Temperature affects every single aspect of the human body. Regarding your hands, cold temperatures typically cause your body to shunt blood away from the non-vital parts of your body (as the body itself sees it) which causes your hands to have decreased circulation to all the tissue, including the muscles in your hands, due to what's called vasoconstriction, or constriction of the blood vessels. To put it simply, the decreased circulation causes the muscles to grow "cold" and become stiff. Hypothermia takes this concept into a larger degree. The lower the bodies temperature, the more noticeable the effects of muscles. The muscles themselves require a reaction of calcium ions and chemical reactions at the molecular level, along with a nervous impulse from the brain to work. Since a normal healthy body operates efficiently at 98.6 degrees Fahrenheit, naturally a decrease in the bodies internal temperature would decrease this efficiency slowing the nervous impulse from the brain that is required to initiate the chemical reactions in the muscles themselves to initiate. As the body grows colder in a hypothermic environment, the impulses from the brain slow dramatically causing miscoordination, and muscle weakness. Heat causes vasodilation, or, dilation of the blood vessels resulting in increased blood flow. This is one of the mechanisms the body uses to cool itself off. If the temperature outside the body gets hot enough, the body distributes the blood which is maintained at 98.6 by the hypothalamus of the brain, throughout the body in an attempt to cool the body off. This along with sweating plays a major role in temperature regulation within the body.
the factor that will affect it is temperature.
The hand muscles and tendons work together to control hand movement. Muscles provide the force needed to move the hand, while tendons connect the muscles to the bones, allowing the muscles to pull on the bones and create movement. The anatomy of the hand muscles and tendons determines the range of motion and strength of the hand. If the muscles or tendons are injured or not functioning properly, it can affect hand function and movement, leading to difficulties with tasks like gripping, grasping, and manipulating objects.
The extrensic muscles of the hand originate from the lateral epicondyle of the humerous
hand muscles -_-
A. Eye muscles
Yes it loosens up muscles and prevents them from tearing. Cold, stiff muscles tear much easier.
Energy travels from your hand to the cold surface. Cold is merely the relative absence of heat.
To effectively strengthen hand muscles using a finger hand gripper, consistently practice squeezing and releasing the gripper with varying resistance levels. Gradually increase the resistance as your hand muscles become stronger to continue challenging them.
A cold compress is good for swollen tissues. For tired muscles the best thing is heat or massage.
Writing at a slant involves BOTH your brain along with your arm and hand muscles.
talk to the hand..
The median nerve supplies most of the muscles in the hand. It innervates the muscles responsible for flexing the wrist and fingers, as well as the muscles that control the thumb.
