile, and pelvic pain conditions.
Where are genicular nerves?
The knee joint is innervated by the articular branches of various nerves, including the femoral, common peroneal, saphenous, tibial, and obturator nerves. These branches around the knee joint are known as genicular nerves. Several genicular nerves can be easily approached with a needle under fluoroscopic guidance.
