How the Arm and the Leg are Adapted for Their Special Function

How the arms and legs adapt to their special function The arms and legs are adjusted in various ways to suit each function. The main function of the lower limb is to support the weight of the body, to provide a stable foundation for standing, walking, running. Therefore, in lower legs, we find that in general, adaptation to stability takes precedence over adaptation to mobility. Because the upper limb is a manually moving organ, it is an articulated lever that freely moves the upper body of the shoulder joint.

Special weapons: When an animal is attacked, it protects itself with all the weapons it has (arms, legs, feathers, hooves, teeth, claws, horns, etc.). Some animals further adapt to self-defense and develop other forms of defense. Porcupine feather pen has a hook at the end. If the predator is too close, the porcupine releases badminton to the carnivore, and if the porcupine escapes it can relieve the pain. Chemoprotection: Some animals and insects use chemoprotection. When attacked, some people may exhale, spray or spray chemicals that may cause pain and discomfort to birds of prey. Many snakes have poison, which can make an attacker stunned, numb or cause sputum when it is injected into the skin. Skunk uses scents to protect itself. They produce a powerful liquid called musk. Musk is made of glands near the tail and stored. If other animals are too close, the skunk lifts the tail and spews it out of the glands.

Algo Hero is an octopus. This type of woman has a beautiful outer shell, but male Algo Hero is more adaptable. They have special arms that are used to transfer sperm to women. This arm has its own tail and sensory organ that leads it to a woman. Arms fell off the octopus, then swim to the lady and suck sperm into her body. Male, basically no sex

It is suitable for the body of the earth with four legs (four legs) climbing a tree (young). These indications include arms and shoulders (lighter bodies, young gorillas) that allow them to gently shake from one branch to another, the long bent fingers used to grab and strongly build the branches Contains the toe's bone supporting its larger weight and walking with knuckle, they support themselves with their fingers' joints. Chimpanzees have two kinds of creatures - Pan troglodytes of common chimpanzees and Pan paniscus of chimps of Bonobo or Pygmy. Chimpanzees live in western forests and forests in western and central Africa. A chimpanzee is the smallest among gorillas and our closest relatives. Its functions are as follows.

The body is suitable for climbing trees and it is also suitable for movement of 4 legs (4 legs) on the ground. These adaptations include: Arms and shoulders to allow branching from one branch to another (especially with young, light chimpanzees), long bent fingers and toe bones for powerfully gripping branches ; And co-walking, they support themselves with their own fingers
