  1. Skeleton

  2. ENDO SKELITON To know that humans and some other animals have bony skeletons inside their bodies. Know that humans and some other animals have bony skeletons inside their body To understand the role of both kinds of skeletons. To recognise the main parts of these skeletons.

  3. These are all the animals that has a endoskeleton. Other endoskeleton animals And the animals bone is in side the body . But a exoskeleton is outside the body.

  4. An exoskeleton is a hard covering that supports and protects the bodies of some typeKnow that other animals have skeletons on the outside of their bodies (exoskeletons) Exoskeleton.

  5. Did you know you have more than 600 muscles in your body? They do everything from pumping blood throughout your body to helping you lift your heavy backpack. You control some of your muscles, while others like your heart do their jobs without you thinking about them at all.smooth muscles are at work all over your body. In your stomach and digestive system, they contract (tighten up) and relax to allow food to make its journey through the body. Your smooth muscles come in handy if you're sick and you need to throw up. Muscles around your body.

  6. You have three different types of muscles in your body: smooth muscle, cardiac muscle, and skeletal muscle. Muscles are grouped together in pairs on your skeleton. Muscles types When one muscle of a pair contracts, the other relaxes. When your biceps muscle in your upper arm contracts, it pulls your lower arm in towards your shoulder. However, when it relaxes, your biceps cannot push your arm back out.

  7. Ball and socket joints: Are the most mobile type of joint in your bodyMany different types of joints exist in the human body, but the kind which allows the greatest range of motion is the ball and socket joint. These joints are present where one bone ends with a spherical knob that lies in a circular depression in the other bone. This arrangement theoretically allows for 360 degrees of rotation. BALL AND SOCKET

  8. any animal lacking a backbone or notochord; the term is not used as a scientific classification. INVERTABRATES

  9. 1. any cold-blooded vertebrate of the class Amphibian, comprising frogs and toads, newts and salamanders, and caecilians, the larvae being typically aquatic, breathing by gills, and the adults being typically semi terrestrial, breathing by lungs and through the moist, glandular skin. amphibian

  10. any warm-blooded vertebrate of the class Aves, having a body covered with feathers, forelimbs modified into wings, scaly legs, a beak, and no teeth, and bearing young in a hard-shelled egg. BIRDS

  11. any of various cold-blooded, aquatic vertebrates, having gills, commonly fins, and typically an elongated body covered with scales. fish

  12. any vertebrate of the class Mammalia, having the body more or less covered with hair, nourishing the young with milk from the mammary glands, and, with the exception of the egg-laying monodramas, giving birth to live young. mammals
