My knee pops when i extend to straighten my leg its not painful but fell over and hit knee hard 2 years ago and it just doesn't look the same as my other knee seems fluidy any ideas?

You might have torn a ligament at that time. I tore 3 ligaments (ACL, PCL, MCL), and got fluid in it. You can have it drained at your family physican. My friend had hers drained. I have heard that its painful, but I never had mine drained. Just something to think about.

Does mitochondria have fluid?
There is fluidy matter in middle.It is called the matrix.
What does scanty brown fluidy menses mean?
It can mean two things:Your menstrual cycle is getting ready to beginYour menstrual cycle is ending
Is cerro azul AAA or pahoehoe?
Cerro Azul produces pahoehoe lava. This type of lava is a kind of basiltic lava. It flows quickly and is very fluidy. Coming from Galapagos Island in Ecuador, Cerro Azul is a shield volcano. It has erupted eleven main times in history- the latest eruption was in 2008. That's all I got.
Why is blood called a tissue?
Blood is a tissue, because the cells in your blood are working toward the same function of tissues.
How many calories are in a spoon of raw tehini?
Tehini, or sesame paste/sesame butter is extremely healthy but high in calories.. 89 calories per tablespoon- but if you add lemon , water spices to prepare it to a fluidy sauce (as is the most common way served) you can get a quarter of a cup out of it... drizzle it on salad, chicken, grilled veggies or use it as a replacement for mayo in sandwiches for a healthy punch!
How do you determine if a female guinea pig is pregnant?
The only exact way to know is to wait 60-72 days from the potential breeding and see if she has pups. Otherwise sometimes you can gently feel the abdomen for little fluidy lumps, but if you want that done take her to a veterinarian. At later stages in pregnancy your guinea pig's belly will becound very routund and she'll look "light bulb" shaped. X-rays later on in the pregnancy can be done to look for the fetal bones, however I don't think it's worth the risk or cost to do that.
Swollen knot on face?
As we speak, I have two on may face and they hurt. I looked up info on cystic acne but it stated that it's knots are soft and fluidy. Mine are hard as a rock. There is no pimple head on them and I am trying not to push them. I just started taking some Vitamin C and Daily vitamins and these are the first I had in a while. If they only appear at different times, then I would say that your diet or stress is causing them. I have been drinking a lot of diet mountain dews that may be causing mine.
How do the motions of the particles different between state of matter?
The particles determine the state by the speed of motion. The motion is changed by the heat or degrees it is for water. When water is frozen to 32 degrees Fahrenheit it changes to ice at the freezing point and the molecules move slower. When ice turns to water at the melting point the molecules move quicker. When water is heated to the boiling point it turns to gas and the molecules move quicker.
What is in the cell wall of plant cells?
Plant cells have cell walls composed mainly of cellulose.CELL MEMBRANE:- A thin, transparent, electron microscopic, elastic, regenerative and selectively permeable membrane, which forms the outermost covering of the cell organelles, called cell membrane or plasma membrane or plasma lamella. It lies just below the cell wall in the plant cell and forms outermost covering in the animal cell.Chemical composition of cell membrane:- Chemically, cell membrane are lipoproteinous i.e. they are chiefly composed of lipids and proteins. Lipid constitutes (40-79) %, protein (20-70) %, carbohydrates (1-5) % and water 20%. Phospholipids are the major lipids present in the cell membrane. The other lipids are Sphignolipids, Glycerol, Sterol, etc. The proteins are globular, structural, carrier and enzymatic. Carbohydrates are branched or unbranched Oligosaccharides.Some important structural model of cell membrane:-A. Lamellar Model:-i.Sandwich model:-This model was proposed by Danielli and Davson in 1935. This model was based on the physical and the chemical properties of the cell membrane. It states that: →cell membrane is a trilaminar structure having a phospholipid bilayer sandwiched by the two surfaces layer of the protein molecules.→ protein molecules are globular structures and provide stability to the cell membrane. →each phospholipid molecules have hydrophilic heads and hydrophobic tails. → the hydrophilic head of phospholipid molecules faces towards the opposite direction associated with protein molecules, and the hydrophobic tails held together by Vander Waal Force.ii.Unit membrane concept:-This model was proposed by Robertson in 1959. It is the improvement over Danielli and Davson model. It states that:- → all cell membrane have trilaminar structure. → the mucoid protein lie towards the external surface and the non-mucoid protein lie towards the internal surface. → the thickness of cell membrane is 75 Å having 35 Å phospholipid bilayer and 20 Å each protein layer.The lamellar model has not explained: →permeability to the water →protein and lipid ratio →active transport →unit membrane concept.B.Fluid mosaic Model: - It is the recent model of cell membrane proposed by Singer and Nicolson in 1972. It states that "plasma membrane is formed of protein icebergs in the sea of lipids". It's statements are:→cell membrane is trilaminar and proteinous structure.→phospholipid bilayer is fluidy in nature in which phospholipid molecules show: - transitional and flip-flop movement.→each phospholipid molecules have two specific ends; ●hydrophilic head of glycerol ●hydrophobic tail of fatty acid.→hydrophilic head of phospholipid molecules are directed oppositely, while the hydrophobic tails faces each other.→proteins are globular and are of two types: - ●Extrinsic or peripheral proteins ●Intrinsic or integral proteins.→carbohydrates (Oligosaccharides) are associated with outer surface of plasma membrane in the form of glycolipids or glycoproteins. They play important role in blood grouping, immune response, cancer and rejection of transplanted organs.Functions of Cell membrane:- Cell membrane is selectively permeable membrane which has following functions:-1. Cell adhesion:-ü Compartmentalization: Cell wall help in the partition of the different cells, which is known as compartmentalization.ü Bounding semi-fluid substances of the cell2. Ion conductivity:-ü Passive transport: It is a mode of membrane transport which occurs according to concentration gradient without any energy. It is of following types:-*Osmosis: It is a process of movement of mater molecules from higher water concentration to lower water concentration through semi permeable membrane.*Diffusion: It is the movement of ions or molecules from higher concentration to the lower concentration due to the tangency of molecules to spread uniformly. Both simple and facilitated diffusion occur through the cell membrane. E.g. Exchange of gases in cellular respiration (simple diffusion), entry of glucose into RBC through the agency of membrane protein (facilitated diffusion).ü Active transport: It is a mode of membrane transport which is energy gradient and requires energy. E.g. Salt uptake by plant cell.üEndocytosis: It is the process of active intake of material by membrane. It is of two types:*Pinocytosis: It is the intaking process of large sized liquid particles through membrane. It is also known as cell-drinking.*Phagocytosis: It is the intaking process of large sized solid particles through membrane. It is also known as cell-eating.ü Exocytosis: It is the expelling of materials from cell through cell membrane. It is also known as cell-vomiting or Ephagy.3. Cell signaling: - Cell signaling is a part of a complex system communication that governs basic cellular activities and coordinates cell actions. The ability of cells to perceive and correctly respond to their microenvironment is the basis of development, tissue repair, and immunity as well as normal tissue homeostasis. Errors in the cellular information processing are responsible for diseases such as cancer, autoimmunity and diabetes. By understanding cell signaling, diseases may be treated effectively and, theoretically, artificial tissues may be created.4. Locomotion:- The extension and folding of cell membrane help in the cellular pseudopodial locomotion in Amoeba, W.B.C. of blood, macrophages (phagocytes),etc. and undulatory locomotion shown by some mammalian cells such as fibroblasts.
