What are limbs? What are their functions

Answer: A limb (out from the Old English called lim), also known as an extreme point, is a hinged bodily appendage used by humans as well as numerous other animals for motility such as running, walking, and swimming, as well as prehensile grasping and climbing. Arms, as well as legs, as well as legs, are usually referred to as lower and upper limbs in the human body. The shoulders connect the arms to the trunk or torso, and the hip girdles connect the legs. Numerous animals could use their forelimbs (that are like human arms) to carry as well as manipulate objects, and some can fly. Some creatures can also change their hind limbs when they want.

Almost all further mammals run or walk on all 4 limbs, whereas human feet and legs are specially designed for 2-legged locomotion. Arms of humans are not stronger, but very portable, permitting hands to reach a vast range of areas as well as angles, and finished in specialized hands able to grasp as well as good manipulation an object.  human being dexterity is unusual, and grasping nature is mutual among tetrapods.

As a result, the function is self-evident. Humans practice their upper limbs or forelimbs for:

• Grasping
• Holding
• Eating
• Writing

While their lower limbs or hind limbs are being used for walking, running, as well as other activities. Animal limbs are similarly used for: 

• Eating
• Climbing
• Running
• walking
• jumping. 
• Flippers, wings, legs, arms — these remain samples of a limb.
