In human body, a joint is defined as a location where two or more bones meet and connect. The range of motion of joints refers to the measurement of the maximum distance and direction a particular joint can move. Most joints are connected in such a way that they allow movements in specific directions only.
The quantity of movement through a normal range for each joint is measured in degrees using an instrument called goniometer. Scientists had established standard range of motion values for most joints.
For ankle joint, downward movement of the joint, which is called plantar flexion ranges from zero to 50 degrees while the movement upward, which is called dorsiflexion ranges from zero to 20 degrees.
Wind and water take the heat away and it makes it cold! Hope this helps if I'm wrong I'm sorry
The organelle described in this problem is the MITOCHONDRIA.
The Mitochondria is found in almost all eukaryotes. It is a double-membrane bound organelle whose outer layer is smooth while the inner layer is highly folded.
Its main function is to produce energy from the oxidation of glucose substances and release ATP.
The herpes virus infects the humans to cause chickenpox disease. The virus during its stage of causing infection, it spreads through the epidermal cells by infecting them. This causes the typical rash on skin that is seen in chickenpox. The virus then enters that sensory nerves present on the ski and travels along the length of the neurons to the sensory dorsal-root ganglia adjacent to the spinal cord. Here the virus stays in an inactive stage.
